A type LR pitched roofing underlay with good vapour permeability, for use in warm and cold roof constructions.
Suitable for use across all pitched cold and warm roofs to provide a secondary line of defence against wind-driven rain and snow.
Protect Zytec® is a high performance type LR roof underlay for use in warm and cold roof constructions. Its low vapour resistance helps to avoid the risk of harmful condensation whilst at the same time remaining completely airtight. Protect Zytec is both CE marked and BM TRADA certified. Where the highest performance of Protect VP400 Plus LR is not required but a heavier underlay than Protect VP300 is needed, Protect Zytec® meets the requirement.
