Castellation cladding

Yes, Trex composite decking expands and contracts with temperature fluctuations, as with most composite materials. To account for this natural movement, it?s essential to leave a gap between boards during installation. The recommended gap is 5mm to 8mm for end-to-end board spacing and 3mm to 5mm between side edges of the boards. These gaps ensure that the decking can expand and contract without causing buckling or warping.
