Tystø

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.

Waste-based module system
We make the partitions to your specified dimensions and needs. Each project gets a unique look as the modules are defined by the width of the available windows and your specified wall heights.

The wooden spacers makes the modules highly adaptable to both your dimensions and the available waste glass. See some examples in the illustration and reach out to see what we could deliver to your project.
Modular and designed for disassembly

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.

*Based on verified EPD calculations. Including phases A1-A5, C1-C4, D

1 Demolition

Windows are being sourced from buildings that are about to be demolished

2 Glass preparation

Windows from demolitions are carefully taken out and the IGU removed, cleaned and stored for manufacture

3 Manufacturing

The wood is cut to length for manufacture of the modules. The IGU’s are placed on rubber bands to make a tight fit

4 Installation

The modules are installed by DEKO on site. The modules are screwed together and can be taken apart and moved later in their lifespan

What happens to glass waste in Denmark?

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.

Doors & handles
Glass door
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.
Stainless steel
The door modules are detailed with stainless steel hardware for longevity and versatility.
Unique characteristics of Tystø
Knotty pine
Telling the story of waste, the wooden structure features harmless and beautiful knots.
Matte surface
The waterborne wax gives a matte surface that’s easy to maintain.
Silver spacer
If IGUs, the waste glass has silver spacers. Monolith is single glass, without spacer.
Glass imperfections
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 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.

Tender description 
Description text, private developer
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. 

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?

Module width will typically be approx. 1m. For very slim modules the price will go up as for other partitioning systems. Maximum height will be around 3,5 meters but reach out maybe we can find a solution together.
What parameters determine the price?
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.
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?
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?
No, the frames will always be made from discarded pine wood. We can supply the frames painted black so that the wall better matches other walls in your project.
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.
