Castlebar Cavity Wall Insulation
Warmer walls, lower bills, SEAI-supported upgrades in Castlebar
Make your Castlebar home easier to heat
Cavity wall insulation significantly reduces heat loss by filling the gap in your home's walls with a protective, thermally efficient material that acts as a constant barrier against the cold.
This barrier not only retains warmth but also helps to eliminate the number of cold draughts that can permeate through uninsulated walls, creating a more stable and comfortable indoor environment throughout the year.
For homeowners in Castlebar, Premier Insulations is an SEAI-registered installer that provides this essential service to properties across the town and the wider local area.
This upgrade ultimately cultivates a profound sense of calm comfort within your home, accompanied by the tangible benefit of lower energy consumption and reduced heating bills.
Is your home in Castlebar suitable?
Inspecting Castlebar homes for cavity wall insulation suitability requires a thorough assessment of several key factors. A borescope inspection is first used to determine the cavity width and confirm it is clear of significant debris. We then check for any signs of moisture penetration and note the position of electrical wiring or other services that could be present within the wall. Finally, the property's exposure to wind-driven rain is evaluated, as this influences the choice of insulation material to ensure long-term performance and prevent dampness.
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.
