Homes built using an insulating concrete form (ICF) system literally have the insulation built into the walls as part of the structure. This system creates walls that have a high thermal resistance, with R-values typically above R-17. Even though ICF homes are constructed using concrete, they look just like traditional stick-built homes.
One of the most important advantages of concrete is its workable, viscous state that allows it to be formed into literally any solid shape. Concrete Forming refers to the temporary or permanent support structures used to contain concrete as it is poured and while it hardens. Formwork can be made of many different materials, and it can be removed after the concrete is set or remain in place permanently. One may utilize formwork that moves either vertically or horizontally (slip form paving) to allow extrusion and finishing of the concrete. Form liners and architectural form details can also be added to the basic structural formwork to create designs and patterns in the concrete for use as a decorative finish surface.
