The proctor roofshield air & vapour barrier underlay delivers advanced protection for pitched roofing applications through its engineered three-layer breather membrane construction. Featuring nonwoven spunbonded polypropylene with a patented melt-blown core, this underlay creates a secondary barrier against rain, wind and snow penetration. The hydrophobically treated membrane provides low vapour resistance and air permeability, effectively preventing interstitial condensation while eliminating the need for additional vapour control layers. Water and uv resistant properties ensure long-term durability across demanding environmental conditions. Certified by iab and bba, this 50m x 1m roll reduces requirements for low and high level ventilation, streamlining installation in professional roofing projects. The innovative membrane structure maintains consistent moisture control throughout the roof assembly.
