Insulated Concrete Forms
Quality Work Guaranteed
Insulated Concrete Forms, better known as ICF, are becoming an increasingly common way to build homes.
They tend to be found in new construction versus in older buildings that have been renovated. This modern building material is usually made of blocks of polystyrene foam with space in between to pour a concrete wall. While this process is most commonly used for foundation walls, many contractors and construction companies are now taking ICF to the next level by using them for above-grade walls of one, two and three-story homes.
ICF blocks come in interlocking sections. Once installed, the wall system fits tightly together. When the blocks are in place, concrete is poured, then finishes like drywall and siding are attached to fastener strips embedded in the insulation.
The benefits of choosing ICF are many. It acts as an excellent insulator. Not only does it seal well, preventing air leakage through the walls … it also has two continuous insulation layers, one interior and one exterior, with no thermal bridges. This reduces heat loss in your building, making it very energy efficient. It can also provide greater comfort – maintaining consistent temperatures with no chilly draft coming through.
