Make your Charlestown home easier to heat

Cavity wall insulation significantly reduces heat loss by filling the gap in your external walls with a protective, thermally resistant material.

This creates a continuous barrier that not only retains warmth but also prevents cold air from penetrating, resulting in noticeably fewer draughts throughout the home.

For homeowners in Charlestown, Premier Insulations is an SEAI-registered installer, ensuring that all work meets the highest standards for both quality and grant eligibility in the local area.

This upgrade provides a consistent sense of comfort while delivering tangible savings on your energy bills.

Is your home in Charlestown suitable?

Inspecting Charlestown homes for cavity wall insulation suitability involves a thorough assessment of several key factors. A borescope inspection is first used to determine the cavity width and confirm it falls within the recommended range for the chosen insulation material. We then meticulously check for any signs of moisture penetration, debris, or obsolete wiring within the cavity that could pose a problem. Finally, the property's exposure to wind-driven rain is evaluated to ensure the installation will perform effectively and protect the building fabric long-term.

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.
