  • Efficient air distribution and good indoor climate

    Textile ducts are very well-suited for efficient, uniform, and draught-free distribution of fresh air without "dead zones". Stale and stagnant air may cause fatigue and headache. KE Fibertec's textile ducts create an effective air change and a good indoor climate in schools, offices, shops, showrooms, and other types of rooms where many people are assembled.

  • Flexibility and tailored solutions

    Flexibility and tailored designs characterize KE Fibertec's textile based ventilation (TBV) solutions. Here you may freely choose the size that fits the architecture of the building the best. Also you may choose from an almost unlimited range of system layouts, colours, materials, and whether the TBV system must be passive, hybrid, or active.

  • Unique materials and colours

    As the only manufacturer in the world we offer customized woven textiles from our own weaving mill. Our materials are designed for air distribution - not for tents or patio blinds when it comes to uniform air distribution, shrinkage after washing, colour-fastness, and not least best possible Dust Holding Capacity. We offer a wide range of standard colours and in addition to that our textiles may be dyed in any desired colour according to a standard colour system (at extra cost).

  • Fire approved materials

    Naturally, all KE Fibertec materials have been fire-tested and approved according to international fire standards incl. EN 13501-1.

  • Hygienic and easy to maintain

    All TBV systems are easily dismounted and washed in a washing machine. 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. In extremely humid environments we recommend an additional Antibac treatment of the materials that renders them resistant towards fungi and micro-organisms. Please note that the effect is non-existing at rates below 85% RF.

  • Excellent acoustic properties

    Our low impulse systems possess unique properties as to noise generation and if correctly dimensioned they can be used for sound studios without additional costs. At the same time the textiles act as sound baffles below the ceiling where they absorb and break down a part of the noise reflected.

  • No condensation problems

    All our low impulse and hybrid ducts (not coated materials) are made of permeable textiles where a little air will always diffuse through the surface. This prevents condensation problems on the surface, even in very humid rooms (>90% RH) thus rendering insulation unneccessary.

  • Easy to transport and install

    Our materials weigh 260 - 330 g/m2 which is much lighter than spiro ducts. At the same time textile ducts are much easier to handle and to transport as they are folded and packed in cartons of a maximum weight of 25 kg. KE Fibertec's suspension rails are delivered in exact lengths rendering installation easier and quicker than for similar systems.

  • Sustainable ventilation

    All KE Fibertec textile ducts are based on Oeko-Tex® Standard 100 certified yarns (12.0.03665). Our production is certified according to the ISO 14001 standard (Environmental Management System). Transportation and disposal of textile duct systems produce less CO2 pollutants than conventional steel ducts. CradleVent is the world's only Cradle to Cradle certified ventilation duct.

Materials

  • GreenWeave (low energy and sustainable material)

    GreenWeave is especially suited for comfort installations with high demands on indoor air quality. Typical applications are offices, schools, laboratories, conference centres, and cold work rooms in food industry.

    • Clean breathing air. GreenWeave filters the supply air as an M6 prefilter acc. to EN779:2012
    • Longer washing intervals with staple fibre yarns that ensure largest possible textile surface. GreenWeave has a dust holding capacity of 25 g/m² textile surface acc. to EN779:2012
    • No chemical additives. Green-Weave is made of 100% recycable material and is Cradle-to-Cradle certified
    • Fire tested acc. to EN13501 B-S1-d0 without any finishing treatment
    • Hygienic and washable material that does not condense
    • Optional antistatic feature

  • MultiWeave (durable and versatile material)

    MultiWeave is a multifunctional material that is highly suited for many different applications, from cleanroom facilities of ISO class 4, industrial facilities and sports halls to equalizing rooms in meat factories.

    • MultiWeave is made of multi-filament yarns with a plain surface structure. The filtration of the supply air is equivalent to that of a G2 prefilter acc. to EN779:2012
    • The material is cleanroom certified as class 4 acc. to ISO 14644-1 - no shedding of particles
    • Fire tested acc. to EN13501 B-S1-d0 without any finishing treatment
    • Highly durable material. Tear strength of 110- 210 N acc. to EN ISO 13937:2
    • Optional antimicrobial (Antibac) treatment for very humid envi-ronments (> 85% RH). The Anti-bac treatment may be harmful to the external environment

  • ZeroWeave (airtight material)

    ZeroWeave is an airtight, low-maintenance material with a wide range of application possibilities such as supermarkets, large sports arenas, swimming pools, high-bay industrial facilities, and rooms with high dust generation or limited accessibility.

    • ZeroWeave is an air tight material so the filter efficiency is zero. All the air is distributed through holes or nozzles
    • No PVC, halogens or other harmful substances. The material can be lasercut to improve the finished quality
    • Fire tested acc. to EN13501 B-S1-d0 without any finishing treatment
    • No condensation issues when used in environments below 90%  RH
    • Washing not needed in order to maintain functionality. Only for hygienic and aesthetic reasons

  • Nomex

    Nomex materials are made of high-temperature-resistant aromatic polyamide fibres which - equivalent to GreenWeave materials - are woven of staple fibre yarns, i.e. yarns that are spun of short thin fibres.

    The final yarn is made by twisting two yarns into one yarn that is used both in warp and weft direction (length- and crosswise of fabric). The result is a fabric that is capable of carrying a large amount of dust without blocking the air flow through the material. Such blocking would require washing of the textile duct to ensure the distribution of the calculated quantity of air at the calculated pressure loss.

    Similar to Trevira CS, Nomex materials are flame retardant, however, Nomex holds the extra feature of having a very high melting and self-ignition temperature. Nomex does not melt but decomposes at 370°C. Nomex materials for TBV are mostly applied in the shipping industry.

  • KE Fibertec weaving mill

    To ensure that KE Fibertec's stringent quality requirements are met, all its textile materials are woven at KE Fibertec's own textile mill. This allows us to ensure that the entire process from yarn to finished product has gone through our ISO 9001 quality assurance system.

    Our textile mill currently uses the latest technology, including state-of-the-art air-jet looms. This means that we are able, in collaboration with our development department, to develop new and better materials at any time, all for the benefit of the finished fabric's quality and of the end user, too.

    KE Fibertec uses only dyed and heat-treated yarns, which are heat fixed under constant supervision in order to achieve the most uniform and shrink-stable product possible. As a result, we are now able to offer the best guarantee on the market of maximum shrinkage of 0.5%.

    All the materials are also permeability-stabilised, which ensures the proper passage of air even after washing. This is absolutely crucial to the function of the textile ducts. For example, large variations in permeability will lead to excess consumption of energy if the material's weave is too tight or to pulsations around the inlet because the material's weave has become too loose.

Colours

We offer a wide selection of standard colours and with extra payment we can supply you with textile ducts in whatever colour you need, eg. according to the RAL colour system.

Why choose KE Fibertec as your ventilation partner?

Creating a good indoor climate involves more than just selling air distribution products. For KE Fibertec it's all about dialogue, expertise, reliability and logistics. We don't stock finished products or havestandard components. All our solutions are tailored to the task at hand.

No matter how much effort we put in, a good solution requires dialogue about the expectations of the end result. We offer our advice free of charge, so the sooner we are involved in the project, the betterthe chance we have of achieving a good result. Textile based ventilation (TBV) can replace more conventional air distribution fittings in almost every situation, but only if the design is tailored to the particular task.

If you are in doubt whether TBV products can do the job for you, our ventilation engineers are available to offer you advice. But you should expect us to ask you questions not only about the air volume and your heating/cooling requirements, but also about the end user's expectations and needs. We see it as a process of providing reliable advice based on dialogue.

KE Fibertec has gone against the tide by raising the technology level of the entire production process in Denmark by introducing new standards for the use of laser technology. All laser parameters aregenerated in our dimensioning programme WinVent 3D and are electronically submitted to our laser cutters. Not only did that increase productivity and product finish but it was also an incentive for us tointroduce a brand new product group, the so-called hybrid products.

The hybrid products combine the best properties from our passive low impulse systems and our high impulse systems.

A good co-operation is based on trust and for your next ventilation job we hope to get the opportunity to prove that this is not just empty words.
