Buy Good Quality high performance Cavity Wall Insulation with options of Mineral Wool, Aerogel, VIP panel cores at Wedge India. Cavity Wall Insulation is a method used to improve the thermal efficiency of buildings that have two layers (leaves) of wall with a gap (cavity) between them. It helps reduce heat loss, lowers energy bills, and increases indoor comfort.
Benefits of Cavity Wall Insulation
Reduces heat loss by up to 35%
Cuts energy bills
Improves indoor comfort
Reduces carbon footprint
Quick installation (usually 2–4 hours for an average home)
Cavity Wall Insulation using Wedge Perlite Boards offers a non-combustible, cost-effective, and moisture-resistant insulation solution, especially suited for fire-rated, eco-friendly, and long-life construction systems. These boards use expanded perlite as the insulating core, combined with cementitious or MgO-based binding materials.
