Three major techniques for door and window purchase: one look at two touch three switches

As the saying goes: The insiders look at the doorway, and the layman looks at the excitement. For friends who don’t know about doors and windows, buying doors and windows is really a headache. There is no standard in my heart, and there is no positioning. As a result, many people are dissatisfied and uncomfortable after purchasing.
Also, the current door and window industry is rich in categories, the categories are dazzling, the quality is also uneven, coupled with the shopping guide "small and sloppy", strolling around in the store, it is impossible to start, there is no way to judge. Xiao Bian has years of experience in the industry, summed up the seven-character slogan: one look, two models, three switches. Can be collected for emergency needs.

The so-called "early listening to all directions, eyes on the six roads", so "seeing" is very important for those who buy doors and windows.

Second touch
"Touch and touch, more than three hundred", don't be afraid, go to the store to buy windows and doors to touch does not cost money. I can only feel the good or bad of it if I touch it myself. Especially for doors and windows, touch is an indispensable step, of course, touch and knock can be matched.
Touch the surface: with or without particles, scratches and undulations;
Two touch corners: whether there are burrs or gaps;
Three-touch strip: whether there is looseness;
Four knocking surface: there is no abnormal sound, the quality of the product is generally good

Three switches
Switching doors and windows is also an important step to judge the quality of doors and windows.
Sliding door sliding and sliding sound is small and has a bearing weight as a good product. If the push and pull is very laborious, and the noise is like a running train, it means that there is a problem with the product design or production adjustment. If the push and pull is too light, the material is insufficient.

Open the window inside and outside the open experience, if the light and no noise is better.
Whether the switch handle rotation is flexible.
If the internal and external switches are jingle and squeaky, it means that the work adjustment is not in place or the hardware accessories are not up to standard. Another reason is that the open position of the design is too large and the load is too heavy. These are unreasonable.
