2026 Taiwan's Top 10 Airtight Window Recommendations: One Article Solves All Your Problems
How to choose an airtight window (soundproof window)?
However, with so many airtight window brands on the market, it's easy to get overwhelmed and wonder how to choose the right one. Don't worry, this article is your savior. We'll guide you through the entire process, covering key selection factors (airtightness, watertightness, wind resistance, sound insulation, glass, structure, energy efficiency, and construction methods), the top 10 airtight window brands recommended by netizens, and installation tips—all in one go! This will help you easily choose the right windows and create a quiet and comfortable dream home.
Don't be confused about airtight windows and soundproof windows anymore.
Many people's first hurdle before purchasing is: "What's the difference between airtight windows and soundproof windows?" Remember this simple concept: "A soundproof window is always an airtight window, but an airtight window doesn't necessarily have superior sound insulation."
- Airtight window: Its main function is to "seal" the windows, keeping out wind and rain. A qualified airtight window must meet the minimum requirements of national standards (CNS) in four aspects: airtightness, waterproofing, wind resistance, and sound insulation. Basically, it is an upgraded version of traditional aluminum windows.
- Soundproof window:
This is the "Pro Max" version of the airtight window. It puts a lot of effort into sound insulation, usually using thicker glass (such as laminated glass), stronger window frames, and adding several layers of airtight strips, with the goal of isolating noise to the extreme.
Should I choose an airtight window or a soundproof window?
Airtight windows: If you just want to keep out the wind and rain and improve your quality of life a little, choosing a good airtight window is enough.
Soundproof windows: But if your home is close to noise sources (like main roads, markets, or schools), then spending a little more on soundproof windows will definitely make you feel that the money is well spent.
Five key considerations for choosing airtight windows (soundproof windows)
Master these five key points, and you too can become a window selection expert, refusing to be ripped off and understanding the "health report" of your windows: National Standards (CNS). This is like a window's ID card, with four important numbers that directly tell you whether it performs well or not. When purchasing, feel free to ask the store to show you the "original manufacturer's test report," as the data on it is the most accurate.
airtightness
The airtightness rating indicates the amount of air leakage. The smaller the number, the less air leakage there is and the better the sound insulation . It is divided into four levels: 2, 8, 30, and 120. The smaller the number, the better, meaning that it is less likely to leak air. Generally, choosing a level of 8 or 2 is already a very good airtightness rating for a home.
- Low Standard/Ventilation Level: 120 Grade : This is the lowest standard for airtightness and the highest ventilation. Windows of this grade are basically no longer considered "airtight windows," and their sealing effect is similar to that of traditional old-style aluminum windows.
- Award/Basic Level: 30 Level: This is an entry-level airtight window that provides basic sealing and can block some wind, sand and dust, but its effect is still limited for environments that require high quietness or energy saving.
- High Standard/Standard Grade: Level 8: The most mainstream standard airtight window grade on the market, which can effectively reduce wind infiltration, significantly improve the energy efficiency of heating and cooling, and has a good auxiliary effect on sound insulation. Level 8 can provide a very excellent living quality.
- Top Standard/High Performance Grade: Level 2: CNS's highest airtightness standard. The windows have an extremely high degree of airtightness, effectively blocking airflow, dust, and moisture. Excellent sound insulation. Suitable for: high-rise buildings, windward locations, and areas near heavily polluted industrial areas.
Water tightness
This refers to the ability to block rain. The higher the value, the better it can withstand strong winds and heavy rain, and the stronger its ability to prevent rainwater from seeping into the room. Given Taiwan's frequent rain and typhoons, it's recommended to choose a unit with at least 35 kgf/m² for peace of mind .
- Basic (10-25 kgf/m²) : The most basic watertightness, suitable for general environments without special wind or rain. Provides basic protection during Taiwan's plum rain season or afternoon thunderstorms.
- Basic (25-35 kgf/m²) : This is the most common standard grade . For most buildings, this grade is sufficient to handle most rain and provides reliable waterproofing for the lower and middle floors.
- High Standard (Basic) 35～50 kgf/㎡ : This is the highest level of the CNS standard, used in mid-to-high-rise buildings and areas with frequent wind and rain. 50 kgf/㎡ can more effectively resist strong winds and heavy rains of typhoon level.
- Ultra-high standard (Basic): Greater than 50 kgf/m² : This level is required for super extreme environments.
Wind pressure resistance
kgf/㎡ refers to the wind force that a window can withstand per square meter of area, equivalent to the pressure of a few kilograms of weight, without damage. It is also known as the window's ability to resist typhoons. The higher the wind pressure resistance number, the stronger the window. If you live on a high floor or in an open area, it is best to choose a window with a wind pressure resistance of 280 kgf/㎡ or 360 kgf/㎡ .
280 kgf/㎡ means "can withstand the wind force of a 280 kg weight without being damaged".
- Basic/Low Standard 80-120 kgf/m²: Can withstand light typhoons (level 10 to 11 winds). This is the most basic wind pressure resistance capability, suitable for floors 1-3 and environments with buildings providing shelter, such as urban areas. However, this level of protection is relatively limited given Taiwan's frequent typhoon season.
- Winning/Standard Grade 160～240 kgf/㎡ : Can withstand moderate typhoons (level 12 to 14 winds) . This is the standard grade that best meets the needs of most residences. For people living in ordinary buildings, this wind pressure resistance can provide sufficient safety. It is the most balanced choice between performance and budget.
- High Standard/High Performance Grade 280～360 kgf/㎡ (or above) : Can withstand strong typhoons (level 15 to 17 winds), which is the highest safety level of " typhoon-proof window " standard. It can withstand the strong wind pressure of a severe typhoon , ensuring that the window will not deform and the glass will not break.
Sound insulation
The Ts value represents the reduction in noise levels in decibels (dB). The higher the number, the more noise is blocked, resulting in a quieter indoor environment. A Ts-30 can block most urban noise; if you live near a main road, go for Ts-35.
- Low Standard/Basic Level: Can reduce noise by 25 decibels (Ts-25) : This is the entry-level standard for soundproof windows, suitable for use in relatively quiet environments or residential areas where people are not so sensitive to noise. It can filter out some mid-to-high frequency noise. Ts-25 has limited effect on blocking low-frequency noise from cars and motorcycles .
- Standard/Medium Grade: Reduces noise by 30-35 dB (Ts-30 / Ts-35): The most mainstream and common choice on the market, achieving a good balance between performance and price. The Ts-35 provides noticeable noise reduction, generally reducing traffic noise to a level that does not affect daily life .
- High Standard/High Performance Grade: Reduces noise by 40 decibels or more (Ts-40+): The highest sound insulation standard, requires thicker laminated glass (8mm+8mm or more), professional window frame design. Ts-40+ is suitable for: elevated bridges, expressways, main roads, railway tracks, near airports, professional recording studios, music classrooms, etc.
Glass and structural design
Since 80% of a window is glass, glass design is very important. Then there are the window frame, airtight strips, and hardware. All of these together make a high-quality airtight window. The thicker the glass, the better the sound insulation. Laminated glass, double-glazed glass, and Low-E energy-saving glass are all improvements in glass structure. The following is a summary of our findings.
Low-E energy-saving glass
A new energy-saving and heat-insulating marvel: a thin layer of metal film is coated onto the glass. This film reflects the heat (infrared rays) and ultraviolet rays in sunlight without affecting the amount of light passing through. In summer, it can block heat from the outside, and in winter, it can prevent the loss of indoor heat, achieving the effect of "warm in winter and cool in summer". It can save a considerable amount of electricity bills and prevent furniture and floors from fading due to ultraviolet radiation. It has become a very popular energy-saving option in recent years and often appears on the list of windows facing west.laminated glass
A film is sandwiched between the two pieces of glass to minimize the vibration of noise.Multi-layer/Insulating Glass
There is an air layer between the two panes of glass, which can insulate against sound and heat. It can block heat in summer and keep you warm in winter, saving you a lot of money on air conditioning.Single-pane glass
For the most basic style, if you really want to choose one, the thickness should be at least 8mm or more.window frame
Whether a window can last a long time and whether it is airtight depends on these two small things: the mainstream window frame is made of aluminum alloy, so you need to check whether the window frame structure is stable and whether the thickness is sufficient.airtight strip
This is the key to airtightness. Remember to specify EPDM rubber material. EPDM is more durable and less prone to deformation than traditional PVC. Although it is a bit more expensive, it is definitely worth it.Hardware accessories
Handles, wheels, door latches... small hardware parts can directly affect how easy it is to open a window. Go to the store and try pushing and pulling it yourself to feel its weight and smoothness.
What are the different styles of airtight windows?
The most common type is the "sliding window," which slides back and forth. It takes up the least space, so it's frequently used in both living rooms and bedrooms. If you're concerned about noise or live near a road, you can choose a "push-out window," which opens outwards and closes very tightly, providing excellent sound insulation. There's also a type that can't be opened at all, the "fixed window," which offers the best lighting and views and is usually used in conjunction with other windows. There are also some special types, such as "top-and-bottom windows," which can be pushed up slightly for ventilation and rain protection. Then there are the highly functional "tilt-and-turn windows," which can open inwards and tilt for ventilation, making cleaning incredibly easy. If you want your home to feel spacious, the "folding window," which can be completely retracted like an accordion, is perfect, instantly transforming your balcony into an indoor space.

There are two methods for installing airtight windows: "dry" and "wet".
wet construction
Completely remove the old window frames and rebuild them with new cement. This provides the best waterproofing, but it will create a lot of dust in the house and take a relatively long time. It's more suitable for a new home or a major renovation.
Dry construction
Keep the old window frame and simply fit the new window onto it. The installation is super fast and clean, and can be done in a day. It's perfect for people who just want to replace their windows.

Recommended installation procedure for airtightness
Even good airtight windows need to be installed correctly to be effective. Here are some installation procedures and inspection tips. If you buy good windows but they are not installed properly, their effectiveness will be greatly reduced. Below are some procedures for installing airtight windows (soundproof windows). You can follow the installation process and check the items.
Installation process reference
- Discuss your needs: Talk to the manufacturer about your needs and budget.
- In-home measurement: The technician will come to your home to take precise measurements.
- Signing the contract: Once everything is confirmed, let's sign the contract!
- Schedule a time for installation: Once the windows are finished, schedule a time for installation.
- Check payment: After installation, carefully check that there are no problems before paying the final payment.
Acceptance Item Reference
- Is it installed straight? Check if the window frame is crooked.
- Is the seam filled? No matter what kind of filler is used, it should be full and without any holes.
- To ensure a neat and even application of silicone sealant, the edges should be smooth and free of bumps or dents.
- Check if the switch works smoothly: Try switching it on and off repeatedly to see if it gets stuck or doesn't work properly.
- Check for scratches: Inspect the window frame and glass for any damage.
- Is it clean? Finally, please ask the cleaner to clean up all the trash before leaving!
- Check if the drain holes are clear: There are drain holes in the track below the window. You can pour in a little water to test if the water drains smoothly. This simple action can prevent water from accumulating in the window frame during heavy rain in the future!
Frequently Asked Questions (Q&A) about Airtight Windows
Q1: How is the price of an airtight window calculated? What is the size of "一才"?A: Usually, the price is calculated in "cai" (才). "One cai" is roughly 30 cm x 30 cm. The total price includes the window frame, glass, hardware, and installation fees.
