What is ICF?
Insulating Concrete Formwork (ICF) is an innovative, sustainable, high performance building system. Quite simply, it allows fast construction of creative, flexible buildings with low running costs and a long life.
How does ICF work?
On site, ICF expanded polystyrene panels are fixed together with webs made from high impact polystyrene plastic to create a formwork to which horizontal and vertical steel reinforcements can be easily added for extra strength. Once braced, the formwork is simply filled with concrete. The expanded polystyrene panels stay in place, resulting in a super-insulated monolithic solid concrete structure.

Where can ICF be used?
The flexibility of IICF means it works well for a wide variety of different building projects. It has already been successfully used in the construction of apartments and houses, care homes, commercial buildings, hospitals, hotels, schools, stables, hot tubs, swimming pools and basements. It’s no wonder ICF is already the first choice for high performance and sustainability with designers, installers and occupiers across the UK, Europe, America, Canada and Asia.
What's the thermal performance of IICF?
The thermal performance of any structure depends on two key measures - ‘thermal mass’ (the ability of the exterior envelope to store heat and release it over a 24-hour period) and ‘thermal storage’ (the ability of the building material to minimise
temperature fluctuations and stabilise internal conditions). With ICF, the thermal mass of the concrete combines with the expanded polystyrene insulation inside and out to help keep the structure warmer in winter and cooler in summer. Whatever the external temperature, the heat energy inside the building is continually conserved.
What are the U-values of ICF?
In the standard configuration, the ICF system can offer U-values down to 0.20w/m2k. By adding our unique expanded polystyrene inserts, U-values can be improved to around 0.10 w/m2k.
Does ICF prevent thermal bridging?
Following independent tests for thermal bridging prevention, ICF has been verified as the best in the UK, with a lower thermal bridge loss than any other building system.
What's the fire performance of ICF?
As concrete can’t be set on fire and doesn’t burn, the ICF system is very safe, providing an excellent level of protection against fire. Depending on the thickness of the concrete core, it can provide up to 3 hours of fire protection.
How green is the ICF system?
- Every element of the ICF system is geared towards energy efficiency, low waste and long life
- All our products are either made from recycled material or can be recycled
- Our expanded polystyrene is free from CFCs or HCFCs
- Up to 1,000m2 of panels can be loaded onto one truck, saving on fuel costs and reducing the carbon footprint.
- One standard panel size fits any wall, saving on storage space
- Buildings constructed using ICF exceed the energy efficiency requirements for current building regulations
