Taiwan's 10 Most Airtight Windows Recommended for 2025
How to choose airtight windows (soundproof windows)?
However, with so many airtight window brands on the market, it can be overwhelming. How do you choose? Don't worry, this article is your savior. We'll walk you through the key purchasing considerations (airtightness, watertightness, wind resistance, sound insulation, glass, structure, energy efficiency, and construction methods), the top 10 most popular airtight window brands, and installation precautions. We'll help you easily choose the right windows and create a quiet and comfortable dream home.
Airtight windows, soundproof windows, don't confuse them anymore
Many people's first question before purchasing is, "What's the difference between airtight and soundproof windows?" Remember this simple concept: "Soundproof windows are always airtight, but airtight windows don't necessarily offer superior soundproofing."
- Airtight windows: Their primary function is to seal, keeping out wind and rain. A qualified airtight window must meet the minimum requirements of the National Standard (CNS) for airtightness, waterproofing, wind resistance, and sound insulation. Essentially, they are an upgraded version of traditional aluminum windows.
- Soundproof Window:
This is the "Pro Max" version of the airtight window. It puts extra effort into sound insulation, usually using thicker glass (such as laminated glass), stronger window frames, and adding several layers of airtight strips. The goal is to isolate noise to the extreme.
Should I choose airtight windows or soundproof windows?
Airtight windows: If you just want to block the wind and rain and improve your quality of life, choosing good airtight windows will be enough.
Soundproof windows: But if your home is close to noise sources (such as main roads, markets, and schools), then spending a little more money on soundproof windows will definitely make you feel that the money is well spent.
Five key points to consider when choosing airtight windows (soundproof windows)
Master these five key points and you too can become a skilled window selector, avoiding being shortchanged. Understanding your windows' "physical inspection report": The National Standard (CNS) is like a window's ID card, with four important numbers that directly tell you its performance. When purchasing, feel free to ask the store to see the original manufacturer's inspection report; the data on it is the most accurate.
Airtightness
The numbers of the airtightness grade represent the amount of air leakage. The smaller the number, the less air leakage and the better the sound insulation effect . It is divided into four levels: 2, 8, 30, and 120. The smaller the number, the more severe it is, which means it is less likely to leak air. Generally, choosing levels 8 or 2 for a home is already a very good airtightness grade.
- Low Standard/Ventilation Grade: Grade 120 : This is the lowest standard of airtightness and allows for the most ventilation. Windows of this grade are generally no longer considered "airtight" and their sealing effect is similar to that of traditional, older aluminum windows.
- Winning bid/Basic level: 30 Level: This is the entry-level airtight window level, which can provide basic sealing effect and block some wind, sand and dust, but the effect is still limited for environments that pursue high quietness or energy saving.
- High standard/standard level: Level 8: The most mainstream standard airtight window level on the market, which can effectively reduce wind infiltration, significantly improve the energy efficiency of air conditioning and heating, and has a good auxiliary effect on sound insulation. Level 8 can provide very excellent living quality.
- Top mark/high performance level: 2 Level: CNS's highest airtightness standard, the window is very tight, can block airflow, dust, moisture to the greatest extent, and has good sound insulation effect. Suitable for: high floors, windward side, adjacent to industrial areas with serious air pollution
Watertightness
This refers to the ability to block rain. A higher value indicates greater resistance to strong winds and heavy rain, preventing rain from seeping into the home. Given Taiwan's frequent rain and typhoons, it's recommended to choose a floor with a rating of at least 35 kgf/㎡ .
- Basic: 10-25 kgf/㎡ : The most basic watertightness, suitable for general environments without special wind and rain, and can provide basic protection during Taiwan's rainy season or afternoon thunderstorms
- Basic: 25-35 kgf/㎡ : The most common standard grade . For the middle and lower floors of most buildings, this grade is sufficient to cope with most rain and provide reliable waterproofing protection.
- Basic: 35-50 kgf/㎡ : This is the highest level in the CNS specification and is used in mid- to high-rise buildings and areas with frequent wind and rain. 50 kgf/㎡ can more effectively withstand typhoon-level strong winds and heavy rains.
- Super high standard (Basic) greater than 50 kgf/㎡ : This level is required if it is a super extreme environment.
Wind pressure resistance
kgf/㎡ refers to the window's ability to withstand wind pressure of several kilograms per square meter without damage, and its ability to resist typhoons. The larger the wind pressure resistance number, the stronger it is. If you live on a high floor or in an open area, it is best to choose 280 kgf/㎡ or 360 kgf/㎡ .
280 kgf/㎡ means "withstanding wind force as if subjected to a 280 kg weight without being damaged."
- Low-level/basic grade: 80-120 kgf/㎡: Can withstand mild typhoons (force 10-11). This is the most basic wind resistance and is suitable for buildings on the first to third floors, such as those located in urban areas and sheltered by buildings. During Taiwan's frequent typhoon season, this grade offers relatively limited protection.
- Winning Bid/Standard Grade 160-240 kgf/㎡ : Can withstand moderate typhoons (force 12 to 14). This is the standard grade that best meets the needs of most residential buildings. For people living in ordinary buildings, this wind pressure resistance can provide sufficient safety and is the most balanced choice between performance and budget.
- High standard/high performance level 280~360 kgf/㎡ (or above) : can withstand strong typhoons (level 15 to 17 winds), is the highest safety level " typhoon-proof window " standard, can withstand the strong wind pressure of severe typhoons , to ensure that the windows will not deform and the glass will not break.
Sound insulation
The Ts value represents the decibel reduction (dB) of noise. The higher the number, the more noise is blocked, and the quieter the room. Look at the Ts value; the higher the number, the quieter it is. A Ts-30 will block out most urban noise. If you live near a major road, go all the way up to Ts-35.
- Low standard/basic level: can reduce 25 decibels (Ts-25) : This is the entry-level standard for soundproof windows. It is suitable for use in relatively quiet environments or residential areas that are not so sensitive to noise. It can filter out some mid- and high-frequency noise. Ts-25 has limited effect on blocking low-frequency noise such as cars and motorcycles .
- TS-30/TS-35 : 30-35dB noise reduction : The most popular and mainstream options on the market, offering a good balance between performance and price. TS-35 offers noticeable noise reduction, reducing the noise of ordinary traffic to a level that doesn't disrupt daily life .
- High Standard/High Performance: Reduces noise by 40 decibels or more (TS-40+): The highest standard of sound insulation requires thicker laminated glass (8mm+8mm or greater) and a professional window frame design. TS-40+ is suitable for applications such as overpasses, expressways, along major roads and railway lines, near airports, professional recording studios, and music classrooms .
Glass and structural design
Eighty percent of a window is glass, so glass design is crucial. Next in line are the window frame, airtight strips, and hardware accessories. Together, these elements create a high-quality, airtight window. The thicker the glass, the better the sound insulation. Laminated glass, insulating glass (multi-layered), and Low-E energy conservation are all improvements to glass structure. Here's our summary.
Low-E energy-saving glass
A new wonder for heat insulation and energy saving, this is a thin metal film coated on glass. This film reflects both thermal energy (infrared) and ultraviolet rays from sunlight without affecting the lighting. It keeps heat out in the summer and prevents heat loss in the winter, creating a "warm in winter, cool in summer" effect. This saves considerable electricity bills and prevents furniture and flooring from fading due to UV radiation. It has become a very popular energy-saving option in recent years and often appears on lists for west-facing windows.Laminated glass
There is a layer of film sandwiched between the two pieces of glass to minimize the vibration of noise.Composite/insulating glass
There is an air layer between the two pieces of glass, which can provide sound insulation and heat insulation, block heat in summer and keep warm in winter, helping you save a lot of money on air conditioning.Single-layer glass
For the most basic style, if you really want to choose one, the thickness must be at least 8mm.window frame
Whether the windows can be used for a long time and whether they are dense enough depends on these two small places. The mainstream window frames are made of aluminum alloy, and it depends on whether the window frame structure design is stable and whether the thickness is sufficient.Airtight strips
This is the key to determining airtightness. Remember to specify EPDM rubber material. EPDM is more durable and less likely to deform than traditional PVC. Although it is a bit more expensive, it is definitely worth it.Hardware accessories
Handles, wheels, door latches...small hardware parts will directly affect whether you can open the window. Go to the store and try pushing and pulling them yourself to feel the weight and smoothness.
What are the airtight window styles?
The most common type is the "horizontal sliding window", which is the type that can be slid left and right. It takes up the least space, so it is commonly used in both living rooms and bedrooms. If your home is afraid of noise, or you live on the side of the road, you can choose a "sliding window", which slides outward and closes very tightly, with excellent sound insulation. There is also a type of "fixed window" that cannot be opened at all, which is the best for lighting and scenery, and is usually paired with other windows. There are also some special models, such as "up and down hanging windows" that can be pushed upward to open a small gap for ventilation and rain protection. There are also "inward-opening and tilting windows" with super functions that can be opened inward and tilted for ventilation, which are super easy to clean. If you want your home to feel super open, the "folding windows" that can be folded up like an accordion are the most suitable, turning the balcony into an indoor space in a second.

There are two methods for constructing airtight windows: dry and wet.
Wet construction
Remove the old window frames entirely and replace them with new cement. This method offers the best waterproofing, but it can create a lot of dust and take a long time to complete. It's best suited for new homes or major renovations.
Dry construction
Keep the old window frames and simply install the new windows. This is a super quick and clean installation that can be completed in just one day. It's perfect for those who simply want to replace their windows.

Recommendations for airtight installation process
Good airtight windows are only useful if they are installed correctly. Here are some installation procedures and acceptance tips. If you buy good windows but don't install them properly, the effect will be greatly reduced. The following are some procedures for installing airtight windows (soundproof windows). You can refer to the installation procedures and acceptance items.
Installation process reference
- Talk about needs: Talk to the manufacturer about your needs and budget.
- Measurement at home: The master will come to your home for precise measurement.
- Sign the contract: Once everything is confirmed, sign the contract!
- Schedule construction: After the windows are completed, schedule an installation time.
- Check and pay: After installation, check carefully and make sure there are no problems before paying the balance.
Acceptance Project Reference
- Is it installed correctly: Check whether the window frame is crooked.
- Are the seams filled: No matter what type of filler is used, the seams must be full and have no holes.
- Whether the silicone is applied beautifully or not: The glue on the edges should be smooth and without any bumps or scars.
- Switch on and off smoothly: Turn on and off repeatedly to see if it gets stuck or does not operate smoothly.
- Are there any scratches? Check the window frame and glass for damage.
- Is it cleaned up? Finally, please ask the master to clean up all the garbage before leaving!
- Is the drainage hole unblocked? The window track below will have drainage holes. You can test it by pouring a little water in to see if the water can drain out smoothly. This small action can prevent water from accumulating in the window frame during heavy rain in the future!
Airtight Window FAQs (Q&A)
Q1: How is the price of an airtight window calculated? How big is a "cai"?A: Prices are usually calculated in cai. A cai is roughly 30cm x 30cm. The total price includes the window frame, glass, hardware, and installation.
Q2: Can old windows be directly replaced with airtight windows?
A: Of course! If you don't want to mess up your walls, you can opt for the dry construction method. It's super quick and clean, and can be done in a day.
Q3: Do airtight windows require special maintenance?
A: It's easy! Simply wipe the window track with clean water to remove any dust. Remember not to use harsh detergents.
Q4: Where can I find a reliable manufacturer?
A: The safest way is to go directly to the dealers who are certified on the brand's official website. They are all guaranteed by the original manufacturer, and the construction quality and after-sales service are relatively guaranteed.
Q5: Can I buy airtight windows online?
A: Absolutely not! Airtight windows are custom-made, so you must have a technician come to your home to measure your dimensions. Buying them online and getting the wrong size or having them fail to fit can be a real hassle.
