Make your Bellaghy home easier to heat

Cavity wall insulation is a highly effective measure for homes in Bellaghy, significantly improving their thermal performance and energy efficiency.

By filling the gap between the inner and outer leaves of your external walls with insulating material, this process drastically reduces the rate of conductive heat loss, ensuring your home stays warmer for longer while also sealing gaps that cause uncomfortable draughts.

For homeowners in Bellaghy seeking this upgrade, Premier Insulations operates as an SEAI-registered installer, guaranteeing that all work meets the rigorous standards required for grant approval and is carried out by certified professionals across the local area.

This results in a home that is consistently more comfortable throughout the year and leads to noticeably lower energy bills, providing lasting value and peace of mind.

Is your home in Bellaghy suitable?

Inspecting Bellaghy homes for cavity wall insulation suitability involves a thorough assessment of several key factors. We first determine the cavity width to ensure it meets the minimum requirement for effective material installation. A critical moisture check is then conducted within the cavity to identify any pre-existing dampness that could lead to problems. The survey also includes an examination for any hidden wiring or obstructions and an evaluation of the property's exposure to wind-driven rain, which is essential for long-term performance and compliance with building standards.

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 suitable for most properties, effectively filling the cavity to reduce heat loss. Alternatively, insulating foam is injected as a liquid that expands to create a seamless thermal barrier, offering excellent resistance to air leakage in homes with consistently sized cavity walls.

What you’ll gain

Benefits of cavity wall insulation Bellaghy

• 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 Bellaghy.

• Warmer, more comfortable home: By preventing warm air from escaping, this insulation eliminates cold spots and drafts. Your home will retain heat more effectively, creating a consistently warmer and more comfortable living environment for you and your family.

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

• Increased property value: An energy-efficient home is a valuable asset. Installing cavity wall insulation is a recognised home improvement that enhances your property's Energy Performance Certificate (EPC) rating, making it more attractive to potential buyers.
