Polycarbonate Brand Recommendations

Hello,

I am in the process of designing an in-ground greenhouse. I am planning to use polycarbonate sheets for the roof and endwalls, 4ftx8ft, and I am looking for recommendations for the best brands of polycarbonate and sources to purchase them from. I appreciate any information/tips one might have regarding this. The greenhouse will be in zone 4. Thanks!

Are you thinking about the polycarbonate with multiple walls or some other type?

Hi, thanks for your response. I would like to get twin-wall polycarbonate.

No problem, I know there are greater wall number varieties (like 5 wall) and I think some other flat sheet goods that are also made of polycarbonate.

I just used the kind they have in stock at Menards.  I don't know if it's good or bad so I wouldn't say I recommend it.  But at least if you have a Menards around, it gives you an option.
