ICFs are composed of expanded polystyrene foam (EPS) and polypropylene plastic. EPS foam is highly efficient and durable for insulation purposes. The polypropylene plastic webs are molded to accommodate rebar placement, provide embedded studs for attachments, and offer strength to resist concrete pressure during pouring, ensuring the panels remain intact throughout the process.

Energy efficiency in heating and air conditioning systems is measured using British thermal units per hour (BTUh). Air conditioners extract heat from homes in BTUs, while cooling and heating capacities are expressed in BTUh. For reference, one ton of cooling is equivalent to 12,000 BTUh.

The heating seasonal performance factor (HSPF) is a measure of heat pump efficiency. It represents the ratio of heat output to electricity consumption over an average heating season. A higher HSPF indicates greater energy efficiency in the heat pump's operation.

We recommend that consumers conduct their own research to form independent conclusions.
