Aluminum windows and doors belong to building profiles, usually with 6063 brands do. Demanding surface (surface to oxidation treatment), other physical properties also have certain requirements. Domestic market to do this a lot, especially in the Yangtze River Delta area. Good windows and doors on the market, depending on the brand, quality is different, not the same price. As phoenix aluminum, it is relatively good, the price will more expensive than ordinary. Cheap, not a small plant, that is, its product is defective. Buy when the attention of the Austrian! What hardness is not enough, ah, surface blistering, ah, ah wrong size, and so on. Aluminum doors and windows have beautiful, pest moth, easy to clean and so on. The disadvantage is that sealing is not good (water, sound), you need to pad strip, easy to wear for a long time; you can not bump, affecting the appearance and so on. Of course, there are many types of aluminum windows and doors on the market, the advantages and disadvantages are not the same.
Broken Bridge aluminum-plastic composite window style advantage?
Bridge-type aluminum-plastic composite window principle is the use of plastic profiles (insulation 1250 times higher than aluminum) will be separated from both inside and outside layers of aluminum alloy and tightly connected as a whole, constitute a new type of insulation aluminum, doors made with this profile, their insulation and plastic (steel) window in the same class - GB level, solve the aluminum heat conduction fast, does not meet the energy requirements of a fatal problem, while taking some of the new The structure of the complex form, completely solve the "aluminum sliding sash Mifengbuyan" chronic problem. The products on both sides of aluminum, plastic profiles intermediate cavity do adiabatic material.
Performance and advantages: 1. good insulation: plastic composite profiles of plastic low thermal conductivity, excellent heat 1250 times better than aluminum, 2 sound good: its structure was designed seams tight, test results, noise 30 db, in line with the relevant 3. Impact: Because the outer surface of plastic composite profiles of aluminum alloy, so it than the PVC window profiles impact 4. tightness good: aluminum composite windows are installed at the aperture multi-channel seal tops or plastic strips, air tightness is level 5. Watertight good: water proof windows and doors designed structure, completely cut off in the outdoor rain, 6. Fire is good: Aluminum is a metal material, not burn. 7. The security is good: aluminum composite windows, hardware accessories and advanced configuration excellent decorative locks so that thieves do nothing 8. Maintenance-free: plastic composite profiles are less vulnerable to acid erosion, will not turn yellow fade, almost no maintenance. Aluminum doors and windows broken insulation with good thermal insulation properties, the "Three North" New Construction (northeast, northwest and north) and other winter cold areas to be widely used in the country. In 2000, Beijing in a number of construction projects begin to install and use insulated aluminum windows and doors, as "built outside Ha!", "Sunshine 100" and other projects, the past two years, Beijing insulated aluminum windows and doors market share year by year.
