Manufacturer’s product description
The STEIGNER brand brush seal is a self-adhesive seal for doors and windows. With its extra-strong adhesive surface, the STEIGNER self-adhesive brush seal ensures quick, easy installation and a secure hold – without any drilling or screws. The flexible brush, with a base width of approximately 6.9 millimeters and a brush height of 12 millimeters, is ideal for sealing cabinets, drawers, windows, and garage doors. Thanks to its fine polypropylene bristles, the sealing brush effectively protects against dust, drafts, and noise. It prevents the penetration of cold, heat, moisture, dust, and insects and contributes to thermal insulation – ideal for saving energy and reducing heating costs. It also provides reliable service in furniture construction, for example to reduce noise from roller shutters or cabinet doors. The door brush adapts flexibly to any surface and impresses with its resistance and durability – suitable for indoor and outdoor use. Installation is quick and easy: simply cut to the desired length, remove the adhesive backing, and stick it on.
The product is available in five colors (white, beige, brown, gray, and black) and in various heights and lengths – for tailor-made solutions and quantities to suit your needs. Manufactured in the EU.

When you pick up the product for the first time, you immediately notice the even bristles.
The bristles feel pleasant and very dense.
An initial examination of the adhesive surface revealed that the adhesive strength on the back of the bristles is very strong. It can therefore be assumed that the product can be attached and adhered well.
It can also be assumed that the product can be shortened as needed by simply cutting it to size with scissors.
Overall, this product makes a positive first impression.

This brush seal was subjected to a thorough practical test.
In terms of fit, it can be said that the seal is ideal for doors, windows, and even drawers.
When testing the adhesive strength, it was noticeable that the product adheres very strongly to surfaces such as wood or plastic. Very good, even adhesive strength was observed over the entire length of the product.
After closing the window, it was found that the draft at the bottom of the window decreased significantly after installing the brush seal, ensuring that it was airtight.
Repeated opening and closing of the windows and doors did not affect the product in any way.
If the product needs to be removed from a specific location, it can be removed without leaving any adhesive residue, and it is no longer apparent that a brush seal was attached.
In practical tests , this product proved impressive thanks to its easy installation and effectiveness.
