In each case, a compromise is needed.

Materials for frame greenhouses can be both steel and plastic, or wood. Metal frames are certainly reliable, but the high thermal conductivity of the metal makes you take care of the additional thermal insulation of this design. The transparent “dome” is made from the “double -glazed window” at the basis of which lies both simple thick glass and modern plastics. In the case of natural glass, it is necessary to calculate the strength of the structure, t. To. its weight does not allow the use of lightweight options. Organ -glass and polycarbonate are more democratic in weight and less fragile, but they are less transparent, which means they miss less light, which is not suitable for all plants. In each case, a compromise is needed.
