Description.
Xtratherm FR-MG is a mineral coated glass faced board. Xtratherm XT/FR MG boards should be laid over the vapour control layer in a break bonded pattern. The long edges of the boards should be laid at right angles to the direction of the substrate and all edges must be fully supported by the deck. The XT/FR MG insulation boards are secured by approved mechanical fixings or sufficiently bonded. The requirement for a separate water vapour control layer should be assessed in accordance with National Regulations.
