Panel Options

This dome can be purchased as a bare frame or with an optional panel mounting kit to create a fully enclosed structure.

Additional contents with panel kit:

• 50 glass holding bracket assemblies used to secure panels to the structure
• 26 meters platinum cured silicone weatherstripping to support and seal panels

Panels are held tightly on the round tubes using glass holding brackets. These brackets clamp the tubes and push downward onto the panels from the exterior. The panels rest on high-quality platinum cured silicone gaskets shaped to support the panels, resist UV exposure, and withstand temperature extremes.

Material Choices

25mm Insulated Polycarbonate
This option provides the highest insulation value of R4 using four-layer honeycomb multi-layer greenhouse polycarbonate panels. The kit comes with 11 pentagon panels to clad the entire structure. The bottom five panels have pre-cut openings for the feet. An entrance can be cut in your desired shape using a saw or hot melting plastic cutting knife. These panels have 75% light transmission and are translucent, but not see-through.

8mm Clear Polycarbonate
Select this option if a clear view from the outside or inside is part of your vision. Clear polycarbonate has a lower insulation value than the insulated option. It heats up faster during the day and loses heat quicker at night. The kit comes with 11 pentagon panels to clad the entire structure. The bottom five panels have pre-cut openings for the feet. An entrance can be cut in your desired shape using a saw or hot melting plastic cutting knife. These panels have 90% light transmission and are translucent, but not see-through.

9mm Low-E Glass
For the most premium option, annealed safety glass with an infrared reflecting coating offers strong scratch resistance and mechanical strength. It is notably heavier than the polycarbonate options. The glass kit comes with 10 panels. One of the five lower pentagons is skipped for the opening.

Before You Buy

Before ordering, review your available space carefully. The dome has a 7.5 ft diameter footprint on the ground and reaches 10.5 ft high from floor to ceiling.

Choose a level location with proper drainage and enough access for delivery, assembly, and long-term use. Since anchor bolts are not included, plan your mounting method before installation.

If you choose a panel kit, consider how you plan to use the dome before selecting your panel material. Insulated polycarbonate offers the most warmth. Clear polycarbonate is better for visibility. Low-E glass offers a premium finish, scratch resistance, and added mechanical strength.

It is also smart to check local codes, HOA rules, zoning limits, and permit requirements before installation. Customizations may be available at an additional charge.
