*CO₂e footprint is based on Tystø EPD including phases A1–A3 and C1–C4. Phase B and D excluded. Comparison is based on average available EPD data on virgin glass partitions as of May 2025. Declared unit for all compared EPDs: 1 m² of partition wall. The glass in the virgin walls has a thickness of 12–12.8 mm and hence a similar dB reduction. The discarded glass used for the Tystø wall will have a varying thickness depending on the input source, which means that the Tystø wall will have a different dB reduction from case to case.

Fire
Tystø is not fire tested. Due to the variable nature of demolition glass supply, fire classification cannot be guaranteed. When needed Tystø integrates seamlessly with DEKO Tré where fire zoning is required.
Application
Tystø is suitable for:
- Meeting rooms
- Cellular offices
- Interior zoning where fire classification is not required
Tystø is typically combined with DEKO Tré in projects where fire-separating walls are needed. This allows architects and developers to apply Tystø where transparency and material storytelling are desired, while meeting regulatory fire requirements elsewhere.
Acoustic Performance
Tystø's sound insulation values range between
31–39 dB
Tystø’s acoustic performance reflects the original specifications of the reclaimed glass units. Typical combined sound insulation values range between 31–39 dB, depending on glass composition and wall coverage
- Suitable for standard office environments
- Not intended for spaces with strict acoustic separation requirements
- Acoustic performance is communicated transparently during early project phases to ensure correct placement and expectation management
Cellular Offices
Cellular Offices
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.
Glass composition (mm) | Combined sound insulation (db) |
10 | 35 |
12 | 39 |
24 (4-16-4) | 34 |
26 (6-16-4) | 37 |

Unique Characteristics
Unique Characteristics
Knotty pine
Telling the story of the materials origin, the wooden structure of Tystø features natural, harmless and beautiful knots and other imperfections that we wish to highlight rather than discard.
Glass imperfections
Tystø’s waste glass can have smaller scratches and signs from its previous life, not impacting performance but showcasing it is entering its second stage of use.
CO2e Footprint Calculator
Calculate the real impact of your next project
Use the CO₂e Footprint Calculator to estimate how much discarded material you prevent, and how much CO₂e you save, when choosing Tystø glass partitioning walls instead of conventional partition systems. This helps you document sustainability benefits in tenders, DGNB submissions, and client presentations.
Tystø keeps glass at a high functional level by:
- Recovering glass units from Danish demolition projects
- Avoiding energy-intensive remelting processes
- Designing modules that respect original glass dimensions
This results in:
- Significant waste reduction per m²
- Lower CO₂e emissions compared to virgin flat glass
- Full traceability and documentation for project reporting
1. Dismantling & glass preparation
Exterior windows, and glass from interior partition walls are carefully removed from buildings undergoing renovation or demolition.
2. Sorting & ID tagging
The IGUs from windows or partition walls are cleaned, tagged, and stored for manufacturing.
3. Digital arragement
Using digital tools, the IGUs are arranged in patterns to maximize utility and achieve the desired design.
4. Assembly
Wooden profiles, made from off-cuts, is cut to size for the production of modules where the discarded glass is placed and secured.
5. Installation
The modules are installed on-site by DEKO.
6. Demounting
When a building is renovated or demolished, Tystø is designed for easy disassembly and can seamlessly enter our take-back system for reuse.

FAQS
Frequently Asked Questions
General
Covers acoustic performance (dB values based on harvested glass units), typical module dimensions and height possibilities, and the key parameters that influence pricing. Including doors, customisation, and site conditions.
What are the acoustic properties of the walls? Do you offer sound testing at site after installation?
What are the acoustic properties of the walls? Do you offer sound testing at site after installation?
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?
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.
What parameters determine the price?
What parameters determine the price?
Number of doors, any special customisation, and the Installation site accessibility (stairs etc.) affect the square meter price.
Installation
Explains where Tystø can be mounted, how available glass units influence module width, and how the system integrates into standard interior partition applications.
Where can Tystø be mounted?
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.
Customisation
Describes the possibility of building modules from your own demolition glass, clarifies layout flexibility based on available stock, and outlines frame material options and finish possibilities.
Is it possible to have the product made with my own demolition glass?
Is it possible to have the product made with my own demolition glass?
Yes, we can deliver partitioning modules that matches your own glass units. In that case the customer supplies the measurements of the glass units and take the full responsibility of the glass units including storage. We will gladly help you mount the wall.
Can I design my own layout?
Can I design my own layout?
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.
Can I have alu frames instead of wood or another wood type than pine?
Can I have alu frames instead of wood or another wood type than pine?
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.
Disassembly
Describes how Tystø is designed for easy maintenance and future reuse, with glass units that can be separated and reused in new walls.
Is Tystø designed for disassembly?
Is Tystø designed for disassembly?
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.
