Building regulations state that newly constructed homes need to be specified with fire protection to delay the spread of fire and allow crucial escape time.

The fire barrier is a critical part of fire protection when a roof is compartmentalised between adjoining homes.

Introducing the Marley Roof Defence fire barrier

  • A simple to install and fully fire protective solution that achieves a fire rating of up to 60 minutes. 
  • Two strips of intumescent material bonded at 90 degrees, with an inverted T design, are installed under tiles and between roof battens to close gaps. 
  • When activated by heat, the inverted T intumescent seal expands, filling the space between roofing battens and sealing all spaces under the tiles, slates and other roofing elements.
  • Marley’s Roof Defence satisfies all regulatory fire testing requirements and fills voids from the party wall to the bottom tile so smoke and fire cannot pass through.
  • Delivers proven protection against the potential spread of hidden roof fires and is a critical part of a guaranteed, single-source roofing specification, designed to provide long-term, safety-first performance and compliance with current regulations.
  • Marley Roof Defence is supplied on a roll. A separate intumescent ridge cap is also available to maintain the 60-minute fire barrier across the roof cavity.
