Proud Supplier of HOUSE RULES

House Rules on Channel Seven definitely saved the best till last, with Tricoya being the star of the show in the grand finale. Both finalists used Tricoya in outdoor applications, designing and building with a product made to withstand the harsh Australian conditions.

Aaron and Daniella built a tool shed from 18mm Tricoya and finished it in a black satin exterior paint. Tricoya provided the freedom to design and build a fully customised tool shed onsite, that will withstand exterior conditions.


Kate and Harry used Tricoya for their “Cabana” (Pergola) wall. Tricoya provides piece of mind for cladding applications with it’s 50 year warranty, and was easily machined and cut onsite, using ordinary tools.


Design Flexibility

The flexibility of Tricoya offers endless design opportunities so that it can be cut to size, machined, painted, wrapped, etc. without impacting on its unique properties.

Moisture Content

Tricoya is supplied with a moisture content of between 3 – 5%. An indicative measurement of the moisture content should be made before installation. If a measurement shows a moisture content of 8% or more, this may indicate the presence of ‘freewater’ and the Tricoya should be allowed to dry before processing, glueing or coating.

Design Freedom
All the design, fixing and machining flexibility of medium density fibreboards

Enhanced Stability
Swelling and shrinking dramatically reduced

Perfect for Coating
Improved stability and durability enhances service life of the coating. Damaged coating or core will not affect durability

Working with Tricoya

Tricoya can be cut, coated, sanded, glued, machined and fastened the same as any other high performing wood fibreboard – allowing users all the freedom normally associated with MDF but in extreme applications.


The panel may be cut, machined and used in exactly the same way as other MDF’s. The Tricoya panel is delivered with a 150 grit sanded finish and can be sanded with fine sandpaper to achieve a smooth finish.


Conventional water-based paint coatings may be used to decorate the panel.


Always install Tricoya with stainless steel fasteners & fixtures with A2 or A4 (EN 10088-1) quality or AISI type 304 or 316 when possible.


Superior to all other boards

Tricoya alleviates all the problems and limitations associated with using compact laminate and other composite panels.

Unlimited colour options

Unlike compact laminate, Tricoya can be painted or coated in any colour, making colour matching or selecting the perfect colour a breeze.

Fixing strength

Tricoya ensures fixing strength is not compromised and built to last. Competitor products such as composite panels, including compact laminate, often have issues with holding a screw, leading to loose, or even doors falling off hinges.

Reports and Certificates

Tricoya leads a new class of wood based panel products with Class 1 durability (EN 350-2) and exceptional dimensional stability, suitable for a wide range of exterior applications such as siding, façade paneling, trim, fascia’s, soffits, etc. Tricoya can be cut, machined and installed using techniques and equipment commonly used throughout the building industry and requires very low maintenance thereafter. The flexibility of Tricoya offers endless design opportunities so that it can be cut to size, machined, painted, wrapped etc. without impacting on its unique properties.

Tricoya has been independently tested by leading UK, European and Australian laboratories and has demonstrated superior dimensional stability and class 1durability, even in changing weather conditions, meaning it may now be used in situations and applications where normal MDF panels cannot.
