My husband asked me yesterday how much triplewall poly costs when you purchase it alone, and I did not know.

I am going to do the usual internet search for prices, but wanted to find out if anyone here has built a gh w/ triplewall. It's not as flexible as other poly I imagine, since BC indicates the front and back walls are a single sheet of material.

How one would attach the poly to the wood frame I don't know, but there must be a way w/o jabbing holes in it.

One reason he is wanting to explore building it ourselves is that he's a designer, and our backyard is a strange shape.

A 12x16 ready-made would just work due to 1/2 the yard being table-rock 3-8 inches below the surface. We paced off an area 12x16 where we know no rock exists, but this places the gh in an odd position, and would probably still have one piece of table rock in the front corner of the gh about the level of the foundation.

thanks for any advice you can give.
