The Tricoya Extreme MDF from Gunnersen is a new range of high performance wood based panel products delivering excellent durability and dimensional stability in extremely challenging environments.
Suitable for exterior and interior applications, especially in wet and high moisture conditions, Tricoya ExDF uses proprietary acetylated wood technology and a modified fibreboard manufacturing process to create a robust and long-lasting wood panel product.
Tricoya ExDF challenges the most fundamental reason for wood swelling - water absorption onto hygroscopic wood fibres due to the presence of hydroxyl groups. The hydroxyl groups or water loving sites can bind or release water molecules causing wood to swell or shrink.
Tested in Australia for fungal decay and termite performance in comparison to durability class 1 timber in field trials at Humpty Doo, NT and the AFRC Lab, Melbourne, Tricoya ExDF’s performance is shown to significantly exceed durability class 1 timber such as Spotted Gum.
Tricoya ExDF panels are ideal for diverse applications such as façade cladding/siding; fascia/soffit panels; window and door components; door skins; wet interiors, including wall linings in swimming pools, bathrooms and changing rooms; speciality furniture including lockers, cubicles, chairs and tables; play frames, tree houses and exterior composite furniture; signage; automotive parts; and sound barriers among many more.
Tricoya ExDF is a highly versatile wood based panel that can be cut, coated, sanded, glued, machined and fastened, similar to any other high performing wood fibreboard, allowing users all the flexibility normally associated with MDF but in extreme applications.
The Tricoya ExDF 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. Tricoya ExDF should be installed with stainless steel fasteners and fixtures with A2 or A4 (EN 10088-1) quality or AISI type 304 or 316 when possible.
Tricoya ExDF is available in a standard board size of 1,220mm x 2,440mm in 6mm, 9mm, 12mm, 15mm and 18mm thicknesses. The 15mm and 18mm panels are also available in a large format size measuring 1,220mm x 3,050mm.
The sustainably sourced FSC certified wood based panels offer multiple advantages including design freedom with all the design, fixing and machining flexibility of medium density fibreboards; enhanced stability with reduced swelling and shrinking; fungal and pest resistance; and a 25-year in-ground and 50-year aboveground Tricoya ExDF warranty.
With extended periods between exterior coatings, Tricoya ExDF also reduces maintenance costs over the long-term. The wood based panels are also non-toxic and recyclable, and therefore, can be safely reused, recycled or incinerated.
