When sourcing windows for residential, commercial, or industrial projects, one of the most common questions buyers ask is: What are the different window glass types, and how much do they cost?
The answer depends on a number of factors such as safety, energy efficiency, climate, and project budget. Buyers know better what they're buying and what to expect and don't get surprised by having to pay for features they don't want or need.
In this guide, we cover the most popular types of window glass, what they are used for and what factors affect the cost.
1. Float Glass – The Most Economical Choice
Float glass is the standard glass used in many residential windows. It offers excellent clarity and is suitable for applications where high safety or insulation is not required.
Advantages
Affordable price
Smooth and transparent surface
Easy to process into other glass products
Typical Applications
Interior windows
Picture frames
Furniture
Basic residential windows
Estimated Price
US$4–10 per square meter (depending on thickness and order quantity)
If you need your project to be more cost-effective as opposed to insulating or security, float glass is usually the best option.
2. Tempered Glass – Enhanced Safety
Tempered glass is processed by heat treating ordinary glass to make it about four to five times stronger. It breaks into small blunt pieces rather than dangerous sharp shards.
This is why tempered glass is the favored glass for the newer homes."
Advantages
High impact resistance
Better thermal resistance
Meets international safety standards
Typical Applications
Doors
Balcony windows
Shower enclosures
Commercial buildings
Estimated Price
US$12–35 per square meter
3. Laminated Glass – Maximum Security
Laminated glass is made from two or more layers of glass with a PVB or SGP interlayer.
The glass stays attached to the interlayer even when broken, which greatly enhances safety and security.
Advantages
Excellent security
UV protection
Noise reduction
Hurricane-resistant options available
Typical Applications
High-rise buildings
Schools
Airports
Banks
Luxury homes
Estimated Price
US$20–60 per square meter
4. Insulated Glass (Double Glazing)
Insulated Glass Units (IGUs) are manufactured using two or three panes separated by air or argon gas.
They significantly improve energy efficiency and indoor comfort.
Advantages
Lower energy bills
Better sound insulation
Reduced condensation
Improved thermal performance
Typical Applications
Residential windows
Office buildings
Hotels
Green buildings
Estimated Price
US$25–80 per square meter
Although the initial investment is higher, insulated glass often reduces long-term operating costs.
5. Low-E Glass – Energy Saving Solution
Low-E (Low Emissivity) glass features a microscopic coating that reflects heat while allowing natural light to enter.
It has become one of the most popular choices in energy-efficient construction.
Advantages
Excellent thermal insulation
UV protection
Comfortable indoor temperature
Lower HVAC costs
Typical Applications
Energy-efficient buildings
Villas
Office towers
Passive houses
Estimated Price
US$30–90 per square meter
What Factors Affect Window Glass Prices?
Several factors influence the final cost:
Glass thickness (4mm, 5mm, 6mm, 8mm, 10mm, etc.)
Glass size and dimensions
Processing requirements
Coating technology
Quantity ordered
Packaging method
Shipping destination
International freight costs
For wholesale purchasers, the unit price is most often adjusted when the quantity ordered increases.
How to Choose the Right Window Glass
Prior to ordering, you might want to ask yourself the following questions:
Is safety your top priority?
Does your local climate require better insulation?
Do you need soundproof performance?
What is your target budget?
Which building standards must be met?
Answering these questions helps narrow down the most suitable glass type for your project.
