Make your Dunmore home easier to heat

Cavity wall insulation significantly reduces heat loss by filling the gap in your external walls with a protective, thermally resistant material, which acts as a continuous barrier to keep warmth inside the home.

This effective sealing of the wall cavity also minimises the infiltration of cold air, leading to noticeably fewer draughts and a more stable, comfortable indoor temperature throughout the year.

For homeowners in Dunmore seeking this upgrade, Premier Insulations is an SEAI-registered installer you can trust, providing professional cavity wall insulation services to properties across Dunmore and the surrounding areas.

The result is a tangible sense of calm comfort in your living space, accompanied by the welcome benefit of lower energy bills.

Is your home in Dunmore suitable?

Inspecting Dunmore homes for cavity wall insulation suitability requires a thorough assessment of several key factors. First, we verify the cavity width is appropriate and check for any existing moisture issues that could compromise insulation performance. Additionally, the inspection includes identifying any older wiring within the cavity that may need attention prior to installation. Finally, we evaluate the property's exposure to wind-driven rain to ensure the chosen insulation material and installation method will provide long-term protection and energy efficiency.

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.
