  • Flexibility and tailored fabric ducting solutions

    Flexibility and tailored designs characterize KE Fibertec's fabric ducting 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, colors, materials, and whether the fabric ducting system must be passive, hybrid, or active.

  • Unique fabric ducting materials and colors

    We are the only manufacturer in the world to offer customized woven textiles from our own weaving mill. Our fabric ducting materials are designed for air distribution - not for tents or patio blinds - no shrinkage after washing, color-fastness, and not least, the best possible Dust Holding Capacity. We offer a wide range of standard colors, and our textiles may be dyed in any desired color according to a standard color system (request a custom color quote today!).

  • Efficient air distribution and perfect indoor climate

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

  • Fire approved fabric ducting materials

    Naturally, all KE Fibertec fabric ducting materials have been fire-tested and approved according to international fire standards and UL listed according to NFPA 90A. Furthermore, the products are classified as air distribution devices in accordance with ICC Evaluation Service AC167 and UL 2518.

  • Hygienic and easy to maintain

    All fabric ducting systems are easily removed 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 fabric ducting 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 antimicrobial effect is non-existing at rates below 85% RF.

  • Excellent acoustic properties in fabric ducting

    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 fabrics act as sound baffles below the ceiling, where they absorb and break down part of the noise reflected.

  • No condensation problems with fabric ducting

    All our low impulse and hybrid ducts 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 fabric ducting materials weigh 6.9 to 11.8oz per square yard, which is much lighter than spiral ducts. At the same time, fabric ducts are much easier to handle and to transport as they are folded and packed in cartons with a maximum weight of 55lbs. KE Fibertec's suspension rails are delivered in exact lengths rendering installation easier and quicker than similar systems.

  • Sustainable ventilation

    All KE Fibertec fabric ducting textiles are tested and approved according to the Oeko-Tex® Standard 100. Our production is certified according to the ISO 14001 standard (Environmental Management System). Transportation and disposal of fabric ducting systems produce less CO2 pollutants than conventional steel ducts. CradleVent is the world's first Cradle to Cradle ventilation duct for sustainable building.

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 centers, 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 fiber 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 UL 2518, 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

  • Nomex

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

    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 fabric materials are woven at KE Fibertec's own weaving 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-stabilized, 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 will lead to pulsations around the inlet because the material's weave has become too loose.

Colors

We offer a wide selection of standard colors, and with extra payment, we can supply you with fabric ducts in whatever color you need, e.g. according to the RAL color system.

A healthy indoor climate and energy savings with fabric ducting

Learn why fabric ducting is a good solution in the interview with National Sales Manager Ken Rummage

Why choose KE Fibertec as your ventilation partner?

Creating a perfect indoor climate involves more than just selling fabric ducting products. For KE Fibertec, it's all about dialogue, expertise, reliability, and logistics. We don't stock finished products or have standard components. All our fabric ducting 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 better the chance we have of achieving the desired results. Fabric Ducting can replace more conventional air distribution fittings in almost every situation, but only if the design is tailored to the particular task.

KE Fibertec has gone against the tide by raising the technology level of the entire production process by introducing new standards for the use of laser technology. All laser parameters are generated in our dimensioning program WinVent 3D and are electronically submitted to our laser cutters. 

A good working relationship is based on trust and for your next ventilation job we hope to get the opportunity to prove that these are not just empty words.
