A type LR pitched roofing underlay with good vapour permeability, for use in warm and cold roof constructions.
Suitable for all pitched roofs, particularly fully supported applications, to provide a secondary line of defence against wind-driven rain and snow, and reduce wind uplift loads on the roof covering.
Protect VP300 is a medium weight vapour permeable roof underlay with a vapour resistance better than that required by BS 5250. Protect VP300 is both CE marked and BM TRADA certified and provides an economic solution when the highest specification of roof underlay such as VP400 Plus LR is not required.
Features and benefits:
Embossed grey upper and grey/white lower surface. Printed with red product branding for ease of identification.
