Knock Cavity Wall Insulation
Warmer walls, lower bills, SEAI-supported upgrades in Knock
Make your Knock home easier to heat
Cavity wall insulation is a highly effective method for enhancing the thermal efficiency of a home in Knock by filling the gap between the outer and inner brickwork with a specialised material.
This barrier significantly reduces heat loss through the walls, ensuring your home stays warmer for longer, while also helping to block unwanted draughts from penetrating the building envelope.
For homeowners in Knock and the surrounding areas, Premier Insulations is an SEAI-registered installer, guaranteeing that the work is completed to the highest standard and may qualify for grant support.
This upgrade ultimately fosters a more consistently comfortable living environment while contributing to noticeably lower energy bills.
Is your home in Knock suitable?
Inspecting Knock homes for cavity wall insulation suitability requires a thorough assessment of several key factors. First, the cavity width must be measured to ensure it falls within the acceptable range for standard insulation materials. A detailed moisture survey is then essential to confirm the walls are dry and free from dampness that could be trapped. Finally, inspectors must check for any existing wiring or service conduits within the cavity and evaluate the property's exposure level to driven rain, as highly exposed locations may require specialized solutions.
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 fire resistance and sound absorption. Alternatively, insulating foam beads or binder-infused fibres are injected, forming a thermally efficient barrier particularly effective for filling irregular cavities and mitigating water penetration in exposed locations. A professional assessment is crucial to determine the most suitable system based on a property's specific construction and exposure.

Benefits of cavity wall insulation Knock
• Lower heating bills: Cavity wall insulation from Premier Insulations acts as a highly effective thermal barrier, significantly reducing heat loss. This means your Knock home requires less energy to stay warm, leading to substantial savings on your annual heating costs.
• Warmer, more comfortable home: By preventing warm air from escaping and cold drafts from entering, our insulation eliminates cold spots. This creates a consistently warmer and more comfortable living environment throughout your entire property during Knock's cooler months.
• Reduced noise from outside: The insulation material within your cavity walls also serves as an excellent sound absorber. This helps to dampen external noise pollution, such as traffic or neighbourhood sounds, resulting in a quieter and more peaceful home.
