The highest-performance, most eco-conscious closed cell foam available. Fourth-generation HFO technology delivers maximum R-value, structural strength, and a complete vapor barrier - with 80% less environmental impact than legacy foam.
Closed cell spray foam - also called two-pound foam - is a high-density polyurethane foam made up of completely closed cells. The tightly packed structure creates one of the most effective thermal and moisture barriers available in the insulation market.
When sprayed, it expands and adheres to virtually any surface - concrete, metal, stone, wood - forming a rigid, airtight seal. The EPA estimates proper insulation and air sealing can save up to 20% on monthly energy bills.
Projects requiring the highest thermal performance, moisture control, or structural enhancement. The go-to choice for roofing, below-grade applications, metal buildings, and any space exposed to extreme conditions.
HFO (Hydrofluoroolefin) refers to the blowing agent used to expand the foam during application. It is the fourth generation of spray foam technology, replacing the older HFC compounds that have been phased out in the US since 2021.
HFO compounds - made from hydrogen, fluorine, and carbon - carry 80% lower Global Warming Potential than their HFC predecessors, with zero ozone depletion potential. Same premium closed cell performance. Dramatically cleaner chemistry.
Any project that demands the full performance of closed cell foam - and a cleaner environmental profile. HFO is especially relevant for:
