Proctor FramePro W1 is a high-performance vapour permeable air barrier and wall underlay designed to provide a simplified and robust method of achieving low air leakage rates in modern construction projects. Manufactured by Proctor Group, this breathable membrane combines excellent vapour permeability with airtightness, helping to improve energy efficiency and narrow the performance gap between as-designed and actual energy performance.
Supplied in a convenient 1.5m x 50m roll, Proctor FramePro W1 is flexible and lightweight, allowing for easy installation while maintaining outstanding durability on site. Its resilient composition resists punctures and tears, reducing the likelihood of failures to meet designed airtightness targets, particularly when installed alongside Wraptite tape and other compatible sealing products.
