ICF Construction in Dublin
Build your Dublin new home or extension with Insulated Concrete Forms (ICF). We pour monolithic, reinforced concrete structural walls encased in dual-layer EPS insulation to your structural engineer's drawings. Based at Unit 20, Westlink Industrial Estate, Kylemore Road, Inchicore, Dublin 10 (D10 TD35), our specialist crews build with Amvic, Nudura, Logix, and Quad-Lock systems across Dublin City and County.
Why Dublin self-builders & developers choose ICF
Insulated Concrete Formwork replaces traditional block laying with an airtight, structural concrete envelope that exceeds Irish Building Regulations Part L and Part A.
Dual EPS formwork layers eliminate thermal bridging at junctions, corners, and floor slabs. Walls achieve U-values between 0.11 and 0.15 W/m²K with negligible air infiltration (<0.6 ACH @ 50 Pa).
The monolithic concrete core absorbs sound energy dramatically better than lightweight timber frame or hollow block. Essential for Dublin urban infill sites near busy roads, railway lines, and flight corridors.
A 2-storey Dublin ICF home is erected, reinforced, and poured in 2 to 3 weeks. Rain does not stop wall assembly, allowing roof trusses and internal trades to proceed weeks ahead of traditional schedules.
ICF systems we install in Dublin
We install all certified ICF brands per your structural engineer's specification.
Amvic ICF
Irish-manufactured EPS interlocking blocks with high-strength polypropylene webs. Superb dimensional accuracy.
Nudura ICF
Large 2.4m folding forms with Duralok technology, providing ultra-fast installation on long wall runs.
Logix ICF
Platinum series graphite EPS forms delivering industry-leading thermal resistance and deep concrete core options.
Quad-Lock
Panel-based modular ICF system offering customizable insulation thicknesses from 100mm up to 300mm EPS.
Bespoke aluminium window sills by Cills.ie
Standard precast sills create massive cold bridges on deep ICF walls. We fabricate custom powder-coated aluminium window sills in our Inchicore workshop, engineered specifically for 300mm–400mm ICF reveals with welded watertight upstands and thermal isolation.
Common questions about ICF in Dublin
Why build with Insulated Concrete Form (ICF) in Dublin?+
ICF is ideal for Dublin new builds, urban infill sites, and modern extensions. It creates a monolithic reinforced concrete core encased in continuous EPS insulation on both sides. This delivers U-values as low as 0.11 to 0.15 W/m²K, extreme structural strength, airtightness exceeding Passivhaus standards, and acoustic damping (50+ dB sound reduction) that eliminates urban noise from Dublin traffic and flight paths.
Which ICF systems do Isotherm install in Dublin?+
We work with all certified ICF systems available in Ireland, including Amvic, Nudura, Logix, Quad-Lock, Fox Blocks, Beco, and Castleforms. We are not tied to any single manufacturer; we review your structural engineer's drawings and install the specified block system to exact tolerances.
How fast is ICF construction compared to traditional blockwork in Dublin?+
An ICF structural shell for a typical 200m² Dublin home can be erected and poured in just 2 to 3 weeks, compared to 8 to 12 weeks for traditional twin-leaf cavity blockwork. Because the insulation and structural walls are built in a single pass, follow-on trades (roofing, first-fix electrical, plumbing) can begin weeks earlier.
How do you manage urban infill and boundary walls with ICF in Dublin?+
Dublin infill sites often have tight site access, shared party walls, and strict boundary constraints. Lightweight EPS blocks are easily transported into restricted urban plots without heavy crane hire. Our bracing systems allow precise plumb alignment even when working adjacent to existing boundary walls.
How are window sills and external render detailed on Dublin ICF builds?+
ICF walls have a typical thickness of 300mm–400mm. Standard concrete window sills cannot safely bridge this depth without massive thermal bridging. We fit bespoke powder-coated aluminium window sills fabricated by our sister company, Cills.ie, located in our Inchicore workshop. For exterior facades, we apply NSAI-certified Baumit or Sto flexible silicone render systems with high-impact mesh.
How does the pricing and drawings review process work?+
Send us your architectural plans and structural engineer's drawings (PDF / CAD). We calculate exact wall surface areas, EPS block quantities, rebar reinforcement schedules, and concrete volume. We provide a comprehensive, transparent fixed-price quotation for supply, installation, bracing, and concrete pumping.
