Insulation Technical Documents

Cavity Wall insulation is for properties with external walls that are made up of two layers of brick with a gap (or cavity) between them. The cavity is expertly filled with the recommended insulating material, keeping in around a third of the heat currently lost through the walls.

Loft insulation is easy to install and can immediately save 25% of the heat that is lost through an uninsulated roof. InstaGroup can install all-new insulation, or check your existing loft insulation to see if it needs topping up to the current recommended depth of minimum depth is 270mm.

External Wall (Solid Wall) insulation doesn't just warm up your home and save you up to £650 every year on heating bills - it can also give your property an attractive makeover. Solid wall properties are usually older buildings built before the 1920s, and are suitable for either our external or internal insulation systems. We can recommend the best solution to help keep in the heat, with all installations backed by a 25-year guarantee.
