“We selected the glass block to create a visually stunning separation between the researchand clinical pavilions. It enabled the transmission of natural daylight into the labs andtreatment areas while still maintaining the appropriate degree of privacy. The use of glassblock greatly contributed to the Hillman Cancer Center’s artful expression of both thefunctional and emotional needs of the clinical pavilion dedicated to healing, and theopportunity for interaction and flexibility of a research pavilion dedicated to finding a cure.”~ Mihai Marcu, AIA, President, IKM Inc.

CIRCLE OF DESIGN EXCELLENCE AWARD WINNERSponsored by Pittsburgh Corning, this program recognizes those designs where glassblock forms a prominent architectural feature of a building, either interior or exterior.

Visibility/Light TransmissionGlass block provides exceptional visibilityin compliance with ADA guidelines forenclosed areas and has a dynamicrelationship with light, both natural andartificial. As light changes, so does thematerial’s appearance and in turn thesurrounding environment. It is also scratch-resistant and transmits up to 80% ofavailable light in both directions withoutany yellowing, clouding or weathering.

SecurityWhen top architects need to addsecurity to their projects, PittsburghCorning answers with a range ofsolutions:

Premiere SeriesAvailable in the widest range of sizes,shapes and patterns, these blocks offerenhanced resistance to impact, fire,sound transmission, graffiti and weather.

THICKSET® SeriesThese thicker-faced blocks offer all theperformance features of our PremiereSeries but with an extra reduction insound transmission and increased fireresistance available in 60- or 90-minuteratings.

VISTABRIK® Glass Block

Three inches of solid glass block makethis the top-performing product offeringthe highest ballistic ratings, resistance toimpact and sound transmission while stilltransmitting 80% of available light.

Impact and Ballistic ResistantPittsburgh Corning Glass Blocks are inherently stronger than conventionalglass because of the thickness of thefaces and the mortar that binds theblocks together. As a result the glassblocks are more difficult to break andtherefore provide resistance and are a deterrent to forced entry. Our solid 3"VISTABRIK® Glass Block resists penetra-tion from high-impact ballistics, including9mm and .357 magnum bullets.VISTABRIK® glass blocks are UL® testedand component recognized for ballisticlevels 1, 2, and 6.

Energy ConservationGlass block can provide more than double the thermal resistance (R-Value) of single-glaze 1/8" thick plate glass. The differences between the shading coefficient of glass block and flat sheetglass is also significant. Contributing tothis is the louvering effect of glass block’shorizontal mortar joints, which helps reduce light transmission from the highersummer sun. The size and orientation ofthe block can greatly affect the amount of shading that can occur.

Graffiti ResistantGlass block resists damage and is easy toclean.

“We started with the vertical elements of the garages – the elevatortowers – nd using the VUE® pattern, turned it into a virtual wayfindersystem. Then, we continued that theme with small wayfinder devices –information pylons using ESSEX® AA – throughout the garages.”– Graham Davidson, Architect

“This building had to embody the LAPD’s more open, community-oriented mission. TheARGUS® pattern glass block was really critical in creating that openness. It gives us theperfect balance of light and security.” ~ Clifton Allen, Architect

Earthquake ResistanceThe Northridge, CA earthquake onJanuary 17, 1994 was the largest earthquakein the United States to have its epicenterin an urban area. A detailed survey wasmade of the performance of structurescontaining Pittsburgh Corning glass blockpanel applications. In all sites visited, theglass block walls and panel systems thatwere designed and constructed inaccordance with Pittsburgh Corningspecifications and the provision of theUniform Building Code resisted theseismic forces without failure.

Noise ResistantThree inches of solid glass makes VISTABRIK®

a dense barrier to sounds from trains,traffic, crowds, sirens, and machinery witha 53 STC level. THICKSET® Series BlockSTC ranges between 48-50, and PremiereSeries Glass Block 35 to 40.

Sustainable DesignGlass block, made largely from sand andlimestone, is 100 percent recyclable, inert,low maintenance, and highly durable,lasting 50 years or more. Yet its dynamicrelationship with light gives architects theopportunity to create both aestheticallypleasing and energy efficient spaces.

PC® PANEL REINFORCING,PANEL ANCHORS & EXPANSION STRIPS

PC® Panel Reinforcing (top) — in panels — is embeddedhorizontally in the mortar jointsbetween every other course.

PC® Panel Anchors (middle) are used to tie Pittsburgh CorningGlass Block panels into the surrounding framework whenchannels are not used. PC® Expansion Strips (bottom), made of white polyethylene, are inserted at the head and jambs. The strips replace mortar at these locations to cushion the glassblock and allow the panel to expand and contract freely.

OTHER ACCESSORIES

Additional materials — such as mortar, channels or framing,packing, sealants and asphalt emulsion are available from other manufacturers.

PROVANTAGE® INSTALLATION SYSTEM

Unlike previous systems using sealant and spacers, the newProVantage® Installation System for use with Premiere Seriesglass blocks, can turn corners, make radius walls, build showersand is suitable for interior or exterior applications. The systemutilizes spacers to align and hold the blocks in place for easyassembly. Sealant is used to bond the spacer and blockstogether. The consistent, even-spaced joints are then finishedwith a special tile grout resulting in a clean, smooth professionallook. For smaller straight wall panels, with 3-side support,sealant can be used in the joints to provide an all-glass look.

PART 3 – EXECUTION3.01 PreparationA. Verify that (channels), (panel

anchors) have been provided athead and jambs for the purposeof providing panel support withinthe opening.

B. Mix all mortar components to aconsistency that is drier than

mortar for ordinary masonry. (See Section 1.05, Item 5).Retempering the mortar after ithas taken its initial set shall not bepermitted. Do not use antifreezecompounds or accelerators.

C. Freshly mixed mortar may createskin irritation. Avoid directcontact where possible and washexposed skin areas promptly withwater. If any mortar gets into theeyes, rinse immediately withwater and get prompt medicalattention.

3.02 InstallationA. Cover sill area with a heavy coat

of asphalt emulsion. Allowemulsion to cure at least 2 hoursbefore placing mortar.

B. Where panel anchors are used atjambs and heads in lieu of channelor chase surrounds, install panelanchors in the same joints (16inches o.c. maximum starting afterfirst course) where panelreinforcing will be laid. Panelanchors are to be embedded aminimum of 12 inches into themortar joints.

C. Place or adhere expansion stripsto jambs and head. Make certainexpansion strip extends to sill andcovers leg of panel anchor that isattached to jambs and head.

D. Set a full mortar bed joint, appliedto sill.

E. Set lower course of block. Maintaina uniform joint width of 1/4 to 3/8

inch plus or minus 1/8 inch. Allmortar joints must be full and notfurrowed. Steel tools must not beused to tap blocks into position.(Place a rubber crutch tip on end oftrowel to tap block into position.)Do not realign, tap or otherwisemove block after initial placement.For VISTABRIK® Solid Glass Blockunits, typical mortar joint is 3/8 inch.Special VISTABRIK® spacers thatprovide a 3/8 inch thick mortar jointare available.

F. Install panel reinforcing every 16 inches o.c. maximum (starting after the first course) in thehorizontal mortar joints. Runreinforcing continuously from endto end of panels. Lap reinforcingnot less than 6 inches whenever itis necessary to use more than onelength. NOTE: In corrosiveatmospheres (i.e. saline air,chlorine air, etc.), the use ofstainless steel channels,reinforcing and panel anchorsshould be considered. Consultlocal building codes in coastalareas. For VISTABRIK® Solid GlassBlock, use 15/8 inch widereinforcing (same as Thinline®

Series glass block). Do not bridgeexpansion joints with reinforcing.Install reinforcing as follows:• Place lower half of mortar in

bed joint. Do not furrow.• Press panel reinforcing into

place.• Cover panel reinforcing with

upper half of mortar bed andtrowel smooth. Do not furrow.

G. Place full mortar bed for joints not requiring panel reinforcing – do not furrow. Maintain uniformjoint width.

H. Set succeeding courses of block.Spaces at head of panel andjambs must remain free of mortarfor caulking with sealant.

I. Use only wooden or rubber tippedtools when tapping glass blocksinto place.

J. Strike joints smooth while mortaris still plastic and before final set.Remove surplus mortar from facesof glass blocks and wipe dry. (SeeSection 3.03). Tool joints smoothand concave before mortar takesfinal set. At this time, remove andclean out all excess mortar fromjambs, head and other locations.

K. After final mortar set(approximately 24 hours), installpacking tightly between glassblock panel and jamb and headlocations. Leave space for sealant.

L. Apply sealant evenly to the fulldepth of recesses as indicated onthe drawings and in accordancewith the manufacturers’ publishedapplication manual andinstructions.

M.All exterior glass block panelsshall be well sealed to preventwater entry.

3.03CleaningA. Remove surplus mortar from the

faces of the glass block at thetime joints are struck or tooled.Mortar should be removed whileit is still plastic using a clean, wetsponge or an ordinary householdscrub brush with stiff bristles.

B. Do not use harsh cleaners, acids (of any strength), abrasives oralkaline materials while cleaningglass block. Never use a wirebrush to remove mortar fromglass block surfaces.

C. Final mortar removal isaccomplished with a clean, wetsponge or cloth. Rinse sponge orcloth frequently in clean water toremove abrasive particles thatcould scratch glass surfaces.Allow any remaining film on theblock to dry to a powder.

D. After all sealants, caulking, etc.,have been applied, remove excesscaulking materials with commercialsolvents such as xylene, toluene,mineral spirits or naptha andfollow with normal wash and rinse.Be careful not to damage caulkingby overgenerous application ofstrong solvents.
