Make your Castletownroche 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 continuous thermal barrier to keep warmth inside.

This barrier not only retains heat more effectively but also helps to minimise cold draughts, creating a more consistently comfortable and sealed living environment throughout the property.

For homeowners in Castletownroche, Premier Insulations is an SEAI-registered installer that provides this service locally, ensuring the work is completed to the highest standards for maximum efficiency.

Consequently, residents can enjoy a noticeably warmer, calmer home atmosphere while also benefiting from lower annual energy bills.

Is your home in Castletownroche suitable?

Our inspection of Castletownroche properties for cavity wall insulation begins with a thorough assessment of the cavity width to ensure it meets the minimum requirement for effective material filling. We meticulously check for any signs of existing moisture or dampness within the wall, as this must be rectified prior to any installation. The survey also includes a careful examination of existing wiring and pipework for potential obstructions. Finally, we evaluate the property's exposure to wind-driven rain to confirm its suitability and determine if any protective measures are necessary for a successful, long-lasting installation.

The two primary cavity wall insulation systems are blown mineral fibre and injected foam. Blown mineral fibre, such as glass or rock wool, is a non-combustible material ideal for most standard cavities, providing excellent thermal and acoustic performance. Alternatively, polyurethane foam is injected as a liquid that expands to fill the cavity, forming a highly effective air-tight seal particularly beneficial for properties with irregular wall constructions.
