Insulating Concrete Forms

Insulating concrete forms (ICFs) provide a labor-efficient means of making insulated poured-concrete walls. ICFs are permanent forms—they aren’t disassembled after the concrete has cured. Most of these products are made from expanded polystyrene (EPS) foam, which has a very low global warming potential (GWP); several are made from extruded polystyrene (XPS), which is currently blown using a high-GWP HFC blowing agent, and a few are a composite of wood waste or EPS beads and portland cement. Both EPS and XPS are produced from benzene, a known carcinogen) and both currently contain the brominated flame retardant HBCD, which is a persistent, bioaccumulative toxin. To protect against potential damage from wood-boring insects, some EPS foam used in ICFs contains low-toxicity borates.
