Ashbourne External Wall Insulation & SEAI Grants
Projects typically start from €180 to €220. Isotherm deducts the SEAI grant directly from your invoice at source.
For homes subject to heavy exposure, we apply specialized silicone-based acrylic renders (such as Baumit SilikonTop) to provide exceptional rain repellency, algae protection, and vapor breathability.
For window cills where water runoff is high, we fit bespoke aluminium over-sills manufactured with a special protective powder coating from Cills.ie to guarantee 100% watertight drainage and long-term durability.
*Starting figures vary depending on project extras, architectural detailing, finish selection, silicone-based acrylic render requirements, and special powder coating for window cills. Fixed quotation provided after a free on-site survey.
Insulating Ashbourne Estates & Suburbs
Ashbourne developed rapidly across four main housing eras, each with distinct thermal and structural requirements.
Estates like Garden City, Crestwood, and Tudor Grove were built with 215mm hollow concrete block or 100mm twin-leaf cavities with little to no insulation. Wrapping external masonry locks heat inside the structural mass.
Developments like Archerstown Wood, Castleview, The Briars, and Brookville have partial cavity insulation. Cold reveals around windows and uninsulated gable corners remain primary sources of heat loss that EWI resolves completely.
Detached homes along the Ballybin Road, Ratoath Road, and Greenogue feature large wall areas exposed to South Meath winds. Our Baumit OpenSystem or ProSystem delivers comprehensive A/B BER transformations with €8,000 grant deduction.

Common questions from Ashbourne homeowners
How much does external wall insulation cost in Ashbourne in 2026?+
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 enhanced weather resistance, 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.
How fast can Isotherm crews reach Ashbourne from your depot?+
Our operations base and fabrication workshop are located at Unit 20, Westlink Industrial Estate, Kylemore Road, Inchicore, Dublin 10 (D10 TD35). Traveling via the M50 and N2 dual carriageway, our installation teams and scaffold trucks reach Ashbourne in just 22 to 25 minutes. This ensures daily project supervision and rapid turnaround.
Do I need planning permission for external insulation in Ashbourne?+
For almost all standard residential estates across Ashbourne, external wall insulation is classified as Exempted Development under Section 4(1)(h) of the Planning and Development Act 2000, provided the silicone render finish matches the local aesthetic. If your home is a listed structure or adjacent to a conservation zone along Frederick Street, we advise on exemption parameters during your initial site survey.
Why is the Baumit system ideal for Ashbourne's housing stock?+
Many Ashbourne homes built between the 1970s and 2000s feature 9-inch hollow block walls or partially insulated block cavities that suffer from severe cold bridging, surface condensation, and high heating bills. We wrap these walls with NSAI-certified Baumit graphite EPS (λ = 0.031 W/mK) and self-cleaning Baumit SilikonTop silicone render. This prevents rain absorption, sheds dirt, and allows the masonry to breathe.
How do you handle window sills on Ashbourne house wraps?+
Applying 100mm–150mm of external insulation extends the outer wall line beyond standard concrete window sills. We install bespoke powder-coated aluminium window sills fabricated by our sister company, Cills.ie, located in our Inchicore depot. Each sill has welded watertight upstands, thermal separation tape, and extended drip edges to ensure water discharges cleanly clear of the new facade.
Can I qualify for an SEAI grant if I already have cavity bead insulation?+
Yes. Under the updated SEAI 2026 'second wall measure' regulations, Ashbourne homeowners who previously claimed a cavity bead injection grant can now claim the full €6,000 (semi-d) or €8,000 (detached) external wall insulation grant to bring their home envelope to modern A/B energy ratings.
