Make your Dublin home easier to heat

Cavity wall insulation significantly reduces heat loss in Dublin homes by filling the gap between the outer and inner brickwork with a protective material, creating a highly effective thermal barrier that retains warmth.

This barrier not only keeps heat in but also minimises the infiltration of cold air, resulting in noticeably fewer draughts and a more consistent indoor temperature throughout the property.

For a professional installation, Premier Insulations is an SEAI-registered installer, trusted to service homes across Dublin and its surrounding areas to the highest standard.

This upgrade ultimately cultivates a sense of calm comfort within your home while concurrently leading to lower energy consumption and reduced heating bills.

Is your home in Dublin suitable?

Inspecting Dublin homes for cavity wall insulation suitability involves a thorough assessment of several key factors. First, we verify the cavity width to ensure it meets the minimum requirement for effective insulation material installation. The inspection also includes rigorous moisture testing to identify any existing dampness and a careful check of electrical wiring to prevent future hazards. Finally, we evaluate the property's exposure levels to determine if additional protective measures are needed against wind-driven rain, ensuring a durable and energy-efficient upgrade.

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.
