CoolFlux improves building materials at low cost.


CoolComposites is developing CoolFlux, a drop-in additive for polyurethane foam and other building materials that can cut AC use in half. A thermally-reversible inorganic phase-change material, CoolFlux is an integrated thermal battery. It absorbs heat during the day and releases it overnight, recharging itself for the next day. Meanwhile materials containing CoolFlux look, feel and install just like their traditional non-PCM-enhanced counterparts.
