The exacting thermal specification for NHS Lothian’s new Midlothian Community Hospital in Bonnyrigg includes EcoTherm polyisocyanurate (PIR) insulation roofboard.
EcoTherm Insulation UK says the bespoke 140mm thick Pitched-Roof thermal roofboard is providing “maximum insulation for minimum thickness” for the development’s 3,500m2 pitched roof. EcoTherm is being laid over rafters and above the waterproof membrane in an inverted warm roof construction. EcoTherm worked with insulation supplier Clyde Insulation Supplies and roof truss manufacturer – and the insulation installer – Ochil Timber Products, to provide a durable, thermally efficient insulation solution. Ed Anthony of Clyde Insulation Supplies said: “EcoTherm’s technical team supplied thermal calculations for various roof constructions considered during the design process. These assisted in specifying 140 mm Pitched-Roof board, offering a thermal resistance (‘R’ value) of 6.087 m2 K/W, as the best insulation option for the project’s thermal efficiency specification and pitched roof design.” EcoTherm Pitched-Roof insulation board has a lightweight, rigid PIR foam core with aluminium foil to both sides.
