Understanding Cavity Wall Insulation: How Get Eco LTD Enhance Your Home's Energy Efficiency
If your home was built after the 1930s, chances are its external walls are made of two ‘skins’ with a gap of around 50mm between them, making them ‘cavity walls’. Cavity wall insulation involves filling this gap with insulating material to prevent warmth from escaping to the outside.
At EcoGrants4u, a division of Tech Smart Group Limited, we specialize in providing professional cavity wall insulation services under the ECO scheme in the United Kingdom.

Is Cavity Wall Insulation Suitable for My Home?
- The external walls are unfilled cavity walls.
- The masonry and/or brickwork is in good condition.
- Your cavity is at least 35mm wide (or 50mm for some forms of insulation).

How is Cavity Wall Insulation Installed?
Which Material Installed?Should I Use?
Polystyrene beads are the most common material used in cavity wall insulation due to their effectiveness at keeping heat in and resistance to moisture absorption. At EcoGrants4u, we use polystyrene beads with a carbon coating for enhanced performance.
