Superglass Multi-Roll 44 is a high-quality, non-combustible glass mineral wool insulation roll designed to provide excellent thermal performance in loft spaces. It comes partially perforated, so you can easily use it between standard joist widths or lay it as a continuous full-width layer over the top of joists—reducing cutting, waste, and installation time.
This flexible roll format is particularly useful for both professional installers and DIY homeowners looking to improve the energy efficiency of new or existing homes.
Ideal for Loft and Cold Roof Applications
Superglass Multi-Roll 44 is specifically made for thermal insulation in lofts and cold pitched roofs. It can be installed between timber joists to insulate the ceiling of the space below or laid over joists to reduce heat loss through the roof structure.
Thanks to its user-friendly design, you’ll find it quick to fit, and the flexibility of the roll means it can adapt easily to most spaces without leaving gaps that can reduce thermal performance.
Reliable Thermal and Fire Safety Performance
This insulation roll provides a declared thermal conductivity of 0.044W/mK, helping to reduce energy bills by keeping more warmth inside the home during colder months.
When it comes to fire safety, Superglass Multi-Roll 44 is Euroclass A1-rated, meaning it’s non-combustible and meets the highest possible standard when tested to BS EN 13501-1:2018. It’s a reassuring choice for any residential or commercial insulation project.
Superglass Multi-Roll 44 also holds a CCPI (Code for Construction Product Information) assessment, with certificate number 005800129/0227, confirming its reliable, transparent performance data.
