Therefore, today Xiaobian will share the self-test method of door and window tightness, which can help our owners to check more carefully in the acceptance of doors and Windows, I hope to help you!

A4 paper self-test method

If the decoration is selected to open the window, in fact, we just need to prepare a piece of A4 paper to plug into the window and the frame. Then the door and window lock pull the paper, if the paper does not fall off that the sealing effect is in place, on the contrary, the sealing is not qualified products.

Pressing method

If the window in the home is an external window, we can lock the window first, and then push the window around the corners. If the four corners are found to shake obviously, the sealing effect of the door and window is certainly not good, and the sealing effect is not good directly affects the quality of life.

Incense verification method

There is also a simpler method, which is suitable for pushing and pulling Windows, outside Windows, and inside Windows. We just need to light a incense, and then placed in the joint of easy air leakage, if the smoke is only slowly upward, it shows that the tightness is good, and if the cigarette appears slowly offset then it shows that there is air leakage, so we can use the above method to judge whether the door and window sealing is not qualified and other problems, if found should be immediately feedback.
