ROCKWOOL HARDROCK® Multi-Fix Angle Fillet
Stone wool angle fillet for flat roof applications The area between horizontal and vertical interfaces can sometimes be the most challenging part of a flat roof to insulate and seal. HARDROCK® Multi-fix Angle Fillets have been specifically designed to create a smooth transition at 90° abutments, for effective flat roof insulation and waterproofing.
Manufactured from high density, fire resilient ROCKWOOL insulation, and faced with a white mineral coated glass fibre fleece, HARDROCK® Multi-fix Angle Fillets are designed to fully support bituminous waterproof membranes at 90° abutments. The smooth transitions allow water to run off freely, as opposed to holding in corners, where it could potentially seep into the building and cause structural damage.
