Flooring Installation Notes

The following notes highlight specific guidance from seven trust Wood:The use of outdoor wood flooring Wood Composite deck boards are subject to expansion and contraction when exposed to variations in temper ature.To accommodate for this potential thermal movement: Allow a 30mm expansion gap around the perimeter of the deck giving consideration to all walls, posts and other obstacles. Allow a 10mm expansion gap between the ends of boards To prevent'creep' secret fix each board with a single screw, positioned half way along its length, angled at 45 degrees and fixed through the bottom lip of the groove and into the joist or bearer below. in addition: • To aid water run off prepare the sub-frame to accommodate a fall of 2mm per metre along the length of the deck boards.wpc outdoor decking Fix joists/bearers at a maximum of 40cm centres when boards are fitted perpendicular to the joist direction.When boards are fitted diagonal to the direction of the joist/bearer provide supports at 30cm centres. • if the deck is to be raised or used for commercial use, seek guidance from a qualified engineer to ensure the structure is sufficient to carry the potential loadingPrior to laying: Preferably to be used on a hard sub-grade. in case of use directly on garden soil always place paving stones underneath the rails to create an extra strong foundation (see image 1).,wood plastic deck boards in that case level the ground first and remove possible weeds and use a black anti-weed membrane to prevent as much as possible weeds from growing. Keep a minimum gap of 30 mm between decking / rails and walls or other obstacles. in order to absorb the longitudinal effect of the WPC decking by influence of temperature changes, please keep an opening of about 10 mm between the crosscut faces in case of use of several sections of decking in the longitudinal direction of the terrace. Use a fine-toothed saw for cutting the material to size.
