REHAU makes a number of contributions to the effective use of precious energy resources. This manifests as efficient products, innovative materials and resource-conserving production methods. REHAU continuously develops and refines energy-efficient system solutions for nearly every area of daily life: for substantial weight reductions in automotive and aircraft design, for reducing energy consumption in supermarkets and public facilities as well as for minimizing energy losses in private living spaces.

Whether you're building or renovating, modern window and door profiles made of polymers or composites make a major contribution to preventing energy losses. Innovative surface-heating and -cooling systems in floors and concrete walls enable sustainable and efficient use of energy – particularly in combination with environmentally sound geothermal energy extraction. We develop our solutions together with partners in a wide variety of industries to ensure that they function efficiently and for the good of the environment.
