Cold Frame

& High Tunnels

Cold Frames and High Tunnels include unheated greenhouse structures that help farmers and nursery owners extend their growing season by providing protection from the elements of nature. At Atlas, we manufacture many different sizes and strengths of high tunnels/cold frames for each geographic climate. The Basic High Tunnel Frame consists of a frame with a single layer of poly ﬁlm, roll-up sides, and doors and many additional options are available to include steel wall framing, steel base boards, automation for curtain systems, heaters, and gable vents.

The Budget Plus

Our most popular high tunnel structure, the 30 by 72-foot Budget Plus is NRCS approved and designed with a Gothic frame, offering strength and height to accommodate most growers. An excellent choice for a low-cost overwintering structure for the commercial nurseryman, the six-foot sidewall option available in this series provides eight-feet of clearance at two-foot in from the sidewall and offers greater ventilation when equipped with sidewall curtains. The peak height of 14-feet on the Budget Plus series allows ample space above the doors to accommodate gable louvers or fans for additional ventilation, if required.

The Emerald

Designed for the southern nurseryman, the Emerald, with its standard four-foot sidewall height, is the perfect structure for overwintering taller plant materials, shrubs or trees, and offers higher side walls and a lower peak height to maximize heating efficiency when supplemental heat is required. Because of its relatively flat roof profile, this structure is not recommended for areas with excessive ice and snow.
