Make your Coolboy home easier to heat

Cavity wall insulation significantly reduces heat loss in Coolboy homes by filling the gap between external and internal walls with an effective insulating material.

This creates a continuous thermal barrier that not only retains warmth but also minimises cold spots and draughts, leading to a more consistently comfortable indoor environment throughout the year.

For homeowners in Coolboy 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.

Consequently, residents can enjoy a noticeably warmer, calmer living space while also benefiting from lower annual energy bills.

Is your home in Coolboy suitable?

Inspecting Coolboy homes for cavity wall insulation suitability requires a thorough assessment of several key factors. First, we must verify the cavity width meets the minimum requirement to ensure proper material installation and performance. A critical moisture check is then conducted to identify any existing dampness, as insulating a wet cavity can lead to serious problems. Finally, we inspect for any hidden wiring or obstructions within the wall and assess the property's exposure to wind-driven rain, which influences the specification of the insulation material.

The two primary cavity wall insulation systems are blown mineral fibre and injected foam. Blown mineral fibre, such as glass or rock wool, is a non-combustible material ideal for most standard cavities, providing excellent thermal and acoustic performance. Alternatively, polyurethane foam is injected as a liquid that expands to fill the cavity, forming a highly effective air-tight seal particularly beneficial for properties with irregular wall constructions.

What you’ll gain

Benefits of cavity wall insulation Coolboy

• Lower heating bills: Cavity wall insulation acts as a thermal barrier, significantly reducing heat loss. This means your heating system works less to maintain a comfortable temperature, leading to substantial savings on your energy bills throughout the year in Coolboy.

• Warmer, more comfortable home: By preventing warm air from escaping, insulation eliminates cold spots and drafts. This creates a consistently warmer and more comfortable living environment for you and your family during cooler months.

• Reduced noise from outside: The insulating material within your cavity walls also serves as an effective sound absorber. This helps dampen external noise from traffic or neighbourhood activity, resulting in a quieter, more peaceful home.

• Increased property value: A well-insulated home is a key selling point. An official BER certificate from Premier Insulations proves your property’s energy efficiency, making it more attractive to potential buyers and increasing its market value.
