Doors and windows market products are mixed, there are many poor quality products, consumers need to pay attention to screening. What should consumers pay attention to when they buy? It's an expert who introduced some of the problems that might exist in some products in the market and how to identify them.
Jiangke Doors and Windows
Profiles: mainly see the flexibility
In the material of the profile, calcium carbonate is relatively cheap, and some small manufacturers will use calcium carbonate in large quantities, resulting in the profile being brittle, cold and easy to crack, and even tearable. Some profiles are small and thin, which can also lead to reduced stiffness and affect wind pressure resistance and Other properties. At the time of selection, consumers can take a sip and see how flexible it is.
Accessories: thickness not less than 1.5mm
Using inferior hardware may result in poor switching within one year. The spread of sealant strips can reach more than 10,000 yuan per ton. The use of quality products will cause shrinkage, hardening and cracking of the strips within one year. Some manufacturers do not even add reinforced steel bars in the profiles, or the thickness of the steel bars may lead to a significant reduction in the life of the profiles. Reinforced steel is used to improve the wind resistance performance of the window. The thickness should not be less than 1.5mm. After adding steel, the plastic window has a certain weight, and consumers can use this as a criterion.
Glass: Two layers of glue required
In general, glass requires two layers of glue: one for bonding glass and a frame, and the other for sealing between glass and insulating water vapor and air. However, some manufacturers only made a layer of seals, which caused the windows to leak soon after use, and the insulation effect was greatly reduced. This link requires the manufacturer of the window to have the appropriate machinery and equipment. When selecting the window manufacturer, consumers can ask the manufacturer whether the glass is customized by a professional manufacturer or produced by oneself. If it is produced by oneself, it needs to have an insulating glass production line and a machine wiper. And so on, as far as possible do not choose artificial wipe, through these issues to determine whether the manufacturers have the appropriate production capacity.
