How is the glass curtain wall priced?

You must be curious about how the glass curtain wall is priced. Today, Middle East Curtain Wall will talk to you about the pricing of glass curtain walls. I hope it will be helpful to you.

1. Glass and frame: “multiple choice” of basic materials

1. Types of curtain wall glass

Ordinary glass is 80-120 yuan per square meter:

Tempered glass (safety upgrade): the price doubles to 160-240 yuan, and it will break into particles without hurting people

Laminated glass (typhoon protection): PVB film in the middle, 12mm thick starts at 500 yuan/㎡

Low-E glass (heat insulation and sun protection): equivalent to applying “sunscreen” to the glass, 300-800 yuan/㎡

Ultra-white glass (beauty): as transparent as a mobile phone screen, the price jumps directly to 1,000 yuan +/㎡

2. Metal frame: Aluminum is also divided into different grades

Aluminum alloy profiles are like the skeleton of the human body. Common ones are:

Ordinary aluminum, sufficient but easy to oxidize

Fluorocarbon sprayed aluminum (strong weather resistance): 30% more expensive, but can be used for 20 years without fading
Stainless steel frame (for super high-rise): The price is three times that of aluminum, but it can withstand a force 12 gale

2. Design style: The cooler the shape, the more painful it is to your wallet

1. Flat surface vs. curved surface: The processing fee is three times different
The glass curtain wall with a flat surface is the cheapest, but it will cost money if you play with the shape:
2. Structural system: The assembly method determines the value
Framed glass curtain wall: Workers assemble on-site, 1200-1800 yuan/㎡
Unitized glass curtain wall: Factory prefabricated and shipped in one piece, 2500-3500 yuan/㎡

3. Construction site: “Money-burning moment” of high-altitude work

1. For every 100 meters increase in height, the cost increases by 20%
When installing curtain walls on a 50-meter-high building, workers can work with safety belts on. But when it is over 300 meters:
A special hanging basket is required, and the daily rental fee starts at 2,000 yuan
When it encounters strong winds, all workers stop working, and the construction period is delayed, resulting in a loss of 50,000 yuan per day

IV. Hidden consumption: pitfalls that will not be written on the quotation sheet

1. Accidents during transportation
Ordinary trucks transport glass: the breakage rate is about 5%, and a truckload of 100,000 yuan of goods may be thrown away for 5,000 yuan

2. Price game of after-sales service
Company A quoted a low price but only guaranteed for 2 years. As a result, the rubber strip aged and leaked in the third year, and the maintenance fee was enough to install half a layer of new curtain wall
Company B is 15% more expensive but provides 10 years of maintenance, and sends people to check twice a year, which is more cost-effective

V. Tips for saving money: spend money on the blade

1. Mix and match materials: Don’t save money on face projects
Use ultra-clear glass for the main facade and ordinary glass for the side
Choose laminated glass for low floors to prevent collision, and use hollow glass for high floors to keep warm

2. Design optimization: less corner cutting and less digging
Square glass is 30% cheaper than special-shaped glass

The window position is aligned with the floor to reduce special hardware

3. Construction timing: avoid peak season to get bargains

Construction in the off-season in winter can reduce labor costs by 20%

Construction is carried out simultaneously with civil engineering to save scaffolding rental fees

In the final analysis, the pricing of glass curtain walls is like custom-made suits – it depends on the size of the body and the depth of the wallet. Ordinary office buildings do not need to pursue ultra-clear glass, but coastal high-rise buildings must not save on safety. The key is to focus on the characteristics of the project: commercial complexes need to be beautiful, office buildings focus on energy saving, and residential projects must control noise.
