When you choose doors and windows, do you ask you when you enter the store to sell it, do you want the 70 series, 75 series, or 80 series? As the owner, are you confused?
Hello everyone, in fact, these commonly heard numbers represent the size of the window frame occupying the wall, that is, the specifications of the window frame. It is not that the larger the number, the better the insulation effect. It only means that the larger the profile, the more materials used, and thus the more expensive it is.
In fact, if you want a good insulation effect, you still need to look at the cavity structure and glass configuration of the window. If the configuration is the same, the insulation effect is no different.
Of course, each manufacturer has different positioning of product specifications. Different specifications and configurations can be selected for different customer usage scenarios and needs. Doors and windows are large-scale customized products. Don’t blindly follow the trend and see what others buy and what you buy. After all, the location and environment of each community are different, and the demand points are different. The best one is suitable for you.
