Craigavon Cavity Wall Insulation
Warmer walls, lower bills, SEAI-supported upgrades in Craigavon
Make your Craigavon 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 barrier to keep warmth inside the building.
This barrier not only retains heat more efficiently but also helps to create a more sealed building envelope, resulting in noticeably fewer draughts throughout the property.
For homeowners in Craigavon, Premier Insulations is an SEAI-registered installer that provides this service locally, ensuring work is completed to the highest standards.
This upgrade fosters a consistently comfortable living environment while concurrently leading to lower energy bills.
Is your home in Craigavon suitable?
Inspecting Craigavon homes for cavity wall insulation suitability involves a thorough assessment of several key factors. A borescope survey is first conducted to verify the cavity width is uniform and suitable for insulation material injection. The cavity is also meticulously checked for any signs of moisture penetration, pre-existing debris, or obstructions such as electrical wiring that could pose a hazard. Finally, the property's exposure level is evaluated, as severe wind-driven rain can influence the specification of materials to ensure long-term performance and prevent moisture-related issues.
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 a small air gap that enhances weather resistance. In contrast, the full-fill method completely packs the cavity with a blown material like mineral wool or polystyrene beads, providing a continuous thermal barrier. The suitability of each system depends on specific site conditions, including exposure to wind-driven rain and the construction of the existing wall.
