eXCom (Expressed Panel Facade System) is a versatile, glass fibre-reinforced recycled wood fibre and magnesium cement based cladding.

Fabricated from a combination of recycled timber materials (50%), mineral fibres and the latest fire retardant chemicals, eXCom is a lightweight but exceptionally strong board that provides a solid substrate for applied decorative finishes. eXCom weighs up to 50% lighter than traditional compressed sheeting and has exceptional fire resistance.

eXCom is an external cladding system providing greater versatility for your project. eXCom can be used on a number of different construction types such as:

Commercial Industrial RetailEducational Residential

eXCom is ideal for any application where a distinctive panelled facade is required.

When compared to other external linings such as Compressed Fibre Cement, eXCom:

PTH57-160x35

For smooth cuts, use a circular saw.

eXCom can also be cut easily using a normal hand saw.

The edge of eXCom can be planed or smoothed with an electric planer, rasp or file, or conventional papers if sanding is required.

For making holes in the board, use a standard drill tip. Do not use hammer action.

eXCom comprises of Multiboard panels used in a specialised sub system that incorporates cold formed section steel top hat sections, horizontal backing strip and Multiboard butyl gasket tape 50mm BFT-3/25.

Joint Sealant and Board Adhesive. Class A polyurethane sealant should be installed with strict adherence to manufacturers installation instructions.

Multiboard butyl gasket tape 50mm BFT-3/25.

Apply the foam seal gasket to the primary 160mm top Hat.

The seal can be applied to the mounted top hat in-situ or horizontally before it is fixed to the purlins.

Ensure the seal is applied to the centre of the purpose designed seal channel on the primary 160mm top-hat.

When fastening eXCom use recommended Multiboard (SMF 30-8-C4) fasteners. Where fasteners are to be countersunk, the depth must be controlled by a gauge to restrict the fasteners head depth to no more than the face of the board.

Fasteners must have the appropriate level of durability for the intended use, particularly in areas subject to salt spray, such as coastal areas.

Adhesives must not be used to attach sheets to the frame.

As a guide to the classification please refer to the table below:

> 400m from ocean or from severe marine influence.

Severe marine influence and up to 400m from marine environment.

AS 3566 Class 3

AS 3566 Class 4 -Stainless Steel.

Fasteners must not be overdriven, as this can reduce the holding capacity of the sheet.

Recommended fasteners are to be placed no closer than 40mm from the edge of the eXCom Panels and no closer than 100mm from any corner.

Primary top hat - 160mm x 35mm x 1.0mm BMT.

Intermediate top hat - 50mm x 35mm x 1.15mm BMT.

Pre-painted horizontal backing strip - 10mm x 0.55mm BMT.

When the eXCom Expressed Panel Facade System is to be used, the following needs to be considered:

Wind LoadsInsulation / SarkingCoating SystemsControl JointsMaintenanceSubstrate StructurePanel Layout

The layout of primary and intermediatel top hats are to be as per design engineers specifications. Refer to the table below as a guide for wind load design.

Determine the panel layout then mark out the centre point of each top hat on the purlins.

Position the top hats according to the predetermined marked spacing's and ensure they are vertical (check with a spirit level).

Fix the top hats to the purlins using appropriate fasteners ensuring both legs are fixed to the purlin to minimise flexing of the top hat.

Screw Head must be flush with or approximately1mm below the Multiboardsheet surface

Fix the bottom row of expressed panels allowing a 15mm overlap of the recommended butyl gasket tape. Leave the top row of fasteners in the eXCom loose to facilitate the insertion of the backing strip to the board.

Panels to overlap seal minimum of 15mm

15 10

Use the backing strip to space the vertical joint of the successive eXCom sheet ensuring a uniform 10mm space between the eXCom sheets.

Prepare the backing strip for installation by applying an appropriate sealant to the bottom (9mm) edge of the backing strip or by applying the sealer to the top edge of the eXCom sheet.

Ensure that a bead of at least 8mm in diameter is applied.

Insert the backing strip behind the top of the board. Fasteners are left loose to allow for the insertion of the backing strip.

The backing strip joint has been designed to overlap whilst retaining a flush fit behind the board.

Backing strip joints must overlap the nearest top hat and be sealed with two beads of an appropriate sealant to ensure a water tight joint.

2 Beads of Sealant

Backing strip overlaps at the nearest top hat by at least 50mm

After the backing strip is in position, the top row of fasteners need to be tightened to draw the eXCom sheet and backing strip against the top hat, completing the seal.

When installing the next layer of eXCom, apply a bead of the appropriate sealant to the top of the backing strip and then rest a eXCom sheet on the purpose designed 3mm edge of the backing strip.

Position the eXCom sheet ensuring all joints are 10mm. Fasten the panel to the top hats using the recommended fasteners.

Continue with this installation process until all eXCom sheets are installed.

All counter-sunk fasteners, must be covered with a fine acrylic modified render (patch), such as Eurorender Fine patch.

Remove any rough edges from the screw holes using a scraper.

Fill the pre-drilled holes with the recommended Eurorender Fine Patch.

Two separate applications may be required to allow for any shrinkage in the patch ensuring any pinholes are filled and the screw heads are water tight.

Sand the Eurorender Fine Patch with fine sandpaper until the surface is flat and flush with the eXCom sheet.

All expressed joints can be filled with a flexible acrylic sealant to ensure water tightness in the system. The sealant can be applied directly on to the expanded recommended tape.
