Glidevale Protect Roofing Underlays

Roof underlays are required in virtually all tile and slate pitched roof construction and perform a number of key functions:

• Act as a secondary line of defence against wind-driven rain and snow.
• Reduce wind uplift on the roof covering.
• Are a temporary protection layer before the roof covering is applied.

Glidevale Protect’s range includes both vapour permeable and airtight membranes, air & vapour permeable (Type LR) as well as vapour impermeable (Type HR) underlays which can be specified depending on use, application and ventilation requirements.

All of the company’s roofing underlays are completely watertight with strong hydrostatic head of water resistance. They comply with all wind zone requirements and have some of the best wind uplift performance ratings on the market, enabling unrestricted use in the UK and Ireland without the need for additional sealing tapes to resist ’ballooning’ under wind load.
