Not all homes are suitable for cavity wall insulation, examples of these are houses built using hollow blocks (9” cavity blocks), solid walls with no cavity or stone finished properties. In the form of internal wall insulation also known as Dry Lining, or another option is External Wall Insulation. Up to 40% of heat can be lost through external walls.
Internal Wall Insulation (IWI) also known as Dry lining is fitted to the internal walls of your home. It is finished in a coat of plaster that is ready for you to add a coat of your favourite colour paint. There are SEAI grants available for this Internal Wall Insulation of up to €4,500 depending on property type.
Internal wall insulation involves the fixing of an insulated plasterboard slab to walls, attic and sloped areas of property. It can be used to upgrade existing or new build properties.
The plasterboards come in a wide variety of sizes and the thickness can be adjusted to provide levels of thermal performance required by the Irish Building Regulation or SEAI standards. This process involves internally fixing an insulated board on the external walls of the house. Usually the walls will have fixtures and fittings which are taken off and refitted. The walls are always left skimmed and ready for painting.
Benefits of internal wall insulation:
- Increased comfort in the home
- Adds value to your home by increasing your BER rating.
- External wall appearance is maintained during works.
- Cost-effective
- Reduced energy cost
