Product Specifications

You can access our full library of product specifications here, which help to ensure product requirements for your projects are secured at the early stages of the development. Our product specifications have been purpose-written so there is no ambiguity in a product’s required performance, quality or material composition. We ensure our specifications are comprehensive and clear and include all relevant standards.

Construction membranes

Our high-performance range of construction membranes can help improve airtightness and the overall thermal efficiency of the building fabric. By reducing air leakage, the amount of heat loss from a building can also be reduced and we offer a comprehensive range of construction membranes to suit a variety of applications and project types.

Roofing underlays

Roof underlays are essential for virtually all tile and slate pitched roof constructions, helping to protect against wind-driven rain and snow and reduce wind uplift on the roof covering. We offer one of the broadest ranges of roofing underlays available to suit a multitude of application and ventilation requirements. All of our roofing underlays are watertight, offer excellent water resistance and some of the best wind uplift performance ratings on the market.
