Hi Mark,
I built a couple of buildings with Polycore when you first started.
I just started exploring an above ground greenhouse for an acreage. I need a well insulated floor and a way to tie the building to the ground if the floor is not concrete. North half the building and roof will be insulated as well as 4 feet on the south side. Raised growing beds. Some way to use water for thermal mass if the floor is not concrete. Are you interested In discussing this. Affordability is a concern.

Don; good to hear from you. Yes we can certainly discuss, we should be able to come up with a couple options. I will send you a direct email with my contact info and you can call anytime. Thanks!

I have an earth floor under my cottage. Local regulations do not allow for us to pour concrete.
I have levelled it and was going to have the spray foam guys come and seal the floor with me putting strapping over the foam afterward to lay a subfloor. Your system looks nicer and easier. By floor space is 28 ft by 16ft. 450 sq feet.. I live in Quebec. Is your product available here? 450 577 0673.
