Doors and windows are divided into enclosure members or partition members according to their locations. Different design requirements have functions such as insulation, heat insulation, sound insulation, waterproof, fire prevention, etc. Now let's see how to buy screens. Look at the gauze. The quality of screens is, first and foremost, gauze. Yarn has domestic and imported points. Most of the imported fiber material; domestic glass fiber, there are some plastic material. Imported high-quality fiber screens can be tens of thousands of push-pull friction without distortion; domestic glass fiber generally only withstand a few thousand times; and plastic screens because of the material relationship, easy thermal expansion and contraction, the possibility of deformation. When purchasing gauze, pay attention to two points: First, look at the net hole is uniform, the thickness of the yarn is uniform; second is to touch, good quality gauze feel quite scraping, like iron burned in general, generally The fiberglass screens are soft. Second see the border material. High-quality screen frame more choice of spray or electrophoresis of aluminum alloy profiles, a variety of colors. The border is good or bad, is to see its thickness, high-quality thickness of the border profile should be more than 1 mm, thickness less than 1 mm, after using five or six months is easy to deform, affect the normal open. Three to see accessories. Accessories that directly affect the use of screens and doors include bearings and springs. At present, the low-priced screen doors and windows on the market are all made in China. Most domestically-made bearings are open-type. Once they enter the dust, the operation will be unsmooth. After an ordinary spring is used for a period of time, the elastic force of the spring will decrease, and the gauze will not rewind into the yarn box. It is recommended to purchase a fully enclosed silent bearing and special spring. Nowadays we all know that environmental protection is not a simple slogan but a major event that is closely related to everyone’s life. The quality of screens depends on two aspects. One is the environmental protection of materials and the other is the environmental protection of design. Doors Doors and Windows Villa Design Window Glass Aluminum Alloy Glass Door
