Marley Roof Defence is an intumescent roof fire barrier. It’s installed under tiles and between roofing battens to help prevent the spread of fire and smoke between adjoining properties in semi-detached and terraced houses.

Roof Defence provides full fire protection from one roof to the next, achieving up to a 60-minute fire rating, and can also be used as a fire barrier in large roofs, or as a fire break in buildings such as schools, care homes and hospitals.
