The HF web site has all the information on pricing. They pack them adequately for shipping. Our door panels are backordered, everything else shipped right away and arrived safely by FedEx. Expect to spend $500.00 or more if you are replacing the entire polycarb.

I've been thinking of purchasing a 6x8 when it goes on deep sale just to have the replacement panels for my 6 year old hfgh. I will check out the website for replacement panels as well.

I misread the original post. I expect it will be less than $500.00 for an 8x6. That's about as specific as I can be. By the time our doors arrive, we expect to have spent $500 or more for replacing every panel on a 10x12 including shipping.

Or, you could pay more for higher quality twinwall panels from a greenhouse supplier and have them last longer.

Here is a link to a simple calculation done comparing HFGH prices at the time to another source of polycarbonate panels.
