The ICF Wall is the latest addition to the wall system.
As one travels around the United States nowadays, one often sees houses constructed using ordinary two-by-fours. Most typically, pine is used to build these walls. The stud walls are cut into to run plumbing and electricity through, loaded with insulation, sealed with vapour barriers, and then coated with sheetrock on the inside and a finishing appearance (possibly brick) on the exterior. These materials must be trimmed to size, causing waste and effort.
Insulated blocks for building less intense and wasteful ways of building new homes are gaining favour in the US. The walls of an ICF house are made out of foam blocks piled on top of each other rather than two by fours. A homeowner receives a steel-reinforced concrete wall with nearly 4 inches of EPF. The depression in the wall centre is filled with concrete after the appropriate form and height.
Plumbers and electricians can readily run pipes and cables. The precise measuring lines integrated into the foam panels make ICF concrete walls ideal for mounting drywall and siding.
The ICF foam block is not particularly strong on its own, but when piled (almost like Legos), it becomes a solid wall. As previously stated, concrete is poured into the centre. A wall built using ICFs is solid. A recent university test demonstrated that these barriers could survive 250 mph winds and bullets.
