Video from ICFbuildings on how to design and install ICF on an entire home.

This community of production homes in central New York state was built with insulated concrete forms (ICFs), which provide a highly insulated, airtight structure that is fire-, pest-, wind-, and earthquake-resistant.

Right – 11-inch ICFs provide R-50 of wall insulation from the footing to the roof on this cold-climate home.

The floor slab is completely insulated with ICF foundation walls and R-20 (3 inches) of closed-cell foam that is sprayed directly onto the ground before pouring the slab.

Right – Two inches of rigid foam was installed on the ground before pouring the basement floor slab while precast, pre-insulated concrete panels comprise the basement walls.

Between the ICF foundation walls, the builder sprayed closed-cell spray foam directly onto the gravel base to provide a vapor barrier and continuous layer of insulation under the slab.

Concrete is poured into the rigid foam shell of the insulated concrete form (ICF) walls; a plastic water barrier has already been installed to protect the below-grade wall surfaces.

The foundation walls are ICF block providing two continuous layers (R-23) of insulation around the slab, which will sit on an additional 4 inches (R-20) of low-VOC EPS foam.

Wiring runs are covered with canned spray foam to maintain the continuous foam layer that covers the inside and outside of these ICF block walls.

Seams in the ICF block are sealed so the EPS foam surface can serve as the drainage plane; no house wrap is needed.
