Shillelagh Cavity Wall Insulation
Warmer walls, lower bills, SEAI-supported upgrades in Shillelagh
Make your Shillelagh home easier to heat
Cavity wall insulation significantly reduces heat loss in homes by filling the gap between the inner and outer brickwork with a specialised material, creating an effective thermal barrier that keeps warmth inside.
This barrier not only retains heat but also minimises the infiltration of cold air, resulting in noticeably fewer draughts and a more consistent indoor temperature throughout the property.
For homeowners in Shillelagh, Premier Insulations is an SEAI-registered installer, ensuring that all work meets the highest standards for quality and grant eligibility while serving this area and its surrounds.
This upgrade fosters a sense of calm comfort within your home while concurrently leading to lower energy consumption and reduced heating bills.
Is your home in Shillelagh suitable?
Inspecting Shillelagh homes for cavity wall insulation begins with a thorough assessment of several key factors. A borescope inspection is essential to determine the cavity width and confirm it meets the minimum requirement, while also checking for any existing debris or obstructions. We must diligently identify any signs of moisture penetration or dampness within the cavity, as insulation cannot be installed in wet walls. Furthermore, the survey includes checking for the presence of old electrical wiring within the cavity and evaluating the property's exposure to wind-driven rain, which is crucial for determining the need for rendered finishes.
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 Shillelagh
• Lower heating bills: Cavity wall insulation acts as a thermal barrier, significantly reducing heat loss. This means your heating system works less, leading to substantial savings on your energy bills throughout the year in Shillelagh.
• Warmer, more comfortable home: By preventing warm air from escaping, insulation eliminates cold spots and drafts. Your home will retain a consistent, comfortable temperature, creating a cozier living environment during cooler months.
• Reduced noise from outside: The insulation material within your cavity walls also acts as a sound absorber. This helps dampen external noises from traffic or weather, resulting in a quieter and more peaceful home.
• Increased property value: A well-insulated home is a key selling point. An improved Building Energy Rating (BER) and lower running costs make your property more attractive to potential buyers, thereby increasing its market value.
