The cross-sections of the façade columns are optimised in terms of material and structure to provide maximum openness, while fixing and sealing the glass without silicone or glue. The cross-module glazings are therefore only pressed onto the frames from the outside and sealed by means of dry gaskets.
The outer aluminum shells serve the weather protection of the wooden frame. These have been anodised in dark gray by the company Alumet in the interference process. This means that the dark hue is produced solely by the surface treatment and the associated refraction of light without additional dyes.
The glass panes themselves come from the company Glas Trösch. These are designed as 3-compartment thermal insulation glazing; they are partially pre-stressed and filled with argon. A sunscreen coating was dispensed in order to use solar gains within the unit. After being dismantled, the glasses can be mechanically separated from other components such as foils by companies such as Johann Schirmbeck GmbH, and returned to glass production.
In order to increase the thermal comfort, an external sun protection of the company Schenker Storen was installed, which reacts automatically to the respective sunlight and the resulting heat input. In the production of the blinds, a special, 100% recycled synthetic yarn was chosen in consultation with the manufacturer. All metal parts are screwed only.
The portal frame formed around the window front consists of three different types of copper sheet applied to a wooden substructure. It uses shiny, new copper, as well as various reused, already oxidized copper sheets to represent the entire copper recycling cycle. Some of the sheets were dismantled at a hotel in Austria and reused directly at UMAR.
