The brush seal is made from polypropylene with 3M adhesive. The adhesive is very strong, making it easy to attach the seal. We apply the seal to a clean and dry surface. This ensures that the connection between the seal and the surface is durable, allowing the brush seal to be used for a long time. The brush acts as a barrier against dust and dirt, dampens noise, and prevents insects from entering. The seal reduces noise from sliding doors on furniture and windows, and it also prevents sliding doors from slamming.
