Thermaclass Cavity Wall 21 is an easy to install, polyisocyanurate (PIR) insulation board for full fill cavity wall applications, with excellent thermal performance (0.021 W/m.K). Featuring a low emissivity foil facing, it can be installed with up to a 10mm residual cavity (to support ease of installation and accommodate mortar squeeze) or as a full fill solution with no residual cavity. Another significant benefit of Thermaclass Cavity Wall 21 is that it does not require board joints to be taped, saving both time and additional cost to the installer. The tongue and groove edge profile helps to keep the boards in line and acts as the barrier to water ingress by preventing water from tracking between the board joints.
This Dupre Vermiculite loose-fill insulation is a highly absorbent protector suitable for packaging, chimney lining, loft insulation and high-temperature insulation. Made from aluminium-iron-magnesium silicates, it is a natural mineral used for void filling. This fill consists of thick flakes, making it ideal for containers of liquids where spillage and leaks may occur.
Knauf Insulation DriTherm 37 Cavity Slab measures 1.2m long, 45.5cm wide, and 5cm thick, covering 6.55m². An A1 non-combustible glass mineral wool, made with ECOSE Technology, designed for full-fill insulation in masonry cavity walls.
