Material: As the name suggests, a glass greenhouse is made of glass panels, while a film greenhouse is made of plastic film.
Insulation: Glass greenhouses are more insulated than film greenhouses. The glass panels are thicker and provide better insulation against the cold, wind, and rain. The plastic film used in film greenhouses is thinner and less insulating so it may require more heating in cold weather.
Cost: Film greenhouses are less expensive than glass greenhouses. Glass is more costly than plastic film, and the installation of glass panels requires more labor, so glass greenhouses are generally more expensive.
Light transmission: Glass allows more light to enter the greenhouse than plastic film. This can be an advantage in areas with low sunlight or in winter when sunlight is limited.
Durability: Glass greenhouses are more durable than film greenhouses. Glass panels are less likely to be damaged by hail, strong winds, or other environmental factors. Plastic film can be torn or punctured, which can lead to damage to the greenhouse structure or plants.
Maintenance: Glass greenhouses require more maintenance than film greenhouses. Glass panels should be cleaned regularly to ensure maximum light transmission, and they can become cloudy over time, reducing their effectiveness. Plastic film is easier to clean and maintain.
