Sligo Cavity Wall Insulation
Warmer walls, lower bills, SEAI-supported upgrades in Sligo
Make your Sligo home easier to heat
Cavity wall insulation significantly reduces heat loss in homes by filling the gap in external walls with a protective, insulating material.
This barrier not only retains warmth more effectively but also minimises cold spots and draughts, creating a more consistent and comfortable indoor temperature throughout the property.
For homeowners in Sligo, Premier Insulations is an SEAI-registered installer, providing trusted cavity wall insulation services across the county and its surrounding regions.
This upgrade ultimately fosters a calmer, more comfortable living environment while delivering tangible savings on energy bills.
Is your home in Sligo suitable?
Inspecting a Sligo home for cavity wall insulation suitability involves several critical checks. First, we must verify the cavity width meets the minimum requirement, typically 50mm, to ensure proper material filling. A thorough moisture assessment is then conducted to identify any existing dampness or water ingress that could compromise the insulation's performance. Finally, we inspect for obstructions like electrical wiring and evaluate the property's exposure to wind-driven rain, as these factors directly influence both the installation process and the long-term effectiveness of the insulation system.
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 systems completely pack the cavity with insulating material like mineral wool or beads, offering superior thermal performance but requiring careful installation to prevent moisture bridging. The suitability of each system depends on the property's exposure to wind-driven rain and the condition of the existing cavity.
