American Insulock makes insulating polyurethane concrete forms-Insulock Blocks-and the equipment used to manufacture them. Using polyurethane rather than polystyrene-the material " virtually every other manufacturer of insulating concrete forms" uses, produces much stronger blocks, the firm claims. These insulating blocks can be used "to construct soundwalls and buildings that are highly effective at absorbing sound and that have an R-30 or R-38 heat insulating value," American Insulock adds."
