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 product 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

- Waterproof membrane
- High vapour permeability
