Glidevale Protect VP300
Application

It is 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. Can also be used as a temporary roof covering before the slates or tiles are applied.

Description

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 PlusLR is not required.


Features and benefits:

  • Vapour permeable with a performance better than required in BS 5250.
  • Completely water and airtight with >2.0 m water resistance.
  • Good all-round performance for its weight and one of the best in its class.
  • UV and heat resistant.
  • Tough and durable.
  • Can be used as a temporary roof covering.
  • BM TRADA Independently certified.
  • Helps to avoid condensation risk in accordance with BS 5250 and NHBC requirements.
