>>> Five strokes to let poison steel doors and windows
As soon as the rainy season arrives, the old windows and doors have inconvenience to many families because they do not have a drainage function. The new plastic steel window has staggered the design of the drainage groove and the air pressure balance hole to avoid the direct entry of cold wind and dust, and the drainage hole part is equipped with a closed cover to prevent rainwater from flowing into the room from the hole.
The window plays a key role in lighting, ventilation, and heat preservation, and its quality cannot be ignored. At present, there are three types of plastic window windows on the market: flat open, top suspension, and push-pull. In terms of price, the price of sliding windows with screens is relatively low, at a minimum of 300 yuan per square meter; and due to the complexity of accessories and installations, the top-hanging windows are the most expensive, and the imported brands are around 1,000 yuan. In color, in addition to ordinary white and brown, colored windows are not uncommon in the market. Some of the texture windows give buyers even more personal space.
In addition, high-quality plastic steel doors and windows use excellent flame-retardant materials, do not help combustion, once the fire can self-extinguish; in addition, its internal is a closed multi-cavity hollow structure, can reduce noise about 30 decibels; doors and windows have soft cracks Quality PVC seal, when closed, it is airtight and airproof. It is understood that good plastic doors and windows can reach 30 years of service life.
Buying instructions: subtle differences between the advantages and disadvantages
Must go to the formal building materials market to buy plastic windows. The price of plastic windows sold on the market today is very different. The double-glazed steel windows produced by small processing plants sell for more than 200 yuan. They can also be measured on the above doors and installed free of charge. In the formal market, the general double-glazed casement windows cost about 400 yuan per square meter, and some open windows for insulating glass, plus screens and other expenses, cost more than 1,000 yuan per square meter. The technical content varies greatly among them. The roadside stalls have poor processing equipment, and the precision and strength of the doors and windows cannot be guaranteed at all. Moreover, the quality of the inner lining steel of the profiles is poor, there is no lining steel, and other accessories are also poor. The formal brand steel window in the regular building materials market is more secure in the quality of the profiles.
As the plastic windows on the market are mostly assembly windows, the quality of doors and windows needs to be distinguished from the fine details when purchasing. The appearance color of plastic steel doors and windows should be blue and white, and the color is too white or gray, which means that the stable ingredients in the material are not enough. It is easy to age and turn yellow. It is necessary to check whether the hardware is flexible and smooth; the auxiliary materials such as beading and sealing of steel doors and windows. Should be matched with the main profile; the cavity structure of the plastic window determines its heat insulation and sound insulation effects; the drainage grooves and air pressure balance holes are processed in a staggered position to avoid the direct entry of cold wind and dust, and the assembly of relatively strict plastic steel window drainage holes Some parts are equipped with a closed lid to prevent rain from flowing into the room from the hole; the sliding window window frame should have aluminum slides in the lower part to facilitate its replacement. In general, the double pulley is better than the single pulley. Because the lifespan of the sealing strip is shorter than that of the window; the middle of the sealing strip of the sliding window sash should have a fixing piece, which is the key to the sealing performance of the sliding window.
During the renovation, since the window removal process will destroy the internal and external walls, it is better to replace the doors and windows before proceeding with the next step.
Before installing the plastic window, it is necessary to determine whether the window is open inwards or outwards. Since the plastic window needs to be fixed by punching, it cannot be reinstalled once the installation is completed. Therefore, you must carefully consider before installing. During the installation process, the horizontal and vertical alignment of doors and windows should be supervised. The styrofoam is used for filling between the window frame and the wall, and the inside and the outside of the window frame must be sealed with silicon copper glue to prevent water seepage. After installation, the protective film must be removed, otherwise it will reduce the service life of doors and windows.
