Multi-Roll 40


Superglass Multi-Roll 40 is a lightweight, non-combustible glass mineral wool insulation roll. The flexible roll is perforated to allow easy installation between common joist spacings and minimum onsite cutting and waste.


Superglass Multi-Roll 40 is primarily used as thermal insulation in new and existing lofts/cold roofs. However, it can be used in a number of other applications including suspended timber ground floors. When used in the loft/cold roof it can be installed between and over the joists.
