NUDURA® Integrated Building Technology Insulated Concrete Forms (ICFs) are used as stay-in-place permanent formwork for structural concrete, loadbearing and non-loadbearing, below-grade and above-grade walls. The forms are used in construction of plain and reinforced concrete beams, lintels, exterior and interior walls, basement/cellar walls, foundation and retaining walls. The forms remain in place after placement and curing of concrete which is required by all Codes and Regulations to be protected by approved interior and exterior finish material. Subject to specific UK Regulations, the forms may also be used for applications requiring fire resistive construction, or non-combustible construction for buildings of any type, shape, height and any building area. Structures to 40 storeys achieveable.


  • Thermal comfort combined with thermal mass advantage yields potential energy savings for end use client of over 70% depending upon geographic location and fresh air ventilation requirements for occupancy type.
  • U values of 0.24, 0.18, 0.14, 0.11.
  • 17 Thermally Modelled Junctions calculated in accordance with EN ISO 10211_2007/BRE IP 1/06 & BR 497 with reference to EN ISO 6946/BRE 443 as well as per PHPP. Calculated y-value of between 0.025 - 0.03 achievable, dependent on design.
  • Sound attenuation of SRI 51 (minimum), for 152 mm core and above.
  • Air permeability tested as low as 0.5 m3/h.m2.
  • Fire resistive construction of up to 4 hours (ULC listed UL classified).
  • Reaction to Fire, Euroclass E as per EN13501-1:2007
  • Disaster safe occupancy – can be reinforced to sustain wind loads up to 250 mph (402 km/h).
  • Improved IAQ (Indoor Air Quality) as EPS foam does not propagate mould growth. No interstitial condensation.
  • BRE Green Guide Accredited A+ rating (100mm core) A rating (150mm core and above).
  • Full flexibility of cladding options available.
  • NHBC, LABC, Premier Guarantee approved.
  • CML (Council of Mortgage Lenders) approved.
