What is the difference between Sunlite Twinwall and Sunpal Multi polycarbonate roofing systems?

When it comes to choosing polycarbonate sheets for your roofing or cladding needs, there are two popular options available in the market - Sunlite Twinwall and Sunpal Multiwall. Both of these products offer excellent durability, light transmission, and thermal insulation properties, making them suitable for a wide range of applications. However, there are some key differences between the two that you need to know before making a decision. In this blog post, we will compare Sunlite Twinwall and Sunpal Multiwall polycarbonate sheets to help you make an informed choice. 

1. Structure: 

Sunlite Twinwall polycarbonate sheets have a two-layered structure with a hollow center, making them lightweight yet strong. On the other hand, Sunpal Multiwall sheets have a multi-layered structure with a minimum of three walls, making them even stronger and more durable than Sunlite Twinwall sheets. 

2. Light Transmission: 

Both Sunlite Twinwall and Sunpal Multiwall polycarbonate sheets offer excellent light transmission properties. However, Sunpal Multiwall sheets have 10-15% higher light transmission than Sunlite Twinwall sheets due to their multi-layered structure. 

3. Thermal Insulation: 

Both Sunlite Twinwall and Sunpal Multiwall polycarbonate sheets offer excellent thermal insulation properties, making them ideal for applications where temperature control is important. However, Sunpal Multiwall sheets have slightly better insulation properties than Sunlite Twinwall sheets, thanks to their multi-layered structure. 

4. Fire Rating: 

Sunlite Twinwall polycarbonate sheets have a Class B fire rating, which means they are self-extinguishing and have a low-flammability rating. On the other hand, Sunpal Multiwall sheets have a Class A fire rating, which means they are highly fire-resistant and non-combustible. 

5. Durability: 

Both Sunlite Twinwall and Sunpal Multiwall polycarbonate sheets are highly durable and can withstand extreme weather conditions. However, Sunpal Multiwall sheets are more durable than Sunlite Twinwall sheets due to their multi-layered structure and superior impact resistance. 

6. Cost: 

Sunlite Twinwall polycarbonate sheets are more affordable than Sunpal Multiwall sheets, making them a popular choice for budget-conscious consumers. However, Sunpal Multiwall sheets offer superior performance and durability, making them a more cost-effective option in the long run. 

In conclusion, both Sunlite Twinwall and Sunpal Multiwall polycarbonate sheets offer excellent properties for various applications. However, if you are looking for superior light transmission, thermal insulation, and impact resistance, then Sunpal Multiwall sheets are the way to go. On the other hand, if you are looking for an affordable option that still offers decent performance, then Sunlite Twinwall sheets will suffice. Ultimately, the choice comes down to your specific requirements, budget, and preferences.
