It is also door that swings open on being pushed or pulled from either side and then swings closed by itself.

Other than swinging glass door, we recommended folding glass door to be used on the side entrance of Paradigm Mall.

The reason why we recommended folding glass door is because its designs and appearance look beautiful than a swinging door. It also have the almost same function as the swinging door although it may expensive and hard to install if compare to a swinging door.

2. Flush Door

Location: Service room of Paradigm Mall

Flush door have simple and flat surface on both sides. This type of door is more closely associated with function rather than style. Door of this type may have a solid or hollow core.

Two type of flush door:

(i) Solid-core door

(ii) Hollow-core door

(i) Solid-core door

This type of door have a solid particle board or woodblock core which is covered with layers of veneer. These doors are much heavier than a hollow-core door. Solid-core door provide better sound insulation and have less tendency to warp.

This door have a lightweight core made of various materials that are covered with layers of veneer too. This type of door is significantly less expensive than solid-core doors. It is usually used as an interior doors.

Suitability

Other than flush door we recommended to use panel door.

The reason why we recommended panel door is because it have better appearance and design than a flush door. Panel door also have the almost same function with the flush door. By the way, we still think that the flush door is more suitable for the door of service room because flush door have better resistance to scratches and crash.
