GU system threshold

Comfort, security, quality

Energy-efficient installation of doors and balcony-doors can be achieved using the CE-certified, thermally-broken Gretsch-Unitas door thresholds. The thermal break increases living comfort, as moisture formation in the interior is prevented by constructional design measures. The GU system threshold, including accessories, is available to match different profile systems in the house entrance door and balcony door range so that the fabricators can efficiently install the thresholds in their systems. The GU system thresholds are CE-certified with various system profiles.

Thanks to the great number of available depths, the GU system threshold is suitable for almost every installation situation in new buildings and renovation projects.
