Climate screens have become somewhat commonplace for floriculture and horticulture crops alike thanks to the role they play in promoting faster plant growth and development and improving plant quality, but they’ve proven to be especially useful in cold-climate regions.
“Thermal screens act like a winter coat, providing a barrier between the greenhouse covering and the plant canopy,” says Gretchen Schimelpfenig, energy engineer and executive director of Cornell University’s Greenhouse Lighting and Systems Engineering (GLASE) consortium. “Eighty per cent of greenhouse heating occurs at night, and thermal curtains provide an insulating barrier that reduces radiative heat loss.”
To determine which screen (or screens) is best for a greenhouse, Schimelpfenig says growers must consider several factors.
