MDF V313 – humidity resistant – lightweight

 

 

MDF V313 Umidax lightweight – humidity resistant


approx. 600 kg/m3 bulk density

 MDF V313 Umidax - feuchte resistent - Standard

Area of application

 

Damp-resistant lightweight MDF for general non-bearing use in humid environments.

 

Description

 

MDF with low density and with a hard, finely sanded surface and a well screw-mountable core, glued with MUF glue. The board is subject to only minimum expansion and swelling even with high humidity and is suitable for general, non-bearing applications in humid environments. MDF Umidax® L can be finished with paper, melamine, veneer, composite lay-ups and varnish. The boards are made of 100 % coniferous wood and do not have any coarse fibres on the surface. The boards are excellent to mill and emit low quantities of formaldehyde (class A).

 

Using the product

 

The boards must be used only according to use class 1 (restrictions for ambient temperature and humidity) and hazard classes 1 and 2, EN 335-3. The boards must not have direct contact with water during and especially after installation. Any stacking must be done quickly on a pallet or with a sufficient number of crossbeams. Boards must not be stored upright unless floor contact can be ruled out. With fluctuating humidity conditions, the boards expand or shrink; however, to a lesser extent than S-Lux MDFs. A margin for expansion must therefore always be provided for. Use suitable tools for sawing, milling and drilling. MDF Umidax® L can be used for walls and interior decoration. A corrosion resistant metal fitting, e.g. galvanized steel, must be used in use class 2. Nails or screws must have a distance of at least 8 mm to the edge of the board.

UMIDAX® L MDFs meet the defaults of EN 622-5, option 1, cycle test, whereby the boards are immersed in water, frozen and finally dried. This cycle is repeated three times. After that, the test items are tested for swelling and transverse tensile strength. The boards are checked by our own laboratory daily and have the EU label.
