An un-insulated or poorly insulated wall costs you money and harms the environment. On average, a home loses 20 - 30% of its heat through its walls and even more if they are not properly insulated.

The benefits of wall insulation:

• Reduction in heating bills
• Increased comfort levels
• Reduction in emissions

There are now grants available through the SEAI Better Energy Homes Scheme to help you improve the wall insulation in your home – see our latest news section for full details on the grants available.

Wall installation is not a DIY job for most people nor will the SEAI Grant scheme provide support to people completing DIY installations. 

Effectiveness of Insulation

The effectiveness of an insulating material is measured using a 'U-value'. A U-value is a measure of how much heat is conducted through a structure. Correctly installed insulation will have a low U-value as it will allow only small amounts of heat to pass through, thereby keeping your home warmer for longer. Homeowners availing of wall insulation grants under the SEAI Home Energy Savings scheme are required to install wall insulation which should achieve a U-value of 0.27 W/m K or better (i.e. Lower). All the insulation material we use will achieve the required U-value or best U-value that can be achieved for your circumstances.
