Galway Cavity Wall Insulation
Warmer walls, lower bills, SEAI-supported upgrades in Galway
Make your Galway home easier to heat
Cavity wall insulation is a highly effective measure for homes in Galway, designed to fill the gap between brickwork with insulating material to significantly reduce the rate of heat transfer through the walls.
This process creates a continuous thermal barrier, which not only minimises heat loss but also helps to seal gaps that can cause uncomfortable and costly draughts throughout the property.
For a professional installation, Premier Insulations is an SEAI-registered installer, ensuring the work is completed to the highest standard for homeowners across Galway and its surrounding areas.
This upgrade cultivates a sense of calm, consistent comfort indoors while concurrently leading to lower energy bills.
Is your home in Galway suitable?
Inspecting a Galway 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 critical to ensure the cavity is free from dampness or water ingress, which could lead to problems post-installation. We also conduct checks for any existing wiring or services within the wall that may require special attention. Finally, the property's exposure to prevailing winds and driving rain is evaluated, as this influences the specification of materials and installation techniques to guarantee long-term performance and protection.
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.
