Polycarbonate sheets have become a go-to material for a wide range of projects in Sri Lanka — from roofing and skylights to greenhouses and safety barriers. Their strength, transparency, and versatility make them highly attractive, but buying polycarbonate sheets isn’t as simple as picking the first one you see.
At Jeewa Plastic, we help first-time buyers, contractors, and business owners make smarter purchasing decisions by understanding the key factors that affect performance, durability, and cost.
Here’s what you need to know before buying polycarbonate sheets.
Why Polycarbonate Sheets Are So Popular in Sri Lanka
Before diving into the buying process, it’s important to understand why polycarbonate has become one of the most widely used plastic sheets in the local market:
- Impact Resistant: Almost unbreakable, making it safer and more durable than glass.
- Lightweight: Easy to transport, handle, and install.
- Weather Resistant: Perfectly suited for Sri Lanka’s intense sun, humidity, and monsoon rains.
- UV Protection: Many sheets come with UV coatings to resist yellowing and degradation over time.
- Excellent Light Transmission: Allows for clear or diffused natural light, ideal for both homes and commercial spaces.
Key Factors to Consider Before You Buy
1. Intended Application
Determine exactly where and how you plan to use the polycarbonate sheets:
- Greenhouses: Look for multi-wall polycarbonate for better insulation.
- Roofing & Skylights: Clear or tinted solid sheets work well.
- Safety Barriers & Partitions: Solid, impact-resistant sheets are recommended.
- Advertising & Signage: Lightweight, easy-to-print sheets are ideal.
Each application requires different sheet properties, thicknesses, and finishes.
2. Sheet Thickness
Thickness directly impacts strength, insulation, and price. Common thicknesses include:
- 2mm–3mm: Light duty, interior use
- 4mm–6mm: Outdoor roofing, skylights
- 8mm–10mm+: Greenhouses, industrial uses
Tip: Thicker sheets handle stronger winds and offer better insulation.
3. Type of Polycarbonate Sheet
There are two primary types:
- Solid Polycarbonate Sheets: Clear, glass-like appearance, ideal for windows, skylights, and barriers.
- Multiwall Polycarbonate Sheets: Hollow-layered design offering superior insulation for greenhouses and roofing.
Common Mistakes First-Time Buyers Make
Choosing the Wrong Thickness
Many buyers select sheets that are too thin for exterior applications, leading to faster damage. Match thickness to weather exposure and intended use.
Overlooking UV Coating
Without proper UV protection, polycarbonate sheets may discolor or weaken under constant sun exposure. Always confirm UV-treated sheets for outdoor use.
Focusing Only on Price
Low-cost polycarbonate may lack long-term durability or be prone to warping and yellowing. Balance price with certified material quality.
Buying Without Checking Supplier Credibility
Always source from reputable suppliers like Jeewa Plastic who provide product warranties, technical guidance, and consistent product quality.
