Which Is Better Glass VS Polycarbonate Sheet For Skylight?

Strength and Durability:

Polycarbonate: Polycarbonate sheets are known for their exceptional strength. They are approximately 200 times stronger than glass and virtually unbreakable, making them highly resistant to impact and shattering .

Glass: While glass is rigid and durable, it is more prone to breakage and shattering compared to polycarbonate. It requires additional supporting structures to ensure safety and prevent accidents .

Weight:

Polycarbonate: Polycarbonate sheets are significantly lighter than glass. They weigh about six times less than glass, making them easier to handle and install.

Glass: Glass is heavier, which can make installation more challenging and require additional structural support.

 

 

 

Insulation and Energy Efficiency:

Polycarbonate: Polycarbonate sheets provide superior insulation properties, offering better thermal efficiency compared to glass. This can result in lower energy costs by reducing heat transfer and maintaining a more stable indoor temperature .

Glass: Glass has lower insulation properties compared to polycarbonate, which can lead to heat loss or gain, potentially increasing energy consumption for heating or cooling.

Light Transmission:

Polycarbonate: Polycarbonate sheets allow excellent light transmission, often surpassing glass in terms of clarity and brightness. They can provide a more diffused and even distribution of natural light, reducing the need for artificial lighting during the day.

Glass: Glass also allows light transmission, but it may have slight distortions or reflections that can affect the clarity and distribution of light.

 

 

 

Cost:

Polycarbonate: Polycarbonate sheets are generally more cost-effective than glass, especially when considering their durability, impact resistance, and energy efficiency. They offer a good balance between performance and affordability.

Glass: Glass tends to be more expensive, especially if specialized types such as laminated or tempered glass are required for safety purposes .

In summary, both glass and polycarbonate sheets have their advantages and considerations for skylights. Polycarbonate sheets offer superior strength, impact resistance, lighter weight, better insulation, and cost-effectiveness. On the other hand, glass provides a traditional aesthetic appeal and may be preferred for specific design requirements. Ultimately, the choice between the two materials depends on factors such as budget, desired performance, safety considerations, and aesthetic preferences.
