Composite decking can be glued down to a surface (and screwed), but it’s not necessary to do so. Our Ecoscape composite decking boards are installed in place using a hidden fixing system with locking clips which are screwed into the subframe.
At Ecoscape, we stock Hidden T-Clips, Locking Clips, and Start/Finish Clips that fasten the composite decking boards to the joists and subframe underneath.
