Powerlon UltraBlock 300

Powerlon UltraBlock 300 is a thermo-reflective reinforced vapour control layer designed to maximise the energy efficiency of roof and wall installations. Its reflective surface helps improve the thermal performance of the building envelope, while the encapsulated foil or metallised barrier layer controls vapour movement to minimise interstitial condensation. The membrane is suited to environments where humidity levels are consistently high, giving exceptional water tightness alongside its vapour control function.
