Make your Castledermot home easier to heat

Cavity wall insulation significantly reduces heat loss in homes by filling the gap in external walls with an effective insulating material, which acts as a barrier to keep warmth inside.

This creates a more consistent internal temperature and results in fewer draughts, eliminating the cold spots often felt near exterior walls.

For homeowners in Castledermot, Premier Insulations is an SEAI-registered installer that provides this service locally, ensuring work is completed to the highest standard for both quality and grant eligibility.

Consequently, your household can enjoy a noticeably more comfortable living environment while also benefiting from lower energy bills.

Is your home in Castledermot suitable?

Inspecting Castledermot homes for cavity wall insulation begins with verifying a sufficient cavity width, typically at least 50mm, to accommodate the insulating material. A thorough moisture assessment is then conducted to ensure the cavity is free from dampness or existing water ingress, which could lead to problems post-installation. We also meticulously check for the presence of any old electrical wiring or services within the wall that could pose a hazard. Finally, the property's exposure to wind-driven rain is evaluated to confirm that the external walls are suitable and will remain durable after the insulation work is complete.

The two primary cavity wall insulation systems are blown mineral fibre and injected foam. Blown mineral fibre, such as glass or rock wool, is suitable for most standard cavities, offering excellent fire resistance and water repellence. Alternatively, polyurethane bead or foam systems provide a highly effective thermal barrier, often chosen for their ability to fill irregular cavities completely and their superior insulating properties.
