low-e glass doors and windows with its excellent insulation and noise effects are gradually becoming the new home of the doors and windows of home decoration products. But as long as the building materials market stroll, people will find a wide range of hollow glass doors and windows, although the appearance is white plastic steel frame, decorated with glass, but the price is divided into three or nine, from 200 yuan / square Rice to 1000 yuan / square meters range, dazzling, consumers are also difficult to choose when buying, then, how should choose hollow glass? China curtain wall network editorial department, through the product library hundreds of glass brand and Thousands of glass products for sieving analysis, summed up the following three aspects, identify the true "false" insulating glass Cheats, and share the five kinds of express to distinguish the quality of insulating glass tips:
First, whether the glass is sealed. The true insulating glass is composed of two layers of glass, surrounded by high strength, high air tightness composite adhesive glass and seal, the glass bar is sealed and sealed, sealing performance is superior, many false glass doors and windows of the two glass Is a black PVC foam bar bonding, in fact, no sealing effect.
Second, the low-e glass of the middle of the two glass 6-9mm air layer, the bottom of the aluminum barrier, aluminum partition has a lot of ventilation holes in the air layer filled with dry gas, the border filled with desiccant for absorption Gas in the water to prevent the glass doors and windows after the heat "foggy" condensation phenomenon to ensure that the glass between the air dryness, and poor quality of the false "hollow" glass is no such equipment, and in half a year or Longer hours after the internal fog and can not wash the situation.
Finally, the field test the insulation effect of doors and windows. Because of its hollow glass leaving a certain cavity characteristics, and has a relatively good insulation effect, so in the northern city has been very widely used. In the sound insulation performance, the high-frequency noise in the insulating glass has a good sound insulation effect, but the effect of low-frequency noise (such as bus engine noise, train noise, aircraft noise, etc.) is not obvious, because the hollow glass air cavity at low frequency Area and the outside world of low-frequency noise resonance, low-frequency noise is relatively easy to pass through the glass into the room. Of course, false "hollow" doors and windows of the sound insulation effect is very general, and almost no insulation performance.
Industry insiders to distinguish the advantages and disadvantages of hollow glass doors and windows five tips:First, the quality of profiles identified
High-quality profiles, from the appearance of oxidation coloring film surface smooth and delicate, smooth and clean, pure color, no bleaching; no bubbles, linear smooth, broken section of silver, not black, with weight; corrosion resistance, Durable, then select the profile from the following aspects to be judged:
1. Look at whether the use of materials meet the standards: high-quality insulating glass doors and windows are used in high-quality profiles, such as the more well-known domestic Rimic profiles, Wei Chang profiles, aluminum profiles, luxury profiles, and low-quality hollow glass doors and windows are used low Profiles, such as "thin" products, the current market, the thinnest profile of only 0.6mm (according to national standards for aluminum wall thickness requirements, profile wall thickness of 1.2 ± 0.23mm, tensile strength should reach 157N per square millimeter , The yield strength should reach 108N per square millimeter, the oxide film thickness should reach 10μm, if not above the standard, as low-quality aluminum), and even moved the hands of the secondary recovery profiles (appearance affixed to the well-known profiles Of the film, shoddy).
2. Look at the appearance of fine degree: the surface protective film no obvious scratches, no aluminum scraps, burrs, oil spots or other dirt, adjacent components coloring no obvious color, assembly joints without spill adhesive, door window frame size error, There is no broken open welding phenomenon; hardness thickness enough, with a hammer hit the profile surface does not appear broken. Poor quality of the profile processing shoddy, cutting with sawing processing, cut the surface is extremely uneven, uneven color, bubble impurities, poor hardness, with a hammer percussion will be broken, or even hand pinch will be deformed.
3. To see whether the use of convenience, safety: high-quality aluminum installation stress, solid components, doors and windows open flexible, non-blocking or rebound phenomenon, doors and windows closed, the pressure tightly closed, between the frame and the connection was no obvious Gap; In addition, the hardware is also a direct impact on the performance of doors and windows.
4. To see whether the manufacturer is formal: the current market processing of aluminum factory large and small numerous, unknown small factory or workshop production of aluminum quality is certainly not guaranteed, the use of the process of frequent failure, Security risks huge. Therefore, the choice of regular manufacturers is the effective guarantee of quality, manufacturers have production licenses, the obvious parts of the product signs, such as factory name, trademark, product name, model, factory date and so on.
Second, the profile of the steel lining is also installed on the quality difference
To enhance the rigidity of the profile, more than a certain length of the cavity need to fill the steel lining lining (ribs), the state clearly stipulates the doors and windows to wear steel lining at least a minimum of 1.2 cm thick, good steel thickness of 1.2 mm or more , And poor quality profiles used steel lining is often not enough thickness, most of the market is 0.9 cm, and some even with the recovery of scrap metal, petrol bucket leather or wood stuffed. In this regard, some processing point responsible person vowed that the steel lining does not need 1.2cm, the quality is the same, this statement will mislead many consumers, after all, most consumers are not expert, often will doubt the consumption of doubt. But in fact, if the steel liner does not meet the standard, time for a long time, the profile will be deformed.
Third, there are multi-cavity profiles and single cavity of the points
Multi-cavity profiles from a main chamber (installation of steel) and a number of small cavity composition, good insulation and drainage performance, and single-cavity Fourth, the glass quality identification qualified products
