Cost-efficient polycarbonate greenhouse coverings are available in many sizes. This material resists hail damage and allows good light transmission. It also has a small air channel that provides some insulation.

Polyethylene film is the least expensive greenhouse covering and may be installed in a single or double layer. If you use a double layer, you'll need to blow air blown into it. This material provides good insulation, but the poorest light transmission of all greenhouse coverings. It needs to be replaced every few years.
