The recent practice of raising multibitable buildings without heated heating implies the design of a high-density plastic sheet gutter, usually 300 microns, widths up to 1 m. Unlike tin cans, these plastic transparent gutters can be easily dismantled or, in some cases, sacrificed in the winter to prevent falling and crushing of structures. High transparency in the early-spring and late-autumn period is of great importance for early harvesting and the prolongation of the reading season, and for years, the greenhouse is less heated, and it cools easily during the night.
