Keep the heat in your home with our range of attic and wall insulation grants.

The benefits

Cheaper heating bills

On average, a home loses 20 – 30% of its heat through the walls which rises even further if they are not insulated. Up to 30% can be lost through a poorly insulated attic. Insulation will reduce heat loss and your heating bills.

More comfort

Our range of wall and attic insulation grants can help make your home more energy efficient and comfortable. A contractor registered with SEAI can help you to choose the best insulation type for your home.

Reduce your emissions

Reducing heat loss through your walls will reduce your energy consumption. As you will be using your heating less, you will also cut down on your greenhouse gas emissions.

Insulation types

Attic / Rafter insulation

Ceiling level roof insulation is generally the most cost effective of any energy efficiency upgrade made to a house. Even if you have some attic or rafter insulation you should upgrade it to today’s standard of 300mm of rockwool or equivalent.

Cavity wall insulation

A cavity wall consists of two rows of brick or concrete block with a cavity or space between them. Injection of insulating product from the outside is the best method for insulating this type of wall. This is a very cost effective method of wall insulation. If your home is built using solid wall or hollow block construction methods, cavity fill insulation is not possible. You have two options: either internal wall insulation or external wall insulation.

Internal wall insulation (Dry lining insulation)

Internal insulation is also known as dry lining insulation. This usually involves fixing composite insulation board containing insulation, a vapour barrier and plasterboard to the wall. The board is applied to the inside of the external walls.

External wall insulation

External insulation involves fixing insulating materials such as mineral wool or expanded polystyrene slabs to the outer surface of the wall. The insulation is then covered with a special render to provide weather resistance. A steel or fibreglass mesh is embedded to provide strength and impact resistance.
