Ballymena Cavity Wall Insulation
Warmer walls, lower bills, SEAI-supported upgrades in Ballymena
Make your Ballymena home easier to heat
Cavity wall insulation significantly reduces heat loss in Ballymena homes by filling the gap between the outer and inner brickwork with a protective insulating material.
This barrier not only retains warmth more effectively but also minimises cold spots and draughts, leading to a more consistently comfortable indoor environment throughout the year.
For a professional installation, Premier Insulations is an SEAI-registered installer trusted to service properties in Ballymena and the surrounding localities.
This upgrade ultimately fosters a sense of calm comfort within the home while concurrently delivering lower energy bills.
Is your home in Ballymena suitable?
Inspecting a Ballymena home for cavity wall insulation begins with verifying the cavity width, which must be sufficient to accommodate the insulating material. A thorough moisture assessment is then conducted to ensure the cavity is completely dry and free from any pre-existing damp issues. The inspection also includes checking for any hidden wiring or debris within the wall and evaluating the property's exposure to wind-driven rain, a key consideration in the local climate. These essential checks confirm the property's suitability and ensure a safe, effective, and long-lasting insulation installation.
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.
