Grenagh Cavity Wall Insulation
Warmer walls, lower bills, SEAI-supported upgrades in Grenagh
Make your Grenagh home easier to heat
Cavity wall insulation significantly reduces heat loss in homes by filling the gap between the inner and outer layers of the wall with a specialised material, which acts as a highly effective thermal barrier. This continuous layer of insulation also helps to seal gaps, resulting in noticeably fewer draughts and a more consistent indoor temperature throughout the property. For homeowners in Grenagh, Premier Insulations is an SEAI-registered installer, providing expert cavity wall insulation services to the local area and its surrounds.
This upgrade ultimately fosters a sense of calm comfort within the home while delivering tangible savings on energy bills.
Is your home in Grenagh suitable?
Inspecting Grenagh homes for cavity wall insulation suitability involves a thorough assessment of several key factors. A borescope inspection is first used to verify the cavity width is uniform and meets the minimum requirement, typically 50mm. The cavity must also be checked for any significant moisture penetration, debris, or obstructions such as old mortar droppings that could bridge the gap. Furthermore, the surveyor will identify the presence of any electrical wiring within the cavity and assess the property's exposure level to wind-driven rain to ensure the chosen insulation system is appropriate.
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. Conversely, full-fill uses loose-fill materials like beads or foam that completely occupy the cavity, providing excellent thermal performance for homes in sheltered areas.
