Product Description

Vent 3® Classic is a breathable roof underlay that gives major benefits over traditional underlays.

The Cromar breather felt is made from two, high-tensile, spun-bonded polypropylene layers. This triple layer, high performance, breathable membrane is thermally calendared to a micro-porous polypropylene film.

  • Layer one - waterproof surface
  • Layer two - breathable waterproof membrane
  • Layer three - protection from abrasion and damage, giving additional strength

This products has exactly the same specifications as the Vent 3 Light breathable membrane, but the Classic has a heavier GSM at 115, compared to this Light's 95 GSM.

Benefits

  • Clean and easy to use
  • Lightweight and flexible
  • Waterproof membrane
  • High vapour permeability
  • Long-term durability and tensile/tear strength
  • High wind uplift resistance
  • BS 5534:2014 compliant

Application

Can be used in supported or unsupported roof systems, regardless of whether they are tile, slate or metal, and in warm and cold roof applications.
