In 2002 the first tested and certified passive house door in PVC with and without isolation glass has been developed in cooperation with REHAU. The Passive House test facility in Darmstadt has further successfully tested and certified the combination with REHAU Geneo and one-side-attachment-panel by Güwa. The manufacturers of PVC and aluminium front doors are offered a very high insulation with up to 0,28 for the attachment-panels by Güwa. In addition the single-sided attachment-panel in the standard version by Güwa has been successfully tested and certified for burglar resistance class RC 2 with other profile systems. For the sound insulation various certified sound insulation packages with up to 42 dB are offered.
