Answer: A
Glazing material in polyhouse construction refers to the covering material: the transparent or translucent sheet, such as polyethylene film, polycarbonate or glass, that covers the frame and lets light in while holding the heat.
It is not the growing medium, irrigation material or the matting used on the floor.
The glazing keeps out rain, lets in light and holds the warmth. Ultraviolet stabilised polyethylene film is the most common glazing in India, because it costs less than glass or polycarbonate.
