THERMOFOR AUTOMATIC GREENHOUSE ROOF WINDOW OPENER (AUTOVENT)


Please note: The best offer button will automatically decline offers as we have now lowered the price to the lowest price we can sell for. (eBay will not let us remove the button)


Automatically opens and closes your greenhouse window as the temperature changes.

Complete kit, ready to install with easy to follow instructions. Fits most greenhouses.

If you have one of the "trapped polycarbonate" type of greenhouse which are currently being sold on the internet there is nothing for the clamps to fit onto and these units will not be suitable for you.

This opener is the latest in a line of THERMOFOR® roof vent openers designed and supplied over the past 50 years.  This model is an attractive cost effective unit with a unique opening action, ensuring a smooth twist free operation, and with the cylinder mounted within the bracket to eliminate projection in the greenhouse.  It is finished in a durable polyester powder coating and is corrosion resistant throughout.  Easily fitted to Aluminium and wooden greenhouses it will lift up to 7kg (15.45 lbs), i.e a vent weighing up to 14kg (glass area not exceeding 0.75m² in an aluminium frame), with a maximum opening of 35cm (14 inches).

Manufactured in the UK by a company with 50 years experience of these vents - please do not compare with cheap far east copies.

We also stock other autovent  models from Thermofor - the side louvre opener and a heavy duty double spring roof vent model for use in exposed locations, with polycarbonate glazing or for side windows, spare cylinders for these are available in our ebay shop. We also supply Bayliss XL, Standard Mk. 7, Triple Spring Mk. 7 and Mk. 7 HYDRAULICHECK vent openers as well as spare cylinders for all the autovents we sell.

If you're looking for an opener for conservatory windows or very large greenhouse vents we stock the Bayliss Mk. 7 Super and the GIGAVENT which are designed for very heavy windows.
