Multiwall Polycarbonate Sheet

A multiwall polycarbonate sheet is a lightweight, high-strength thermoplastic sheet made with multiple internal layers and air chambers. These layers improve thermal insulation, impact resistance, and durability while allowing excellent light transmission, making it ideal for roofing, skylights, and greenhouses.

Multiwall polycarbonate sheets are widely used for industrial roofing, warehouses, greenhouses, skylights, parking sheds, walkways, commercial buildings, and residential canopies due to their strength, insulation, and long lifespan.

The main difference is structure and performance. Polycarbonate multiwall sheets have multiple internal layers that provide better insulation, higher strength, and noise reduction, whereas single wall sheets are flat and offer lower insulation and load-bearing capacity.

The ideal thickness depends on application:

• 6mm for light roofing and residential use
• 8–10mm for industrial and commercial roofing
• 12mm for heavy-duty and large-span structures

Choosing the right thickness ensures safety, durability, and cost efficiency.

The multiwall polycarbonate sheet price list in India varies based on thickness, size, color, and quantity. Indicative pricing generally starts from ₹87 per kg onwards or ₹4400 per sheet onwards, depending on specifications.

The multiwall polycarbonate sheet price list depends on:

• Sheet thickness
• Sheet size
• Color option
• UV coating quality
• Brand and material grade
• Order quantity

Higher thickness and UV protection usually increase the price.

Yes, polycarbonate multiwall sheets are highly heat resistant. Their internal air chambers reduce heat transfer, making them suitable for hot climates while maintaining comfortable indoor temperatures.

With proper installation and minimal maintenance, a high-quality multiwall polycarbonate sheet can last 10–20 years or more, depending on exposure conditions and UV protection quality.

Yes, multiwall polycarbonate sheets are waterproof when installed correctly using proper profiles and sealing methods. Their design helps prevent water leakage and withstand heavy rainfall.

In most applications, a multiwall polycarbonate sheet is better than glass because it is lighter, far more impact resistant, provides better thermal insulation, and is safer to install and use, especially in industrial and outdoor environments.
