Reusable mechanical door frame fasteners without the use of building foam

Avoidance of pollutants and waste: two important factors for a circular economy

Several million frame fasteners are installed in doors every year in Germany alone. The Blue Angel for mechanical frame fasteners for room doors is awarded to products that are installed without the use of fitting foam and which can be easily removed and recycled separately when they are no longer required. This reduces any possible pollutant emissions e.g. from flame retardants in the fitting foam. The ability to remove and recycle the mechanical door frame fasteners at the end of their period of use also reduces waste. The environmental label thus promotes the concept of a circular economy.
