Polycarbonate Roofing Sheets

A polycarbonate roofing sheet is a lightweight, shatter-resistant plastic sheet made from polycarbonate resin. It is widely used in roofing, skylights, canopies, and greenhouses because it allows high light transmission like glass but with far greater impact resistance. Available in solid, multiwall, and corrugated designs, these sheets are durable, UV-protected, and easy to install.

Polycarbonate roof panels are about 200 times stronger than glass of the same thickness. Unlike glass, they do not shatter on impact, making them safer in high-traffic or storm-prone areas. They are also lightweight, reducing structural load, while still maintaining excellent clarity and weather resistance.

The main types include solid (monolithic) sheets for clarity and strength, multiwall sheets for insulation and diffusion, and corrugated/profiles sheets for easy roof integration. Specialty options like prismatic or hard-coated panels are also available for glare control, scratch resistance, or flame retardance. Each type serves specific architectural and industrial needs.

Yes, polycarbonate roofing sheets are designed to resist heavy rain, hail, wind, and even snow loads when installed correctly. Their UV-protective coating prevents yellowing and brittleness under sunlight, while their impact strength ensures long-term reliability even in challenging climates. Proper slope and fastening are crucial for performance.

The ideal thickness depends on the application. For small skylights or window glazing, 2–6 mm solid sheets are sufficient. For pergolas or greenhouses, 6–10 mm multiwall sheets are common. For heavy-duty roofing, 10–12 mm or corrugated sheets may be recommended. Thicker sheets improve strength but add cost and weight.

Yes, solid polycarbonate sheets are nearly as transparent as glass, allowing up to 90% light transmission. Multiwall sheets diffuse light slightly, reducing glare but still providing excellent daylight. Tinted or colored options are also available for shading, privacy, or decorative effects. This makes them versatile for different environments.

Polycarbonate is stronger and more impact-resistant than Perspex (acrylic). Acrylic may offer slightly better scratch resistance and clarity, but it is brittle and prone to shattering under heavy impact. For roofing and safety-critical uses, polycarbonate is usually the preferred choice due to its toughness and weather resistance.

Yes, polycarbonate sheets can be cut with fine-toothed saws and drilled with standard high-speed steel drill bits. Holes should be slightly larger than the fastener diameter to allow thermal expansion. Always use clean, sharp tools to prevent cracking, and avoid flame cutting or extreme heat methods.

High-quality sheets with proper UV protection, like Anand Plastics’ PC Lite, do not yellow easily. Lower-grade or non-UV-coated sheets may discolor after prolonged sun exposure. Correct orientation of the UV-coated side during installation is critical to ensure long-lasting clarity and appearance.

Polycarbonate has a good fire performance rating and self-extinguishes once the flame source is removed. However, specific fire-retardant grades are available for projects with strict fire safety codes. Always check local building regulations and request flame-rated products where necessary.

Yes, multiwall polycarbonate sheets are ideal for greenhouses. They provide excellent light diffusion, high transmission, and better insulation than glass. This helps regulate temperature, prevents plant scorching, and reduces energy costs. 4 mm–10 mm multiwall sheets are most commonly used for greenhouse roofing and walls.

With proper installation and care, polycarbonate roofing sheets can last 15–20 years or more. Their UV-protected surface resists degradation, while their impact strength ensures durability. Regular cleaning and proper sealing at edges further extend lifespan, making them a cost-effective choice compared to glass or fiberglass.

Yes, multiwall sheets provide good thermal insulation due to their hollow chambers that trap air. This reduces heat transfer, making them effective for greenhouses, conservatories, and pergolas. Solid sheets have less insulation but can be combined with coatings or double glazing for better performance.

Polycarbonate sheets are much lighter than glass, often weighing less than half while offering greater impact strength. This reduces transportation costs, makes installation easier, and lowers structural load requirements. Their lightweight nature also allows longer sheets (like 3×100 ft or 7×100 ft rolls) for seamless installation.

Cleaning requires only mild soap and water with a soft cloth or sponge. Avoid abrasive cleaners, ammonia-based solutions, or solvents like acetone, which can damage the surface. Periodic cleaning prevents dirt buildup and ensures maximum light transmission. Always clean gently to avoid scratches.

Polycarbonate sheets come in a wide range of colors including transparent (clear), opal white, black, green, bronze, and more. Colored sheets help reduce glare, filter sunlight, or provide aesthetic appeal. Anand Plastics offers multiple color options under the PC Lite brand for both functional and decorative uses.

Installation involves cutting sheets to size, orienting the UV-protected side outward, and fastening them with screws and rubber washers. Overlaps and flashings are used to prevent leaks. For multiwall sheets, ends are sealed with vented tape and covers. Always allow for thermal expansion by drilling oversized holes.

Anand Plastics offers a customer-friendly MOQ of just 2 sheets for polycarbonate roofing sheets. This is ideal for homeowners, small projects, or replacement needs. For large industrial buyers, bulk orders are also available with optimized pricing and logistics support.

Anand Plastics supplies PC Lite polycarbonate sheets in thicknesses from 1.2 mm to 12 mm. Sheet sizes include long-run options like 3×100 ft and 7×100 ft, along with custom cut-to-size solutions. This flexibility makes it easy to match project requirements, reduce wastage, and simplify installation.

Anand Plastics stands out for its PC Lite brand, offering consistent quality, UV protection, multiple thicknesses, and color choices. With low MOQ, custom sizing, and expert technical guidance, customers benefit from both product reliability and professional support. The company’s focus on durability, cost-efficiency, and service makes it a trusted partner for all roofing needs.
