Make your Raphoe home easier to heat

Cavity wall insulation is a highly effective method for significantly reducing heat loss within homes in Raphoe.

By filling the cavity between the inner and outer walls with insulating material, it creates a powerful thermal barrier that not only retains warmth but also minimises the infiltration of cold air, leading to noticeably fewer draughts throughout the property.

For homeowners in Raphoe and the surrounding areas, Premier Insulations operates as an SEAI-registered installer, ensuring that all work is completed to the highest standards and may qualify for available grant support.

This upgrade fosters a consistently comfortable living environment while concurrently delivering tangible reductions in energy consumption and heating costs.

Is your home in Raphoe suitable?

Inspecting Raphoe homes for cavity wall insulation suitability involves a thorough assessment of several key factors. We first verify the cavity width is appropriate and consistent, typically measuring at least 50mm. A critical moisture check is then conducted to ensure the cavity is free from dampness or water ingress that could lead to future problems. The inspection also includes identifying any existing wiring or services within the cavity and evaluating the property's exposure to wind-driven rain, which is essential for determining the correct insulation specification for local conditions.

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 cavity walls.
