It happened that some time ago I installed sliding door of normal doors and windows. At present, I think the quality is good. I can introduce it to you. My sliding door is installed on the balcony, which is often exposed to the sun and rain, so I also want to buy a better quality and long service life. In addition, the normal doors and windows sliding door are quite stable when pushing and pulling, and will not easily hit the door frame, nor will there be too much resistance to push. At that time, I heard the introduction of the regular door and window shopping guide, sliding door has the heat insulation function. Recently, summer has arrived. It is very hot outside. The heat insulation function of sliding door is very useful.
