Roof Window Opener
Roof Window Opener
Description
Keep your greenhouse perfectly ventilated with our range of roof window openers, available in manual and automatic options. Choose simple manual control or let the automatic models regulate airflow as temperatures rise. For larger windows, the heavy-duty storm-proof opener provides 70% more lifting power and a wide opening range for optimal growing conditions.
TECHNICAL SPECIFICATIONS
Compatible with all our aluminum and tempered glass greenhouses: The Retreat, The Cottage, The Residence, The Manor and The Estate
Three versions: manual, automatic, and automatic storm-proof
The automatic versions run on a sealed wax cylinder: no wiring, no batteries, nothing to plug in. They typically start opening around 68 to 77 degrees Fahrenheit and are fully open by roughly 86 degrees, which keeps the greenhouse from overheating while you are away
The storm-proof version holds the vent against sudden gusts on exposed sites

Everything you need to know before ordering
Answers to the most common questions about our glass greenhouse accessories.
Everything on this page is made for our aluminum and tempered glass range: The Retreat, The Cottage, The Residence, The Manor and The Estate. The parts use the same frame profiles, seals and fasteners as the original build, so nothing needs adapting. Accessories for the polycarbonate range are listed separately.
No. Common household tools are enough: a screwdriver, a wrench set and a cordless drill. Fixings are supplied and each item comes with its own instructions.
Manual roof vent windows, rain gutters and downpipes, the anchoring base kit, glazing seals, all fasteners and an illustrated assembly manual come with every glass greenhouse, not sold as add-ons. The items on this page are upgrades and additions, not missing parts.
Yes. Roof windows, openers, extra sliding doors, gutters and curtains can all be added at any time. Only the overall structure is fixed: the glass models cannot be lengthened after assembly, so the size is chosen at the outset.
Accessories ordered at the same time as a greenhouse travel on the same pallet whenever possible. Ordered on their own, they ship separately by parcel or freight depending on size. Shipping is free and fully insured to the 48 contiguous states either way, and tracking is included.
You have 30 days after delivery to request a return. Items must be unused, uninstalled and in their original packaging, with proof of purchase. Contact our team at support@primegreenhouses.com to start a return before sending anything back.
