Good indoor climate
Uniform and efficient air distribution without drafts
Uniform air distribution ensures good indoor climate
Textile based ventilation
KE Fibertec AS develops, manufactures and markets good indoor climate or air distribution systems based on fibre technology and sustainability. The principle is that the ventilation air is distributed draft-free and uniformly through the customised textile ducts.
Today, KE Fibertec air distribution systems are used in almost all types of installations - from industrial applications to sports halls, office environments, laboratories, the food sector and many other places where a good indoor climate is needed.
The world’s first Cradle to Cradle certified ventilation duct
In 2012, KE Fibertec had CradleVent® approved as the world’s first Cradle to Cradle certified ventilation duct.
CradleVent® is the world’s first ventilation duct that approved as a Cradle to Cradle certified product by the renowned organisation EPEA in Hamburg. CradleVent® is our example of a future-proof and sustainable product for air distribution in offices, schools, laboratories, sports halls, public buildings and other comfort environments.
The increasing demands on contractors and architects for sustainability and resource efficiency make it attractive to include CradleVent® as a proven component in construction.

A solution designed for the room
Designed for the layout of the room
Sometimes a ventilation system can be a challenge to fit in with the rest of the interior design of a room. This could be rooms with curved walls, limited ceiling space or projects where the solution can be made almost invisible along the ceiling.
One of the many advantages of textile based ventilation is the flexible material that can be tailored to the customer’s needs. With three variants of round, half-round and quarter-round ducts, we can design the solution to fit into the architecture, depending on the need for air exchange.
When permeability is essential
KE Fibertec develops and markets three main product groups for TBV, all of which are available in three different geometries. In the passive low impulse systems the air diffuses out through an air-permeable material. In high impulse systems, the air is distributed exclusively through holes (KE-Inject System) or nozzles (KE-DireJet System). The hybrid versions are a combination of the passive low impulse systems and the laser-cut Inject holes or DireJet nozzles.
3D visualisation of your solution
TBV Designer
Flexibility and customised products are what characterise our TBV solutions. Here you are free to choose the dimension that best fits the design instead of being bound by a certain number of standard solutions.
In addition, we offer endless choices of system layouts, colours, offsets, bends, sockets, materials and, not least, whether the TBV system should be passive (low impulse), semi-active (hybrid) or fully active (high impulse).
We offer a wide range of standard colours and, for an additional cost, our textiles can be dyed in custom colours to match the interior.
3D design programme
To dimension our textile duct solutions, we use the advanced 3D programme TBV Designer. We dimension your solution with desired air velocity and room dimensions and design a system that is customised to meet the ventilation needs of the room.
Advanced programme
Based on our many years of experience and extensive technical knowledge in textile based ventilation, we have developed the TBV Designer programme from the ground up and continuously improved it so that it is always based on the latest technology.
The system allows you to visualise the solution and provides you with data such as thermal air velocities in the occupied zone, pressure loss, sound data and carbon footprint calculation.
Complete CO2 documentation
We have further developed our TBV Designer to include the total footprint for each project. Where others have prepared EPD documentation for parts of a solution, our EPD material is complete because it provides full insight into all footprints.
With calculations for all components from textile materials, mounting parts, accessories and packaging, you get product-specific CO2 data that makes it easy to choose our textile based ventilation solution.
By choosing a textile based ventilation solution, you achieve 4-5 times lower carbon footprint compared to an identical solution using steel ducts*.

• System pressure loss
• Pressure loss in substrings
• Sound data
• Climate footprint calculation
• Thermal penetration lengths

Materials and knowledge that make the difference
Own weaving mill
KE Fibertec is the only manufacturer of textile ducts in the world with its own weaving mill. The weaving mill was founded in 1972 and is today run by the third generation of the family business.
KE Fibertec Weaving Mill only makes textiles for duct ventilation, which is unique in the world market and gives us a very special knowledge of the materials that can benefit our customers.
KE Fibertec Weaving Mill has very strict yarn supplier requirements, and the raw materials must go through an extensive incoming inspection to ensure that the air permeability is the same wash after wash. A barcode follows the fabric, giving us full traceability in terms of production date, permeability, etc. from yarn cone to finished product installed at the customer.
Fire approved materials
All KE Fibertec materials are of course fire approved according to DS 428 (article 3.8.): ”Air distribution ducts (such as textile ducts) must be made of materials that fulfil the requirements for material class B-s1-d0. However, up to 5% surface area of plastic nozzles etc. of material class F may be built in, provided it is surrounded by material of class B-s1-d0.”
Choose from unique materials and colours
We are the only manufacturer in the world to offer customised textiles from our own weaving mill. Our materials are developed exclusively for air distribution and not for tents or awnings when it comes to uniform airflow, shrinkage after washing, colour fastness and, not least, maximum dust holding capacity. Our textile materials are also available in a wide range of colours, with our two main materials being Cradle to Cradle approved.

Washing and maintenance
A ventilation duct must be maintained in order for it to maintain its performance and thus be energy-efficient. This applies to both textile ducts and steel ducts.
Ensure a healthy indoor climate
The ventilation ducts will become dirty over time, and dust will be deposited in ducts, on dampers and valves. Dust, dirt and, in the worst-case scenario, microorganisms in the ventilation system will reduce its efficiency and may, in some cases, be directly harmful to people’s health.
To ensure a healthy indoor climate and the best possible energy efficiency, it is therefore important to regularly inspect ducts, dampers, valves and filters in the ventilation system.
The textile duct can be easily dismantled and washed as required. Our processed Trevira CS materials absorb max. 1% water even at a relative humidity of more than 90% and the materials are approved for the food industry.
Antibacterial treatment
In extremely humid environments we recommend an additional Antibac treatment of the materials that renders them resistant towards fungi and microorganisms. Please note that the effect is non-existing at rates below 85% RF.
Extend product life
Washing and maintenance costs must be included in the design as early as in the project planning phase. It is a mistaken belief that you can choose ”maintenance-free components” like some suppliers claim, because they do not exist.
With correct maintenance and regular washing of the textile ducts it is possible to save energy and extend the life of the product.
We follow the UN Global Goals
Since 2021, the 17 Sustainable Development Goals of the UN have been a central part of our approach to sustainability. We have selected four specific goals that we are working towards.
Working with external advisors has provided us with valuable input and challenged us in relevant areas. This has enabled us to make strategic choices that not only strengthen our sustainable profile, but also contribute to concrete improvements and support our continued growth.
By continuously evaluating and developing our work based on the global goals, we ensure that sustainability remains an integral part of our business. It also means that we constantly focus on where we can strengthen our efforts – both in our internal processes and in the solutions we offer our customers.
Our products and processes meet a range of requirements within the construction industry and document that our solutions make a real difference to the climate. This is part of our belief that responsible development and green choices must be incorporated into the entire value chain.
