We divided the folding doors into 2 places so that we can enter the book cafe right after being outdoors in the book cafe located on the first floor and constructed 10 folding doors, 5 pieces each.​
The color was constructed in chocolate color, and we chose a soft chocolate color that would be more suitable for book cafes than a modern and stylish black color.
Many adults visit the education center, but many young children, elementary, middle, and high school students visit there, so it can be more friendly with a softer chocolate color.

The installation of insulation folding doors prevents outside temperatures from entering the room during the hot summer months and the cold winter months.​

If the folding door is closed with a rubber gasket between the doors, the sealing force is increased, preventing the inflow of outside temperature.
Also, the lower rail is equipped with a mohair and bracket to prevent external temperatures from entering even a small gap.​

As a result, the room temperature can be maintained regardless of the season, along with saving on air conditioning and heating costs.
