ROCKWOOL® announces launch of new Fire Barrier EN

  • 15 May 2024

To help designers and specifiers improve building fire safety, stone wool insulation manufacturer ROCKWOOL® has launched a new fire barrier product that is tested in accordance with the latest BS EN standards.

Tested to meet BS EN 1364-1:2015, 50mm Fire Barrier EN is available with a black foil facing on one or both sides, for single- and double-layer systems respectively.

Will Wigfield, Product Manager HVAC & Fire Protection at ROCKWOOL, comments: “Fire Barrier EN will replace our existing fire barrier products.

“With the two options now available, we are underlining our commitment to ensuring that ROCKWOOL products are tested to EN standards wherever possible, while simplifying specification by streamlining the range.

“Customers will see that we have built upon and expanded the scope of application available from ROCKWOOL. Depending on the application and fixing method, Fire Barrier EN offers fire resistance of up to two hours.”


Fire Barrier EN has been tested in a series of common applications including below concrete soffits and within timber joist construction. Steel, copper and plastic pipes, as well as timber beams and cable trays were tested protected with a 300mm sleeve of Fire Barrier EN stitched-back on each side.

Fire Barrier EN launches on 15 May 2024 following the expiration of Fire Barrier and Fire Barrier Slab certifications on 1 May 2024. Specifications written prior to this date will remain valid, but ROCKWOOL recommends swapping specifications to Fire Barrier EN wherever possible to benefit from the latest EN testing.

Fire Barrier and Fire Barrier Slab will remain available to support ongoing projects until 15 November 2024, when they are formally discontinued.
