Hollow-block homes across Raheny, Artane & Harmonstown
Dublin 5 has one of Northside Dublin’s highest proportions of solid concrete and 9-inch hollow-core block semi-detached and terraced homes. These properties cannot be pumped with bead insulation because there is no continuous cavity void.
By mechanically anchoring and adhesively bonding 100mm Baumit EPS to the external masonry, the structural blockwork remains warm. Internal heat is retained, eliminating cold bedroom walls and cutting energy bills by up to 45%.
Dublin 5 properties benefit from Baumit SilikonTop silicone render, which prevents moisture from penetrating the masonry while remaining completely vapour-permeable, shedding grime and stopping algae growth.

External wall insulation questions in Dublin 5
How much does 100mm external wall insulation cost in Dublin 5?+
A standard 3-bed semi-detached home in Dublin 5 (Raheny, Artane, Harmonstown, Kilbarrack) typically ranges between €13,000 and €19,000 gross. With our direct SEAI grant deduction of €6,000, your net out-of-pocket investment is typically between €7,000 and €13,000. Mid-terrace homes range from €10,500 to €14,000 before the €3,500 grant (net €7,000 to €10,500), while detached houses receive €8,000 off.
Why is external wall insulation the best solution for Dublin 5 housing?+
Thousands of post-war and 1960s–1970s houses across Dublin 5 were built with 9-inch hollow-core concrete blocks or solid block masonry. These walls lack a cavity, making bead pumping impossible. 100mm Baumit external insulation wraps the cold masonry exterior, stops heat leakage, cures damp walls, and protects against coastal dampness without shrinking internal room sizes.
Do you supply and install replacement window sills in Dublin 5?+
Yes, 100%. When wrapping a home with 100mm of insulation, existing window sills lose their required projection. Our sister workshop Cills.ie manufactures bespoke powder-coated aluminium window sills with welded watertight end caps that drain rain safely past the new insulation.
Can I remain in my home during external insulation works in Dublin 5?+
Yes. 100% of installation work takes place on the exterior using scaffolding. There is zero dust or mess inside your home, no demolition of plasterboard, and no disruption to your daily heating, water, or electricity.
Who manages the SEAI grant paperwork in Dublin 5?+
Isotherm is an SEAI Registered Contractor (#10423). We handle the technical approval paperwork from start to finish and deduct the grant value directly from your invoice at source.
