Dunboyne 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 Dunboyne Estates & Commuter Homes
Located directly along the M3 commuter spine, Dunboyne homes have prime insulation potential to reduce ongoing heating costs and boost property value.
1990s 3- and 4-bed semi-detached houses with hollow concrete blockwork. External insulation seals heat into the structural walls and stops cold drafts through exposed gables.
Mature 1980s homes with uninsulated concrete blocks. Wrapping with Baumit graphite EPS eliminates condensation and upgrades energy performance from E/D to B1/A3.
Detached family residences and dormer properties. Wrapping four exposed facades with Baumit SilikonTop silicone render provides full thermal insulation and self-cleaning exterior protection.

Common questions from Dunboyne homeowners
How much does external wall insulation cost in Dunboyne 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 Dunboyne from your Inchicore depot?+
Our operations base and fabrication workshop are located at Unit 20, Westlink Industrial Estate, Kylemore Road, Inchicore, Dublin 10 (D10 TD35). Taking the M50 and M3 / N3 corridor, our installation crews and delivery vehicles reach Dunboyne in only 18 to 22 minutes, allowing rapid daily site supervision and material delivery.
Why is external wall insulation popular on 1980s and 1990s Dunboyne homes?+
Suburban developments in Dunboyne often feature 100mm cavity block walls or 215mm solid/hollow concrete blockwork with high thermal transmittance. Cold air penetrates through exposed gables and around window reveals, leading to condensation and high heating costs. Our Baumit graphite EPS wrap stops thermal bridging across 100% of the exterior wall surface.
Do I need planning permission for external wall insulation in Dunboyne?+
For standard residential housing across Dunboyne estates, external insulation is classified as Exempted Development under Section 4(1)(h) of the Planning and Development Act 2000. For properties listed as Protected Structures or located in village core conservation areas, planning consultation with Meath County Council is recommended. We confirm planning exemption status during our survey.
How do you handle window sills on Dunboyne house wraps?+
Because 100mm–150mm insulation extends beyond existing window sills, we install bespoke powder-coated aluminium window sills fabricated by our sister workshop, Cills.ie. Each sill includes welded watertight upstands, thermal separation tape, and extended drip edges to protect the new render facade from staining.
Can I qualify for an SEAI grant if I already received a cavity bead grant?+
Yes. Under the SEAI 2026 'second wall measure' rules, Dunboyne homeowners who previously had cavity bead insulation pumped into their walls are fully eligible to claim the €6,000 to €8,000 external wall insulation grant to reach A-rated thermal efficiency.
