What not to do when installing summit XPS insulation boards. These boards were installed incorrectly, there was no batons to support the boards, to stop them from bowing form the expansion & contraction. The MAX spacing for the “nail up” method is 700mm baton spacings, and when installing summit boards under purlin we use an H-Section to support the boards so that the boards don’t bow.
Summit XPS can be used for under Floor & Cavity Wall. Shera Fibre Cement Board09 July 2020 – Summit XPS Insulation boards safe for all applications!
