The Fiberbinder Method

Fiberbinder is a new Danish-developed product that binds loose fibers from e.g. asbestos and mineral wool and thereby makes it safer to move and work in areas that have been remediated and cleaned.

Fiberbinder is the first of its kind on the market and therefore we have applied for an international patent for the product.

Fiberbinder ApS works for improving the working environment in connection with e.g. roof renovations, and The Fiberbinder Method also minimizes the risk of spreading asbestos fibers when roof sheets are dismantled.

The Fiberbinder Method can be used in the following areas:

Attic spaces

Attic spaces where it is not possible to remove all asbestos fibers or mineral wool fibers using vacuuming.

Roof tiles

Asbestos-containing corrugated eternite sheets and slate eternite before they are installed.

Mineral wool

Mineral wool bats before they are removed

Other objects

Other asbestos-containing objects before they are dismantled, e.g. boilers, pipe bends etc.

Other Historical dust

Historical dust and in areas where you would like to minimize the nuisance from dust in general while work is being done on the area.​​


Recommended retail price: DKK 20 – 25 per m2.

Range: Approx. 10 m2 per liters after mixing.

Battery-powered backpack sprayer: DKK 1,350 excl. VAT

A sticky liquid

Fiberbinder is a slightly sticky liquid that has been developed to fix the asbestos fibers that are present on surfaces, in cracks and crevices and in other inaccessible places where normal cleaning cannot reach.

The Fiberbinder Method is used on attic areas that have been thoroughly asbestos-sanitized and cleaned, and the method is also used directly on asbestos-containing roof tiles before they are dismantled, and on mineral wool batts before they are folded up and packed in bags. Fiberbinder is also used on other asbestos-containing items that must be removed and disposed of. Fiberbinder generally minimizes the risk of spreading fibers.

The use directly on asbestos-containing roof tiles before they are dismantled can help to limit the spread of asbestos fibers into the surroundings, and The Fiberbinder Method is therefore often used in connection with asbestos remediation of kindergartens, daycare centers, schools, high schools, etc.

The Fiberbinder Method in brief

Watch the film below:

The background

The background for the development of The Fiberbinder Method is that it often is impossible to remove all asbestos fibers by normal cleaning and extraction, even if this work is carried out very thoroughly. This presents the challenge that you sometimes end up cleaning many times, but that asbestos fibers continue to hide in rafter joints, cracks, crevices and other inaccessible places. This has the consequence that subsequent craftsmen such as carpenters, electricians and plumbers risk swirling up the remaining asbestos fibers and then risk inhaling the fibers with the great health risk this entails.

Easy to apply

Fiberbinder is applied easily and simply with a battery-powered backpack sprayer, and when the product lands on the surface and runs into cracks and crevices, it fixes the remaining asbestos fibers, thereby reducing the number of fibers that can be swirled into the air.

“It is a big challenge that it often isn’t possible to vacuum all asbestos fibers out of cracks and crevices. The demolition workers wear protective equipment for asbestos work when they carry out their work, but the following craftsmen and consultants do not wear the same protective equipment, and a solution is needed that can create better working conditions for the craftsmen and consultants who must subsequently carry out their work in areas that have been remedied for asbestos. We simply owe them that as a society”, says Morten Einshøj, co-owner of Fiberbinder ApS.

Thoroughly tested

Fiberbinder has been thoroughly tested in laboratory tests by Dansk MiljøAnalyse, and it can be  documented that you can achieve up to a 97% reduction in the number of asbestos fibers in the air with The Fiberbinder Method.

The main advantages of Fiberbinder are:

No shortcut

The Fiberbinder Method is a newly developed method that came on the market in 2021. As mentioned above, the actual application of Fiberbinder is simple and quick with an electrically powered backpack sprayer. Fiberbinder has both a pigment and a fluorescent tracer added, so that you can easily document the use in your QA material. The product contains no labeling obligation, health-damaging or environmentally problematic substances, and the product is easily degradable.

Fiberbinder ApS finds it important to emphasize that The Fiberbinder Method isn’t a substitute for the usual thorough cleaning and extraction. It’s a new tool in asbestos remediation which can help solve some significant problems.

It is important that The Fiberbinder Method is only used when the advisor on the case has cleared the area for fiber binding!

“Our product is not a shortcut. It does not replace thorough cleaning and extraction in accordance with current regulations and guidelines, and therefore it is also important that the use of The Fiberbinder Method only takes place in close cooperation between the demolition worker and the consultant”, Morten Einshøj points out!

Digital solution

In addition to the physical product that forms the basis of The Fiberbinder Method, Fiberbinder ApS has also developed a digital solution in collaboration with Molio, the Construction Knowledge Center.

The digital solution consists of an app, which has so far been prepared in Danish, English, German and Polish.

The app facilitates the process when preparing QA material, and it is intuitive and easy to use.

In the app, a combined pdf document is generated, which gathers all factual information about the case together with photo documentation of the work carried out.

In addition, the app contains clear introductions in the form of both text and videos for how The Fiberbinder Method should be carried out and how the image documentation should be made.

Behind the company

Behind the company you find two entrepreneurs.

Morten Einshøj, lawyer and former partner in a law firm, and Jesper Haunstoft, who as a master painter experienced a need to make workplaces safer in connection with asbestos renovation and therefore got the idea for the slightly sticky product, which has been developed with several partners.

Fiberbinder ApS works hard to make The Fiberbinder Method known and widespread. The preliminary feedback from, among others, municipalities, non-profit housing associations, demolishers, contractors and advisers has been positive, and we are now working towards The Fiberbinder Method being prescribed as standard at the end of asbestos renovation, not only in Denmark, but also in the rest of Europe and in USA.

Why is asbestos dangerous?

When working with asbestos and asbestos-containing material, dust can arise. The dust contains fibers in the form of very thin needles which can penetrate right into the tiniest branches in the lungs.

Inhalation of asbestos fibers can cause lung cancer, asbestosis and other chronic respiratory diseases, and it only takes a few fibers before it is harmful to your health.

Asbestos cannot burn and can withstand temperatures up to 900 °C, which is why it has been used for reinforcement, insulation and fire protection, just as it has been used in a wide range of building materials up to the mid-1980s. Asbestos can be found in cladding panels for walls, ceilings and roofs, in floor coverings and in special products such as asbestos-containing ventilation ducts, asbestos-cement pipes for water supply, sealants and plastering materials.

Although it is now prohibited to manufacture, import and use asbestos or asbestos-containing materials in construction, it still occurs in several older buildings, often in the insulation of pipes, containers, boilers, ventilation ducts, etc. The insulation is often made with diatomite mixed with asbestos, but insulation with almost pure asbestos can also occur.

During demolition work and repair of asbestos-containing materials, dust harmful to your health can easily arise.

Mineral wool is also harmful to your health

Mineral wool is a common term for insulating materials of either stone wool or glass wool.

Mineral wool is produced by melting stones and glass, respectively, at very high temperatures (approx. 1400 ° C). and can therefore withstand extreme temperatures during normal use and is therefore classified as fire retardant.

Mineral wool produced before 1997 is classified as a carcinogen in category 2 (carc. 2). At the same time, direct work with synthetic mineral wool products, e.g. insulation batts often causes irritation to your skin. The small fibers from mineral wool can also be very annoying – for a long time after the impact.

Therefore, it is an advantage to treat mineral wool with Fiberbinder during dismantling tasks, to avoid the forming of dangerous dust.

All work with asbestos and mineral wool must be done in accordance with the asbestos executive order and the mineral wool executive order, respectively.


More and more people realizes the benefits of using Fiberbinder as a supplement to the cleaning and extraction process in connection with remediation work with asbestos and mineral wool.
