Partitioning wall system
Tystø is an indoor partitioning system made from used thermo glass units and discarded pine wood. Tystø uses a modular system and is designed for disassembly. We make the partitions to your specified dimensions and needs, meaning each project gets a unique look. Tystø is in collaboration with DEKO.

"I am made from demolition glass units turned into indoor wall partitionings"
The glass units are kept in place by a waste wood frame structure. Its pine profiles are made from window frame production discards. With its solid construction and wax finish, it’s modern yet traditional and of course designed for disassembly. It’s truly designed for easy maintenance, repair and reduction of both present and future waste.

Tystø is made from reclaimed glass units, which in their first life cycle have been used as facade windows. The windows are carefully taken out and disassembled in demolitions and renovations. The glass units are obsolete for exterior windows and thus discarded by the industry. However, they may live a long second life as indoor partitions, where they replace the conventional, heavily polluting virgin glass. Granulating and recycling the units would require furnaces running constantly with temperatures upwards 1600°C, leading to high emissions. With Tystø we embrace the glass units.

The same infrastructure as well as legislative framework is not currently in place for flat glass waste which hinders its reuse and recycling. The little glass from the built environment that is recycled is rarely recycled as flat glass; instead, after removal it is downcycled for use in insulation, containers, construction aggregates, and road paint, among others.

Sound performance and environmental impact are linked
When low C02 emissions is the target - it's important to know the impact of small decisions. With virgin glass products - specified sound requirements of a glass wall is directly linked to its CO2 emissions.
Tystø breaks this link
The reused glass units have the same low CO2 emissions no matter the sound performance. However, being 25 years old demolition glass, its sound performance reflects the standard of its time. Tystø glass in stock have a sound value of 31-39 DB. See below how different glass units can impact the room sound performance.
Small office room
The Tystø sound performance has been calculated with Tystø covering 33% of total wall area, with one 48DB concrete wall and two 48DB gypsum walls. The input is based on conducted sound testing in different glass compositions.

The Tystø sound performance has been calculated with Tystø covering 74% of total wall area, with one 48DB concrete wall and one 48DB gypsum wall. The input is based on conducted sound testing in different glass compositions.
