Polycarbonate Sheets - The Material for Greenhouses

29 Mai 2013

Greenhouses, unlike other structures, have an ultra-light design and do not use costly, complex substructures. Lightweight, rugged and transparent polycarbonate is ideal for greenhouses coverings. It allows maximum daylight into the greenhouse which increases its fecundity per square meter.

Most of the professional polycarbonate sheet producers of greenhouses are located in Europe. Corrugated and low thickness multi-wall polycarbonate sheets are the most suitable for greenhouses covering.

Corrugated polycarbonate sheets provide approx. 90% light transmission but no thermal insulation (U-Value), while multi-wall sheets provide approx. 80% light transmission with good thermal insulation.

Once we are familiar with the differences, what would be the ideal combination of the two types of sheets in a greenhouse structure? The answer is: corrugated sheets for the roof and multi-wall sheets for the walls.

Corrugated sheets installed on the roof maximize the natural daylight in the greenhouse. The lack of thermal insulation becomes an advantage – the heat loss through the roof prevents snow from accumulating during winter time.

The advantages of the greenhouse walls made out of the multiwall polycarbonate sheets are firstly, the high light transmission to the interior of the greenhouse (depending on the sun direction) and secondly, good thermal insulation that allows for reduction of the heating costs in the winter.

Polycarbonate sheets, with their excellent light transmission and the resistance to impact, are definitely the best choice for a greenhouse. They are an excellent replacement for broken glass roofs and walls without the need of changing the substructure.
