Introducing Safeshield: The UK’s Most Competitive Class A Fire Rated Membrane

Safeshield: The UK’s Most Competitive range of Class A Fire Rated Membranes, with additional Air, Vapour and Thermal Benefits.

As modern methods of construction and offsite construction techniques continue to evolve and improve, so do the expectations of clients; be it homeowners, tenants, or landlords. People expect to feel safe at home or at work, in a supermarket or at school. The dangers of fire within buildings are well documented, and the rate at which a fire can spread is at times frightening. Safeshield is a Class A Fire Rated Membrane; the first of its type for wall membranes in the UK.

Safeshield launched with our flagship XT Reflect membrane. Safeshield will provide a range of non-combustible products to sell into the timber frame, modular, offsite construction, cladding installers / system providers and main contractors.

Additional membranes and supporting products from Permavent will be launching in the coming months.

Why Safeshield?

Aside from being a superior fire performance membrane, Safeshield offers additional air and vapour permeability properties. It provides a W1 head of water resistance, which protects the timber structure of a building from the elements during construction. Its high UV resistance gives any construction added protection, and enhanced thermal performance offers value to clients by improving the thermal efficiency of the building; minimising the carbon footprint of a building in a day and age where our environmental impact is more important than ever before.

Is Safeshield Safe?

Safeshield has been vigorously tested and has been independently certified and fire tested for all applications. It is suitable for use in all types of construction where a fire rated product is required including high rise construction.

Safeshield has been manufactured to ISO 9001; 2008 and ISO 14001 standards.




Safeshielf XT Reflect Fire Safe A Rated Membrane

Permavent Safeshield XT Reflect is an extremely vapour permeable wall membrane with a low emissivity reflective surface and class A2-s1,d0 fire classification.

Safeshield XT Reflect is suitable for all walling applications and can be used safely in high rise and high risk buildings (e.g. schools, hospitals, care homes) to prevent the risk of fire spread.

Safeshield XT Reflect is also suitable for timberframe / modular off-site construction.

The unique composition of Safeshield XT Reflect resists the spread of fire across the cavity of the building.

Safeshield XT Reflect can be installed onto any substrate.
