Description
The 75mm Knauf Dritherm 37 Glass Mineral Wool Cavity Wall Insulation – 174.8m² (40 Packs) is a high-performance cavity wall insulation solution designed for use in external masonry cavity walls, particularly in extensions, renovations, and properties with narrower cavity widths. Manufactured from glass mineral wool, these insulation slabs provide effective thermal performance while helping reduce heat loss and improve overall building energy efficiency.
Knauf Dritherm 37 cavity slabs are designed to friction-fit within a 75mm wall cavity and can be easily cut to fit between standard wall-tie spacings. With a thermal conductivity of 0.037 W/mK and a thermal resistance of 2.00 m² K/W, these insulation slabs provide reliable thermal protection and can also be combined with other insulation systems to help achieve required U-values.
This bulk pack of 40 packs is ideal for large construction projects, new builds, and extensions requiring extensive cavity insulation coverage. Offering excellent fire performance with a Euroclass A1 reaction to fire rating, Knauf Dritherm 37 is BBA certified, EUCEB certified, and complies with BS EN 13162 standards for quality and durability.
