Where can I use Loft Roll?

Loft Roll, as the name suggests; is primarily used to insulate the voids in between ceiling rafters within the roof space. A common practice with current building regulations is 2 layers, laid at 90 degrees to one another. Loft Rolls are also 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.
