Cavity Wall Insulation |
 |
Cavity wall insulation, where possible, is one of the most cost-effective ways of insulating your house |
 |
Heat Loss from Your Home |
|
|
| Houses built in Ireland before 1980 have no insulation. |
Houses built after 1980 have some insulation but need upgrading |
Up to 50% of the heat loss from a house occurs through the walls. This can be reduced by 60% by insulating the walls. |
When considering wall insulation, first you should find out whether your home has cavity walls or solid walls. A building contractor or Insulation Contractor will advise you of that. |

Insulating cavity walls and solid walls |
|
In Ireland there are three types of home construction 1. Cavity Blocks walls 2. Solid Blocks walls 3. A two leaf cavity block wall that is two blocks on edge with a cavity in the middle usually between 100 mm and 150mm wide. |
1. and 2. Cavity Block and Solid Block construction can only be insulated on the outside or the inside at a cost of between 50 to 95 Euros per square Meter and a lot of disruption to the home. |
| 3. A two leaf cavity construction can be insulated by way of pumping a bonded bead into the cavity at a cost of between seven to ten Euros per meter depending on the width of the cavity. |
The cost of cavity wall insulation depends on a number of factors, including the width of the cavity, but it is typically in the region of €7 to €10 per square meter. For a typical semi-detached house, this gives a total cost of about €550-€950 With annual fuel savings of €200 to €320, the payback period will be in the region of 3 to 5 years. |
| You may be able to negotiate a lower price if you can persuade some of your neighbors to have their walls insulated at the same time. |
