Areas of application and differentiation from other technical brushes
In contrast to other technical brushes, brush seals have a flexible brush base. A large number of fine brush hairs are woven into the brush base or, in the case of an extruded base, welded in. The filling is usually made of polypropylene. Brush seals are often also referred to as sealing brushes or sealing brushes. They are usually supplied rolled up on a spool so that the seals can be further processed. Brush seals are used in the furniture industry, in roller shutter construction, in insect screens and in the automotive and caravan industry.
They are not suitable for sealing doors or gates (as door bottom seals). Depending on the application, either door seals, door brushes or a stainless steel wire brush should be used. The latter serves to protect against mice and other rodents.
Possible uses and application examples
Brushes are versatile. Brush seals are used in the building trade as well as in industry. Brush seals are used to seal and insulate doors, gates, windows and roller shutters. Among other things, they can be used for thermal insulation and to prevent dust, draughts, odors and noise. In industry, they are used as technical brushes. They are used to seal machines and systems, to clean machines and to gently guide and carry goods and transportation systems.
Brush seals for roller blinds and roller shutters
Brush seals play an important role in roller shutter construction when it comes to preventing rattling and running noises. Brushes are used here at various points to guide the slats of the roller shutters gently and silently.
Brush seals in guide rails (roller shutters/blinds)
Roller shutters and roller blinds protected by brush seals run through the guide rails without annoying rattling. Brushes are inserted into the grooves in the guide rails. The slats of the roller shutters only come into contact with the brushes, not with the guide rail itself. This protects the roller shutters or roller blinds and also means that no noise is generated. A brush seal can also be inserted into the end rod at the bottom of the roller blind. This protects the material when it comes into contact with the floor or window sill and prevents rattling when the roller blind is put up.
Brushes in roller shutter boxes
Brush seals are also used in roller shutter boxes to minimize the running noise of the roller shutters. A look inside a roller shutter box shows where the brushes need to be fitted.
Where the roller shutter leaves the box, two brushes guide the slats gently and silently through the opening. In our application example, a strip brush in H-profile and a brush in F-profile have been fitted.
Brush seals in window construction
Brush seals are used in window construction primarily because of their heat-insulating properties. A positive side effect is the noise-insulating property of the brushes.
Brush seal in the cladding of the window frame
In this application example, a brush seal is glued into the cladding of a window frame. The moving elements of the window for opening and closing are not affected by the brush. The brush therefore helps with thermal insulation.
Brush seal for attaching insect screens
When installing insect screens, brushes are used to securely seal small gaps. The brush helps to prevent insects from entering and the screen does not rest directly on the surface (window sill or floor). The surfaces are thus protected from scratches even if they are opened and closed several times.
Brush seals in furniture construction
In the furniture industry, brush seals are mainly used to protect moving elements and prevent dust.
Prevention of damage and dust
If large surfaces run past each other, there is a risk of damage on contact, e.g. scratches. Brush seals ensure that the cabinet elements do not touch each other.
The application example clearly shows that the brush gently guides the sliding door without the risk of damage. Another positive side effect is that the cabinet door runs smoothly in the track and does not rattle.
Brush seals can also be attached to the bottom of cabinet doors to protect against dust, damage and noise.
Brush seal – flexible in use
Brush seals are flexible. Thanks to a large number of fine brush hairs that are woven into the brush base or, in the case of extruded brush bases, welded into it, the brush seal remains flexible and can adapt perfectly to any substrate and surface.
Thanks to their properties, the seals also adhere excellently to curves and edges. They provide a permanent and reliable seal even in difficult areas, and self-adhesive brush seals with self-adhesive 3M tape are particularly popular. Alternatively, we also offer the brushes with less expensive hot-melt adhesive.

Silent Fin *NEW*
Low-noise brush seal
The newly developed “Silent Fin” brush seal ensures a particularly high level of comfort thanks to its quiet operation
With conventional brush seals with center foils, running noises are perceptible during operation; center foils cause running noises on windows and doors, for example. With the Silent Fin “CFS”, two soft, textile-coated center slats replace the film. This special structure results in absolutely quiet operation.
Silent Fin: When the slats are unfolded, the special structure of the middle slats becomes visible. The soft slats run smoothly over each other.
The Silent Fin brush seal is not only characterized by its noise reduction. It also meets the other quality requirements that we have for all our brush seals. The silent Silen Fin brush seal therefore also provides reliable protection against draughts or smoke and is, of course, opaque and dust-tight.
