Film Greenhouses
A film greenhouse is a framed growing structure covered with agricultural plastic film, used for commercial horticulture in single-span and multi-span layouts when a lighter, replaceable covering is preferred. Climate control still depends on planned airflow through vents, exhaust fans and optional pad walls. ClimaSpan supplies the climate equipment—exhaust fans, cooling pads and circulation fans—not the film or frame. Structure type is confirmed on the quotation after you contact [email protected].
Structure features
- Flexible plastic film over arches or a multi-span metal frame.
- Lower first covering cost and easier film replacement cycles than glass in many markets.
- Roll-up sides, gable vents or dedicated fan openings are common for air exchange.
- Used for vegetables, berries, flowers and nursery stock in single-span and multi-span layouts.
Suitable climate
- Common in temperate to hot growing regions where seasonal or year-round film houses are standard.
- Hot climates often need strong exhaust ventilation and may add evaporative pads on the inlet end.
- Windy or storm-prone sites need film and frame detailing from the structure supplier; ClimaSpan sizes climate equipment after openings are known.
- Share location, house type and peak temperatures so equipment matches the film-house load.
Covering materials
- Agricultural polyethylene or co-extruded greenhouse films as specified by the film supplier.
- Single-layer or double-layer inflated film systems depending on the structure design.
- Film fasteners, wires and gutters per the frame manufacturer.
- Film thickness, UV life and light-diffusion grade are supplier choices — not ClimaSpan catalogue specs on this page.
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 We do not publish a public price list or catalogue-spec sheet on this page.
- Send span type, length, width, height and location.
- Describe side vents, existing fans and whether a pad wall is planned.
- We propose 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.
Polycarbonate Greenhouses
PC-panel houses balancing light and insulation.
High Tunnels
Single-span film tunnels for protected cropping.
Frequently asked questions
What is a film greenhouse?
It is a greenhouse whose main covering is plastic film rather than glass or polycarbonate panels. Frames may be single-span or multi-span.
Can ClimaSpan equip a multi-span film house?
Yes. We quote exhaust fans, cooling pads and circulation fans for film structures when you provide dimensions, openings and location.
Film vs high tunnel — what is the difference?
High tunnels are usually simpler, often unheated single-span film structures. Film greenhouses here include commercial multi-span film houses with planned climate systems. See also our high-tunnel page.
