Poorly insulated walls contribute up to 30% of the total heat loss in a dwelling. Insulating the vast exposed wall area in the dwelling would reduce the output required from the heating appliance and thus save you money. Without insulation the heat simply passes through the wall and out into the atmosphere. This is one of the most cost effective improvements to carry out on your home.
Insulation boards are mechanically fixed to the inside of the external walls. A vapour control membrane is applied to prevent moisture damage to the property.
Objects including radiators, cupboards, skirting boards etc. must be removed from the walls before work commences. This disruption should be carefully considered when choosing the internal insulation method.
The pay back period for internal insulation is approximately 10 years, depending on existing heating costs and future savings.
Grant: A grant of €2500 is available for internal insulation projects.
Cavity Wall Insulation:
Cavity wall construction consists of two “skins” of solid block work separated by a void or cavity. Insulation boards are placed on the external side of the internal block work and a void is left between the insulation and the outer leaf of block work. This void is left to ensure that moisture cannot penetrate through the insulation and into the interior of the dwelling.
