Internal air and vapour control product targets UK high-rise market
Glidevale Protect has launched a Class A2 fire rated internal air and vapour control layer for use in internal walls, ceilings, and floors.
According to Glidevale Protect, the new Protect FrameFoil FR membrane and complementary Protect FR Foil sealing tape are designed to be used alongside its existing FrameSafe FR external breather membranes.
The company stated that the new system provides a fire rated, airtight, and thermally efficient solution for both residential and commercial buildings, especially those over 11 metres in height and covered by the Building Safety Act in the United Kingdom.
Designed for use across construction types
Glidevale Protect explained that the Protect FrameFoil FR system is suitable for internal application in steel, masonry, and timber-framed buildings.
It added that the system has been independently fire tested both as a free-hanging membrane and in application over A1 and A2 substrates, achieving a Class A2-s1, d0 reaction to fire rating.
According to the company, this rating exceeds the requirements of Building Regulations Approved Document B in England and Technical Guidance Document B in Ireland.
Contributes to thermal performance and airtightness
The company stated that Protect FrameFoil FR features a woven glass fibre construction with an aluminium foil surface.
Glidevale Protect reported that the membrane delivers an aged thermal resistance (R-value) of 0.64 m²K/W when used facing into a still air cavity.
It said this helps enhance thermal efficiency and overall building energy performance.
Product aimed at compliance and offsite efficiency
Glidevale Protect highlighted that the system is intended for use across traditional and offsite construction methods.
John Mellor, Head of Marketing at Glidevale Protect, said: “FrameFoil FR is another exciting addition to our fire rated solution offering, designed to meet the increasing demands of regulatory compliance and building performance as well as helping to deliver airtightness, vapour control and thermal efficiency.”
He continued: “Combined with our Class A2 fire rated external wall membranes, we can provide specifiers, contractors, and developers with a fully independently fire tested wall membrane system solution.”
Mellor added: “This can be installed across all development heights, helping to build healthy solutions with fire rated materials that can provide added reassurance for specification.”
