Description
Clear Multiwall Polycarbonate Sheet is available in 6mm thickness with a standard sheet size of 48" × 96". For projects requiring exact dimensions, we offer custom cut clear multiwall polycarbonate in any size up to 48" × 96".
Clear Multiwall Polycarbonate features a hollow, ribbed structure with multiple walls that provide exceptional insulation and impact resistance. Also known as twinwall or double-wall polycarbonate, this lightweight material offers superior thermal efficiency compared to solid sheets while maintaining excellent light transmission. The internal ribs create air pockets that insulate against heat loss and reduce energy costs, making it ideal for greenhouses, skylights, and covered structures.
Virtually unbreakable - up to 200 times stronger than glass - while weighing significantly less, this material diffuses light evenly to reduce glare and hot spots. UV-protected on both sides to prevent yellowing and degradation, multiwall polycarbonate maintains clarity and strength for years. Easy to install and available in various thicknesses and wall configurations, it's the smart choice for energy-efficient glazing, patio covers, and protective applications.

Frequently Asked Questions
What's the difference between multiwall and solid polycarbonate?
Multiwall (also called twinwall or double-wall) polycarbonate has a hollow structure with internal ribs that create insulating air pockets. This provides better thermal efficiency and light diffusion than solid sheets. Solid polycarbonate offers better optical clarity and is stronger, but multiwall is more energy-efficient and lighter. Choose multiwall for greenhouses and roofing, solid for windows and applications requiring maximum clarity.
How much insulation does multiwall polycarbonate provide?
Multiwall polycarbonate provides significantly better insulation than single-layer materials. The R-value varies by thickness and number of walls - twinwall typically offers R-1.5 to R-2.0, while thicker triwall or multiwall panels can reach R-2.5 or higher. This makes it excellent for reducing heating and cooling costs in greenhouses and covered structures.
How do I install multiwall polycarbonate sheets?
Multiwall polycarbonate installs using specialized profiles and fasteners designed for the material. The hollow channels must run vertically to allow moisture drainage. Use proper sealing tape to close the ends and prevent moisture/insect entry. Pre-drill holes larger than fasteners to allow for thermal expansion. Professional installation is recommended for large projects to ensure proper weatherproofing.
Will multiwall polycarbonate yellow over time?
Quality multiwall polycarbonate with UV protection on both sides resists yellowing for 10-15 years or more. The UV coating prevents degradation from sun exposure. Unprotected or low-quality panels may yellow within 2-3 years. Always choose UV-protected multiwall polycarbonate for outdoor applications to ensure long-term clarity and performance.
