Polycarbonate Greenhouses
A polycarbonate greenhouse uses multiwall or twin-wall PC panels on a framed house to balance light transmission, insulation and impact resistance for commercial and protected cropping. It is a common alternative to glass when a lighter rigid cover is preferred. ClimaSpan supplies the climate equipment—exhaust fans, cooling pads and circulation fans—not the polycarbonate structure. Panel type and structure layout are confirmed on the quotation after inquiry to [email protected].
Structure features
- Multiwall or twin-wall polycarbonate panels on a metal frame (single-span or multi-span).
- Better thermal insulation than single glass in many layouts, with lower panel weight.
- End walls and sidewalls can include openings for exhaust fans and evaporative pad systems.
- Suitable for commercial vegetables, flowers and nursery work where a rigid plastic cover is preferred.
Suitable climate
- Used in cool to hot climates when ventilation and cooling are sized to local peaks.
- In hot regions, pad-and-fan or strong exhaust ventilation is often evaluated alongside shading.
- In cooler seasons, the insulating cover can reduce heat loss; heating design stays with your energy plan.
- Tell us location and house size so fan and pad selection follows the real climate load.
Covering materials
- Twin-wall or multiwall polycarbonate sheets as specified by the structure supplier.
- UV-protected outer faces and sealed edges as designed for the frame.
- Roof and wall panels with fasteners and flashings per the structure drawing.
- Panel thickness and light-diffusion grade are project choices — not listed as ClimaSpan catalogue numbers here.
Selection notes
ClimaSpan supplies greenhouse climate equipment (exhaust fans, evaporative cooling pads and circulation fans). Frame and covering details for your structure are confirmed with your project team. We do not publish a public price list or catalogue-spec sheet on this page.
- Share length, width, height, span count and location.
- Note crop type, summer cooling goals and any existing openings for fans or pads.
- We recommend climate equipment and quote by project.
Companion climate systems
Exhaust Fans
Wall-mounted fans that remove warm, humid air and create negative pressure for pad-and-fan or vent layouts.
Cooling Pads
Evaporative pads that cool incoming air when paired with exhaust fans.
Circulation Fans
Fans that move air inside the house so temperature and humidity stay more even.
Other greenhouse structures
Glass Greenhouses
Rigid glass-clad commercial and research houses.
Film Greenhouses
Plastic-film single-span and multi-span houses.
High Tunnels
Single-span film tunnels for protected cropping.
Frequently asked questions
Glass vs polycarbonate greenhouse — which covering fits better?
Glass offers durable clarity; polycarbonate is lighter and often more insulating in multiwall form. Choice depends on budget, structure design and local practice. ClimaSpan helps with the climate equipment once the covering is chosen.
Does ClimaSpan supply polycarbonate panels or frames?
No. This page is a structure-type guide. ClimaSpan quotes exhaust fans, cooling pads and circulation fans for houses that already use or plan polycarbonate covering.
Can pad-and-fan cooling work on a polycarbonate house?
Yes, when end or side openings are designed for fans and a pad wall. Send drawings or clear dimensions so airflow paths can be reviewed with your quote.
