Optional Comfort: Automatic Window Opener

This opener uses thermal activationโno electricity needed!โto sense temperature changes inside your greenhouse. It automatically sets the windows to open or close depending on the weather, ensuring perfect ventilation even when youโre away. Let the opener do the worrying for you.
Optional Security: Wind Restraint System
If your property deals with heavy, unexpected gusts of wind, we highly recommend adding the optional Wind Restraint System. This system is engineered to secure your roof window, allowing you to control the exact degree to which it opens. It is designed to withstand strong wind forces and protect your valuable greenhouse from sudden gusts and accidental damage, ensuring your investment stays safe and sound.
Manufacturerโs Note on Installation
Please be aware that this additional roof window kit provides only the structural aluminum framing, hinges, and hardware. To complete the installation, you will need to cut one large existing polycarbonate panel already supplied with your greenhouse. A portion of this panel will be used to create the new vent piece, and the remainder will be used to fill in the space where the vent is installed.
