Understanding Cavity Wall Insulation: How EcoGrants4u 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 specialise in providing professional cavity wall insulation services under the ECO scheme in the United Kingdom.

Is Cavity Wall Insulation Suitable for My Home?

Determining whether your home is suitable for cavity wall insulation is essential. Generally, your home will be suitable if:

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).

However, certain situations may render your home unsuitable for cavity wall insulation, such as poor maintenance, evidence of rising or penetrating damp, dirty cavities, exposure to extreme weather conditions, or blocked guttering. Our registered installers will assess whether your home meets the necessary criteria for cavity wall insulation.

How is Cavity Wall Insulation Installed?

The installation process for cavity wall insulation is simple, quick (about two hours), and minimally invasive. The most common method involves drilling small holes into the mortar at regular intervals and injecting the insulation material into the cavity. The holes are then refilled once the insulation has been blown in. Alternatively, rigid insulation boards may be fitted into the wall cavities for new-build properties.

Which Material 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.
