Further BBA certificates for Knauf Insulation’s rainscreen range

The manufacturer says for the first time, contractors and specifiers can choose a certified solution for insulating rainscreen façades from a single insulation manufacturer, using Rocksilk RainScreen Slab for the outer leaf and OmniFit Slab 35 for the inner leaf.

Knauf Insulation has earned additional agrément certificates by the BBA for its rainscreen insulation product ranges, including what the manufacturer says is a market-first for applications using cross-laminated timber.

Knauf Insulation says Rocksilk RainScreen Slab now has the industry’s first and only agrément certificate by the BBA for use with cross laminated timber (CLT). In addition, OmniFit Slab 35 and OmniFit Roll 34 have been issued an agrément certificate by the BBA for use as insulation between the studs on timber and steel-frame conventional walls, in new and existing domestic and non-domestic buildings, with a masonry outer leaf, or in a ventilated rainscreen cladding system.

“We know how much specifiers and contractors value the peace of mind that comes from an agrément certificate,” said Luke Davies, Product Manager at Knauf Insulation. “Adding this application for use with CLT means our Rocksilk RainScreen Slab is certified for the most build-ups of any rainscreen solution on the market. For the first time, contractors and specifiers can choose a certified solution for insulating rainscreen façades from a single insulation manufacturer, using Rocksilk RainScreen Slab for the outer leaf and OmniFit Slab 35 for the inner leaf. This provides crucial assurance in a high-risk application.”

The manufacturer says Rocksilk RainScreen Slab (above) is a non-combustible rock mineral wool slab with Euroclass A1 reaction to fire classification, which means it complies with the strictest requirements of Approved Document B for dwellings over 18m tall. It is available in a wide range of thicknesses up to 250mm, with a thermal conductivity of 0.034W/mK. The OmniFit range of non-combustible glass mineral wool slabs and rolls also have Euroclass A1 reaction to fire classifications, making them equally suitable and compliant for dwellings over 18m tall. These products can all be used as part of a rainscreen façade system.

Knauf Insulations says Rocksilk RainScreen Slabs are also the first sheathing insulation products to carry the Code for Construction Product Information (CCPI) verification mark, providing greater confidence that the information given for these products is clear, accurate, accessible, unambiguous and up-to-date.
