Why Knauf Insulation flat roofs are tested to extremes

Fire, storms, gale-force winds. Mother Nature can be unpredictable, unexpected, and undeniably expensive — particularly when it comes to building damage. Knauf Insulation’s flat roof assemblies with FM Approvals give customers peace of mind.

Deep in the heart of the smallest state in North America is giant complex of laboratories where hurricane winds reach speeds of 280 km/h, explosive fires rage dangerously out of control and hailstones rain down in deadly blizzards.

The FM Approvals Natural Hazards Laboratory in the State of Rhode Island has a world-renown reputation for recreating the toughest weather conditions imaginable to punish roof systems and take them to their absolute limits.

Meanwhile, in the FM Approvals Fire Technology Laboratory, roof systems are set on fire and monitored to evaluate exactly how their building materials will respond in a worse case scenario.

In other words, the laboratories’ focus is dedicated to preventing potential threats turning into real life catastrophes.

This means that when flat roof assembles are independently certified by FM Approvals, customers know they have been exposed to some of the most demanding natural hazard and fire testing in the world. 


Outstanding FM Approval ratings

Knauf Insulation is proud that its commercial flat roof solutions have all been certified by FM Approvals and passed those demanding laboratory tests with distinction.

Our Group Market Manager and Head of Non-Residential, Magdalena Pyszkowski, says: “When customers invest in our commercial flat roof solutions they are investing in peace of mind.

“All our assemblies have achieved outstanding FM Approvals ratings including Class 1 for interior fire performance, Class A for exterior fire and the maximum uplift wind load ratings of Class 1-180.”

The results were achieved following research and development by Knauf Insulation’s quality teams and as today marks the start of World Quality Week the certification is a fitting tribute to their work.

“For investors in any commercial project it is vital that they have trust in the quality of the construction systems. Roof systems are the first line of defence in the complete building envelope and flat roofs are particularly sensitive to fire and wind load.”

Quality ensures customer trust

FM approvals

A total of seven Knauf Insulation assemblies have been certified by FM Approvals but as they can be adapted to meet any commercial roofing requirements, they offer a wide range of single ply, bitumen and Rock Mineral Wool possibilities.

The roof combinations are delivered as BIM files via the BIM Factory application.

“FM Approvals is a major step forward for Knauf Insulation. Certification instils confidence in our solutions. More and more companies, particularly American ones, are insisting on FM Approvals certification when it comes to their tendering process. At Knauf Insulation we are happy to help.

“Across the world we are seeing communities and their buildings being damaged by increasingly frequent and extreme weather events it is vital that our buildings are made as future-proof as possible. FM certification is a major step forward.”
