Thermal insulation is becoming increasingly important. That is why ADORO doors bear the certificate of the authorised testing institute ift Rosenheim. Thanks to an extremely low heat transfer coefficient starting at just 0.49 W/mK, our doors are a natural choice even for low-energy houses. To achieve such excellent figures, we go well beyond the standard: Instead of the usual three or even only two sealing points, ADORO doors are sealed four times. And for our glass doors, we use triple or even quadruple thermal insulation glazing.
