Multi-Roll 44


Superglass Multi-Roll 44 is a non-combustible, glass mineral wool insulation roll. The roll is supplied partially perforated providing the flexibility to be used between common joists spacings and as uncut as a full width roll as layers over the joists, reducing the need for on-site cutting and waste.


Superglass Multi-Roll 44 is primarily used as thermal insulation between and over the timber joists of new and existing lofts/cold pitched roofs. However, it can be used in several other applications including suspended timber grounds floors.
