Now the Internet era is updated quickly, and the home aluminum alloy doors and windows are also being updated. Engaged in selling doors and windows every day, I am learning how to choose Windows with good performance with users. Our users also search for high quality doors and windows on the Internet, or consult in the doors and windows physical stores in the old building materials market nearby. By the way, take photos and upload them to the internet. Compare them with those on the internet to see the performance and low price. Now, the owners who know how to customize the doors and windows of good brands to share the doors and windows that need to be decorated:
look at the origin of Brand Aluminum
when you customize the material of any type of doors and windows, plastic steel doors and windows, aluminum alloy doors and windows, broken bridge aluminum doors and windows, aluminum-wood doors and windows and so on, more progress to view the doors and windows belonging to that type of brand. Brand doors and windows are divided into, one is the enterprise specializing in the production of building aluminum profiles, and now it also produces brand doors and windows of so-and-so aluminum, such as Phoenix aluminum, Jianmei aluminum, Weiye aluminum, etc. The second category is to register a brand of system doors and windows. His focus is to improve the performance of the door and window system. For example, the doors and windows of the German technology system under the brand xxx.
Second, look at the wall thickness of aluminum profile materials.
The national standard stipulates that the thickness of door & window profile should be greater than or equal to 1.4mm. Most door and window factories choose products with high output rate, that is, products with relatively thin wall thickness to reduce the cost. However, the insulation strip of bridge-cutoff aluminum alloy doors and windows is nylon and has certain requirements for the wall thickness of aluminum materials for doors and windows. Therefore, the wall thickness determines the ability and firmness of wind pressure resistance.
Three look broken bridge aluminum doors and windows heat insulation strip
the insulation strips of broken bridge aluminum series doors and windows are made of PA66 imported nylon materials, which are made according to the National door and window standards. However, many door and window manufacturers in the market occupy the point that consumers do not understand the materials. They steal beams and change columns, and use PVC plastic insulation strips that are common in the market and have low prices instead of imported nylon materials, in this way, the use of low-cost materials will reduce the use safety, service life and use Effect of doors and windows to some extent.
Four look custom doors and windows standard glass
standard glass accounts for the largest proportion of doors and windows. There are many kinds of glass, bridge-cutoff aluminum alloy doors and windows of which are made of high-quality hollow glass. The standard thickness of regular hollow glass is 5mm. Between the two pieces of glass will join aluminum and strip, so the thickness of the whole glass is between 12mm and 15mm. This is based on the door & window profile specification. In order to ensure the safety of doors and windows, the area of bridge-cutoff aluminum alloy doors and windows hollow glass larger than 1.5 square meters needs to be tempered.
Five look at the number of doors and windows opened by Casement
the opening of Casement is calculated based on the number of square meters of the housing price, because it involves lighting, thermal insulation, ventilation, etc.
Six look at the sealant strip of door and window accessories
one look, two smells, three stretches, this is the simplest and roughest way to judge whether sticky strip is true or false. The color of the adhesive strip with favorable quality will be pure black, even if you look closely at its surface, there will be no bump. The sticky strip with excellent quality smells rubber and does not have strong pungent phenomenon. Finally, you need to pull sticky strip by hand, which is flexible and not easy to fold. Then it is genuine goods rubber strip. Bridge-cutoff aluminum alloy door and window rubber strip imported EPDM products are selected, with a service life of 30 years.
