A type LR pitched roofing underlay with good vapour permeability, for use in warm and cold roof constructions.

Jump to:
+44 (0)161 905 5700 Website

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 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.


Features and benefits:

  • Highly vapour permeable with a performance better than required in BS 5250.
  • Completely water and airtight with >2.0 mm water resistance.
  • UV and heat-resistant.
  • Does not generate nuisance noise under wind loading.
  • BM TRADA independently certified.
  • Helps to avoid condensation risk within the roofspace in accordance with BS 5250 and NHBC requirements.
  • Easy to cut and handle.
  • Achieves Zones 1-4 at 345 mm batten gauge (1519 Pa), when tested to Annex A of BS 5534, ensuring wide coverage across the UK and throughout Ireland
  • Achieves unrestricted use for wind uplift Zones 1-5 at 310 mm batten gauge (2188 Pa) or when installed on sarking board.
