Jan van der Meer

High-Yield Polycarbonate Greenhouses for Commercial Agriculture

"Our greenhouse in the Netherlands uses Sinhai’s hollow polycarbonate sheets, and crop yields have increased by 25% due to optimal light and temperature control. The double-wall structure provides excellent insulation, reducing heating costs in winter. The UV-blocking layer protects plants from harmful rays, while the anti-fogging coating prevents condensation. A reliable choice for large-scale farming."

"A community garden in Toronto opted for Sinhai’s polycarbonate greenhouse panels for their affordability and ease of use. The lightweight sheets made it easy for volunteers to assemble the structure, and the transparent finish provides ample light for year-round gardening. The 10-year warranty gives us confidence in their longevity, even through harsh Canadian winters."
