Typically, the thickness of the outer layer is about 0.6 cm, and the inner layer is about 0.4 cm.
It should be known that the thicker the sheets ivory coast mobile database cellular polycarbonate, the lower the thermal conductivity will be, which means there will be less heat loss if the ends are insulated from the entry of cold air.
In the case of arched greenhouses, however, you should not lay too thick sheets of polycarbonate, it can simply break or the bending force will be critical and it will break significantly before its service life expires.
Of course, the price also plays a role, thick sheets of polycarbonate, say thicker than 1.5 cm, cost quite a lot of money. So it is not worth taking risks and overpaying - 1 cm, no more.
