Make your Castlemartyr home easier to heat

Cavity wall insulation significantly reduces heat loss in homes by filling the gap between the inner and outer walls with a protective material, creating a powerful thermal barrier that keeps warmth inside.

This barrier not only retains heat more effectively but also helps to minimise cold draughts, leading to a more consistently comfortable and stable indoor temperature throughout the property.

For homeowners in Castlemartyr, Premier Insulations is an SEAI-registered installer that provides this essential service, ensuring all work meets the highest standards for quality and energy efficiency across the local area.

This upgrade ultimately fosters a sense of calm, comfortable living while delivering noticeably lower energy bills.

Is your home in Castlemartyr suitable?

Our inspection of your Castlemartyr property will determine its suitability for cavity wall insulation. We begin by verifying the cavity width is sufficient and uniform, as required for effective material filling. A crucial moisture assessment is then conducted to ensure the cavity is completely dry, preventing future damp issues. Finally, we check for any obstructions, such as debris or old wiring, and assess the property's exposure to wind-driven rain, which is vital for a durable and successful 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.
