Garvagh Cavity Wall Insulation
Warmer walls, lower bills, SEAI-supported upgrades in Garvagh
Make your Garvagh home easier to heat
Cavity wall insulation significantly reduces heat loss in homes by filling the gap between the inner and outer walls with an effective insulating material, which acts as a continuous thermal barrier.
This barrier not only retains more warmth within the property but also helps to minimise the number of cold draughts that can permeate through the wall structure.
For homeowners in Garvagh, Premier Insulations provides this service as an SEAI-registered installer, ensuring the work is completed to the highest standard for properties in the town and the wider local area.
This upgrade ultimately fosters a more consistently comfortable living environment while contributing to noticeably lower energy bills.
Is your home in Garvagh suitable?
Inspecting a Garvagh home for cavity wall insulation begins with verifying the cavity width is suitable, typically between 50mm and 100mm. A thorough moisture assessment is then conducted to ensure the cavity is completely dry and free from dampness or existing water ingress. We also meticulously check for any hidden wiring or services within the wall that could pose a hazard once insulated. Finally, the property's exposure to wind-driven rain is evaluated to confirm it is an appropriate candidate for this effective energy-saving measure.
The two primary cavity wall insulation systems are blown mineral fibre and injected foam. Blown mineral fibre, such as glass or rock wool, is suitable for most standard cavities and is non-combustible with excellent fire resistance. Injected foam insulation, typically urea-formaldehyde, expands to fill irregular gaps, making it effective for properties where cavity walls are less uniform. A professional assessment is essential to determine the correct system based on the property's construction and exposure.
