Glass Wall Partitioning
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 an interior partition wall made from demolition glass.”
We create partitions tailored to your specified dimensions and requirements. Each project achieves a unique appearance, as the modules are determined by the width of the available glass units and your specified wall dimensions.
The wooden spacers at the bottom and sides make the system highly adaptable to your project’s wall dimensions and the available waste glass. Explore some examples in the illustration, and feel free to contact us to discuss what we could deliver to your next project.
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 that were previously used as façade windows or partition glass in their first lifecycle. These windows are carefully removed and disassembled during demolitions and renovations. The glass units have become redundant as either exterior windows or interior partitions, and are therefore discarded by the industry. In the Tystø partition wall, the glass is given a new life as indoor partitions, thereby replacing the conventional, heavily polluting virgin glass. Granulating and recycling the glass units would require furnaces running constantly with temperatures above 1600°C, resulting in significant emissions. Tystø utilises the existing dimensions of the glass units and designs the finished product with respect for their original form.
*Per m2, based on EPD, calculations for phases A1-A5, C1-C4. LCA calculations on window glass are based on input material counting as 0, as it is considered waste. Wooden window frame is calculated as virgin material
1 Demolition
The windows are recovered from buildings scheduled for demolition and from interior partition walls left over after renovations.
2 Glass preparation
Windows from demolitions and glass from former partition walls are carefully taken out and the IGU removed, cleaned and stored for manufacture
3 Manufacturing
The wood is cut to size for the production of the modules. The glass is placed on rubber bands to make a tight fit
4 Installation
The modules are installed on-site by DEKO. They are screwed together, but can be disassembled and relocated later in their lifespan.

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.

A wooden framed single glass unit. The frame is treated as the rest of Tystø.
Wooden door
Same frame as glass - lower emissions. It matches the rest of the spacer modules.
The door modules are detailed with stainless steel hardware for longevity and versatility.
Telling the story of its origin, the wooden structure features natural, harmless, and beautiful knots.
The waterborne wax gives a matte surface that’s easy to maintain.
If the wall is made from windows from demolition, the waste glass has silver spacers. Monolith is single glass without spacer.
The waste glass can have some smaller scratches and such from its previous life.
Sound performance and environmental impact are linked
When low C02 emissions is the target - it's important to know the impact of product 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 sound performance of Tystø has been calculated with Tystø covering 33% of total wall area, combined with one 48 dB concrete wall and two 48 dB gypsum walls. The data is based on sound testing conducted with various glass compositions.

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

For interior partition, a:gain Tystø partitions must be used in collaboration with DEKO.
The partition walls are industrially upcycled and consist of demolition glass and unsorted wood. Both waste sources are digitally controlled in the process, ensuring that: a) no hazardous substances are included, b) traceability is maintained, c) the glass used in dimensions and types fits a Tystø wall.
The product is marketed and sold by a:gain, while final measurements, production, and installation are carried out by DEKO. The product has an Environmental Product Declaration (EPD) which can be found on the EPD Denmark website.
Generic tender text, EU Tender Rules
For interior partition walls, a product that has emerged through industrial upcycling is desired, where production inputs are secondary raw materials, such as cut-offs, demolition materials, and waste from the construction industry and other industries.
The product must be delivered with an approved EPD, and the company must also be able to present EU Taxonomy Compliance 5.1 documents. The supplier must demonstrate that external sound tests of the system have been conducted through a so-called GTS institute. There must be an installation guide as well as an operation and maintenance manual for the product. Installation must be carried out by a specialised company with many years of experience
in the field.
For the sake of social sustainability and job creation in connection with the green transition, as well as minimal transport of materials, the glass and wood should come from the Danish market and be produced in Denmark.
So far, we can supply a DB glass value that is calculated from the composition of the glass units that we harvest. Reach out to find out what we have in stock. We do not offer sound testing at site after installation.
What module sizes are possible? Are there any dimension limitations?
Module width will typically be approx. 1m. For very slim modules the price will go up as for other partitioning systems in the market. Maximum height will be around 3,5 meters but reach out maybe we can find a solution together.
Number of doors, any special customisation, and the Installation site accessibility (stairs etc.) affect the square meter price.
Where can Tystø be mounted?
Basically, anywhere you would normally mount glass partitioning walls. The available glass units cannot be changed in size and hereby define the module width but the wall can fit in any giving whole.
No, you cannot design your own layout as the windows we have in stock vary over time. However, we’ll always include you in the design process and make sure we find a solution that you’re happy with.
No, the frames will always be made from discarded pine wood. We can supply the frames painted so that the wall better matches other surfaces in your project.
Yes, Tystø is truly designed for easy maintenance, repair and reduction of both present and future waste. The glass units can easily be disassembled from the wooden parts and reused in future glass walls.
