Roof Vents D-I-Y
Natural Ventilation with Roof Vents
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 w wire and base for vents to be installed on a polycarbonate greenhouse. Please let us know in the comments of your shopping cart if this is going in a polyfilm (w wire and base included) or polycarbonate greenhouse (no w wire, no base). These vents are 36.5″ x 20.5″ x 4″ with an interior opening of 30.5″ x 12″. This is a great addition to a homemade greenhouse or certain greenhouse kits.
