Honeycomb or honeycomb net is made of thin layers of paper or cardboard that are connected in parallel and at equal distances. Honeycomb finds a honeycomb-like structure with small hexagonal houses when used on both sides.
The main application of honeycomb is in hollow (hollow) doors. Hollow doors (hollow core) consist of a wooden frame that forms the main skeleton of the door with covers on both sides.
The difference between hollow doors and solid doors is that instead of using solid and solid materials such as pieces of wood that were previously used in the construction of solid doors, hollow doors use honeycomb.
The use of honeycomb instead of rigid and solid materials has many advantages, including features such as: light weight and easy portability, less hinges when installing doors, flexibility in design and shape, the possibility of making panels And pointed thin and long doors, economically viable and environmentally friendly.
