Like doors, windows are one of the passages connecting indoors and outdoors, but the difference is that windows are set up so that there can be more circulating air and sufficient light indoors. In leisure time, looking at the scenery outside through the window can make people feel cheerful. But did you know? There are many types of windows, such as fireproof windows, anti-theft windows, soundproof windows, escape windows, thermal insulation windows, etc. Different floors, rooms and requirements require different types of windows. So what are the functions of windows? What is the role of windows? What kind of window fits your room?
Fire window
The role of fire windows
Fireproof windows are mainly composed of steel window frames, steel sashes, and fireproof glass; they can protect people’s lives and reduce financial losses.
Advantages and disadvantages of fire windows
Steel fire window
Advantages: excellent fire resistance and heat insulation; economical and practical, low cost; equipped with fireproof hardware and temperature control devices.
Disadvantages: The aesthetics is worse than aluminum fireproof windows.
Plastic steel fire window
Advantages: economical, energy-saving and environmentally friendly; meet individual needs; good airtightness, heat insulation, no deformation on the whole, and no aging of the surface.
Disadvantages: poor high temperature resistance, easy to soften under high temperature roasting.
Key points for purchasing fire windows
Check the certificate: Generally, fireproof windows will be tested before they are sold, so at this time you have to see whether the specifications, dimensions and materials of the tested samples are the same as the ones you actually purchased. When you buy, you must ask the manufacturer for a type inspection report.
Workmanship quality: Good fireproof windows are generally made with better craftsmanship, and the appearance should be complete, free of damage, and no burrs on the surface.
Logarithmic value: See whether the description of the sample tested is consistent with the specifications you choose, and the thickness of the fireproof glass should be consistent with the described thickness.
Look at the seal: Qualified steel and wooden fire doors should be equipped with a fire seal, which should be straight, without arches, and have a qualified inspection report issued by a national-level inspection agency.
Anti-theft screens
Principle function of anti-theft screens
The anti-theft net screen refers to the integrated anti-theft net and screen window, which can effectively prevent all kinds of mosquitoes, mice, snakes, etc., and also effectively prevent explosions, burglaries, etc.
Advantages and disadvantages of anti-theft screens
Combination anti-theft screens
Advantages: It can be disassembled; windproof and mosquito-proof, 100% sealed; screen windows can be removed and washed at will; easy to use, rigorous structure.
Disadvantages: It can be disassembled and washed at will, the stability is not high, and it is easy to be worn and damaged.
Diamond net anti-theft screens
Advantages: high anti-theft strength; prevention of falling objects from high altitude; invisible and transparent, no sense of barrier; easy to open, easy to escape.
Disadvantages: high price, incomplete cleaning, high space occupancy rate, and inability to engage in outdoor activities.
Key points for purchasing anti-theft screens
Gauze: It is best to choose stainless steel wire sprayed or higher grade alloy metal gauze, and the diameter of the metal wire is above 0.8mm.
Frame: A thick and stable frame can play the role of fixing the gauze. It is recommended to use aluminum alloy profiles with a thickness of at least 1.4~2.0mm.
Hardware: The anti-theft screen door and window accessories are an important part of the anti-theft. The multi-point fixed key design of the multi-point lock can strengthen the anti-theft function.
Sound insulation window
Principle function of sound insulation window
The sound insulation window uses a specially processed sound insulation layer, and the sound insulation layer uses a sound insulation glass composed of sound insulation damping glue (film) firmly bonded by high temperature and high pressure. The traffic noise dropped to an extremely quiet level below 45 decibels.
Advantages and disadvantages of sound insulation windows
Advantages: high sound insulation; good quality without deformation, durable; strong wind pressure resistance, good airtightness; rainwater leakage, dust and sandstorms; flexible opening, safe and reliable; beautiful appearance and novel structure; large lighting surface, scrubbing convenient.
Disadvantages: high cost and more expensive.
Points for purchasing sound insulation windows
Sound insulation: The higher the sound insulation, the higher the price of the sound insulation window, but it is recommended that the sound insulation should not be less than 30dB.
Window type: fixed windows have the best sound insulation effect, followed by casement windows, and the worst is sliding windows.
Glass material: Vacuum glass has the best sound insulation effect. Insulating glass can only isolate high-frequency or low-energy noise. The sound insulation effect of multi-layer insulating glass is average.
Sealing strips: The sealing strips should be made of soft, elastic and anti-aging materials. The sealing strips should be closed and there should be no gaps in the four corners.
Insulation window
Insulation window principle function
Insulation windows generally refer to the transparent outer protective structure of a building with a certain heat resistance capacity. The main thermal parameter is the heat transfer coefficient K value (in W/(m2·K)). The smaller the K value, the better the heat resistance, that is, the better the heat preservation effect, but it may affect air tightness and cause indoors The number of air changes decreases, which affects indoor air quality.
Key points of thermal insulation window design
Improve the thermal resistance of doors and windows to reduce the amount of air infiltration.
