The majority of construction incommercial building today is

done by use of large building panelsof various types, connected by ahigh performance elastometric seal-ant material to form a waterproofseal. These panels consist of eitherprecast concrete, prestressed con-crete, or curtain wall which is pre-dominately glass and metal. Anycombination of these three typesalso is commonplace in modernconstruction.

It is vitally important that theconnecting link, the sealant, joiningall these panels be of top quality,capable of performing satisfactorilyfor a great many years. without thisperformance, water tightness soon islost, resulting in long, costly mod-ifications and repairs.

Many factors must be consideredin designing a commercial buildingwhich will give many years of trou-ble free service. These include jointdesign, selection of sealant, surfacepreparation of joints just prior tocaulking and, finally, selection ofthe proper backer rod (againstwhich sealant is placed). The rightdecisions in these important areas,plus proper installation of the prod-ucts, ensures desired results.

The backer rod evolves

Evolution of the backer rod from thefirst use of caulking to the present

Hidden, but essentialA technical reviewof backer rodsby J.F. Gibb

At left, the result of outgassingby a closed cell backer rod. Therod has been removed, and thepanels and sealant bead sawedin cross-section to showcavities caused by the bubbles.This is an unsatisfactory seal.Below, the sample at left seenfrom the side. A cured sealantbead applied above a closed cellbacker rod was ruptured whentrapped gases escaped from therod.

John F. Gibb invented and developedthe production equipment used to makeopen cell backer rods, and holds U.S.and foreign patents on this machinery.He is a member of the ASTM C-24 JointSealant Committee, and is GeneralManager/part owner of Backer Rod Mfg.& Supply Co., Denver.

state of the art covers use of manydifferent types of materials. Theyrange from sand in horizontal joints,through wood, fiber board, jute,rope, and twisted paper. About 17years ago, a product evolved whichconsisted of an extruded plastic rod.

This new backer rod was a closedcell, flexible foam material. At first,it was made from polyethylene plas-tic. Now it consists of polyethyleneand polypropylene, both nearlyidentical in appearance and per-formance. This new rod is manufac-tured by plastic extrusion: A gas isinjected into the material, creatingplastic foam. The result might bedescribed best as being somewhatsimilar to a tube inflated underslight pressure as gas is trappedwithin its cellular structure. Thisrod proved to be far superior to whathad been used previously in thetrade, but was not without its prob-lems.

Problems — and solutionsOne of the more serious problemswas outgassing. When these closedcells and their outer skin somehowbecome ruptured, trapped gasesslowly escape to the atmosphere. If ahigh proportion of these cells be-come ruptured or deflated (so tospeak), much of the rigidity of therod is lost. The rod also loses muchof its ability to regain its originalround shape once it has been de-formed.

The problem of outgassing as-sociated with these new flexible foambacker rods resulted in sealantmanufacturers insisting on furtherresearch, in the attempt to find asuitable material that would elimi-nate this problem — without creat-

ing even more serious ones.For many years, in limited appli-

cations only, polyurethane foammaterials had been used success-fully. This promoted further de-velopment of this material, to de-termine its suitability for use inbacker rods in the caulking busi-ness.

Most early applications em-ployed a backing material cut intoshort strips (square or rectangular incross-section). The material exhi-bited a wide range of physical prop-erties, because much of it had beencut from scrap material used by thefurniture business. The type ofpolyurethane used in that industry isrequired to have a very high de-gree of resilency, and to retain thisproperty through severe usage. Thissame property is necessary in ex-pansion joint backer rod. Therefore,it proved to be an ideal material forbacker rod use.

About six years ago, a round,open cell, flexible polyurethanebacker rod was introduced. Theproduct was made from specialformulations of these flexiblefoams, producing a more uniformmaterial. (As noted, uniformity waslacking in previous urethane backerrod produced from scrap.)

Open vs. closed cell

There are some interseting (and im-portant) differences between openand closed cell backer rods.

Both open cell and closed cell areinert to all common and more pre-dominately used sealant materials onthe market today. Both have ex-cellent chemical resistance.

Both, too, are classified as non-

staining. This means they containno materials that would bleed outslowly and seep into the sidewalls(substrate), later to reappear as dis-coloration on the surface (some dis-tance away). This is a particularlyimportant point, if marble or othermasonry materials are used.

The open cell rod is more flexiblethan its counterpart closed cell. Theopen cell must depend on its chem-ical and physical make up to attainrigidity, while closed cell rigidity isthe result of gases trapped in itsinterior (as explained earlier).

Rarely in commercial buildingconstruction do expansion jointwidths conform exactly to design.For instance, a one-half inch jointfrequently will vary from as little asone-quarter inch or less to as muchas three-quarter inch (or more). It isvirtually impossible to manufactureor to erect large building panelseconomically to such precise di-mensions that joints between suchpanels stay within close tolerances.A backer rod to be packed betweenthese panels must be flexibleenough for easy insertion.

Manufacturers of closed cellbacker rods recommend that theproduct not be compressed morethan 25 percent of its diameter. Con-sequently, the applicator mustchange sizes frequently, usingclosed cell in commonplace, vary-ing width joints, and open cell rod ifhe is to exceed the 25 percent max-imum compression limit.

Open cell backer rod must becompressed at least 25 percent; itdoes not hurt these rods to be com-pressed as much as 75 percent oftheir diameter. This allows theapplicator to use fewer sizes in vary-

ing width joints. Many times, onesize will work the full length of thejoint (which might not be the casewhen using closed cell rod).

Three primary purposesA backer rod has three primary pur-poses. First, it forms a base againstwhich sealant is applied. (It there-fore determines the thickness of thesealant bead.) Also, it forces un-cured sealant out laterally undertooling pressure, resulting in 100percent contact of sealant tosidewall (substrate). These are thebond lines. Finally, backer rodsdictate the cross-sectional config-uration of the sealant bead.

Flexibility of the two backer rodmaterials plays an important part intooling the newly applied sealantbeads. A backer rod, although im-portant in an expansion joint, issecondary to the primary prod-uct—the sealant. The desired endresult is a satisfactory seal thatmeets or exceeds specifications.

The more rigid closed cell backer

rod is able to withstand a heavierpressure. The greater flexibility ofthe open cell rod requires thecaulker to use lighter toolingpressure, to minimize spring back.(It is not a difficult technique tomaster, for open cell backer rod hasbeen used successfully for 20 yearsor more.)

Tooling the hour glassTooling is done with a variety of in-struments. Most incorporate asemi-flexible blade, like a spatula. Itis the tooling operation that givesthe cross-sectional shape to thenewly applied sealant bead. Thisshape is referred to as an “hourglass” configuration.

The hour glass shape is impor-tant. It results in a maximum bond-ing surface on the sidewalls, and athinner section midway between.This means the adhesive bond to thesidewalls will be of sufficientstrength to eliminate failure causedby repeated elongations and con-tractions of the sealant material. Insimple terms, the strength of the

bond to the sidewalls forces ellasticmovement of the sealant. Elasticityof the sealant comes into play by al-lowing stretching and contractionat the thinnest point, avoiding ex-cessive stress at the bonds to thesidewall. Choosing the correctbacker rod obviously plays an im-portant part.

If a backer rod is placed incor-rectly (too deeply) or so it doesn’tforce an hour glass cross section,cohesive or adhesive failure be-comes a distinct possibility.

Proper cross sectionsFigures 1 and 2 show the dif-ferences between the proper crosssection of a newly applied sealantbead, and an incorrect one. Figure 2is incorrect because the ratio ofthickness of the sealant bead at thebond line to that at the midwaypoint is too small. Movement of thejoint sidewalls will put undue stresson the bond lines. The high cohe-sive strength of the overly thicksealant bead will make it very dif-ficult or impossible for the sealant toelongate. The bonds may fail even-tually because of this; they will notif they have the correct ratio de-picted in Figure 1.

This problem can be com-pounded if an incorrect back-up isused in cases where three-sidedadhesion occurs. In these cases, asealant cures while adhered to bothsidewalls, and to the backer rod.When the back-up rod is composedof a rigid, unyielding material,problems can arise.

Closed cell backer rods, being anolefin-type plastic material, are wellknown for their anti-stick prop-erties. Usually, any inital adhesionto these back-ups break downquickly, and the sealant comes free.

This was thought to be the casewith open cell rods as well, sincethe weak open cell surface structurealso shears away from the sealantbead. In cases where it does not,however, the flexibility of the opencell rod allows it to move with thesealant bead (with absolutely no illeffects) for the life of the sealant.

This has been demonstrated both


in laboratory tests of 10,000 cycles(excess of 25 years) and in over 20years of actual use in the field. Prob-lems do arise when a rigid back-up isused: the sealant bonds to ittenaciously. When the joint moves,the sealant doesn’t—and failurelikely will occur.

Closed cell rods tend to take a setwhen compressed for extendedperiods of time. This is not the casefor open cell rods. It is a basic re-quirement of these open cell foamsin the furniture and padding indus-try that they not take a set. On occa-sion, closed cell rods have beenknown to move back into a jointunder gunning pressure, if the rodfirst was placed in the joint too far.(This permits too thick a sealantbead, risking bond failure.)

Open cell rods have a high coeffi-cient of friction, and do not slideeasily over most surfaces. This re-sults in a good grip to sidewalls, anda resistance to movement undergunning presuure. Open cell rod canmove, however, if it is not com-

pressed the recommended 25 per-cent in joint packing.

Moisture AbsorptionOne of the myths that existed foryears about open cell backer rod wasits alleged moisture absorption.Many felt its open cell structuremade it perform as a sponge. Opencell foam will absorb some water,but under most situations it does notretain it for long. Twenty-four hourtotal submersion tests indicate 50percent absorption is about average.(This, of course, is not encounteredin the field, but whatever watermight be absorbed in actual practicestill is not retained long.) Closed cellrod, on the other hand, is virtu-ally non-absorbent; therefore, noproblem.

This open cell feature has provento be an important asset, because anescape route for gases always isreadily available. Should somemoisture become trapped betweenthe sidewalls and the backer rod, thearea usually is much slower to dry

out than is that part of the joint notcovered by the backer rod—and ex-posed to the air. (See Figure 3 andFigure 4.) The portion to be caulked,however, is dry enough to be sealed.

When this moisture problem oc-curs and the wetness begins toevaporate, vapor pressure is built upbetween the backer rod and thesidewalls. In the case of the open cellrod, when these vapors take thecourse of least resistance they gothrough the backer rod to escape. Asfor closed cell, being impervious,the only escape route is through thenewly applied sealant bead. Whenthis occurs, the sealant bead blis-ters. Channels can developthroughout it; at times, the bond linefails or is seriously weakened.

Another important plus for opencell rod which became obvious in theapplication of air cured sealants(silicones) was the fact that a cure isinitiated from both sides. Thisspeeds up the cure substantially(highly desirable with slow-curingsealants). This faster cure to a largeextent eliminates precure adhesive orcohesive failure problems.

Two-sided curing is impossiblewith closed cell rod material, there-fore air curing sealants remain in anuncured or semi-cured state for alonger period of time. (See Figure 5and Figure 6.)

OutgassingBubbling of newly applied or semi-cured sealant beads is referred to asoutgassing. The results are similarto those caused by trapped mois-ture. This is a common problemwhen using closed cell rod. Formany years, it was suspected thisbubbling in newly applied sealantbeads was caused by the sealant.However, more precise observationshowed it to be from closed cellbacker rod.

It was explained earlier thatclosed cell backer rod containstrapped gases within its surface skinand inside its closed cells. Also, itwas pointed out that if this skinand/or some of these cells becomeruptured, the gas begins to seep out.The impervious nature of the closedcell backer rod prevents escaping


gases from going any place otherthan through the newly appliedsealant beads.

This seepage bubbles in the seal-ant, that, at times, can extend fromthe vent hole in the backer rodcompletely through the sealant bead,to its outer surface. This causes aleak in the seal. Most outgassing andbubbling isn’t quite this severe.Usually, these gas bubbles staywithin the sealant bead, though

they do detract from appearance,and weaken the sealant bead. (SeeFigure 7.)

Backer rod ruptureRupture of closed cell backer rod canoccur in several ways. Roughmasonry surfaces often (and easily)cut open the surface skin and under-lying cells, allowing enclosed gasesto escape. Rupture also can becaused by equipment used to pack

the backer rod into the joints. Asmentioned earlier, closed cell rodshould not be compressed over 25percent of its diameter. Variation injoint width is so predominant thatover-compression occurs often; thistoo can cause rupture of the skin andunderlying cells.

Over-compression in packing thejoint requires heavier pressure inuse of the packing tool, which in-troduces more chance of rupture ofthe skin and underlying cells, at thepoint of contact of the tool. Themore over-compression, the morepoints of contact, therefore the morechance of rupture. Should the jointbe in a rough masonry wall, theproblem is compounded. The roughsurfaces also will tear open thebacker rod when it is subjected tosuch over-compression.

This problem can be com-pounded further if heat is involved,and rapid expansion of the buildingpanels occurs. The more rapid clo-sure of the joints (and expansion ofthe gases) due to heat forces gasesinto the uncured sealant faster, onlyadding to the troubles.

Another cause of outgassing withclosed cell rod is sharp bends.Again, the surface skin and underly-ing cells can be ruptured. It is betterto break closed cell backer rod atsharp turns than to bend it. Thebreak provides an avenue of escapefor these gases, away from the seal-ant bead.

One proposed partial solution tothis outgassing problem was to packthe joint well in advance of (days be-fore) the caulking operation. How-ever, this would increase labor costssubstantially. The closed cell rodwould take a permanant set, par-tially releasing its grip to thesidewalls. This would risk move-ment during caulking (what’s more,it was found closed cell rod stillgassed, even after a year in a joint).

Outgassing is one problem thatdoes not exist with open cell rod. Thelack of an outer skin (or closedcells) totally eliminates any possi-bility of this occurring. In fact, pre-vention of outgassing was the pri-mary reason open cell backer rodwas developed.


Other consequences of heatClosed cell backer rod is a thermo-plastic olefin material. This charac-teristic limits its usage if highertemperatures are encountered. (Themaximum allowable temperaturerecommended by manufacturers is160°F.) Open cell backer rod is athermosetting plastic material withmuch higher heat resistance. It hasbeen used successfully for limitedperiods under hot-applied sealantmaterial (up to 500°F), with no ill ef-fects.

The effects of elevated tempera-tures on successful application of asatisfactory sealant bead are of vitalimportance. New construction inhot climates reportedly will en-counter temperatures of nearly300°F for some materials. A backerrod material installed under suchconditions must be able to with-stand these temperatures withouthaving a detrimental effect onapplied sealants. The possibility ofbacker rod outgassing or shrinkingbrought about by contact with hotsurfaces should be considered care-fully.

Both closed cell and open cell ma-terials have good cold temperaturecharacteristics under normal caulk-ing environments. However, in ex-tremely cold temperatures the opencell has a definite edge, remainingflexible at minus 60°F.

A minor role?

The backer rod in an expansion jointappears to play somewhat of aminor role. After the sealant has at-tained a full cure, the rod serves nofurther purpose other than, perhaps,offering some insulating propertiesin the expansion joints.

Although the role backer rodsplay may seem minor, it is impor-tant that architects, specificationwriters, caulking contractors andbuilding owners ensure that seals inexpansion joints perform well, anddo not become the prematurelyweak link in the structure.

It is in making possible that im-portant seal that the backer rod per-forms its hidden, but essentialtask.

ADVANTAGES (continued):

4. COMPETITIVE: DENVER FOAM® is competitively priced, throughout the World, with most backerrod materials

5. SEALANT ADHESION TO BOTH OPEN-CELL AND CLOSED-CELL BACKER ROD: Unbiased thirdparty laboratory tests and extensive field experience show that sealant materials usually adhere toboth open-cell polyurethane backer rod and closed-cell polyethylene backer rod. Performance ofboth type backer rod materials was found to be similar in that the behavior of the sealants wasessentially the same with each back-up. Sealants subjected to dynamic movement will not beadversely affected by adhesion to DENVER FOAM® due to the low surface strength and shearingcapabilities of the backer rod.

6. NON-STAINING: DENVER FOAM® is white to beige in color, odorless, and non-staining.

7. INERT: DENVER FOAM® is physically and chemically compatible with virtually every sealant.

8. COMPRESSIBLE: 25% nominal at 1 to 11⁄2 p.s.i. (70 to 100 gms./sq.cm) with an approximate densityof 4# to 6# per cubic foot (64Kg to 96 Kg per cubic meter).

9. FLEXIBILITY: DENVER FOAM® has been found to handle much easier than closed-cell polyethyl-ene due to it’s greater flexibility, resulting in faster application and usage, without size change, in awider range of joint width.

10. LESS INVENTORY INVESTMENT: Because each size of DENVER FOAM® can be used in such awide range of joint widths, the amount of dollar investment to carry a full inventory is greatly reduced.

11. LESS STORAGE SPACE REQUIREMENT: Due to compression packaging of DENVER FOAM®,considerably less storage space is required to carry an adequate inventory.

12. EASE OF JOB CLEAN-UP: Since DENVER FOAM® is packaged in easily-disposable polyethylenebags, the problem of container disposal is reduced to a minimum.

13. EASE OF SHIPMENT: Since DENVER FOAM® is packaged in compact, compressed, light-weightmaster bags, ease of hauling sufficient material to the job in a minimum of space is greatly facilitated.Also, emergency shipments of a substantial amount of backer rod can be made very easily by UnitedParcel Service or other small package carriers.

14 WIDE TEMPERATURE RANGE: DENVER FOAM® has been used successfully at temperatures of-70°F. (-57°C.) up to intermittent temperatures of 500°F. (260°C.). It has been determined by an in-dependent testing laboratory that DENVER FOAM® subjected to 300°F. (149°C.) for six weeks willstart to deteriorate, but since hot-pour sealants cool quite rapidly, DENVER FOAM® IS AN EXCELL-ENT HOT-POUR SEALANT BACKER ROD.

ADVANTAGES (continued):

15. NON-WICKING: DENVER FOAM® does not wick water, and is non-hygroscopic. DENVER FOAM®

does not absorb water readily under field conditions. If wetted during a rainstorm, the DENVERFOAM® is usually dry enough to caulk when the sidewalls of the joint are dry enough to apply thesealant. It is recommended that DENVER FOAM® should be reasonably clean, relatively dry, andfree of contamination at the time of caulking application.

16. FREIGHT SAVING ADVANTAGE: Since DENVER FOAM® is a highly resilient open-cell polyure-thane foam, it can be compressed substantially to increase the density (weight per cubic foot ormeter) enough to take advantage of the lowest available freight rate, thereby offering MAXIMUMFREIGHT SAVINGS without damaging the product.

The above picture clearly shows the two-stage compression packaging.

The Back Row contains 10 full sized Master Bags approximately 17" x 31" (43 cm x 79 cm) weighing about16 pounds (7.3 Kg.) each. The middle row contains 10 Master Bags semi-compressed and contained in areinforced paper sleeve of about one-half the original size. The compressed bale in the foreground contains10 semi-compressed sleeves further compressed to a size of approximately 18" x 21" x 36" (46 cm x 53 cmx 91 cm) having a total weight of approximately 175 pounds (79 Kg.), and a resultant density ofapproximately 22 pounds per cubic foot (357 Kg. per cubic meter). Upon releasing the restrainingpackaging, the DENVER FOAM® rapidly returns to it’s original size without any detrimental effect to thematerial. EXTREME CAUTION SHOULD BE USED WHEN CUTTING STEEL RETAINING BANDS.

NOTE: The compressed bale in the foreground may contain all the same diameter, or mixed diameters ofMaster Bags including Master Bags of MINI-BAGS as indicated on back page.

Trade Name - DENVER FOAM®

Prescribed Tests - ASTM D 5249 – 95U.S. Dept. of Commerce National Institute of Standards

Description - Denver Foam® is a backer rod serving as a backing for elastomeric,hot applied and other applied caulking sealants. Denver Foam®

controls the depth and amount of sealant required.

Specific Uses - For use in expansion/construction joints in concrete and pre-castconcrete walls, floors, partitions bridge construction, parking decks,curtain walls, glazing, log home construction, highway construction,and pavement maintenance.

Recommendation - WIDE TEMPERATURE RANGE: Denver Foam® can be usedsuccessfully at temperatures of -70° (-57°C) up to intermittenttemperatures of 500°F (260°C). Denver Foam® is an excellent hotpour sealant backer rod. Tested under ASTM 5249-95 at +500°F,Denver Foam® showed no signs of deterioration and actuallyexpanded in the joint. Cross linked (hot type) backer rods shrink andbreak down at approximately 180°F.

Denver Foam® is chemically inert and will resist oil, gasoline, jet fueland most solvents. Material is odorless and will not stain. The opencell construction eliminates the out-gassing problems associated withclosed cell cross linked (hot type) backer rods. Denver Foam® is100% non out-gassing.

Easy installation: Denver Foam® can be compressed as much as 80%of its original diameter. This allows the applicator to use fewer sizesin varying and/or twisting joint widths.

HIDDEN DANGER

There exists today many high occupancy buildings which claim to meet fire codesthat actually may have some very serious �Hidden Dangers.� These hidden dangers are inthe expansion/construction joints. The fire stopping material used in these joints are almostalways covered over with some type of sealant.

The expansion/construction joints do exactly as the name infers, they open andclose as a result of temperature changes. These changes occur generally once a day.Warmer temperatures close the joint and cooler temperatures open them. To have aneffective joint packing material it must be capable of moving within the joint, and remainin place.

There are three well-known fire blocking backup materials used in expansion/construction joints. Ceramic fibers, mineral wool and Ultra Block®. All three are capableof blocking fires in fire rated joints when they are installed with standard constructionsealants. However, only when they are initially installed.

To be an effective fire blocking joint packing material the product must remain inand completely seal the entire joint for a great number of years.

The structural or movement testing of Ultra Block® was done by HauserLaboratories in Boulder, Colorado. The results were impressive. The test was run on a±50% joint movement. The tests were run on all three products: ceramic fiber, mineralwool and Ultra Block®. Both the ceramic fiber and the mineral wool failed in less than 600cycles or 1.6 years. Ultra Block® tested for 28,000 cycles without failure, which represents76 years of service. There was no physical change in the Ultra Block® at the end of thetest. When mineral wool and ceramic fibers are subjected to cycling at a ±50%, they fail.When the joint closes the joint packing compresses, when the joint opens mineral wool andceramic fibers do not recover. The ceramic fiber and the mineral wool actually fell out ofthe test apparatus. The Ultra Block® retained its resiliency and looked exactly the same asit did before it was tested.

Unfortunately, in the past, on a number of occasions, the packing materials used inperimeter joints, had already fallen out of the joint when there happened to be a fire. Inmany instances human lives were lost. The �HIDDEN DANGER� was exposed.

Ultra Block® would not have let this happen, as it would have still had the jointsealed from fire. Do not let this �HIDDEN DANGER� cost more lives.

1. PRODUCT NAME

ULTRA BLOCK®

Mechanical Expansion and Construction Joint fire stopping System: 2-Hour, 3-Hour,

4-Hour Fire Rated

2. MANUFACTURER




ULTRA BLOCK® is a pre-engi-neered, patented, flexible textilefiberglass roll material with a fiber-glass matt facing, containingapproximately 30% by weight unex-panded vermiculite.

Specific Uses: ULTRA BLOCK®,when used together with anapproved sealant, provides a 2-Hour, 3-Hour, or 4-Hour fire ratedjoint system as designated bydesign configuration, which is capa-ble of withstanding ± 50% expan-sion and contraction. Most sealantmanufacturers in the United Stateshave tested one or more of theirsealants in a UL® classified ULTRABLOCK® system ranging in joint sizefrom 1⁄2" up to 7". Approved sealantmanufacturers include:

• Dow Corning• General Electric• Tremco Vulkem• C R Lawrence• Lymtal• Pecora• Quaker• Sika• Sonneborn• Specified Technologies Inc• Nelson

4. Benefits

Resiliency: To be an effectivefire blocking joint packing system, aproduct must remain highly resilientand must completely fill the movingjoint for a great number of years. Inmost packed and caulked joints,examination of the resiliency of theforming material is difficult to check,as the material is covered up withsealant. Many joint packing materi-als, such as mineral wood andceramic fiber, are not designed tohandle joint movement and may fallout or slump in the joint when sub-jected to continuous joint expansionand contraction. Under fire situa-tions, the fire blocking materialmust be in the same condition aswhen it was installed, meaning thatthe material must completely fill thevoid in order to block a fire. ULTRABLOCK® has a unique patented,hinged design and composition thatremains highly resilient under themost extreme conditions.

Structurally Rested: The struc-tural testing of ULTRA BLOCK® wasperformed by Hauser Laboratories.The test was run on a ± 50% jointmovement. Mineral wool andceramic fiber joint packing materialswere also tested. The joints werepacked in the fully open positionand were under the 25% joint sidecompression. The test ran continu-ously until either failure occurred orthe test was terminated. Failure ofboth the mineral wool and ceramicfiber materials occurred in under600 cycles, or 1.6 years. The ULTRABLOCK® successfully performed forover 28,000 cycles without failure orloss of resiliency, representing 76years of service at one cycle perday!

Fire Stopping: ULTRA BLOCK®

has been proven to withstand thetest of time in joint expansion andcontraction. The ULTRA BLOCK®

system also has a very unique fea-ture not present in either mineralwool or ceramic fiber material.ULTRA BLOCK® contains vermicu-lite, which expands when exposedto heat. As the vermiculite expandsit produces thousands of reflectiveshields that reflect heat back awayfrom the expansion joint. Whenexposed to fire on the caulked anduncaulked side there is no passageof destructive heat to the sealantbead on the opposite side.

ULTRA BLOCK® is a fire block-ing material in the fire rated jointsthat will be in place if and whenneeded. It is the only fire rated jointsystem today, which gives this pro-tection using standard constructionsealants! In addition, it does notrequire metal cover plates as somesystems do.

Composition and Materials: AllULTRA BLOCK® systems are manu-factured in accordance with projectrequirements. ULTRA BLOCK® ismanufactured in various widths andthicknesses, depending on the jointwidth, and sold in rolls.

5. EASY INSTALLATION

ULTRA BLOCK® requires nocutting, fitting, or fabrication.Simply open the bag, unwind theroll, fold in half with the matt sidefacing outward, compress and slideit in the joint to required depth.Apply sealant per manufacturersinstructions.

When joining ends of rolls, cuteach end at a 45° angle, alternatingcuts so that the folded over ULTRABLOCK® forms an interlocking v-shape. (See drawing below.)

SPLICING

6. TECHNICAL INFORMATION

All ULTRA BLOCK® systemsare covered with a nominal sealant(see list of manufacturers). Systemdesigns can range from 1-Hour, 2-Hour, 3-Hour or 4-Hour fire ratingsand joint widths from 1⁄2" up to 7"wide.

ULTRA BLOCK® systems allowthe mechanical expansion/construc-tion joint to function and fulfill thepurpose it was designed for, MOVE-MENT.

Testing of ULTRA BLOCK® foruse in expansion/construction jointswas conducted at UnderwritersLaboratories®, Northbrook, Illinois.Tests were performed to the full-scale, 180 sf surface area, and eachjoint tested was 12 ft. long. Our test-ing also included the hose streamportion. The full scale testing earnedus classifications by UL® for use inhorizontal and vertical joints pluscompliance with all major codes inthe United States.

Seismic testing of ULTRABLOCK® systems was performed bythe University of California-SanDiego. The seismic ”earthquake“simulation test was a joint projectbetween the US and Japan. ULTRABLOCK® performed perfectly underthe most severe conditions.

Respiratory Protection: When over PEL/TLV wear an approved face mask such as 3M 8210, N95 or equivalent, toprevent against inhalable glass wool fibers. Concentrations of fibers that exceed the recommendations of the maskmanufacturer will need a higher level of respiratory protection, such as a half mask respirator with appropriate dustfilters.



Eye Protection: Wear safety glasses with side shields, goggles or face shield when handling, installing or fabricatingto protect eyes against dust and fibers.

Skin Protection (clothing): Long-sleeved, loose fitting clothes and head covering are recommended. Wash workclothes separately from other clothing, towels and linens to prevent fiber migration. Rinse washer thoroughly.

Description - ULTRA BLOCK® is a heat expandable fire stopping material. Product is a 3 lb.density textile fiberglass blanket containing 32% by weight unexpandedvermiculite. All systems are designed to serve as the fire protection in allhorizontal and vertical mechanical, expansion/construction joints. ULTRABLOCK®’s resiliency under compression allows expansion joints to move andcompensate for the ongoing everyday expansion and contraction whileremaining in place to perform to its fire rated design function, if and whenneeded.

Recommendation - ULTRA BLOCK® is to be installed in fire rated structures. Joint must be cleanand dry. Sealant selection is based on joint location and must have adhesionand cohesion capabilities to contain the smoke and toxic fumes created byfire. Manufacturer will furnish (at no charge) system design drawings forcontractor to present to Code authority.

INSTALLATION INSTRUCTIONS

ULTRA BLOCK(R)

IMPORTANT! READ THE FOLLOWINGCAREFULLY BEFORE PROCEEDING

1. Select the ULTRA BLOCK(R) bag containing the proper width and thickness for the joints tobe packed and caulked.

2. Remove roll of ULTRA BLOCK(R) from the package. The end of each roll is glued slightly toprevent unwinding during transit. Pull this glued end loose and the ULTRA BLOCK(R) is ready forinstallation.

3. Referring to the installation diagrams, make sure the printed side of the ULTRA BLOCK(R) isagainst the surface to be packed. The groove in the ULTRA BLOCK(R) is to be positioned directlyover the center of the expansion joint. This is shown in the diagram in Step 1 of Configurations 1-2and assures proper folding so both edges of the ULTRA BLOCK(R) match to give the propercaulking surface. This is shown in Step 3 of Configurations 1 and 2.

Should the groove not be exactly in the middle of the expansion joint when it is insertedresulting in an uneven edge match up, the ULTRA BLOCK(R) can be easily pulled out andreinserted properly.

4. Multi-Layer Designs

Follow installation as outlined above. However, “Multi-Layer” Designs are seated under handcompression. Align pad edges, finish closing, compress and seat. Make sure pad surfaces on side tobe caulked are smooth. Flat faced wood trowel may be used to seat ULTRA BLOCK(R) to caulkingdepth.

In cases where wider ULTRA BLOCK(R) is used it may be necessary during packing of thejoint to put some tension on the ULTRA BLOCK(R) to remove any folds that may develop. Thistension need not be much but sufficient to eliminate such folds.

Splicing of two pieces of ULTRA BLOCK(R) together in an expansion joint is easilyaccomplished by cutting material in flat position. Using 45 degree angles and overlapping as shown,assures a tight fit with no voids or gaps.
