Make your Killarney home easier to heat

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

This continuous layer of insulation also helps to eliminate cold spots and prevent air infiltration, resulting in noticeably fewer draughts throughout the property.

For homeowners in Killarney, Premier Insulations is an SEAI-registered installer, ensuring that all work meets the highest standards for quality and energy efficiency in the local area and beyond.

This upgrade ultimately fosters a more comfortable living environment while contributing to lower energy consumption and reduced heating bills.

Is your home in Killarney suitable?

Inspecting Killarney homes for cavity wall insulation suitability requires a thorough assessment of several key factors. First, we must verify the cavity width is sufficient and check for any existing moisture, which is a critical consideration given the local climate. The inspection also involves identifying any obstructions, such as electrical wiring or debris, that could complicate the installation process. Finally, we evaluate the property's exposure to wind-driven rain to ensure the chosen insulation material and method will perform effectively and durably.

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.
