Cavity wall Insulation is one of the most effective Insulation Measures for Buildings in the UK.
There are a number of recognised systems to choose from. All systems are in any event, required to comply with current Building Regulations in accordance with the appropriate British Board of Agrement (BBA) Certificate for each product. . A system is only awarded BBA Certification after it has passed an ‘adequacy of fill’ test.

Home Energy Efficiency Ltd ® is currently approved to install the following systems/products, having been a recognised installer in the industry for 16 years.

Warmfill ® Bonded Bead – BBA 02/3938 – Premium Product

Cosytherm Whitewool – BBA 01/3789

Rockwool Energysaver – BBA 89/2316


The installation is carried out by our own fully-trained technicians who provide a professional, reliable and efficient service.

A series of small holes are drilled normally through the internal block work, adhering to the approved drilling pattern for the chosen system.

The injection process ensures that the whole of the cavity is fully filled.

The drilling pattern, coupled with the settings of the blowing machinery, ensure that the correct density of the product travels to all parts of the cavity.

After the installation is complete, the holes are carefully sealed and made good with mortar.
