Make your Dunleer 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.

This barrier not only retains warmth but also minimises cold air infiltration, resulting in noticeably fewer draughts throughout the property.

For homeowners in Dunleer, Premier Insulations is an SEAI-registered installer that provides this service, ensuring all work meets the national standards for quality and energy efficiency.

This upgrade cultivates a consistently comfortable living environment while delivering tangible savings on energy bills.

Is your home in Dunleer suitable?

Inspecting a Dunleer home 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 filling. We then meticulously check for any signs of moisture penetration, assess the condition of existing wiring, and identify potential exposure issues from driving rain. This comprehensive evaluation ensures the property is a viable candidate, guaranteeing that the installation will be both safe and effective for long-term 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.
