Cavity Wall Insulation

External Wall Insulations


A cost-effective solution to enhance the thermal efficiency of homes is the Cavity Wall Insulation. Most properties built from the 1920s onwards have cavity walls, and the insulation is inserted to fill the gap between the walls, making your home warmer and reducing your energy bills. The installation process is backed by a certified CIGA guarantee that assures you of the work’s quality for up to 25 years, giving you reassurance that professionals have completed the job correctly.
