What will happen to Builddeck Composites in hot and cold weather?
Builddeck Composites’ wood products constantly change in size as the UK’s weather changes. However, as long as the product is correctly installed to allow for expansion, the physical effects should go unnoticed.
Builddeck Composites’ wood plastic composites expand and contract along its length, so you may need an expansion gap. For example, allow a 30mm gap when fitting board’s length on/perpendicular to a solid structure i.e. a wall. As a general rule, for decking that is fitted in the UK there is potential for Builddeck Composites’ composite decking to expand by up to 0.5% of its length.
