Make your Mayo 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.

This barrier not only retains heat more efficiently but also leads to fewer draughts, creating a more consistent and comfortable indoor temperature throughout the property.

For homeowners in Mayo, Premier Insulations is an SEAI-registered installer that provides this service, ensuring quality workmanship and compliance with national standards across the county and its surrounding regions.

The result is a home that offers a greater sense of calm comfort while also contributing to noticeably lower energy bills.

Is your home in Mayo suitable?

Inspecting a Mayo home for cavity wall insulation begins with verifying the cavity width, which must be at least 50mm to be suitable. A thorough moisture assessment is then conducted to ensure the inner leaf is completely dry and there are no existing damp issues. The surveyor must also check for any hidden wiring or services within the cavity that could pose a hazard. Finally, the property's exposure rating is evaluated, as homes in severe exposure zones may require specific insulation systems to withstand driven rain.

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. Full-fill utilizes loose-fill materials like beads or foam that completely occupy the cavity, offering excellent thermal performance for homes in sheltered areas with good masonry.
