Where can I use Loft Roll?

170mm Knauf Loft Roll, as the names suggests is primarily used to insulate the voids in between ceiling rafters within the roof space. The product is lightweight and easy to install. Simply roll out the insulation, cut to size and then place it between the joists of your loft. A common practice with current building regulations is 2 layers, laid at 90 degrees to one another. The product is also non-combustible and has an A+ rating for fire safety. 

170mm Loft Rolls can also be used to insulate in between separating floors within a dwelling to provide a heat loss solution from the room below. This also provides a basic level of sound insulation. Stud partition walls are often filled with this material to provide the same basic level of sound insulation.

Knauf Combi Cut Loft Roll 44 Rolls are 1140mm wide and perforated or cut to suit both 400 and 600 roof joist centres.
