An AirGuard® vapour control layer can significantly reduce heat loss and increase energy efficiency. By controlling heat transfer and reflecting heat inside the building, they help keep buildings cool in summer, and warm in winter. AirGuard® AVCLs offer highly engineered vapour control, to help your project meet sustainable building requirements and achieve environmental goals. Using AirGuard® AVCLs for internal walls and insulating external walls with Tyvek® breather membranes creates a building envelope that is airtight and vapour-open. Together, they provide a holistic solution for optimum energy efficiency and interior comfort.

Roofshield is a unique, three - layer, nonwoven, spunbonded, polypropylene breather membrane with a patented melt - blown core. It is intended for use as a pitched roof underlay (breathable roofing felt) and is fixed beneath tiles and slates.

Tyvek® Supro Breather membranes are extremely durable, flexible membranes intended as a roofing underlay in pitched roof constructions. They have the ability to be used in all tiled or slated roofs whether they are refurbished or new build projects. This membrane actively resists wind, snow and dust from entering roofing construction by creating an air tight seal.
