Central Heating

Cavity Wall Insulation
The cavity is filled with an insulating blanket of mineral wool or expanded polystryrene bead to dramatically reduce the heat loss through the wall.

A tried and tested method
Cavity wall insulation has been around for forty years and its performance has been tried and tested over that period. A Government commissioned survey several years ago confirmed its effectiveness and the high level of customer satisfaction. You can be sure that Cavity Wall Insulation will continue to reduce your heating bills and give you maintenance-free service year after year.

For your peace of mind
BBA is an independent organisation dedicated to testing building materials and processes and approving them as suitable for purpose. All our materials are BBA approved and each of our Installers has been examined and issued with a BBA Installers card. As members of the Cavity Insulation Guarantee Agency (CIGA) we can offer an independent 25 year industry-backed guarantee to protect you from any problems, however unlikely they are to occur.

Survey
Before any work takes place a survey is carried out by one of our trained Surveyors. This service is free and entirely without obligation (click here to request a survey). At the survey, technical issues will be considered to ensure that your home is suitable for cavity wall insulation, and the process will be explained to you in full. Should you be liable to pay for a part of the cost, you will be told how much that will be. (No-one ever pays the whole amount! We can obtain a grant from an energy supplier to cover some or all of the cost of the work. Check out grants available).

Installation
The installation process is completed in less than half a day. Here is what you can expect to happen.

Drilling
Holes are drilled in the wall to a special pattern designed to ensure that all parts of the wall get an even and complete fill. The holes are 25mm in diameter and are normally driven through the mortar joints.

Filling
The mineral wool or polystyrene bead is blown pneumatically along a hose from the machine mounted in the van. When the area around the hole is full, the flow stops and the Installer turns off the nozzle. As each hole is finished in turn, a complete fill of the whole wall is ensured.

Finishing
Holes are filled with a matching mortar. Because the holes are small and drilled through the mortar joints, they are quite difficult to see on completion and the appearance of the wall is not impaired. With rendered properties, a matching paint or other finish is applied to blend in with the wall.

We're almost giving it away! Check out the grants available! You could be eligible for a grant from your energy supplier to cover part of the cost. In some cases, those on lower incomes could be entitled to free insulation.
