Pictured above is a Solargon 30 project with walls and the crown beam assembly up and ready for roof panels. Attached to this is an addition which will serve as an entrance and bathroom. Assembly time was two and a half days for the walls and roof panels. "What a great way to build!", was the comment from the builder referring to the cam lock SIPs panel system. " You don't need a lot of skilled labor to put one of these Solargons up. You just set the panels up on mounted base plates and slide them together and the camlocks do the rest. "
