Comparison with Alternatives
vs. 8mm Solid Sheet
50% lighter, 35% better thermal insulation, slightly less light transmission
vs. 6mm Hollow Sheet
20% more rigid, 15% better insulation, similar weight
vs. 10mm Hollow Sheet
20% lighter, slightly less insulation, lower cost
vs. Glass (8mm)
1/16 the weight, 200x impact resistance, better insulation
Key Features & Benefits
1. Exceptional Thermal Insulation
The multi-chamber structure creates air pockets that provide excellent thermal insulation, reducing heating and cooling costs by up to 30% compared to single-layer materials. The 8mm thickness offers optimal balance between insulation value and cost-effectiveness.
2. High Strength-to-Weight Ratio
Despite its lightweight (approximately 1.6 kg/m²), 8mm hollow polycarbonate offers remarkable strength and can withstand heavy snow loads (up to 1.5 kN/m²) and high wind pressures.
3. Excellent Light Transmission
Clear sheets transmit 80-82% of natural light while diffusing it to reduce shadows and hotspots. Opal/white versions provide soft, evenly distributed daylight ideal for workspaces.
4. Easy Installation & Fabrication
Can be cut with standard woodworking tools
Cold-bendable for curved structures
Compatible with standard polycarbonate installation systems
Pre-drilled holes for expansion-contraction movement
5. Weather & UV Resistance
Co-extruded UV protection ensures:
No yellowing or embrittlement for 10+ years
Maintained mechanical properties
Protection for interior spaces from harmful UV rays
Typical Applications
Roofing & Cladding
Industrial skylights
Warehouse roofing
Carport and patio covers
Swimming pool enclosures
Agricultural greenhouses
Partitions & Enclosures
Factory partitions
Security barriers
Sports area enclosures
Sound barriers (with special acoustic grades)
Balcony and terrace glazing
Specialty Applications
Signage backing
Exhibition displays
Protective machine covers
Solar panel covers
Noise reduction screens
Installation Guidelines Summary
Support Structure: Maximum 750-900 mm spacing for rafters/purlins

Sealing: Always use proper polycarbonate-compatible tapes and sealants
Fastening: Use thermal washers and oversize drill holes
Cleaning: Mild soapy water only; avoid abrasive materials
Orientation: Always install with UV-protected side facing outward
