Therefore, consumers should pay attention to the quality of their glass when they purchase. Generally speaking, the quality of the glass is definitely better than that of ordinary glass. When purchasing, you should gently tap the glass door and listen to the sound of the glass. The tempered glass is crisp and the ordinary glass is boring and low.

When choosing upvc/Aluminum glazed door, we still have to look at its pulley. Generally high quality upvc/Aluminum glazed door, its pulleys are more durable. Therefore, when consumers purchase, they can press the pulley by hand or push it to judge its quality and flexibility.

4.Look at the thermal performance of the upvc/Aluminum
The winter is relatively cold, the indoor heat is easily radiated to the outside through the doors and windows, and the outdoor cold air is also easy to invade, so the warmth of the upvc/Aluminum is also one of the problems to be considered when purchasing. If the household chooses double-layer insulating glass during the decoration, the heat preservation effect will be significantly improved compared with ordinary glass. Double glazing prevents heat transfer, which protects against the cold and heat of the house and prevents the loss of energy inside the house. At present, the ideal energy-saving glass has a double-insulation hollow coating glass, in which the empty layer has a thickness of 12 mm, and the glass can maintain a good indoor temperature.
In addition, in the winter and summer, due to the large indoor and outdoor temperature difference, the room with double glazing is more comfortable than the room with single glazing. Assume that the outdoor temperature is -10 ° C, the indoor temperature is 20 ° C, and when the surface temperature is increased to 10 ° C, when the single-layer glass window is used, the glass surface temperature is 1 ° C, because the window temperature and the human body temperature are far apart, when the human body is close to the window It will absorb a lot of radiant heat from the human body, which will naturally produce an uncomfortable feeling.
When double-glazed glass is used, the temperature difference between the window and the human body is greatly reduced. In addition, because two layers of insulating glass are installed, the combination of the outer wall and the door and window will be more strict, and the outdoor noise and dust can be blocked outdoors, the noise is reduced, the environment is green, and the health of the occupants is also beneficial. Consumers should also be reminded that if you buy a thick curtain of cloth as a decoration for the house, the insulation effect will be better.

When buying upvc/Aluminum, we have to look at its price. Generally high quality upvc/Aluminums, its price is relatively expensive. Therefore, when consumers are shopping, they must not choose cheap products for the sake of small profits.
