KLIMA-PUR - Low Carbon Footprint bio-Polyurethane framing material for highly energy-efficient windows and doors

KLIMA-PUR is a new top-class framing material for highly energy-efficient windows & doors. This solution will reduce by 20% the direct CO2 emission associated with the building's energy consumption, responsible for 28% of total CO2 emissions worldwide. KLIMA-PUR circularity, extended lifespan of 35-45 years, repairability and low maintenance, as well as its easiness to recycle and recyclability content, is the result of a simple but resource- and energy-efficient design. Thanks to the utilisation of bio-Polyurethane foam as single material, this solution is highly functional while being highly thermal & acoustic insulating. KLIMA-PUR windows allow to reduce up to 50% the energy consumption and associated occupant’s bill for space heating and cooling of buildings and houses. Available in any color and finishing, KLIMA-PUR windows are a sustainable option for energy renovation activities toward a greener construction industry and a healthier planet.
