Opening Triangle Glass Windows
Upgrade your dome with two opening, double-pane triangle glass windows
for brighter views, better airflow, and a more premium guest experience—without sacrificing weather protection.
Why this upgrade is worth it
Ventilation where you want it — create a natural breeze and reduce condensation.
Clearer views — glass gives a cleaner, more “architectural” finish than fabric vents.
Guest comfort — helps regulate heat in summer and improve airflow year-round.
Secure + stable — includes a locking latch and a hydraulic arm to hold the window open at your preferred angle.
Add-on: custom velcro mosquito screens included!
*2 opening glass triangle windows are included in our Deluxe Glamping package - 3 for 9m and 10m domes!
Availability note: Currently sold in 2-packs for safe shipping. Single windows may be available only when ordered with a custom dome and packed at the factory.
What’s Included
This kit is designed to make installation clean and secure.
Opening triangle window with hydraulic arm
Thick triangle mounting bracket
3× attachment bars (specific to your dome size)
Thin metal finishing strips
Self-tapping metal screws
Dimensions (for standard kits)
Outer perimeter: 43 × 42 × 43 in
Inner perimeter: 35 × 34 × 35 in
Fit note: Our in-stock triangle glass windows are one standardized size. Depending on your dome size and triangle layout, they may not fully cover an existing fabric vent opening—many customers choose to install them in a new location for the cleanest finish.
Electric Opening Triangle Window
(New Upgrade Option)
Want the same premium look with push-button operation? We offer a motorized (electric) opening option for triangle glass windows as a custom upgrade.
Benefits:
Effortless ventilation (ideal for higher placements)
Great for rentals where guests want simple, intuitive control
Clean, modern feel that pairs well with premium interior finishes
Custom order note: Electric opener configuration, size, and lead times vary by project—reach out and we’ll recommend the best setup for your dome.
Opening Window in Panorama Area (Custom Order)
For customers with a Glass Panorama window section, we can offer a custom opening window integrated into the panorama area (by request).
Why customers choose it:
Ventilation + view in the same feature
Keeps the “wow factor” of the panorama while improving airflow
Ideal for Residential Domes with Multiple Rooms where fresh air matters
Custom order only: This option depends on your panorama configuration and dome model—contact us to confirm feasibility and pricing.
Opening Triangle Window in the Skylight (Custom Order)
If you want ventilation from the highest point of your dome, we can provide a custom opening triangle window integrated into the skylight area. This is a popular option for improving airflow and helping hot air escape naturally.
Why it’s a great upgrade:
Releases heat fast (hot air rises—this lets it out where it gathers)
Helps reduce condensation by improving air exchange
Better comfort in summer without relying only on fans
Premium finish while keeping the skylight zone functional
Custom order note: Skylight-opening windows depend on your dome model, skylight configuration, and triangle orientation. We’ll confirm feasibility, placement, and hardware options during quoting.
