Coleraine Cavity Wall Insulation
Warmer walls, lower bills, Grant-supported upgrades in Coleraine
Make your Coleraine home easier to heat
Cavity wall insulation significantly reduces heat loss in homes by filling the gap between the inner and outer walls with an effective insulating material, which acts as a barrier to keep warmth inside.
This barrier not only retains heat but also minimises cold spots and draughts, creating a more consistently comfortable and sealed living environment throughout the property.
For homeowners in Coleraine, Premier Insulations is an SEAI-registered installer that provides this service, ensuring quality workmanship and compliance with grant-aid requirements across the town and its surrounding areas.
This upgrade ultimately fosters a sense of calm comfort within your home while leading to noticeably lower energy bills.
Is your home in Coleraine suitable?
Inspecting a Coleraine home for cavity wall insulation begins with a professional assessment of several key factors. A borescope inspection is used to verify the cavity width is uniform and suitable for filling, typically between 50mm and 100mm. The surveyor also checks for any signs of moisture penetration, assesses the condition of existing wiring or services within the wall, and evaluates the property's exposure to wind-driven rain. This comprehensive evaluation ensures that only suitable properties are insulated, thereby safeguarding the building's fabric and guaranteeing long-term thermal performance.
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 Coleraine
• Lower heating bills: Cavity wall insulation acts as a thermal barrier, significantly reducing heat loss. This improved energy efficiency means your heating system works less, leading to substantial savings on your energy bills throughout the year in Coleraine's climate.
• Warmer, more comfortable home: By preventing warm air from escaping, insulation helps maintain a consistent and comfortable temperature in your home. You will enjoy a cosier living environment, free from cold spots and drafts during colder months.
• Reduced noise from outside: The insulation material within your cavity walls also serves as an effective sound absorber. This can noticeably reduce the transmission of external noise from traffic or neighbours, creating a more peaceful and tranquil home.
