Make your Kilkenny home easier to heat

Cavity wall insulation significantly reduces heat loss in homes by filling the gap between the inner and outer walls with a high-performance insulating material, creating a formidable thermal barrier that keeps warmth inside.

This barrier not only retains heat more effectively but also minimises the infiltration of cold air, resulting in noticeably fewer draughts and a more stable, comfortable indoor temperature throughout the year.

For homeowners in Kilkenny, Premier Insulations is an SEAI-registered installer that provides this essential service, ensuring the work is completed to the highest standards for properties across the city and surrounding counties.

This upgrade ultimately fosters a sense of calm comfort within your home, alongside the tangible benefit of lower energy bills.

Is your home in Kilkenny suitable?

Inspecting a Kilkenny home for cavity wall insulation begins with verifying the cavity width, which must be at least 50mm to accommodate the material. A thorough moisture assessment is then conducted to ensure the cavity is free from dampness or water ingress that could lead to problems. The inspection also includes checking for any existing wiring or services within the wall that may require special attention prior to installation. Finally, the property's exposure level is evaluated, as severe wind-driven rain conditions necessitate specific design considerations to guarantee 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 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 and clear cavity walls.
