Dundalk Cavity Wall Insulation
Warmer walls, lower bills, SEAI-supported upgrades in Dundalk
Make your Dundalk home easier to heat
Cavity wall insulation significantly reduces heat loss in homes by filling the gap in external walls with an effective insulating material, which acts as a barrier to keep warmth inside.
This barrier not only retains heat but also leads to fewer draughts, creating a more consistent and comfortable indoor temperature throughout the property.
For homeowners in Dundalk, Premier Insulations is an SEAI-registered installer that provides this service to the town and its surrounding areas.
Ultimately, this upgrade cultivates a sense of calm comfort within the home while delivering noticeably lower energy bills.
Is your home in Dundalk suitable?
Inspecting a Dundalk home for cavity wall insulation begins with a thorough assessment of several key factors. A borescope inspection is essential to confirm the cavity width is uniform and suitable for filling, typically between 50mm and 100mm. We then meticulously check for any signs of moisture penetration or existing debris within the wall, as these must be remedied first to prevent future problems. The survey also includes verifying the condition of electrical wiring and ensuring the property's exposure level is appropriate, as severe wind-driven rain can influence the choice of insulation material.
The two primary cavity wall insulation systems are blown mineral fibre and injected foam. Blown mineral fibre, such as glass or rock wool, is suitable for most standard cavities and is non-combustible. Injected bead or foam systems fill the cavity more completely, making them ideal for properties with irregular wall constructions, and they provide excellent thermal performance.
