Premere Forms - Insulated Concrete Forms (ICF) are constructed from
a combination of rigid PVC, polystyrene foam, and polycarbonate components
creating a cavity into which rebar and concrete are placed.
Highly insulated concrete walls are formed using lightweight polystyrene
expanded or extruded foam. This polystyrene foam is combined with
Premere's patented corners, rails and cross-ties to create a concrete
form of foam insulation.
With rebar located at key points within the cavity and the forms
adequately braced, wet concrete is poured into the cavity. Once the
concrete sets, the polystyrene foam form remains in place to provide
insulation within the finished wall. This combination of concrete
and foam insulation creates a structure that has increased energy
efficiency, strength and overall durability.
