The main materials for doors and windows generally include three aspects: aluminum profiles, glass, and hardware. The country has certain standards for the thickness, strength and oxide film of aluminum profiles used in aluminum alloy doors and windows.

-> The wall thickness of the aluminum profile of the aluminum alloy window should not be less than 1.2mm, and the thickness of the oxide film should reach 10 microns.

-> Considering the safety and durability of doors and windows, tempered glass is better than ordinary glass, and it is best to choose energy-saving glass.

->Stainless steel hardware accessories (such as screws, hinges, etc.) are better than aluminum accessories. Here are five common doors and windows

1. Casement Windows

The ventilation is good, so that the room can naturally circulate with the natural air, the indoor air is fresh, and the possibility of rainwater entering the room is eliminated. Clean air undoubtedly creates a comfortable living environment for people.

Safety refers to the various functions of the linkage hardware and handles arranged around the window sash indoors. When the window sash is closed, the four sides of the window sash are fixed on the window frame, so the safety and anti-theft performance is excellent.

Good sealing and heat preservation performance Through multi-point locking around the window sashes, the sealing and heat preservation effects of doors and windows are guaranteed.

The disadvantage is that the window width is small and the field of vision is not wide. The opening of outward opening windows takes up a space outside the wall, and it is easy to be damaged when the wind blows; while the inward opening windows takes up part of the indoor space, and it is inconvenient to use screen windows, and it is also inconvenient to use screen windows, curtains, etc. when opening windows .

2. Sliding Windows

Advantages of sliding windows: simple, beautiful, large window width, large glass blocks, wide field of view, high lighting rate, convenient glass cleaning, flexible use, safe and reliable, long service life, open in one plane, less space, and convenient installation of screen windows wait.

Disadvantages: The two windows cannot be opened at the same time, they can only be opened halfway at most, and the ventilation is relatively poor; sometimes the sealing is also slightly poor.

3. Awning Windows

Awning Windows This is a kind of aluminum alloy, plastic steel window that just appeared later. It is a new form developed on the basis of casement windows. It has two opening methods, which can be opened flat or pushed from the top. It can not only be ventilated, but also ensure safety. Because of the hinge, the window can only be opened by a gap of ten centimeters, and the hand cannot reach in from the outside. It is especially suitable for use when there is no one at home.

4. Outward-turning window (bottom-hung window)

That is, the bottom-hung window is a kind of aluminum alloy and plastic-steel window that appeared later. It can be pushed away from below. When casement window is closed, outwardly drawing the bottom of window, can open the gap of ten centimeters, say, that window can be opened from below a little, the part opened is downward suspension in the air, is connected with window frame by hinge etc. and fixes, Therefore, it is called the down-hung type.

5. European side window

European-style windows are decorated with European-style doors and windows. According to different regional cultures, they can be divided into Nordic, Simple European and traditional European. Among them, the pastoral style prevailed in Europe in the 17th century, emphasizing the change of linear flow and gorgeous colors. The other is the Rococo style, which loves to be decorated with light and slender curves. This needs to be matched with the overall style of the home.
