These greenhouse autovents have been designed specifically to work with our unique full length ridge ventilation in our greenhouse range. They require no electricity to operate relying simply on the contraction and expansion of wax to open and close the greenhouse vents. The energy from the warmth of the sun and the surrounding air temperature causes the wax to expand which in turn opens the greenhouse vents. Similarly as the greenhouse cools the wax contracts and vents close. A very convenient greenhouse accessory that will ensure your greenhouse is well ventilated without your having to manually open and close the vents. The autovents are an extremely useful greenhouse accessory since they not only assist in keeping the greenhouse cool but also help to keep it well ventilated.
All our greenhouses have these fitted to the ridge vents as standard. The autovents will operate efficiently for a number of years but, like any moving part, will need replacing over the extensive life of the greenhouse. Such an important greenhouse accessory is held in stock and are simple to replace.
MK7 autovents are used as standard in the roof opening lights in our glasshouse range.
You may also choose to install autovents to the side windows of your greenhouse using the Bayliss triple sprung Mk7 autovent.
Measuring approximately 12 inches (30cm) in length the MK7 can lift a vent weighing up to six kilos. At full stretch on a hot day the autovent will give a maximum opening of approximately 12 inches ensuring good air flow around the greenhouse – especially if used in conjunction with our unique ridge ventilation.
We provide stainless steel fixings and a cedar block with the autovent to ensure that it is correctly mounted to a Gabriel Ash greenhouse.
Please give consideration as to the positioning of the autovent in relation to any greenhouse staging or greenhouse shelving. It is often best to place such autovents on the opposite side of the greenhouse to the staging or shelving in order to avoid complications.
