The folding slide and turn windows can classfy two aspects:

 1. Single window

Principle: A glass piece of glass is pushed to one side of the balcony and turned on. Advantages: Full open, 100% release of balcony space; standing on the inside can easily clean the sides of the glass; single glass can be turned 90 degrees.

Disadvantages: Each piece of glass needs to pass through a designated craft mouth to open; and before opening the middle sash, it must open its front piece.

Process: Non-linear installation is more expensive and costly.

Applicable balcony: "one" shape, "L" type, circular arc, shaped, full coverage of all shapes.

  2. Double linkage window

Principle: Every two pieces of glass are connected with a hinge, two pieces move together to the sides of the balcony, and rotate to open. Advantages: Full open, 100% release of balcony space; two pieces of glass can be independently opened at any position; connecting two pieces of glass can be turned 90 degrees.

Disadvantages: Outdoor glass is inconvenient to clean.

Process: simpler installation and lower cost.
