INDRESMAT is a chemical startup that develops bioPUR (bio-polyurethane) materials to improve the efficiency of the thermal envelope of buildings, with products such as profiles and frames for highly energy efficient windows & doors (KLIMA-PUR), as well as foams and insulation panels for walls, roof and floor with highly improved safety in case of fire (SAFE-PUR). In this way, INDRESMAT addresses 100% of the heat loss in the envelope, estimating a 70% reduction in energy demand related to heating and cooling activities of buildings and houses (the major emitters of global CO2).
