BMB Timber Windows and Doors



Our non-compromising Lift & Slide zero threshold balcony door system is for achieving the maximum amount of light ingress to your property. With the unique fitting system by GRETSCH-UNITAS, we are able to produce sliding balcony doors with a width of up to 18 meters and a maximum height of 2.7 m. Despite such large dimensions, the Lift slide door leaf opens and closes very easily.

The specially designed "warm" aluminium profile which is the threshold of the Lift Slide system makes it possible to achieve a flush threshold from the inside to the outside of your property.
