Scope
Unsanded, moisture resistant board with extra hard surface for load-bearing applications in humid conditions.

Description
High-density chipboard with unsanded, hard surface and particularly screwable core, MUF glued. The board is subject to minimal expansion and swelling in conditions of high humidity. Suitable for load-bearing applications in humid conditions and also as concrete formwork board. The board is easy to saw and has low formaldehyde emission (E1 class). 

Use of the product
The board can be applied in service class 2 (restrictions in temperature and ambient humidity) and can be used in biological hazard classes 1 and 2 of EN 335-3. During and especially after installation the boards must, wherever possible, be optimally protected from any direct contact with water. They must be stacked flat, on a pallet or using a sufficient number of cross members. Boards should not be stored vertically, unless ground contact can be avoided. The board will expand/shrink under variable humidity conditions, albeit to a lesser extent than the Standard E1, meaning that an expansion space must be provided for at all times. Use suitable sawing, milling and drilling tools.
Durélis/Populair® can be used for structural floors (see Durélis Floor), walls, renovation and roof construction.
Durélis/Populair® can also be used for short-term concrete formwork (max. 2 days, absorbent formwork). For this last application a suitable dismantling oil must be used and the board can be reused several times. The concrete surface is smooth, after removing the formwork board no chip direction or deposit is visible. Betonspan is recommended for smooth concrete.

In service class 2, corrosion-resistant fittings must be used, e.g., galvanised steel. Nails or screws should be kept at least 8 mm away from the edge of the board.

Dimensions and stock range
Thickness: 8 to 28 mm. Width and length: 2440 - 2620 to 6300 length. Spano has high-capacity saws that support all sawing dimensions. In principle, all thicknesses and lengths/widths are available within the press capabilities. Contact our agent or mail to sales@spano.be.

(a) These values are characterized by a moisture content in the material corresponding to a relative humidity of 65% and a temperature of 20 °C. (b) The perforator values apply to boards with moisture contents H of 6,5 %. In the case of particleboards with different moisture content (in the range of 3 %  H  10 %) the perforator value shall be multiplied by a factor F which can be calculated from the following equation: F = - 0,133 H + 1,86 (c) Required for initial type testing other than for established products where initial type testing may also be done on the basis of existing data with EN 120 or ENV 717-1 testing, either from factory production control or from external inspection. (d) Experience has shown that to ensure compliance with these limits, the rolling average of the EN 120 values found from the internal factory production control over a period of ½ year should not exceed 6,5 mg HCHO/100 g panel mass.

The board meets the specifications of EN 312, P5, option 1, cyclic test, in which the board is immersed in water, frozen and finally dried. This cycle is repeated 3 times, after which the test specimens are tested for swelling and internal bond strength. The board is CE marked and checked daily by the in-house lab.
