Portmagee Cavity Wall Insulation
Warmer walls, lower bills, SEAI-supported upgrades in Portmagee
Make your Portmagee home easier to heat
Cavity wall insulation significantly reduces heat loss in homes by filling the gap between the outer and inner walls with a protective material, preventing warmth from escaping through the masonry.
This creates a continuous thermal barrier that minimises cold spots and leads to noticeably fewer draughts throughout the property.
For homeowners in Portmagee, Premier Insulations is an SEAI-registered installer that provides this essential service to the local area, ensuring all work meets the highest standards for grants and quality.
This upgrade ultimately fosters a more consistently comfortable living environment while delivering tangible savings on energy bills.
Is your home in Portmagee suitable?
Inspecting Portmagee homes for cavity wall insulation suitability requires a thorough assessment of several key factors. A borescope inspection is first used to confirm the cavity width is uniform and meets the minimum requirement, while also checking for any debris that could cause bridging. Concurrently, a moisture meter is essential to detect any existing dampness within the wall, and a visual check identifies potential issues from older wiring or vent pipes that need addressing. Finally, the property's exposure to the prevailing Atlantic winds and driving rain is evaluated, as this significantly influences the choice of insulation material and installation method.
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.
