Bangor Cavity Wall Insulation
Warmer walls, lower bills, SEAI-supported upgrades in Bangor
Make your Bangor 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 barrier to keep warmth inside.
This barrier not only retains heat but also helps to minimise cold spots and draughts, creating a more consistent and comfortable indoor temperature throughout the property.
As an SEAI-registered installer, Premier Insulations provides this service to homeowners in Bangor and the surrounding areas, ensuring the work meets the highest standards for quality and grant eligibility.
The result is a noticeably more comfortable living environment coupled with lower energy bills throughout the year.
Is your home in Bangor suitable?
Inspecting Bangor homes for cavity wall insulation suitability involves a thorough assessment of several key factors. A borescope inspection is first conducted to verify the cavity width is uniform and clear of significant debris. We then check for any signs of existing moisture penetration and identify the location of electrical wiring to ensure it complies with safety standards. Finally, the property's exposure to wind-driven rain is evaluated, as this determines the need for a full-fill or partial-fill insulation system to prevent future moisture issues.
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.
