Roof systems manufacturer, Marley has launched a new roof fire barrier to help prevent the spread of fire between adjoining properties, allowing specifiers to add an additional safety layer to roofing projects to keep both people and properties protected.
Marley Roof Defence will help specifiers select fire mitigation measures with confidence as the system delivers full protection to prevent the spread of fire from one roof to the next. Achieving up to a 60-minute fire rating, it can also be specified as a comprehensive fire barrier in larger roofs, or as a fire break in expansive buildings with large footprints such as apartment blocks, schools, care homes, offices, and hospitals.
The easy to install system comprises a double intumescent seal, with an inverted T design, that can simply be installed under tiles and between roof battens to close all gaps in the event of fire. Furthermore, when specified as part of a full Marley roof system it comes with a 15-year guarantee, providing specifiers with assurance around its long-term performance capabilities.
Marley’s Roof Defence has outperformed all fire testing requirements and fills every void from the party wall to the bottom tile, meaning smoke and fire cannot pass through.
Roof Defence features two strips of intumescent material bonded at 90 degrees. When activated by heat, the inverted T intumescent seal expands, filling the space between roofing battens and sealing all gaps under the tiles, slates, and other roofing elements. Roof Defence is supplied on a compact roll for easy storage and handling and is available in 100mm width and 6.3 metre length.
