Make your Portmarnock home easier to heat

Cavity wall insulation significantly reduces heat loss in Portmarnock homes by filling the gap between external and internal walls with a high-performance material, creating a powerful thermal barrier that retains warmth.

This barrier not only keeps heat in during the winter but also minimises cold air infiltration, leading to noticeably fewer draughts and a more stable indoor temperature throughout the year.

For homeowners in Portmarnock and the surrounding areas, Premier Insulations is an SEAI-registered installer, ensuring the work is completed to the highest standard and may qualify for grant support.

This upgrade cultivates a sense of calm comfort while concurrently delivering lower energy bills.

Is your home in Portmarnock suitable?

Inspecting Portmarnock homes for cavity wall insulation suitability involves a thorough assessment of several key factors. A primary check is confirming the cavity width is appropriate and uniform, ensuring it can adequately accommodate the insulating material. We also meticulously check for any existing moisture penetration or dampness, which must be rectified prior to installation, and identify the location of any electrical wiring within the cavity. Finally, the property's exposure to wind-driven rain is evaluated to determine if additional protective measures are necessary for a durable and effective installation.

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 a small air gap that enhances weather resistance. Full-fill systems completely pack the cavity with insulating beads or foam, offering superior thermal performance and being suitable for most standard cavity widths in suitable homes.
