What Factors Does The Insulation Performance Of Doors And Windows Depend On?

As the "article" connecting indoors and outdoors, doors and windows play the main functions of lighting, ventilation, receiving sunlight, and providing people with a view. With the development of science and technology and the continuous improvement of people's living standards, the thermal insulation performance that affects the comfort of home has become an important function of doors and windows.

For novices in decoration, choosing doors and windows for home decoration is a very troublesome problem. They have to face many problems such as how to distinguish whether a product is of good quality, whether the heat insulation is not good enough, and so on. When you go to a store to buy doors and windows, the shopping guide will tell you which door and window has good quality and good heat insulation performance, and recommends you to buy it. If you know how to distinguish between good and bad products, it will be difficult to buy door and window products that really meet your wishes, and you may even be cheated.

In general, to judge whether the thermal insulation performance of a door and window is good enough, you can directly look at the K value of the door and window (the thermal insulation coefficient of the door and window). The lower the value of K value, the stronger the thermal insulation ability of doors and windows, and the better the thermal insulation performance of doors and windows. The thermal insulation performance of a door and window is mainly determined by the following factors.

①Sealing strip

The thermal insulation performance of doors and windows is closely related to the overall sealing performance of doors and windows, and the sealing performance of doors and windows is determined by the quality of the rubber strip and the number of sealing channels (usually the thermal insulation effect of three seals is better than that of two seals), and Whether there are isotherms on the same straight line or plane inside the profile. Because, when the hot and cold air is exchanged inside and outside the doors and windows, the two broken bridges are in the same straight line or plane, which is more conducive to forming an effective cold-thermal bridge barrier, reducing the conduction of cold and heat in the air, and reducing unnecessary heat loss.

②Insulation strip

Although the area of the insulation strips of doors and windows is not large, it is an important part of the insulation of doors and windows, which determines the insulation effect of doors and windows and also determines the experience of using doors and windows. The thermal insulation quality of many broken bridge aluminum doors and windows on the market is determined by the heat insulation strips, so when purchasing doors and windows, you must pay attention to the quality of the heat insulation strips. The better the heat insulation strips, the less heat transfer between indoors and outdoors. The better the insulation.

③Hardware accessories

Hardware accessories are also divided into good and bad, the better the quality, the better the heat preservation. Hardware accessories determine the opening and closing of doors and windows, the smoother the opening and closing, the better the sealing. When purchasing doors and windows, be sure to check whether the hardware accessories are of high quality.

④ Door and window glass

The area of door and window glass generally accounts for 70% to 80% of the area of doors and windows, or a larger proportion. Because of this, the thermal insulation performance of glass has a great influence on the thermal insulation performance of the whole window.

In terms of thermal insulation performance, good hardware accessories and sealing strips are the key to doors and windows.
