We are pleased to announce the new polycarbonate has an improved insulation value from R 2.5 to R 3.03. The light transmission decreases from 72% to 62%, but this has not been a problem. There is no extra charge for this upgrade

New Wall Plate Options

We have recently made a change to our lumber kit policy. Due to our recent experience with moving domes to new locations, we have noticed the pressure treated lumber bottom plates last significantly longer than those without. The reason we have not always used them is because of our customer’s concerns about chemically treated wood. However, the treated lumber is covered with sheet metal and the other side with the T1-11. The dome then sits on washed gravel which drains the moisture away, and the treated portion is not in contact with the soil.

We have also noticed that more and more building departments are making this a definite requirement. This lumber is also termite resistant. We would like to notify all our customers that we are making the pressure treated bottom plate a standard addition to all our domes at no extra cost.

For those who do not want this addition there is a more expensive alternative in the form of redwood or recycled plastic lumber and we will be happy to discuss this option. Also for folks in termite prone areas we have a fiber cement siding option to replace the T1-11 siding.

Metal Glazing Trim Kits

This improvement is for new domes & ones in need of maintainance. The aircraft tape has seved us well over the years, with a life of 5 to 10 years, but custom designed aluminum strips over a sealing tape will last even longer. Enquire for upgrade price for new domes and maintenance kits.

Solar Fans

For the 26 ft dome and solar fan upgrades, we are supplying a new type of solar powered cooling fan. The fan is a little smaller, but is much more energy efficient and produces the same airflow as our previous fans. It has many more blades and even works in cloudy conditions. There is no extra charge for this new fan above the upgrade price.
