Re: Canexcel Siding
I purchased about 2500 sq ft a few years back to do my house. Like Marks experience, it was crowned. By the time I got to the 3rd row on a 28' wall, I had a 1" gap in the siding. After complaining to HD, they had a rep come out and look at it. At first, he tried to convince me to cut the siding into shorter pieces (6'!) to get around the crowning. I explained that it would look like crap and cost a fortune in caulking and that I wasn't interested. He then offered to replace the damaged bundles, and I told them to take all the bundles back as I wasn't interested in testing every piece and waiting weeks for replacement pieces. They finally gave in and credited my money back.
Still like the look of the product compared to vinyl siding. You may also want to consider the Hardy cement board that looks pretty much the same.
Also, google for information on mould problems that they had decades ago. I think the problem has been resolved now.
