Overview
Twin-wall polycarbonate sheets are light, strong, and thermally efficient glazing panels.
Songxia sheets use virgin SABIC LEXAN™ or Covestro MAKROLON® resin with a co-extruded UV layer for long outdoor life.
Light Weight & Strength
At only one-fifteenth the weight of glass, the panels are easy to handle and install.
The twin-wall structure gives high stiffness, helping the sheet resist wind loads and impact.
Thermal Insulation
The air gap between the two walls lowers the heat-transfer coefficient (K-value) and cuts heating and cooling demand.
Impact Resistance
Material toughness is about 250 times that of glass, providing reliable protection against hail, debris, and accidental knocks.
UV Protection
A co-extruded cap layer blocks more than 98 % of damaging UV radiation, preventing yellowing and surface degradation.
Environmental & Design Flexibility
Sheets are recyclable and contain no harmful additives. Standard clear, opal, blue, green, and brown colors are available, along with custom tints and surface options such as anti-fog or anti-static.
Typical Applications
- Greenhouses and garden shelters
- Skylights and daylighting roofs
- Noise barriers along roads and railways
- Carports, canopies, and walkway covers
- Machine guards and protective screens
With a balance of low weight, thermal performance, and durability, Songxia twin-wall polycarbonate sheets suit municipal, residential, and commercial projects that need clear, tough, and energy-saving glazing.
