When it comes to insullation we first need to discuss the term "R-value".  

The R-value is a measure of thermal resistance used to describe the insulating properties of a material. It represents the ability of a material to resist heat flow, with a higher R-value indicating better insulation. 

Because of our multilayered approach to insullating the greenhouse, the R-value is determined by several things; 1.  The rate of heat transfer from the outside air to the surface of our first panel,  2. The rate of heat transfer through our first panel, and 3. The rate of heat transfer through the air pocket between the first and the next surface.  Because our greenhouse has 6 layers this process repeats itself for each layer.

Due to the high insulation value of air and the slow heat transfer between air and the surface of each layer, we are able to achieve an R-value 10 times higher than traditional greenhouses.
