Rathmullen Cavity Wall Insulation
Warmer walls, lower bills, SEAI-supported upgrades in Rathmullen
Make your Rathmullen 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 the building.
This process also leads to fewer draughts, as it seals the voids that previously allowed cold air to penetrate into the living spaces, thereby creating a more consistent and comfortable indoor temperature throughout the property.
For homeowners in Rathmullen, Premier Insulations is an SEAI-registered installer that provides this essential service to the local area and its surrounding communities.
Consequently, residents can enjoy a noticeably warmer, calmer home environment while also benefiting from lower annual energy bills.
Is your home in Rathmullen suitable?
Inspecting Rathmullen homes for cavity wall insulation suitability involves 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 existing debris or obstructions. We then conduct comprehensive moisture and dampness checks to ensure the cavity is completely dry, as insulating a damp wall can trap moisture and lead to problems. Finally, the walls are examined for any signs of deteriorating mortar, exposed wiring or services, and the property's exposure to wind-driven rain is evaluated to guarantee a successful and long-lasting installation.
The two main 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. Injected bead or foam systems, which bind insulation granules together, are often chosen for their high thermal performance and resistance to moisture penetration in suitable wall constructions.
