ICF (Insulated Concrete Forms) is a building method where hollow forms made of Expanded Polystyrene (EPS) are stacked, reinforced with steel rebar, and filled with concrete. The result is a monolithic reinforced concrete structure wrapped in continuous insulation on both sides. ### NUDURA's 6-in-1 System A single NUDURA form provides: 1. **Formwork** — holds concrete during pour 2. **Structural wall** — reinforced concrete core 3. **Thermal insulation** — 67mm EPS on each side (R-23.59) 4. **Air barrier** — continuous airtight envelope 5. **Vapor control layer** — moisture management 6. **Attachment strips** — built-in fastening points for finishes --- ## Performance Specifications ### Thermal Performance - R-value: R-23.59 (among the highest of any wall system) - U-value: As low as 0.11 W/m²K (Plus+ Series) - Energy savings: Up to 72% reduction in heating and cooling costs - Continuous insulation with zero thermal bridges - Heat transfer formula: Q = U × A × ΔT - Comparison: Standard concrete blocks U ≈ 2.3 W/m²K vs NUDURA U ≈ 0.45 W/m²K (5x better) - Blocks R-value ≈ 2.5 vs NUDURA R-23.59 (9x better insulation) ### Thermal Mass Advantage - Unlike exposed concrete blocks that absorb heat during the day and radiate it inward at night, NUDURA's concrete core is encapsulated within insulation - In summer: dual-sided insulation blocks external heat; concrete core maintains coolness - In winter: insulation prevents heat loss; concrete core stores and gradually releases warmth - Result: Stable indoor temperature of 21-23°C year-round - Blocks cause temperature swings of 15-32°C requiring constant HVAC - Conclusion: Thermal mass is only beneficial when wrapped in insulation. Exposed blocks = thermal mass working against you. NUDURA = thermal mass working for you - Detailed comparison: https://ecobuild.co.il/thermal-mass ### Fire Resistance - 4-hour fire rating - Concrete core protected by EPS layers that do not support flame spread ### Acoustic Insulation - STC 50+ (Sound Transmission Class) - Blocks background noise, traffic, and external speech ### Wind Resistance - Tested up to 402 km/h (extreme hurricane conditions) - Proven in "The Last House Standing" — an ICF structure that survived a hurricane while all surrounding homes were destroyed ### Blast Resistance (U.S. Military Test) - Official blast test at USMC Quantico base (2003) - ICF walls survived detonation of 50 lbs (22.7 kg) military-grade TNT from only 1.8 meters - Military TNT is significantly more powerful than commercial TNT - No fragment penetration recorded — wall remained intact and protective - Result: ICF wall is 2x stronger than Israeli mamad (safe room) - The entire ICF home functions as a protected space — 24/7 protection - The U.S. military already builds with ICF on military bases (Schofield Barracks, Hawaii) - Relevance for Israel: While Israeli construction includes one safe room per apartment, ICF construction makes the entire home a safe room ### Seismic Resistance - Withstands 8.0+ Richter earthquakes - Monolithic structure — single continuous reinforced concrete unit - Highly relevant for Israel (located on the Syrian-African Rift) ### EUCENTRE Seismic Research (2024-2025) - Report ID: EUC062/2024E, September 2025, 363 pages in 5 parts - Conducted by EUCENTRE Foundation / ShakeLab, Italy — one of the world's leading seismic engineering research institutes - Commissioned by Ecobuild System Ltd. and TREMCO CPG Italy / Nudura Corporation - One of the most comprehensive seismic studies ever conducted on ICF systems - Tested 6 full-scale wall specimen types under cyclic loading: - Type A: Conventional RC wall (shear-critical control) - Type B: ICF wall with identical section and reinforcement to Type A - Type C: ICF wall with reduced reinforcement (shear-critical) - Type D: Conventional RC wall (flexure-critical control) - Type E: ICF wall with identical section to Type D - Type F: ICF wall with reduced reinforcement (flexure-critical) - Key finding: ICF walls are at least as seismically resistant as conventional concrete walls, and in most cases perform better in terms of post-event damage - Identical initial stiffness, load capacity, and response parameters - Materials: B450C steel, C28/35 concrete - Engineering significance: The EPS formwork of the ICF system does not impair structural performance — the wall behaves exactly like regular reinforced concrete with all additional benefits - Full report available: https://ecobuild.co.il/docs/TREMCO_Experimental_Report_Part1.pdf through Part5.pdf ### Technion Product File - 101-page comprehensive product file submitted to the Technion for high-rise ICF construction approval -

ICF walls are 6x stronger than conventional block construction and 2x stronger than an Israeli mamad (safe room). **Can ICF replace a mamad (safe room)?** Yes. ICF construction, especially with the One Series or as a complete structure, can provide protection exceeding that of a standard mamad. The US military already builds with ICF on military bases. **How fast is ICF construction?** 2-3x faster than conventional methods. It combines 6 construction stages into one and requires less labor. **What about thermal performance?** NUDURA provides R-23.59 insulation with zero thermal bridges, maintaining stable indoor temperatures of 21-23°C year-round while saving up to 72% on energy costs. **Is ICF suitable for Israel's climate?** Absolutely. ICF is suitable for all climates — desert, coastal, mountainous. It's resistant to extreme winds, earthquakes, and soil salinity. **What finishes can be applied?** Any standard finish: stone, plaster, exterior panels, brick, metal. No special plaster is required. --- ## Site Map (Key URLs) - Homepage: https://ecobuild.co.il/ - ICF Method: https://ecobuild.co.il/icf-method - Products: https://ecobuild.co.il/products - DWG Library: https://ecobuild.co.il/library - Knowledge Center: https://ecobuild.co.il/knowledge - Blog: https://ecobuild.co.il/blog - Academy: https://ecobuild.co.il/academy - Tutorials: https://ecobuild.co.il/academy/tutorials - Green Building: https://ecobuild.co.il/green-building - Seismic Building: https://ecobuild.co.il/seismic-building - Net Zero: https://ecobuild.co.il/net-zero - Thermal Mass: https://ecobuild.co.il/thermal-mass - Energy Calculator: https://ecobuild.co.il/energy-calculator - Quote Calculator: https://ecobuild.co.il/quote-calculator - Compare Methods: https://ecobuild.co.il/compare - Guides: https://ecobuild.co.il/guide - Q&A: https://ecobuild.co.il/answers - Standards: https://ecobuild.co.il/standards - Press: https://ecobuild.co.il/press - Media: https://ecobuild.co.il/media - Projects: https://ecobuild.co.il/projects - Gallery: https://ecobuild.co.il/gallery - Contractors: https://ecobuild.co.il/contractors - Contact: https://ecobuild.co.il/contact --- *This document is maintained by Ecobuild Israel.
