Danelaw Low Profile Dry Fix Valley Trough 3000mm

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.

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.

Tyvek Supro is the market-leading breather membrane, helping to protect roofs against wind and water, and also improve energy efficiency. Tyvek Supro is a durable, water resistant membrane that is reinforced with a laminated polypropylene nonwoven. This airtight, vapour-permeable membrane is extremely water-resistant, and can be used for all supported and unsupported pitched roofs. Tyvek Supro does not need any soffit, tile or ridge ventilation, which can save time and money in the construction process. In addition to warm, hybrid and cold roofs, applications include Scottish sarking board systems, low-pitched metal roofs, and wall and floor applications. Tyvek Supro Plus offers the same benefits, plus an integral adhesive lap tape designed for use in the Tyvek sealed roof system. Sealing all horizontal laps contributes to the system’s thermal efficiency by reducing air infiltration.

Tyvek® Housewrap Breather membranes are a highly water resistant, vapour permeable membrane sheets suitable for use as a secondary protective layer in timber and steel frames as well as concrete wall systems. They offer excellent protection against external weather conditions whilst remaining dry with its unique breathable properties.
