Lead: The front small series (Shanghai Qinguan soundproof window) introduced the soundproof window brand soundproof window. The last article forgot to say what was said this time, but it doesn't matter if it is too late. Xiao Bian This explains to everyone how to buy soundproof windows. I believe everyone knows that too many manufacturers of soundproof windows often confuse regular manufacturers and ordinary manufacturers and do not know how to choose. Don't worry, let's talk about the secrets of soundproof windows for everyone.
Sound insulation profiles?
The sound-insulating window profile has the characteristics of high strength, strong corrosion resistance and low deformation. Why do some soundproof windows have disappeared after one year of use? After analysis, under normal use, the soundproof windows are deformed, probably because the thickness of the soundproof window profiles used is too thin. It is understood that the sound insulation window currently available for consumers in the building materials market has various thicknesses such as 0.8 mm, 1.0 mm and 1.2 mm. The sound-insulating window with a thickness of 1.0 mm or more is better, and it will not be deformed for 5 to 8 years under the premise of normal use. However, some small manufacturers cut corners in order to reduce production costs, even using sound-proof window profiles with a thickness of only 0.6 mm. Such soundproof windows are prone to deformation due to insufficient thickness of the material.
Xiao Bian reminds: the thickness of the profile directly determines the pros and cons of the soundproof window door. When consumers buy soundproof windows, don't try to use cheaper soundproof windows. For the cheap soundproof windows, black heart manufacturers may give you cheap profiles.
Welding process?
"The production process of soundproof windows is relatively simple, many small manufacturers can produce, but the quality is mainly in the production process is fine." The soundproof window experts introduced that the level of welding technology reflects the quality of the soundproof window door. High-quality soundproof window doors, fine processing, and exquisite welding, especially the stitching parts are very flat. Inferior sound-insulating windows and doors, blindly use aluminum profiles and specifications, processing rough and shoddy, door frame corners and other positions can not be flattened, and sometimes even larger gaps. When purchasing, consumers should pay special attention to check for welding defects, such as open welding and leakage welding. Also check whether the door and the door frame are closed, whether the gap is uniform, and whether the opening is flexible.
Xiao Bian reminds: After checking the welding process of the soundproof window door, consumers should carefully check whether the paint surface of the product is bright and the texture is clear. Note that the paint surface cannot have obvious scratches, bubbles and other defects.
What is the recommendation?
How to choose a soundproof window:
1, first understand the sound insulation window on the market and its sound insulation performance 2, ask the business about the soundproof window knowledge, sound insulation window can achieve a effect, price, ask for its after-sales service, etc. 3, look at the quality management certification certificate to the business 4 When signing the contract, the sound insulation of the soundproof window and after-sales maintenance service are agreed. And ask for the effect of the contractual requirements of both parties after installation, and then pay the amount, so as not to be deceived.
5. Check the window material after installation. For example, check the protective film on the profile. The protective film has a digital code for identifying the true and false profiles, and input it to the specified channel control. All profiles have an identified identification code. Authentic can be found. Prepare the game for the civet cat to change the prince.
