Canopia by Palram Automatic Roof Vent Opener was designed to automatically control the temperature in all Canopia by Palram Greenhouses. As the air inside the greenhouse warms, the vent gradually opens to allow the correct amount of airflow into the greenhouse and closes when the optimal temperature is reached. The Canopia by Palram vent arm was designed with the use of natural wax that expand to push a piston, which raises the window, as the air gets warmer than contracts as it cools, closing with the use of a spring. This automatic vent opener operates without the use of electricity.Note: This product may require up to 2 additional days for order processing prior to shipping

For additional information on this product, please see the Product Documents section for all downloadable user manuals, installation guides, brochures and warranty statements.

  • Opens roof vent window automatically around 68F for air circulation, closes when temperature cools
  • "Smart-Lock connectors make installation quick and easy "
  • Palram vent arm was designed with the use of natural wax that expand to push a piston, which raises the window, as the air gets warmer then contracts as it cools, closing with the use of a spring

Must have item for your greenhouse

a year ago
We havr a manual window in our greenhouse and this window automatically opens and closes with the temperature. Our plants don’t burn any more. It takes the guesswork out of opening and controlling the window.
