MEDITE TRICOYA EXTREME Durable MDF is a groundbreaking construction material.

The panel exhibits outstanding durability and dimensional stability which allow them to be used in applications once limited to products such as concrete, plastics or metals. With the added benefits of light weight, sustainable raw materials and a guarantee of up to 50 years above ground and 25 years in ground, these groundbreaking panels provide architects, specifiers and designers with an entirely new construction material, allowing great design flexibility and endless opportunities for creativity.

The combination of acetylated wood fibre with the manufacturing technology of MEDITE MDF means it may now be used in situations and applications where normal MDF panels cannot. However, MEDITE TRICOYA EXTREME maintains all the design, fixing, machining flexibility of medium density fibreboards.

MEDITE TRICOYA EXTREME is a revolutionary wood based panel product, enabling its use in applications and environments that could not previously be contemplated. The raw material for the panel is modified to give outstanding dimensional stability and durability using a non-toxic environmentally compatible process.

Product Performance

Acetylation process

Many of the benefits observed in solid acetylated wood, including enhanced dimensional stability and durability and fungal resistance hold true for MEDITE TRICOYA EXTREME.

MEDITE TRICOYA EXTREME is also made using a high performance resin which is zero added formaldehyde, which makes the product not only exceed EU E1 but also CARB2 compliant.

BBA Assessment: As from June 2012 the British Board of Agrément has concluded that MEDITE TRICOYA EXTREME is satisfactory for internal and external use as a non-structural general wood based product. It is considered that this could form the basis of an assessment leading to the award of an Agrément Certificate after full commercial production is established. BBA Assessment number M2/49109.

The functionality and versatility of wood-based composite panels give them universal appeal. When properties such as high strength, light weight, good insulation, excellent machinability and ease in use are required, MEDITE MDF is the ideal choice for many applications.

FAQs

Yes. MTX Usage Guidelines and MTX Storage & Handling Guidelines are available on the website.

Moisture ingress behind a coating system can lead to small blisters or crystalline deposits appearing on the board. This can usually be identified by the appearance of ‘tide marks’ on the board. Should this occur the board can be successfully refurbished by the removal of the existing coating and re-application. Our guidelines for doing this can be found here.

MTX is guaranteed for 25 year in-ground and 50 year above ground. Please contact us for further information on this guarantee.

No. MTX is modified uniformly through the cross section, not just at the surface. As with all timber and wood-based panels processing can affect how the material will react in an environment. Best practice should be followed when processing.

Yes. Best practice must be followed when laminating to ensure the finished panel is balanced. As with all timber and wood-based panels lamination can affect how the material will react in an environment.

D4 class or equivalent adhesives must be used. Best practice and product guidelines must be followed.

Yes. MTX does not need a coating to maintain its durability and dimensional stability. Any coating applied to MTX should be of a high quality and to the coating manufacturers’ specification, and in accordance with the user guidelines. This is to prevent any water ingress in the panel to prevent damage of the coating (blisters…).

Thin MTX panels can be bent into a curve.

Most external and internal applications such as architectural façades, signage, doors and windows. It is the responsibility of the customer and/or end-user of MTX to ensure that the final use of the panel is checked by the appropriate authorities for conformity with local circumstances, building codes, regulations and standards and checked by an appropriately qualified engineer as required.

The requirements of the Building Decree 2012 in the Netherlands for fire mitigation is Euroclass D (or Euroclass B for height above 13m and other situations). This requirement applies to the finished cladding system and not for the raw individual components. MTX can therefore be used in this application provided it is finished (laminate, coating or paint) and end-users should ensure that the finished product complies with the requirements of the Building Decree. This requirement applies to all external applications including dormers, soffits…

Yes. MTX has a superior durability to traditional timbers used in pool areas.

No. MTX is moisture stable. As MTX is a wood-based panel it can absorb low levels of water. Moisture will not negatively impact board properties

Yes

The key difference between standard MDF and MEDITE TRICOYA EXTREME is that the raw material wood is acetylated. The acetylation process modifies the wood rendering it more dimensionally stable and, because it is no longer digestible, extremely durable.

Tungsten-carbide-tipped tooling is recommended for machining MTX.

MTX as a raw panel (sanded, unfinished panel) is rated Euroclass E (thickness ≥ 9.0mm)

Yes. We do not add any formaldehyde during the manufacturing of MTX.
