Fixation on a wooden lower structure
General
- The choice of the manner of fixation and the supporting structure is mainly determined by the nature of the base as well as the physical construction requirements. EUROTHANE G boards can be used as wall, ceiling and partition wall coatings. The boards are then attached to a wooden supporting structure.
- As a wall coating, EUROTHANE G insulation boards can also be bonded directly to the base using adhesive gypsum plaster.
- EUROTHANE G boards must be positioned about 1 cm from the finished floor to avoid the absorption of moisture by the plasterboard. If this is not possible and the boards must be positioned flush to the floor, the bottom edge of the board must be protected with a plastic foil or sealing kit.
Fixation to a wooden supporting structure
- The supporting structure must be sufficiently rigid. The maximum bend under the influence of the expected loads must be less than 1/300 of the spanning.
- Straight, dry wood must be used for this supporting structure (RNG 3rd quality NBN 272). The sides of the slats against which the EUROTHANE G boards will be positioned must be planed. The slats must not be treated with impregnation products that can damage the means of fixation or insulation by diffusion.

NOTE:
Fixation of the boards at the joints must always be done over a slat.
EUROTHANE G boards must be stored flat and dry.
- EUROTHANE G plates are stiffer along their length than in the transverse direction. The distance between the wooden slats can therefore be greater with a transverse positioning (650 mm) than with longitudinal positioning (600 mm).
- The fixation of EUROTHANE G boards to the supporting structure is preferably done with adapted trumpet head plasterboard screws. Up to a board thickness of 35 mm, adapted nails can also be used.
- Screwing has the advantage that the slats do not spring back, so that the risk of damaging the face of the board is minimal and fewer fixation points are needed.
- The distance between the screws and the long edge of the EUROTHANE G boards must be at least 10 mm. The distance to the crosscut or sawn edge must be at least 15 mm. The maximum distance between the screws is 250 mm (200 mm for nails).
- The screws or nails must always penetrate the board perpendicularly and in such a way that they are embedded into the plasterboard by a few tenths of a millimetre but without piercing the cardboard. The screws or nails must not protrude through the wood. Screws with a self-tapping point and trumpet head must be used. The length of the screws must be such that they penetrate into the wood by at least 20 mm.
