Offaly Cavity Wall Insulation
Warmer walls, lower bills, SEAI-supported upgrades in Offaly
Make your Offaly home easier to heat
Cavity wall insulation significantly reduces heat loss in homes by filling the gap in external walls with a protective, insulating material.
This creates a continuous thermal barrier that not only retains warmth but also minimises cold spots and draughts throughout the property.
For homeowners in Offaly, Premier Insulations is an SEAI-registered installer, providing expert cavity wall insulation services across the county and surrounding areas.
This upgrade fosters a more consistently comfortable living environment while contributing to noticeably lower energy bills.
Is your home in Offaly suitable?
Inspecting Offaly homes for cavity wall insulation suitability involves several critical checks. First, we must verify the cavity width is sufficient, typically at least 50mm, to accommodate the insulating material effectively. A thorough moisture assessment is then conducted to ensure the cavity is completely dry and free from pre-existing damp issues that could be exacerbated. Finally, we inspect for obstructions like old wiring or debris and assess the property's exposure level, as homes in highly exposed areas may require specific detailing to prevent wind-driven rain penetration.
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 ideal for most standard cavities, providing excellent thermal and acoustic performance. Alternatively, polyurethane foam is injected as a liquid that expands to fill the cavity, forming a highly effective air-tight seal particularly beneficial for properties with irregular wall constructions.
