[China Aluminum Network] heat insulation bridge doors and windows sealing effect is good, sound insulation effect of heat insulation, good wind pressure resistance, rain water penetration is good, is the grade of durable type. Frameless balconies have a variety of properties, but they have good daylighting, good ventilation, and nice appearance. The structure of the thermal break bridge profiles is different from the aluminum alloy and the plastic mold, the middle of the profile is broken, the heat conduction channel is blocked, the sound insulation effect is better than the aluminum alloy and the plastic just. This is also a more important design. It is a major advancement in the form of exterior windows. Ensuring energy conservation in buildings is a major measure for the country's energy efficiency in residential buildings. Disadvantages: There is basically no disadvantage, and sometimes there is less water seepage. The price is centered and is [popular] type. The aluminum-wood composite window is a frame formed by compounding an aluminum alloy aluminum alloy section and solid wood with a thermal insulation bridge. Has a good anti-deformation and anti-aging ability, natural harmony, full of nature charm. Compared with the thermal insulation, the noise and heat insulation effect of the broken profile doors and windows are better. Because the interior is the effect of solid wood, it is better than the aluminum alloy and plastic steel grades, and the indoor high-end home improvement.
