Bubble Dome Dining Igloo - Mega 1 Inch PVC Hub + Strut + Cover Kits

There are substantial differences between the Sonostar Standard Bubble Dome and the Mega Bubble Dome. The Mega Bubble Dome uses Megahubs, larger and stronger than standard hubs, and requires thicker and stronger PVC for the struts. The advantage of the Mega Bubble Dome is that it can support a lot more weight from the frame than the standard dome. The covers for both domes are identical.  The Mega Bubble Dome is 11.75' in diameter at the base and stands 7' high in the center.  It will take about 1 1/2 hours to assemble the first time you do it.

The Hub Kit contains all the 4-star, 5-star, and 6-star megahub connectors needed to build a 3V 5/9 geodesic dome. All the hubs have 12 degrees of curvature built into each arm as well as molded holes to fit the bolts. Stainless steel nuts and bolts are included to connect the struts to the hubs. Inside the box, you’ll also find a soft rubber mallet to help you nudge any tight fitting connections together. A laminated assembly map and an instruction book make up the remainder of the kit. Megahubs are all white.

The Bubble Dome Strut Package consists of 176 furniture grade 1” Schedule 40 PVC struts (with UV additive). The struts are all color coded for 4 different lengths, which correspond to the colors on the assembly map in the hub kit. All the struts have been pre-drilled to fit the hubs. Struts can be either black or white.

Sonostar’s Bubble Dome Cover is made of durable 650 gsm PVC, ultrasonically welded, and is designed to specifically to fit the frame. It has a zippered front door, two triangular windows that can seal shut, and a canvas skirt that will make a ground level barrier to weather and animals.

The Sonostar Bubble Dome is designed to be an all-weather enclosure that can be easily assembled and disassembled. We recommend that you secure it to the ground once it is constructed. More important, the Sonostar frame is solid and long-lasting – built to be durable in any weather conditions and engineered for maximum strength.
