Rockwool Building Roll is particularly suitable for metal-roof and industrial-building applications where thermal insulation and fire safety are important considerations. The fibrous structure of mineral wool helps reduce heat transfer while also contributing to acoustic performance. It can be incorporated into roofing assemblies in industrial sheds, warehouses, manufacturing facilities and other large buildings. Another roofing insulation option is XLPE Foam with aluminium foil. The closed-cell foam structure provides thermal insulation, while the aluminium foil facing provides a reflective surface that can be useful in roofing and building-envelope applications. TSW's documented XLPE range includes 6, 9, 13, 19 and 25 mm thicknesses, with one-side aluminium foil.
