Make your Castletown home easier to heat

Cavity wall insulation significantly reduces heat loss in homes by filling the gap between the outer and inner walls with a protective, insulating material.

This barrier not only retains valuable warmth but also helps to minimise cold draughts, creating a more consistent and comfortable indoor temperature throughout the year.

For homeowners in Castletown, Premier Insulations is an SEAI-registered installer, providing trusted cavity wall insulation services to the local area and its surrounds.

This upgrade ultimately fosters a sense of calm comfort within your home, alongside noticeably lower energy bills.

Is your home in Castletown suitable?

Inspecting Castletown homes for cavity wall insulation begins with a thorough assessment of several key factors. A borescope inspection is used to confirm the cavity width is uniform and suitable for material injection, while moisture probes check for any existing dampness that must be remediated first. We also carefully examine the inner leaf for the presence of old electrical wiring or other services that could pose a hazard. Finally, the property's exposure to wind-driven rain is evaluated to determine if it requires a rendered finish or specific insulation material to ensure long-term performance and protection.

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.
