1. Thermal insulation
Why aluminum-clad wood doors and windows can reach level 8 because the wood of aluminum-clad wood doors and windows is A-grade material and has a low thermal conductivity k value. Mercedes-Benz automotive-grade float glass, equipped with LOW-E film, reduces infrared heat radiation by more than 90%. Realize the thermal insulation and heat insulation functions of windows. It will make the indoor temperature 5 degrees cooler in summer and keep the indoor temperature 5 degrees warmer in winter. So what does the k value mean? K value is the conductivity coefficient, which refers to the heat transferred through an area of 1 square meter in 1 hour under certain conditions when the temperature difference on both sides of the window is 1 degree (K, ℃). The unit is Watt/square meter·degree (W/㎡ •K), the lower the k value, the better the thermal insulation of the window.
2. Wind pressure resistance
Wind pressure resistance refers to the ability of a closed window to avoid damage and dysfunction under wind pressure. The wind pressure resistance of windows is the basic physical property of doors and windows. The wind pressure resistance design of doors and windows shall be implemented by the relevant requirements of GB 50009 "Load Code for Building Structures". Aluminum-clad wood doors and windows are designed in advance, and the whole window is installed and shipped from the factory to avoid problems such as unstable installation. The hardware accessories used are imported from Germany, which have strong load-bearing capacity and are sturdy and durable. Therefore, even if there is a typhoon blowing outside, the aluminum-clad wood doors and windows can withstand the test.
3. Water tightness
Watertight performance refers to the ability of a closed exterior window to prevent rainwater from leaking under the simultaneous action of wind and rain. The outer aluminum of Tianrun aluminum-clad wood windows adopts seamless full welding technology, labyrinth cavity design, hidden drainage technology, and internationally advanced pressure strip inner sealing technology to effectively prevent rainwater from entering the room. Equipped with an equal pressure drainage cavity to ensure that seepage water is discharged. Water tightness 500pa can withstand heavy rain attacks.
4. Airtightness
Air tightness refers to the ability of a window to prevent air penetration when it is closed. Tianrun's aluminum-clad wood windows adopt Germany's advanced 9-step sealing technology and are equipped with German sealing strips, EPDM strips, etc. as standard. They are checked at all levels to completely isolate the internal and external environments. Block dust, block haze, block wind, and block water. Even if the room is empty for several months, there is no dust and the room is clean and pollution-free.
5. Sound insulation
The sound insulation performance of windows refers to the ability of doors and windows to reduce the transmission of sound from the sound source to the listener. Tianrun aluminum-clad wood windows adopt aviation-grade silent technology. The glass is made of three glass and two cavities filled with inert gas, which effectively reduces sound wave conduction. The frame is made of ultra-thick solid wood to naturally shield sound transmission, achieving a silent and noise reduction of more than 42 decibels.
Aluminum-clad wood doors and windows are made of a solid wood main frame covered with a layer of thermally insulated broken bridge aluminum alloy. Polymer nylon parts are used between the two, and they are mechanically connected, fully taking into account the different shrinkage coefficients of wood and metal. This kind of window adopts a double-layer sealing structure and uses Low-E glass to ensure sealing and protect against infrared rays, making it more suitable for the needs of a healthy home.
