Best Quality Powder Coated Aluminum Profile for Window & Door

Aluminum aluminium Window Profile Aluminum aluminium Window system

WinGreen Window & Door System adopts a new profile called Polyurethane Aluminium which owns a number of invention patents and is the upgrade form of traditional broken bridge profile. But WinGreen directly fills foamed polyurethane with highly heat preservation and heat insulation performance into the gap between the Aluminium profiles to realize its solid heat insulation instead of the traditional nylon insertion methodology for broken bridge.(picture one)
Polyurethane Aluminium, whose components are Aluminium and Polyurethane, are divided into Aluminium outside profile, Aluminium inside profile and Polyurethane core from outside to inside.
 
Aluminium is widely used as the raw material for window and door profile, which not only has high strength and is easy to shape and maintain, but also has long quality guarantee period and can be recycled. In addition, a variety of surface treatment on it can be done to achieve diversified decorative results according to people's different preferences. The Aluminium outside profile of WinGreen meets all the advantages mentioned and especially can be customized from color to gloss to meet your needs. The Aluminium inside profile of WinGreen which has went through standard oxidation processing, directly combined with Polyurethane, can be stockpiled for a long time and can combine outer profile with different surface into a whole so as to meet the different requirements of various customers.
 

Polyurethane is a very common polymer industrial raw materials, which is flexible, durable and has been applied in different fields and thousands of products to replace materials like paint, cotton, rubber, metal and wood. It can be hard as glass fiber, soft as foam, elastic as rubber, and adhesive as glue. Polyurethane used by WinGreen belongs to the rigid polyurethane which is mainly applied in the construction industry. However, application of Polyurethane is not mature in this field and it mainly applies heat preservation function in refrigerators, freezer in China. In addition to the series of products with different density and hardness, it can also be further processed and be added functions like sound-absorbing performance, flame retardant, antistatic property, radiation protection, etc. Polyurethane is widely used in various products from children's toys to aircraft wings, and has been improved continually to adapt to the modern technology since it was invented in 1940. WinGreen adopts water base foaming technology and adds flame retardant to strengthen fireproof performance of the system. The U valueof Polyurethane core of WinGreen profiles is 0.062W/(m2.k).
 
Now WinGreen owns series of profiles, separately named WG75 and WG85, which has the same structure but different heat insulation performances. The U value of WG75 is 0.96 W/(m2.k) while the U valueof WG85 is 0.75 W/(m2.k).
