Brush seals 

You want to increase energy efficiency, reduce noise levels, keep dust out or prevent unpleasant draughts? Then you've come to the right place! In this article, you'll learn everything about brush seals - from their impressive functionality to their many uses and the differences in materials, colours and lengths. Discover how this kind of door seal can make your home more comfortable.

What are the benefits of brush seals?

Brush seals are versatile and effective solutions to perform different functions and solve different problems:

• Heat insulation: Brush seals are ideal for reducing heat loss, improving energy efficiency and supporting your measures towards greater sustainability. They are placed along doors, windows and other openings to prevent draughts and cold bridges.
• Noise protection: Due to their dense structure, brush seals provide effective protection against noise. They can be used in rooms with high noise pollution such as offices, workshops or music studios to reduce the sound level and create a more pleasant environment.
• Dust protection: Brush seals are also excellent for keeping dust and dirt out. For example, they are fitted to cabinet doors, sliding doors or roller shutter doors to minimise the ingress of dust particles and thus ensure a clean environment.
• Draft stoppers: Brush seals are perfect draught stoppers. They can be fitted to windows, doors or garage doors to reduce draughts and unpleasant draughts. This improves living comfort and reduces energy consumption.

Their effectiveness and ease of installation make them a practical solution for optimising indoor climate and energy efficiency.

Various applications: This is what the different types of brush seals can do

Brush seals are extremely versatile and can be used in various areas. Here you can find out how to use them effectively

In this post, we talk about three types of brush seals:

• Brush seals for the door bottom
• Brush seals which are mounted on the edges of doors and gates
• Dust protection profiles

Rollers and blinds - maybe new to you

Brush seals can be fitted along the guide rails of roller blinds and venetian blinds to create a better seal. This reduces the ingress of draughts, dust and noise. Self-adhesive dust protection profiles.

are used in this case.

Windows and doors - the classic area of application

Brush seals are an effective solution for sealing leaks on windows and doorsn. While dust protection profiles are used to seal the joints between the door frame and the door leaf, larger seals, which are screwed, glued or grouted to the bottom edge of the door, are usually used to seal the gap underneath the door.

Furniture and wardrobes - dust-free wardrobes at last

Brush seals are ideal for sealing drawers, cupboard doors and display cabinets. They prevent dust, insects and moisture from entering. They thus provide better protection and a longer shelf life for the furniture itself as well as the contents such as clothing etc. Here, too, self-adhesive dust protection profiles are predominantly used.

Garage doors - very practical especially in winter

Brush seals are also used for garage doors. They are mounted on the edges of the door to keep draughts, dust and dirt out. This is especially nice if you want to DIY in your garage in the winter without getting frostbite ;)

Sliding doors - very practical here too

Brush seals are also suitable for sliding doors and sliding glass doors. They are fitted along the rails or on the frame to create a better seal and reduce the entry of draughts, dust and noise here too.

This is how diverse brush seals are: Materials, colours and lengths at a glance

The choice of different materials, colours and lengths allows you to adapt brush seals to your individual requirements and ensure effective sealing in various areas.

This is how varied brush seals are: an overview of the materials, colours and lengths available

Seal brush materials

• PP (polypropylene): Robust and durable material with good resistance to moisture and chemicals.
• Ross hair: Natural material with soft texture that provides an effective seal while maintaining gentle contact.
• Polyamide:Very versatile material with high abrasion resistance and good resistance to oils, greases and chemicals.
• Artificial hair: Synthetic material characterised by flexibility, durability and good sealing properties.

Last materials

• Steel: Durable material for heavy duty and stability.
• Aluminium: Lightweight and corrosion-resistant material, ideal for use in humid environments.
• Plastic: Very versatile material, especially used for dust protection profiles.

Colours

• Stainless steel/grey: A classic, high-quality look for modern ambiences.
• White: A bright and clean colour. White brush seals are particularly popular in living areas.

Lengths

The lengths of brush seals vary depending on the area of application and individual requirements. Depending on requirements, brush seals are available in various lengths between 700 mm and 2500 mm.

Many models can be individually shortened, so you can cut them to the exact length you need using a hacksaw or angle grinder.

Fitting brush seals

Brush seals can generally be mounted in the following ways:

Adhesive: Because they are so easy to install, self-adhesive brush seals are becoming increasingly popular. All you have to do is peel off a protective film, press the seal firmly into place (it's worth cleaning it thoroughly beforehand) and the installation is done. Dust protection profiles also belong to the category of self-adhesive brush seals and are relatively easy to fit.

Screws: This variant is used for brush seals that are attached to doors and gates.

Welding: Some brush seals can be welded to the door leaf, for example. This type of mounting is mainly used in industrial applications.

Each door seal can be welded to the door leaf.

Slots: This variant is used, for example, for door bottom seals. First, a groove is milled into the door leaf, then the brush seal is inserted into this groove. This is an elegant solution because, depending on the position of the groove (on the side or on the lower edge of the door leaf), the seal is either much less noticeable or practically not noticeable at all.

Conclusion: Effective sealing for versatile applications

Brush seals offer a wide range of functions and applications. With materials such as polyamide and synthetic hair, as well as different colours and lengths, they allow you to tailor a seal for thermal insulation, noise protection, dust protection and draught exclusion. Use their versatility to improve comfort and efficiency in your home or workspace.
