Large pieces of glass in bedrooms of high-rise residential buildings need to be replaced. Trouble? What should I pay attention to when I find someone to replace the property? How can we see the quality of glass? Thank you. More troublesome.

It needs professional replacement, but finding someone to replace the property will save a lot of trouble. As a non-professional, the quality of glass is mainly concerned about whether the color is uniform and whether there are defects such as stones and bubbles, which are not the best. Ask the construction personnel whether they need to prepare in advance. Before replacement, you need to go to the site to do some measurement and other related work.

See if the glass can be taken out of the house. Now many glasses are installed outdoors. It has little impact, and it will inevitably bring some cleaning problems when workers enter the house, which is not easy. The most important thing is to ask the property company to prove whether the glass belongs to safety glass, which is stipulated in our country's norms. Safety glass (tempered glass, insulating glass, etc. ) You must use 1.5 square meters.

Extended data:

1. Spread the newspaper on the floor inside and outside the window to catch the glass fragments. Then stick some cover tapes on the window glass. The adhesive tape must pass through the glass surface and stick to the window frame to reduce the flying of glass fragments.

2. Wear leather gloves, goggles and thick leather shoes, and beat the window glass from top to bottom with a hammer. The bigger the cup, the better.

3. Use an old chisel to chisel away the glass fragments and putty fragments left on the window frame. Old glass inlay nails can be pulled out with pliers and replaced with new flat-headed nails.

4. Remove all dust from the window frame and apply primer on the notch until it is dry. If you want to let the window sit overnight before glazing, you can cover the window with plywood.

5. Put putty in your hand to make it soft and plastic. If putty sticks to your hands, you can wet your hands or roll putty on the newspaper to let the newspaper absorb some oil.

6. Take a piece of putty in your hand, squeeze it out with your thumb and forefinger and embed it in the notch of the window frame. The thickness of putty is about three centimeters.

7. Carefully embed the glass into the putty, and gently press around the glass, instead of pressing only one of them hard, so as not to break the glass and cause injury.

8. After installing the glass, knock in a flat nail every 250 cm. You can knock the nail with the side of the chisel, and the nail head should protrude five centimeters from the groove.
