When planning a roofing project, one of the most critical decisions is selecting the right polycarbonate sheet thickness. When you build a greenhouse, car shed, industrial structure, or skylight, the thickness of the sheet matters. It affects durability, insulation, weight, and cost.
At Jigar Plast, we understand how confusing it can be to choose between 4mm, 6mm, 10mm, or even thicker options. That’s why we’ve assembled this detailed guide to help you make an informed decision based on your project’s needs.
The thickness of a polycarbonate sheet affects:
Thinner sheets are more flexible and cost-effective but may not offer sufficient strength for heavy-duty applications. Thicker sheets are more durable and offer better insulation but come at a higher cost and weight.
Thickness | Common Use Cases |
4mm :- | Low-cost greenhouses, temporary covers |
6mm :- | Patios, pergolas, carports |
8mm :- | Residential roofs, awnings |
10mm :- | Industrial sheds, commercial roofing |
16mm+ :- | Skylights, cold storage, high-impact areas |
If you’re covering a greenhouse, nursery, or small garden shed, you’ll want a sheet that allows high light transmission and UV protection.
Outdoor shade structures need roofing that balances lightweight design with durability.
If you are installing polycarbonate for roofs, light domes, or skylights, you will want good insulation and impact resistance.
Larger structures require thicker sheets to handle weather, impact, and structural load.
For speciality roofing in cold rooms, factory partitions, or security enclosures, thickness matters even more.
When selecting the right thickness, think beyond just the structure. Consider:
Choosing the right polycarbonate roofing sheet thickness can make or break the efficiency, durability, and performance of your structure.
