What types of doors and windows are there?

Although the main intelligence is ventilation and lighting, the performance and quality are constantly improving. Let our life have more choices and more convenience. So, how many kinds of windows are there now? Have you ever heard of them?

The windows are divided into the following 11 types according to the opening method.

01.fixed window

Fixed windows cannot be opened, generally without sashes, only the glass can be embedded in the window frame. Sometimes sashes are also provided to produce the same façade effect as other windows, but the sashes are fixed to the sash. Fixed windows are only used for lighting and viewing, and are usually used in occasions where only lighting is considered and ventilation is not considered. Due to the fixed sash, the glass area can be slightly larger.

02.sliding window

Sliding windows have the advantage of not occupying indoor space, and large pieces of glass can increase indoor lighting. But the ventilation area is smaller (only half of the open window). At present, aluminum alloy sliding windows and plastic sliding windows are widely used.

Casement window is a traditional window type with the widest range of applications, divided into two types: inward opening and outward opening. It is easy to clean the window when it is opened inside, but it occupies indoor space when it is opened. The window sash that opens outward has good waterproof performance, and does not occupy indoor space when opened, but it is easily damaged in strong wind and rain, and requires higher strength of hardware. The biggest feature of the casement window is that the sealing performance is good, the sash can be fully opened, which is convenient for ventilation and has a simple structure.


Shooting windows are equivalent to down-hung windows, which are more suitable for small windows such as kitchens and bathrooms, or hotels and office buildings with central air conditioning. Sometimes they are used in conjunction with casement windows and sliding windows.
