Insulated concrete formers (ICFs), also known as building blocks, are a formwork system for reinforced concrete made from expanded polystyrene (EPS). They serve as permanent insulated shuttering, making them suitable for industrial, commercial, and housing projects.
ICFs originated in Germany 40 years ago and are widely used in Europe, the USA, Canada, and parts of South America. Isolite, a manufacturer since 1993, offers three ICF sizes: 1200 x 300 x 120 mm, 1200 x 300 x 150 mm, and 1200 x 300 x 180 mm.
The Isowall Group has been manufacturing and distributing Isolite Shape Moulded EPS since 1992. Isolite Shape Moulded EPS Products are manufactured using customised moulds providing a wide range of uses including insulation, lightweight fillers and semi-rigid cushioning.
Using EPS ICFs in construction is gaining popularity for its ability to expedite erection, cut costs, resist water, and provide superior thermal insulation compared to traditional brick and block methods. This enhances living conditions and lowers heating and cooling expenses.
The installation process is straightforward: stack the ICFs and fill them with concrete and rebar. This simplicity accelerates construction, eliminating the need for skilled bricklayers, as unskilled labor can be trained within days.
