For cladding work, fit Standard Wonderboard on wooden battens pre-screwed to brick, concrete or other substrate. Remember that plastics tend to expand & contract with heat changes, so to avoid bowing or buckling never glue the sheeting across its whole area. Allow edge gaps for expansion and drill holes for screws and drive rivets at least 50% oversize.

Here at TW Plastics, we offer Wonderboard in White and in a choice of 3mm or 5mm thicknesses which are both available to be cut to size.
