Lisa Chen
Versatile Transparent Sheets for Greenhouse Windows

"My greenhouse in the UK relies on transparent polycarbonate sheets for maximum light intake. The 4mm hollow sheets provide excellent insulation while maintaining high clarity, boosting plant growth. The anti-fogging treatment prevents water droplets, and the UV-stabilized surface has remained clear after 4 years of use. Highly recommend for serious gardeners."

Ravi Patel
Khalid Al-Khalifa

"A factory in India used transparent polycarbonate sheets for machine room windows. The 6mm solid sheets withstand industrial vibrations and provide clear visibility for operators. The chemical-resistant coating is easy to clean, and the UV protection prevents yellowing from factory lights. A reliable choice for industrial environments."
