SINHAI 10-Year warranty greenhouse Hollow Polycarbonate Roof Sheet
Hollow polycarbonate sheet is also named as a structural polycarbonate,cellular polycarbonate,channel polycarbonate.
Light transmittance up to 88%,This twin wallvstructure creates insulating air spaces that help reduce thermal energy penetration, resulting in a cooler area in the summer and a warmer area in the colder months.
Structure yields an energy efficient, rigid, impact-resistant sheet that is significantly lighter in weight than solid polycarbonate, acrylic or glass sheets. SINHAI offers substantially better energy efficiency than any single-layer sheet.
