1) Under normal circumstances, the WPC profiles required during installation joist span 30-50 cm (depending on the size of the profile). 2) Since the power screw durability, to install the WPC profile of choice. 3) Using a dedicated installation screws must be pre-drilling. Pre-drill diameter should be less than straight nail or screw diameter of 3 / 4. 4) When the profile is greater than the width of 10mm, each end office should be two screws. TipsIn particular, the use of the environment or abnormal load conditions - such as hot water baths - installation may require a shorter distance.

Taking into account drainage, cleaning and minor thermal expansion, contraction and other reasons, the WPC installation profiles, side-to-edge, head-to-head must reserve the right gap between the Edge-to-side: The WPC profiles between the edge-to-side requests 4mm: When the weather is cold, when installed, clearance required 4mm. Head to head: WPC Profile head to head the size of gap between the profiles depends on the length of the installation of the temperature profile of the thermal expansion coefficient ( 0.9 10-4), as well as local potential maximum temperature.
