Replacement opening vent, or simply opening window kit, suitable for Halls 8ft wide greenhouse range.
If you want to add an additional opening roof vent for your 8ft wide Halls greenhouse this kit is all you need. It replaces an existing piece of 600mm x 600mm (24ins x 24ins) glass in the roof. If you have long pane toughened glass in the roof you will have to buy a shorter piece of toughened glass for the section below the new vent.
Adding an additional vent improves the flow of air through the greenhouse which is paramount in the summer months to stop rot and fungus on your precious crops.
How to Fit a Replacement Roof Vent
Fitting them is straight forward. In essence you have to remove a panel of the existing glass (600mm x 600mm) and slide in the opening roof vent when you have screwed it together. The removed glass is then transferred into the new opening vent. Comprehensive installation instructions are supplied with the unit. Note: the opening vent is not supplied with glass.
