Which province has the most high-end door and window factories?

There are many high-end door and window factories in Guangdong, many of which are located in Foshan, Guangdong, such as Aowei, Fu Xuan, Anger, Beauty Choice, Red Oak, Schneider, Oupai and so on.

Distinguish between high-end door and window profiles and low-end door and window profiles;

The quality of broken aluminum doors and windows can be distinguished mainly from the following aspects: cavity design, whether the window sash is glued, and whether the joints with glass and insulating glass are sealed:

1. Cavity design: high-precision nylon heat insulation strip, which is in contact with rubber strip to ensure the overall strength and accuracy of doors and windows. When the temperature changes, rubber strip will not be deformed, which will increase the waterproof and dustproof effect;

2. Whether the frame fan is glued or not: there is a sealing rubber strip outside the fan, and the corner of the frame fan is assembled by German two-component glue, which ensures that it is more flexible to open, will not bump, will not fall off the corner after long-term use, and will ensure the service life;

3. Insulating glass: use sealing strips instead of sealant on both sides of the glass to ensure that the glass does not directly contact the profile.

The stress is more uniform, and the glass will not burst due to the change of climate and wind pressure. The most important thing is that the contact between glass and profile is closer and the waterproof effect is better.

4. Insulated glass: the thickness is more than 5MM, the glass hollow layer is not less than 12MM, and the glass surface is free of water ripples and green, which is safer and protects the family; Sound insulation, heat preservation effect is better, more transparent, better lighting.
