BEIJING Jia Yu old brand. It has been listed in 2010, and now it mainly develops door and window products, photovoltaic products, etc. The doors and windows of this brand are not a big brand, but the quality is relatively good. I am recommend jiashi doors and windows! My home is also newly decorated. At first, I wanted to continue to use the traditional tempered glass windows. But the seal is not very good, it is easy to water in rainy days, so I changed it jiashi doors and windows, I didn't expect it to be really good. Rain can't come in on rainy days. The sealing is very good, the sound insulation is also very good, and it can also resist wind pressure.
Jiashi doors and windows S series products have good appearance and texture. It has a light luxury and high-grade sense with our decoration style, and this window is designed with narrow frame, after I changed it, I could obviously feel that the transmittance of the whole room had doubled. The most important thing is that the waterproof performance is really very good. In rainy days, the window slot does not have the phenomenon of water seepage, and there is no need to worry about the problem of water seepage damaging the wall. Moreover, after several months of sun and rain, according to my observation, there was no fading of window frames and no color difference between doors and windows.
