Fahan Cavity Wall Insulation
Warmer walls, lower bills, SEAI-supported upgrades in Fahan
Make your Fahan home easier to heat
Cavity wall insulation significantly reduces heat loss in Fahan homes by filling the gap between 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 and a more stable indoor temperature throughout the year.
For homeowners in Fahan and the surrounding locality, Premier Insulations is an SEAI-registered installer, ensuring the work is completed to the highest standard and may qualify for grant support.
This upgrade ultimately fosters a more comfortable living environment while contributing to lower energy consumption and reduced heating bills.
Is your home in Fahan suitable?
Inspecting Fahan homes for cavity wall insulation suitability involves a thorough assessment of several key factors. A borescope inspection is first used to determine the cavity width and confirm it is clear of significant debris that could hinder installation. Crucially, the walls are checked for persistent moisture issues and the presence of old electrical wiring or other services that may require attention prior to work commencing. Finally, the property's exposure to wind-driven rain is evaluated to ensure the chosen insulation material and installation method are appropriate for the local conditions.
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.
