Application

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.


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 UKCA marked, 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:

  • Vapour permeable with a performance better than required in BS 5250.
  • Completely water and airtight with >2.0 m hydrostatic head of water resistance
  • Good all-round performance for its weight and one of the best in its class.
  • UV and heat resistant.
  • Tough and durable.
  • Achieves Zones 1-3 at 345 mm batten gauge (1179 Pa), when tested to Annex A of BS 5534, ensuring suitability in a large area of the UK and Ireland.
  • At 310 mm batten gauge VP300 achieves Zones 1-4 (1501 Pa) and up to 250 mm batten gauge - Zones 1-5 (2731 Pa)
  • BM TRADA independently certified.
  • Helps to avoid condensation risk in accordance with BS 5250 and NHBC requirements.
