Technical Specifications
Dimensions
Typically, 27' wide by 41.5' long. You can have any length you prefer. You can use 42" hoop centers or up to 80" centers to optimize your steel and minimize costs.
Frame Material
All steel is 14 guage (2 mm wall thickness). Hoops are 1-7/8" (48 mm) exterior diameter. Square tubes and trussing use 1-9/16" (40 mm) exterior diameter. All steel is galvanized.
Glazing
Best in industry 6mm 4-layer polycarbonate panels (6.9' x 19') with an effective overall insulation value of R-2.2. It is impact resistant with a 1-2 mm diameter hail (based on velocity) rating.
Trim
We provide all the trim for construction including J-channel trim around open channels in your vents and doors, butt joints for your panels, ridge trim and end wall flashing.
Hardware
The kits come with all fasteners and brackets to assemble your greenhouse including self drilling screws and different kinds of connectors.
Building Permits
Typically, laws allow jurisdictions to provide you with agricultural related building permits that do not require adherence to structural building codes.
Warranty
The polycarbonate has a 10 year warranty against cracking and SIGNIFICANT yellowing. The steel is likewise warranteed against defects for 10 years.
Construction
Working with steel is challenging. Building these greenhouses requires experience. We provide construction services for all or part based on your needs.

The CatchSunlight Difference
The Federal Government offers greenhouse grants through the USDA and NRCS. In many cases, the high-tunnel greenhouses provided to grant recipients are constructed with polyethylene film coverings. Due to their lightweight construction, these greenhouses exceed a two-year lifespan only about 50% of the time.
Regardless of whether a grant is obtained, our greenhouse kits are engineered with heavier-duty frames and feature polycarbonate panels that withstand extreme wind conditions and do not tear like polyethylene. These structures are designed for long-term durability and are likely to last a lifetime. When factoring in the additional costs of end walls and sidewall materials, our kits are typically comparable in price to polyethylene greenhouses.
Catchsunlight greenhouse kits are delivered complete, providing all necessary components to construct a high-quality, long-lasting greenhouse.
We don't cut corners. Every component is selected for longevity and performance in harsh climates. When you choose CatchSunlight, you're choosing a greenhouse that will outlast and outperform the competition.
