Application

Suitable for use across all pitched cold and warm roofs to provide a secondary line of defence against wind-driven rain and snow.

Description

Protect VP400 PLUS LR is a highly-vapour-permeable roof underlay. It offers low vapour resistance, helping to avoid the risk of harmful condensation, whilst remaining completely airtight.

Features and benefits:

Highly-vapour-permeable, but completely airtight*.
Completely watertight with >7.0 m hydrostatic head of water resistance.
UV and heat resistant.
Tough and durable.
Has ‘unrestricted’ use for wind uplift in all exposure conditions in the UK and Ireland (zones 1-5 at 345 mm batten gauge), with a resistance to wind pressure of 1676 Pa, when tested to Annex A of BS 5534.
BM TRADA independently certified.
Helps to avoid condensation risk in the roof space in accordance with BS 5250 and NHBC requirements.
