Eglinton

Make your Eglinton home easier to heat

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

This effective barrier not only retains heat but also minimises the infiltration of cold air, resulting in noticeably fewer draughts and a more consistent indoor temperature throughout the property.

For homeowners in Eglinton and the surrounding region, Premier Insulations is an SEAI-registered installer, ensuring that all work is completed to the highest standards and may qualify for available grant support.

Ultimately, this upgrade cultivates a sense of calm comfort while delivering lower energy bills for the household.

Is your home in Eglinton suitable?

Inspecting Eglinton homes for cavity wall insulation begins with a thorough assessment of several key factors. A borescope inspection is first used to confirm the cavity width is uniform and suitable for material injection. We then meticulously check for any signs of moisture penetration, pre-existing debris, and the presence of electrical wiring or other services within the wall. Finally, the property's exposure to wind-driven rain is evaluated to ensure the installation will be durable and effective for the long term.

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 suitable for most properties, effectively filling the cavity to reduce heat loss. Alternatively, insulating foam is injected as a liquid that expands to create a seamless thermal barrier, offering excellent resistance to air leakage in homes with consistently sized cavity walls.
