Make your Oldcastle 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 Oldcastle, Premier Insulations is an SEAI-registered installer, trusted to provide this upgrade throughout the town and the surrounding local areas.

This results in a noticeably more comfortable living environment and a welcome reduction in energy bills.

Is your home in Oldcastle suitable?

Inspecting Oldcastle homes for cavity wall insulation suitability requires a thorough assessment of several key factors. First, the cavity width must be measured to ensure it falls within the acceptable range for the chosen insulation material. A detailed moisture inspection is also critical to identify any existing dampness or water ingress that must be rectified. Furthermore, the survey includes checking for any hidden wiring or services within the cavity and evaluating the property's exposure to wind-driven rain, which can influence material selection and installation methods.

The two primary cavity wall insulation systems are blown mineral fibre and injected foam. Blown mineral fibre, such as glass or rock wool, is suitable for most standard cavities, offering excellent fire resistance and moisture handling. Injected foam systems, like polyurethane bead, create a more seamless fill that is ideal for irregular wall cavities, providing superior thermal performance and rigidity.
