Due to the influence of COVID-19, the amount of take-out orders has increased further, and when many people order in and out of the store, the inside of the store is complicated and inconvenient to customers. To mitigate this, a window-type folding door has been installed so that customers can purchase it from outside without having to enter the old store, so that it is not complicated indoors and can be delivered quickly to visitors.

Opening the door when the weather is good gives you a cool sense of openness and expansion, and in summer, it blocks hot heat from the outside with insulation effect to maintain indoor cooling temperature, and in winter, you can feel insulation and soundproof effect.

Balanced fixing and construction are the most important points and techniques for long-term use of folding doors with smooth driving without any minor failures. Our Polzen Korea has installed a perfect and strong folding door with many construction know-how for many years.
