Natural daylight in winter, fresh air in summer – for the climbing hall in Böblingen, ALPGATE delivered a 9 x 6 metre glazed sliding-folding door. The standout feature: this approximately 3-tonne door was custom-made and installed precisely within the reveal of a load-bearing glulam structure. The result is a movable façade that emphasises the character of the timber construction and seamlessly connects the hall’s interior with the outdoors.
