What kind of pvc sliding window is good? How to judge the pros and cons of pvc windows? We should start from the following aspects to judge the pros and cons of pvc windows.To judge the pros and cons of pvc windows.
- Sound resistance performance.
Sound resistance performance is an important factors to identify the quality of pvc windows. When observing and purchasing doors and windows, you should repeatedly sliding, open and close several times, and pay attention to whether there are abnormal noises that shouldn’t be heard. A good pvc window will have no other sound except the normal sliding rail sound.
- Look at the appearance.
The appearance of high-quality pvc windows should be smooth and tidy, and there should be no cracks, un-welded, crimped edges, and grooving. In addition, it is required that there is no gap between the window sash and the window frame when the window is closed, the sealing strip is flat and intact, and the rubber strip must not smell.
- The four doors and windows should be a whole without screws.
- Look at the hardware.
The hardware must be made of corrosion-resistant and rust-proof materials, and must be installed firmly and in the correct position, and no noise can be emitted during use.
- Look at the glass.
It is best to use insulating glass as a supporting use for pvc windows. In addition to good sound insulation, insulating glass is far stronger in sealing and heat preservation than insulating glass, but it should be noted that there should be no moisture and dust in the inter-layer. The glass should be flat and free of water marks. Glass and plastic profiles should not be in contact, there should be a sealing bead close to the gap, and glass glue should not be used. If it is double glass, there must be no dust and moisture in the inter-layer.
- Select the profile.
First of all, we must understand the PVC profiles selected for pvc windows. PVC profiles are a decisive factor affecting the quality and grade of pvc windows. Good PVC profiles contain anti-aging and anti-ultraviolet additives in their formula, with smooth surface and blue-white color. The color of middle and low-grade profiles is white and yellowish. This color has low sun protection ability. After a few years of use, it will become more and more yellow, until it is aging, deformed, and brittle. Considering that the windows of most houses are relatively large and there are many high-rise buildings, so you should choose a profile with a wall thickness greater than 2.0 mm and a three-chamber structure. In this way, it can be guaranteed that the windows will not be deformed after decades of use. In addition, this profile is not easy to change color and age.
