ICF Wall System

Insulated Concrete Formwork

What is IntegraSpec 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 IntegraSpec ICF work?
On site, IntegraSpec 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.

ICF - Insulated Concrete Formwork
  • It's easy - experienced installers can achieve up to 4m2 per hour, with minimal mechanical equipment and power tools required
  • It's quick - the building can be watertight in less time, and supporting trades can get on site swiftly
  • It's robust - designed to withstand the pressures of wet concrete pours of up to 3m
  • It's designer-friendly - ideal for innovative or unusual design features, including curved walls and freeform shapes
  • It's flexible - variable size webs and our unique H clip allows total core size flexibility; we've already used it to create walls over 1m thick!
  • It's easy to clad - inserts are moulded into each panel to allow easy mechanical fixing of a wide range of exterior cladding, including stone, brick or rendering. Or choose our unique 'exposed concrete face' option
  • It's cheap to transport - save fuel with up to 1,000m2 of panel loaded in one truck
  • It's easy to store - our unique independent panel design reduces storage space compared to fixed block ICF
  • It's energy efficient - the great insulation properties of polystyrene and our unique cavity closers around windows and doors create a comfortable living environment all year round, keeping energy bills low
  • It absorbs sound - the formwork is an efficient sound absorption system; great for acoustic performance and reducing noise from adjoining properties
  • It's made in the UK! - supporting British jobs, and ensuring the quickest possible turnaround time from initial order to delivery on site
