Polar Series

Economical, year-round cold frame protection

The Polar Series cold-frame greenhouses provide economical protection for crops, allowing you to efficiently over-winter at a lower cost than a multi-purpose greenhouse. The Polar and Polar Cub are designed for easy construction, with bows that slip over their in-ground columns, and a bracket ridge connector to simplify purlin placement. The Polar’s gothic roof profiles are designed to easily shed rain and snow, all year-round.

Use it as a shade structure or summer storage during the off-season. Convert it into an over-wintering structure by removing the shade cloth.
