Make your Carrickfergus home easier to heat

Cavity wall insulation significantly reduces heat loss in Carrickfergus homes by filling the gap between external and internal walls with an effective insulating material. This process creates a thermal barrier that not only retains warmth but also minimises cold spots and leads to noticeably fewer draughts throughout the property.

For homeowners in Carrickfergus and the surrounding areas, Premier Insulations operates as an experienced installer, ensuring all work meets the highest standards for quality and grant eligibility.

This upgrade fosters a consistently comfortable living environment while concurrently delivering lower energy bills.

Is your home in Carrickfergus suitable?

Inspecting Carrickfergus homes for cavity wall insulation begins with a crucial cavity width measurement, ensuring the gap is within the standard range for effective material filling. A thorough moisture assessment is then conducted to identify any existing dampness, which must be remedied prior to any installation. The survey also includes checking for any hidden wiring or pipes within the wall that could be compromised. Finally, the property's exposure to prevailing wind-driven rain is evaluated, a key consideration for the long-term performance and suitability of the insulation in the local coastal climate.

The two primary cavity wall insulation systems are partial-fill and full-fill. Partial-fill involves installing a rigid insulation board against the inner leaf of the wall, leaving an air gap that enhances weather resistance. Full-fill systems completely pack the cavity with insulating material like mineral wool or beads, offering superior thermal performance but requiring careful installation to prevent moisture bridging. The suitability of each system depends on the property's exposure and masonry condition.
