Johnstown Cavity Wall Insulation
Warmer walls, lower bills, SEAI-supported upgrades in Johnstown
Make your Johnstown home easier to heat
Cavity wall insulation significantly reduces heat loss in homes by filling the gap in external walls with an effective insulating material, which acts as a thermal barrier to keep warmth inside.
This barrier not only retains heat but also helps to create a more sealed building envelope, resulting in noticeably fewer draughts and a more consistent indoor temperature throughout the property.
For homeowners in Johnstown, Premier Insulations is an SEAI-registered installer that provides this service locally, ensuring the work meets the highest standards for quality and grant eligibility.
This upgrade ultimately fosters a sense of calm comfort within the home while concurrently leading to lower energy consumption and reduced heating bills.
Is your home in Johnstown suitable?
Inspecting Johnstown homes for cavity wall insulation suitability involves a thorough assessment of several key factors. First, we verify the cavity width meets minimum requirements to ensure proper material installation and performance. Concurrently, moisture levels are meticulously checked to prevent future damp issues, and any existing wiring or plumbing within the wall is carefully examined. Finally, the property's exposure to wind-driven rain is evaluated to confirm it is an appropriate candidate for this energy-efficient upgrade.
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 property types, 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 performance but requiring a thorough professional assessment of the wall's suitability to prevent moisture issues.
