Please note:
The table above is the minimum quantity requirement. It is suggested that you add 10% to these figures to allow for waste associated with excluding naturally occurring defects and trimming boards to length, especially when creating patterned layouts.

Fixings relate to the approximate number of screws required per m2. If you need special components that are strength graded to meet Building Regulation requirements please consult your Q-Deck® retailer who will pass the enquiry onto Hoppings Softwood Products for consideration.
