How much does it cost to replace a piece of curtain wall glass?

Due to different environments and glass characteristics, glass curtain walls are prone to cracking, breaking, or leaking in extreme weather such as hot summer or storms. Replacing curtain wall glass is not only troublesome, but also costly. Today, the editor of Zhongdong Curtain Wall will tell you how much it costs to replace a piece of curtain wall glass, so that you will no longer be confused about the price of curtain wall glass replacement.

1. The cost of the glass itself: Don’t just look at the area, the material is the key!
Many people think that the price of glass is “calculated by square meter”, but in fact, the material and craftsmanship vary greatly. The following is a comparison of the “value” of common curtain wall glass:

1. Ordinary tempered glass
Price: 1,000-2,000 yuan per square meter
Applicable scenarios: low-rise buildings, residential or commercial buildings without special requirements.
Disadvantages: If broken, it will become granular, which has certain safety hazards.

2. Laminated glass (intermediate laminated layer)
Price: 1800-3000 yuan per square meter
Applicable scenarios: high-rise buildings, shopping malls or places where sound insulation is required.
Advantages: If broken, it will be glued and will not fall off, and it is highly safe.

3. Low-E coated glass (heat insulation and UV protection)
Price: 1800-3000 yuan per square meter
Applicable scenarios: office buildings, hotels and other buildings with high energy-saving requirements.
Note: The coating process is complicated, and the larger the size, the more expensive it is.

Summary: Ordinary glass may cost 500 yuan, but if it is a large glass made of special materials, the material cost can easily exceed 10,000 yuan!

2. Glass curtain wall installation cost
The installation fee is the part that really widens the gap! The higher the floor and the greater the difficulty, the cost will double.

1. Low-rise (13 floors)
Labor cost: 300-800 yuan/day (2 people working)
Equipment: scaffolding or elevator can be used, equipment rental fee is about 500 yuan.
Total cost: about 800-1500 yuan.

2. Middle and high-rise (4-10 floors)
Labor cost: 800-1500 yuan/day (professional high-altitude operation master required)
Equipment: A small crane may be required, with a rental fee of 2000-4000 yuan/day.
Total cost: about 2000-4000 yuan.

Others: Road closure and protective netting may be required, with an additional charge of 2000-5000 yuan.
Total cost: easily over 10,000 yuan!

Real case: A 30-story office building replaced a 5-square-meter Low-E glass, the crane rental fee was 7,000 yuan + labor fee was 4,000 yuan + material fee was 12,000 yuan, and the total cost exceeded 23,000 yuan!

3. Additional costs: These “small amounts” can also exceed the budget!
Do you think that materials + installation are enough? These hidden costs will make you pay more every minute:

1. Dismantling and cleaning fees
If the old glass is broken, clean up the fragments and residual glue: 300-800 yuan.
The frame needs to be repaired if it is rusted or deformed: 500-2000 yuan.

2. Transportation fee
Ordinary glass: 200-500 yuan (in-city transportation).
Extra large glass: requires customized wooden boxes + special car transportation, which may be 1000-3000 yuan.

4. Regional differences: The difference between first-tier cities and small county towns can be double!
Labor costs and material costs vary from place to place:
First-tier cities (
Labor costs: 800-1500 yuan/person/day
Material costs: 10%-20% higher than second- and third-tier cities.

Second- and third-tier cities
Labor costs: 500-800 yuan/person/day
Material costs: ordinary glass is 50-100 yuan cheaper per square meter.

Small county or township
Labor costs: 300-500 yuan/person/day
But you may not be able to find a professional team, and you need to transfer people from other places, which is more expensive!

4. Pit avoidance guide: saving money ≠ safety!
1. Don’t be greedy and use inferior glass
Low-priced glass may have bubbles and impurities, and it is easy to explode in the later stage.
Be sure to check the “3C certification” and quality inspection report of the glass.

2. A contract must be signed for high-altitude operations!
Clarify responsibilities: Who will compensate if the glass is damaged or falls during installation?
Check the team’s qualifications: whether they hold a high-altitude work permit and whether the insurance is complete.

3. The measurement size must be accurate
An error of more than 3 mm may result in failure to install, and the rework fee is more expensive than the glass!

VI. Ultimate advice: ask more questions, compare more, and don’t rush to decide!
1. Get quotes from at least 3 local merchants and compare the material and labor details.
2. Request on-site measurement to avoid “remote valuation” errors.
3. Leave 10% of the budget as an emergency reserve to prevent midway price increases.

In short, replacing curtain wall glass is not a trivial matter, and the cost may range from thousands to tens of thousands. The key is to choose the right material and find a reliable team according to your own situation. It is better to spend more money than to joke about safety!
