Vapour permeable & air open underlay

Glidevale Protect manufactures an innovative air and vapour permeable roofing underlay which delivers ventilation into the roofspace via a hydrophobically treated, melt-blown technology core. This ensures an uninterrupted airflow rate and delivers the required permeability to eliminate the need for additional roof ventilation whilst allowing vapour to escape and controlling the risk of condensation. With no additional ventilation required, this saves time and labour on installation whilst helping to ensure a healthier building for occupants.
