Thermal insulation energy-saving aluminum alloy doors and windows making three elements

[China Aluminum Network] The doors and windows of buildings are part of the external structure of buildings, and are the most sensitive parts of building heat exchange. The energy consumption per unit area is 5-6 times that of walls, and the heat loss of doors and windows accounts for the entire building. More than 40% of the material. There are three ways for the heat loss of doors and windows outside the building: heat conduction loss through the aluminum alloy profile at the front; second, radiation heat loss through the glass; and third, air convection heat loss through the door and window gap. Therefore, the production of insulation and energy-saving aluminum alloy doors and windows must also be considered from these three aspects.

1. Aluminum alloy material Aluminum alloy material is a good conductor of heat, and the thermal conductivity is mostly high. To make heat-insulating glass, it is necessary to select the section that has the heat-insulating bridge treatment, that is, to cut off the heat conduction path of the section to achieve the purpose of heat insulation.

2. Insulating glass is required for glass thermal insulation doors and windows because the hollow space between the hollow glass is filled with dry, static air, which greatly reduces the thermal conductivity. Therefore, the insulating glass has excellent thermal insulation, sound insulation, and frost-resistance. , Condensation performance, commonly used glass hollow glass thickness 5 ~ 6mm, common cavity thickness 9mm, 12mm.

3, Sealing material Thermal insulation doors and windows with the sealant should use weatherproof adhesive, sealant should choose anti-ozone corrosion resistance and anti-ultraviolet aging performance of fine neoprene products, door and window fan to open the coincidence part to set more than three sealants Article.

Natural Ledgestone panels are made from hand selected pieces of natural stone that fit together for easy installation. The range of color in each panel is exquisite. Each are composed of thin rectangular and square pieces of stone. These thin, lightweight stone panels are a perfect alternative to larger natural stone pieces and create a seamless, modern finish.

These items are a perfect complement for inside and outside wall,bathrooms,backsplashes,flooring,and fireplaces.The combination of designs that can be created from these products are endless.
