Another thing to do is put that silver stuff pointing towards the outside.
The stuff is around 40 dollars for a 4X8X2 sheet.

I have been thinking of ideas for insulating the greenhouse I have now, as well as building another one that is insulated. The most realistic idea I have is to make the north and end walls out of 1/4" OSB with 1/2" foil-faced foam panel inside that.

The panel is R2.7. I think R3 would be a realistic guess for the osb/panel combo.

The question that requires more creativity is, what if I wanted something retractable? Like a curtain or tarp that would roll up and down over the clear south wall, or possibly even insulated shutters that open and close. I can think off all sorts of crazy ideas, but I don't know the best one to pick.

This stuff is about the same price and has an r-value of 3.2 :

I like the insulated tarp idea. But I am wondering if I could make my own, to make a thicker version.
