Our non-breathable membranes are designed to provide a strong, dependable protective layer for traditional cold-roof systems and applications where ventilation is managed separately. These membranes act as an effective barrier against wind-driven rain, external moisture, and dust, helping to keep roof and wall structures dry, stable, and protected throughout the build. Manufactured for durability and long-term performance, they offer excellent tear resistance, reliable water holdout, and straightforward installation on site. Ideal for pitched roofs, timber frames, and cladding projects, they help maintain the integrity of the building envelope while supporting consistent performance in varying weather conditions. With a streamlined range focused on the most commonly used membrane grades and roll sizes, we offer simple, cost-effective options that deliver proven reliability. Whether you're working on a refurbishment or a new build, our non-breathable membranes provide a tough, practical solution for everyday construction and roofing work.
