Make your Glenties home easier to heat

Cavity wall insulation significantly reduces heat loss by filling the gap in your home's walls with a protective, thermally efficient material that acts as a continuous barrier against the cold.

This barrier not only retains warmth but also helps to eliminate the draughts commonly felt around windows, doors, and skirting boards, creating a more sealed and stable indoor environment.

For homeowners in Glenties, Premier Insulations is an SEAI-registered installer, ensuring that your insulation is fitted to the highest standards for both efficiency and grant eligibility across the local area.

This upgrade ultimately delivers a sense of calm comfort throughout your home, accompanied by noticeably lower energy bills.

Is your home in Glenties suitable?

Our inspection of Glenties homes for cavity wall insulation begins with a thorough assessment of cavity width, ensuring it meets the minimum requirement for effective material injection. We meticulously check for any signs of existing moisture or dampness within the wall, as this must be remedied prior to any installation. The survey also includes a careful examination of wiring and service entries for potential obstructions. Finally, we evaluate the property's exposure to wind-driven rain to determine if protective measures are necessary for long-term performance and integrity.

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 and masonry condition.
