Make your Castlerea home easier to heat

Cavity wall insulation significantly improves a home's thermal efficiency by filling the gap between the inner and outer leaves of the wall with a specialised material, thereby substantially reducing unwanted heat loss.

This creates a continuous thermal barrier that not only retains warmth but also minimises cold spots and the infiltration of draughts, leading to a more consistently comfortable indoor environment throughout the year.

For homeowners in Castlerea seeking these benefits, Premier Insulations operates as an SEAI-registered installer, ensuring that all work meets the highest standards for quality and grant eligibility while serving Castlerea and its surrounding localities.

This upgrade ultimately fosters a sense of calm, enduring comfort within your home, accompanied by the welcome advantage of lower energy bills.

Is your home in Castlerea suitable?

Inspecting Castlerea homes for cavity wall insulation suitability involves a thorough assessment of several key factors. We first measure the cavity width to ensure it meets the minimum requirement for effective material injection. A critical moisture check is then conducted to identify any existing dampness, as insulating a wet cavity can lead to serious problems. The survey also includes inspecting for any hidden wiring or obstructions within the wall and evaluating the property's exposure to wind-driven rain, which is essential for determining long-term performance and integrity.

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.
