Make your Cork home easier to heat

Cavity wall insulation significantly reduces heat loss by filling the gap in your external walls with a protective, thermally efficient material that acts as a continuous barrier against the cold.

This barrier not only retains valuable warmth but also helps to eliminate the number of cold draughts that can permeate through uninsulated masonry, creating a more consistent and stable internal temperature.

For homeowners in Cork, Premier Insulations is an SEAI-registered installer, providing expert cavity wall insulation services throughout the county and its surrounding areas.

This upgrade ultimately fosters a more comfortable living environment while contributing to noticeably lower energy bills.

Is your home in Cork suitable?

Inspecting Cork homes for cavity wall insulation suitability involves a thorough assessment of several key factors. A borescope inspection is essential to determine the cavity width and confirm it meets the minimum requirement for insulation material injection. The surveyor must also check for any signs of moisture penetration, assess the condition and placement of electrical wiring, and evaluate the property's exposure to wind-driven rain. This comprehensive evaluation ensures the installation will be effective, safe from damp issues, and compliant 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 and clear cavity walls.

Benefits of cavity wall insulation Cork

• Lower heating bills: By effectively trapping heat within your home, cavity wall insulation significantly reduces the amount of energy required to maintain a comfortable temperature, leading to substantial savings on your annual heating costs in Cork's climate.

• Warmer, more comfortable home: This insulation acts as a continuous thermal barrier, eliminating cold spots and draughts to create a consistently warmer and more comfortable living environment throughout the entire property.

• Reduced noise from outside: The insulation material within the cavity also absorbs sound, providing an effective buffer against external noise pollution from traffic or neighbourhood activity for a quieter, more peaceful home.
