Why can’t kindergartens use glass doors?

Security issues.

Children in kindergartens are young and have a wide range of activities, so they are prone to accidental collisions. If a glass door is used, once a collision occurs, the glass may break and cause injury.

Kindergartens generally use wooden doors or plastic doors. This is because these two door materials are relatively safe, highly durable, easy to clean, and suitable for the use needs of kindergartens as a special place. The specific choice of door depends on the actual situation of the kindergarten.
