Why choose them
Three strengths that define the store
Loft insulation rolls
Insulation Superstore stocks mineral wool and glass wool loft rolls in a range of depths and thermal values. Rolls are supplied in trade packs for easy coverage, and many products can be cut to size — a convenient, economical choice for upgrading lofts to current U-value targets.
Rigid insulation boards
PIR and phenolic insulation boards provide high thermal performance in thin sections — ideal for floors, warm roofs and insulated plasterboard builds. The store offers multiple thicknesses, edge types and complementary adhesives and fixings for professional installation.
