Rigid-structured sheets for superior thermal insulation and light transmission

SUNLITE multiwall polycarbonate sheets feature a variety of light transmission options and provide excellent thermal insulation. With at least two walls and connective ribbing, the sheets reduce thermal transfer, delivering a more energy efficient solution than singe-layer sheets.
The unique design of SUNLITE also results in a rigid, impact-resistant sheet that’s significantly lighter in weight than solid polycarbonate, acrylic, or glass sheets.  

Popular applications of SUNLITE include exterior roofing, glazing, wall or building cladding, as well as interior partitions and POP displays.
