In order to improve the safety of living rooms, nowadays, more and more materials and categories of doors and windows, such as plastic materials, have been praised by many consumers, it can not only effectively improve the safety of personal property inside the home, but also Helps to prevent theft, mainly using stainless steel metal materials, through the steel structure of the firm, so as to form a solid and strong steel doors and windows, will not allow outsiders to easily enter your home, then the plastic doors and windows is good or not? The following along with Xiaobian Let's go and see.
Plastic doors and windows are not good
First, the advantages of plastic doors and windows
1, energy saving
Compared with other materials, these products are more energy-efficient, can effectively improve the indoor temperature environment, with relevant data show that a single glass steel aluminum window heat transfer coefficient is about 64W/M2K, single glass steel window heat transfer coefficient is Around 47W/M2K, the heat transfer coefficient of ordinary double-glazed steel-aluminum windows is about 7W/M2K, and the coefficient of heat transfer of double-glass plastic steel windows is about 5W/M2K. Therefore, plastic steel doors and windows have good Energy-saving features.
2, good sound insulation
For households living in urban areas, the increasingly noisy environment seriously interferes with daily life. Therefore, in the selection of door and window materials, sound insulation products are more preferable, in which the acoustic performance of steel-aluminum doors and windows is about 19 decibels, and steel-plastic doors and windows are The soundproofing performance is more than 30 decibels, so plastic doors and windows can improve people's living environment quality, and also have good corrosion resistance, and are suitable for use in corrosive environments such as coastal and chemical plants.
Second, the disadvantages of plastic doors and windows
Due to the brittleness of these materials, they are heavier than aluminum alloys, and they emit toxic emissions when burned. At the same time, they have poor steel properties. They must be internally attached with steel bars to increase the hardness. In addition, the fire performance is also improved. Slightly worse, if the fire protection requirements are relatively high, aluminum alloy material is recommended.
Plastic steel doors and windows are expensive
1, the price of such products vary according to different sizes, generally speaking, the price from 500 to 1,500 yuan a flat have, the specific price also need to be determined according to different circumstances, of course, the price of different profiles will be different Normally, the price of ordinary flat open plastic steel windows is generally around 600-700 yuan, and the price of flat-open doors is generally around 500-600 yuan. Push-pull type is relatively cheap.
2. The price level of different cities is also one of the factors that affect the price level. Of course, the quality is not the same. The price is also different. The general quality is only 180~220 yuan per square. If it is a good quality brand manufacturer, it must be 250. ~ 350 yuan per level, the current top ten brands of plastic windows conch, Shide, LG Haojiaxi, Beixin, Kemei orders, Vicat, Baoshuo profiles, South Plastic Steel, etc. are all very good brands, price is very high.
Summary: Well, the above is about the quality of steel doors and windows introduced, I hope to provide you with some help, I believe that in the future of plastic doors and windows purchase process, friends will be more handy, buy their own products.
