External Wall Insulation in County Meath

A job typically starts from €180 to €220. Final figures depend on extras, architectural details, and chosen finishes — such as whether silicone-based acrylic render is required for homes close to the sea or exposed areas, and whether window cills subject to high water runoff require special powder coating. As an SEAI Registered Contractor (#10423), Isotherm deducts your SEAI grant (up to €8,000 for detached, €6,000 for semi-detached/end-terrace, €3,500 for mid-terrace, and €3,000 for apartments) directly from your invoice at source.

For the vast majority of suburban housing estates and detached homes across County Meath, external wall insulation is classified as Exempted Development under Section 4(1)(h) of the Planning and Development Act 2000, provided the external silicone render finish matches the character of the neighborhood. If your property is a Protected Structure or located in an Architectural Conservation Area (ACA)—such as parts of historic Trim, Kells, or Slane—consultation with Meath County Council is required before altering the facade. We assess planning exemptions during your free site survey.

Our operations depot and fabrication workshop are located at Unit 20, Westlink Industrial Estate, Kylemore Road, Inchicore, Dublin 10 (D10 TD35). Traveling via the M50, N2, and M3 corridors, our installation crews reach South Meath (Ashbourne, Dunboyne, Ratoath, Dunshaughlin) in 20 to 25 minutes, and Navan or Trim in 35 to 40 minutes, ensuring daily site supervision, prompt delivery of scaffold materials, and direct project management.

County Meath consists of flat, open agricultural plains subject to strong wind-driven rain and freezing winter dampness. Uninsulated 9-inch hollow concrete blockwork or solid masonry absorbs moisture, accelerating heat loss. We install NSAI-certified Baumit systems featuring high-density graphite EPS (λ = 0.031 W/mK) and vapour-permeable Baumit SilikonTop silicone render. The finish repels driving rain while allowing trapped indoor moisture to escape, preventing algae bloom and exterior cracking permanently.

When 100mm to 150mm of external insulation is bonded to your outer walls, original concrete window sills lose their overhang projection. We install bespoke powder-coated aluminium window sills fabricated by our sister workshop, Cills.ie, located in our Inchicore depot. Each sill features welded watertight end caps, thermal barrier pads, and extended drip channels to guarantee water drains away cleanly.

To qualify for the SEAI Better Energy Homes grant in County Meath, your property must have been built and occupied on or before 31 December 2010 (verified by ESB MPRN meter registration). Furthermore, under the updated 2026 SEAI second wall measure rules, homes that previously received a cavity wall bead grant can now also claim the full €6,000 to €8,000 external wall insulation grant to reach an A-rated building envelope.
