The thermal insulation of aluminum-clad wooden doors and windows is mainly related to the structure of aluminum-clad wooden doors and windows. The interior surface of aluminum-clad wooden doors and windows is made of imported wood after deoiling and degreasing treatment, and then painted four times. The heat conductivity is better than that of metal. The difference is much worse. At the same time, the outside of the window is made of aluminum profile, and there is a thermal insulation module connection between the aluminum profile and the wood. In this way, the cold air in the room is not easy to pass out, and the hot air in the outdoor is not easy to enter the room, thus forming a better heat insulation. performance.
Aluminum-clad wooden doors and windows have strong heat insulation and sound insulation properties. In recent years, aluminum-clad wooden doors and windows have become the reason everyone likes because of their excellent functions, the warm feeling of wood and the superior durability. The characteristics and functions of wooden doors and windows, aluminum-clad wooden doors and windows not only have the beauty of superior wood appearance, but also the appearance of aluminum-clad wooden doors and windows. Aluminum-clad wooden doors and windows are now more and more popular by users of high-end villas and luxury houses.
Wood density of aluminum-clad wooden doors and windows
Wood density is an important indicator of wood properties, which has very important practical significance. According to the actual weight of wood, we can infer the technical properties of wood and the physical properties of wood such as shrinkage, expansion, hardness and strength of wood. The wood density is mainly based on the basic density and the air-dry density:
1. Basic density: Because the air-dried wood weight and raw wood volume are relatively stable and the measured results are accurate, it is suitable for comparison of wood properties. It is also practical in wood drying and antiseptic industries.
2. Dry density: It is the ratio of the weight of the air-dried wood to the volume of the air-dried wood. The wood density when the moisture content is between 8% and 20% is usually used as the air-dry density. The specified moisture content of 12% is the air-dry density of our country. The air-dry density of wood is the basic basis for comparison of wood properties and production and use in China.
