Greenhouse Roof Window

Roof vents are a valuable accessory to your greenhouse. They will allow the hot air in your greenhouse to be ventilated naturally without any electricity. These roof vents come with a solar powered automatic opener that can be set to open between 65 to 75 degrees F. Warm air will rise and exit through these openings. These are constructed of aluminum and a UV protected polycarbonate. They only weigh 8.5 pounds and are easily installed. They can be installed directly into the film coverings of polyfilm greenhouses using the pre-installed base channel and a wiggle wire (included). If you are installing on a polycarbonate greenhouse you will need to build a curb to install these. We do not include the wire and base for vents to be installed on a polycarbonate greenhouse. These vents are great addition to a homemade greenhouse or certain greenhouse kits.

●【OPTIMAL VENTILATION】Your plants are optimally ventilated through temperature-controlled opening and closing. Depending on the temperature, the piston of the cylinder moves and opens or closes the window.
●【NO ELECTRICITY REQUIRED】Environmental awareness preprogrammed - the automatic window opener is a temperature-controlled, fully automatic device.
●【ULTRALIGHT】 Easy to transport thanks to the ultra-light and practical construction and perfect for all windows of common garden and greenhouses made of aluminum.
●【INDIVIDUALLY ADAPTABLE】Can be installed quickly and easily for the windows of common garden and greenhouses. You can steplessly adjust the opening angle by turning the cylinder and thus achieve the right ventilation for your bed.
