DESCRIPTIONThe Cemintel Residential ExpressWall™ Facade System provides a versatile and durable facade with a modern style for residential buildings. Cemintel Residential ExpressWall™ is a highly adaptable system which can be used to conceal most common structural materials such as masonry, precast concrete, and steel or timber stud framing.

Residential ExpressPanel™ is an 8mm thick, autoclaved, cellulose fibre reinforced cement sheet which is purpose manufactured for use on residential building facades. It is a square edge sheet with a smooth flat surface suitable for painting.

The panels are supported by vertical top hat framing and fixed with concealed screws. The panels may be arranged in a variety of patterns, and surface relief is produced by expressed joint finishing.

Residential ExpressPanel™ can be finished with a wide variety of exterior grade acrylic paint or aggregate finishes resulting in a high degree of design freedom.

APPLICATIONSThe Residential ExpressWall™ System has been designed to be used for external cladding of buildings such as:

• Residential Homes.

• Duplex and Town House Developments.

It however remains the responsibility of the building designer to verify that the Cemintel Residential ExpressWall™ Facade System is suit able for the particular requirements of any given project.

The Cemintel Residential ExpressWall™ System has been designed as a drained cavity system (similar to traditional cavity brick systems), and is suitable for exposed applications.

Wind loadings are included for buildings within the scope of AS4055 Wind Loads for Housing, for wind classifications up to N6/C4.

The Cemintel Residential ExpressWall™ System can also be used as an exterior ceiling. Contact CSR Cemintel™ for details.

Note: Products marked with * are supplied by others.

FLASHINGS & CAPPINGS*Flashings are to be designed and installed in accordance with SAA-HB39 1997 and good building practice.

SARKING*A range of sarkings are available to suit various environments. Please cont act CSR Bradford for additional information.

AIR BARRIER*It is important to note that air barriers must be installed correctly as they are an integral element of a pressure equalised self-draining cavity system.

CSR Cemintel™ recommends DuPont Tyvek HomeWrap™ is installed and sealed in accordance with this guide and the manufacturer’s literature. (Suitable for up to 2kPa design wind pressure installations). It has a flammability index 3.

DuPont FlexWrap™ is used to seal the Tyvek air barrier at corners of openings, flashings and laps.


Recommended products are:

Air barrier: DuPont Tyvek HomeWrap™

Air barrier sealing: DuPont Flexwrap™

In these cases, the appropriate use of a building wrap as a vapour barrier or as thermal insulation, or both, can be effective in controlling condensation.

INSULATIONIt is recommended that insulation materials be installed to enhance thermal insulation properties and occupant comfort. Insulation also improves the acoustic performance of the wall against outside noise.

The level of insulation provided by a wall is determined by its R-value. Cemintel Residential ExpressWall™ systems incorporating Bradford R1.5 Gold Insulation can provide a thermal rating of R1.75. The higher the R-value the greater the insulation provided.

PANEL FINISHESResidential ExpressPanel™ has a natural finish on both faces, and the edges are painted dark grey. The exterior surface of the ExpressPanel™ must be coated with an appropriate finish.

Where panels are cut on site, the cut edges shall be sealed and coated with an exterior grade acrylic paint such as Dulux Weathershield X10™.

The exterior face of ExpressPanel™ can be finished with any of a wide variety of coatings, provided they are compatible with fibre cement, the ExpressWall™ screws and with the epoxy used to cover the countersunk heads. High build, exterior grade acrylic paint or aggregate finishes provide the best results.

A minimum dry film thickness of 250 microns is recommended to ensure adequate cover for the concealed fasteners.


DESIGN CONSIDERATIONSThis guide represents good practice, though it is not intended as an exhaustive statement of all relevant information. It remains the responsibility of the building designer to verify that the Cemintel ExpressWall™ system is suitable for the particular requirements of any given project.

AIR BARRIERIt is important to note that air barriers must be installed correctly as they are an integral element of a pressure equalised self-draining cavity system.

CSR Cemintel™ recommends DuPont Tyvek HomeWrap™ as an air barrier for design wind loads of up to 2kPa, provided it is installed and sealed in accordance with this guide and the manufacturer’s literature.

For installations exceeding 2kPa, a rigid air barrier must be installed to the project engineer’s specifications. Wind pressures over 2kPa occur in classifications N3 to N6 and C2 - C4.

Condensation control should also be considered. It is a complex problem, and can occur under a variety of conditions, not just cold conditions. Literature on this subject is available from CSIRO, BRANZ and ASHRAE and must be consulted when building in areas where condensation is likely to occur.

• Building wrap.

• Timber or Steel Studs (90mm min.) at 600mm maximum centres.

• 1 layer x 10mm GYPROCK™ plasterboard CD fixed to the inside of framing.

High gloss and low build finishes will require additional surface preparation to minimise fastener show-through. In all cases the coating manufacturer’s application instructions must be followed.

Exposed vertical gaskets should not be painted and Sikaflex™ Pro sealant may be painted if required.

Before applying finishes in C3 and C4 coastal areas (refer to definition), all panels must be thoroughly washed with fresh water to remove any salt residue. Refer to coating manufacturer for additional requirements.

The durability of the system can be increased by the additional treatment of steelwork, and by painting all exposed sealants to the sealant manufacturer’s recommendations. In corrosivity category C4, barriers to reduce the ingress of salt laden air are required.

CONTROL JOINTSControl joints in the Residential ExpressWall™ system are required to correspond to control joints in the supporting structure and anywhere that significant structural movement is expected.

A horizontal control joint is required beneath slabs to accommodate any expected deflection. The magnitude of the deflection must be verified by the building designer. Refer to FIG 27.

DURABILITYCemintel Residential ExpressPanel™ has many properties which make it a very durable product, including:

• Immune to permanent water damage in both short and long-term exposure.

• Will not rot, burn or corrode, and is unaffected by termites, air, steam, salt and sunlight.

• Not adversely affected over a temperature range of 0ºC to 95ºC.

The durabilit of the Residential ExpressWall™ system can be enhanced by periodic inspection and maintenance. Inspections should include examination of the coatings, flashings and seals. Paint finishes must be maintained in accordance with the manufacturer’s recommendations. Any cracked or damaged finish or seals which would allow water ingress, must be repaired immediately by recoating or resealing the effected area, or by removing the panel and replacing gaskets. Any damaged flashings, sheets or gaskets must be replaced as for new work.

The durability of the system can also be increased by the additional treatment of steelwork, and by painting all exposed sealants to the sealant manufacturer’s recommendations.


Table 1: Requirements for Corrosive Environments

Notes: • Sealed Joints: All horizontal and vertical joints must be completely filled with sealant. Refer to FIG 23 and 24. • Wash-down: • All walls must be sufficiently exposed from above so that rain can perform natural wash-down of the wall. OR • Walls which are protected by soffits above must be washed down twice per year, to remove salt and debris build-up, particularly at joints.

ExpressWall™ framing can also be fixed over masonry or concrete walls. All top hat connections must be designed by the project engineer.


STRUCTURAL SUPPORTResidential ExpressWall™ Top Hats and Intermediate Top Hats must be supported by a primary structural system.

The top hats can be fixed to appropriately designed timber or steel stud walls. The frames must be designed to support the top hats at the top and bottom of the wall, and at intermediate members within the span of the wall where required by the span tables. The connection of the intermediate member to the frame requires engineering design. Alternatively, horizontal members such as top hats may be installed across the studs at the required spacings as support for the ExpressWall™ Top Hats.

AS/NZS1170.0 Table C1 suggests that support framing be designed for a maximum deflection of span/250.

PRE-DRILLING HOLESHoles for screws must be pre-drilled. Use the recommended counter sinking tool for countersunk head screws, and a 6mm masonry bit for exposed head screws. Holes must be 6.2mm to 6.3mm in diameter. Do not use hammer action when drilling. Clean dust out of holes.

Note: Use only the recommended tool as supplied by CSR. The use of other tools for this purpose may reduce fixing capacity or reduce the weather resistance of the system. Refer to Components section for details.

HINT: One way of drilling holes is to drill the top sheet of a pack with the counter sinking drill set to approximately 12mm depth. This will give a starter hole on the sheet below, saving on set out time.

CORNER DRILLING TEMPLATEThe Cemintel Residential ExpressPanel™ Corner Drilling Template provides an easy method for locating the correct position for fixing holes at the corners of panels. The template locates on the corner of the sheet and the appropriate drilling position for the left or right corner of the panel is used to locate the drill bit.

PANEL INSTALLATIONResidential ExpressPanel™ must be in a dry condition when fixed. If panels become wet after installation, allow to dry before covering screw heads.

Panels must only be fixed using Cemintel Residential ExpressWall™ Screws.

Recommended panel installation procedure is:

1. Install Vertical Gaskets to Residential ExpressWall™ Top Hats.

2. Screw fix Residential ExpressPanel™ to top hats, leaving top edge screws out at this stage.

3. Install and adhesive fix Residential ExpressWall™ backing strip behind the top edge of the panel. (Alternatively, panels may be prepared with backing strip prior to installation. Refer to FIG 19 for details.)

4. Install remaining panel fixing screws.

5. Cover fastener heads.

CSR recommends the use of torque control screw guns.

If it is necessary to remove and replace a panel, avoid reusing screw holes in the top hats by adjusting fixing locations in the panel.

INSTALLING VERTICAL GASKET TOP HATInstall vertical gasket to central section of the Residential ExpressWall™ Top Hat for the full extent of panels. Be careful not to stretch the gasket when installing. When joining gasket, cut ends cleanly and push together before adhering.

When top hat is discontinuous, butt ends together tightly and continue gasket over the joint. If a gap is present, install a steel strip to support the gasket.

FIXING PANELS USING COUNTERSUNK HEAD FASTENERSDrive the countersunk head screw into the top hat using an electric screw gun. CSR recommends the use of a screw gun with torque control to prevent overdriving of screws.
