Sainpoly pushes polycarbonate greenhouses for year-round crops in harsh climates

Sainpoly is promoting polycarbonate greenhouse systems for year-round controlled-environment agriculture in regions facing severe cold, hail, high winds, uneven daylight or large temperature swings. The systems use hollow polycarbonate panels designed to combine thermal insulation, impact resistance and light transmission, helping growers maintain more stable conditions for crops. Sainpoly says the technology can reduce winter heating energy use by two to three times compared with single-layer glass and limit weather-related damage, though the figures are company claims. The company says the approach is intended to improve crop yields and quality across a range of challenging climates.
