ThermaGro Greenhouses are manufactured from the highest quality components. Durability and efficiency are achieved by glazing the greenhouse with a superior 8mm twin-wall polycarbonate sheeting, which is 60% more efficient and 200 times stronger than single pane glass. A superior product, the sheeting is warranted against chipping, cracking, fading, peeling, excessive yellowing, and hail penetration for ten years. Curved "gothic arch" and conventional straight-wall styles are both available in a kit form and in 10 sizes from 8'x8' to 12'x20'. All kits come complete with a steel anchoring base and a complete electrified ventilation system. Additional options and custom designs are available. Call us for more details.

Unique Gasketing System for a Hermetically Sealed Structure
Self-Drilling Fasteners for Ease and Durability
We believe that the greenhouse must be anchored on a flush level and square base. Thus, each kit includes a coated, 2" x 4", hollow steel base that is anchored to the ground via caissons (8" diameter tubes) on each corner. The base of the greenhouse is then screwed onto the 2"x4" steel base.

All greenhouses are available in a conventional straight-wall or a curved "gothic arch" style. Both styles are complete in a kit form or can be installed by our qualified installers. Our only requirement is a level area on which to anchor and assemble the greenhouse.
