Kilrea Cavity Wall Insulation
Warmer walls, lower bills, SEAI-supported upgrades in Kilrea
Make your Kilrea home easier to heat
Cavity wall insulation significantly reduces heat loss by filling the gap in your external walls with an effective insulating material, preventing warmth from escaping and creating a more stable indoor temperature.
This barrier not only retains heat but also minimises cold spots and draughts, leading to a more consistently comfortable living environment throughout your home.
For homeowners in Kilrea, Premier Insulations is an SEAI-registered installer, ensuring that your cavity wall insulation is fitted to the highest standards for maximum efficiency and grant compliance across the local area.
This upgrade ultimately fosters a sense of calm comfort while delivering noticeably lower energy bills.
Is your home in Kilrea suitable?
Inspecting Kilrea 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 ensure it falls within the recommended range for the chosen insulation material. We then meticulously check for any signs of moisture penetration or existing dampness, as insulating a wet cavity can lead to serious problems. The survey also includes identifying the location of any electrical wiring and evaluating the property's exposure to wind-driven rain, which are critical for both safety and long-term performance.
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, polyurethane bead or foam systems create a highly efficient thermal barrier by expanding to seal the cavity completely, making them ideal for homes requiring superior insulation performance where conditions are appropriate.
