I am almost through framing my deck at home in Seattle, WA and I’ve been planning on using 1×6 Ipe. I could finish the whole thing without seams with 16′ boards. I’m wondering if anyone has had practical experience with installing boards this length/dimension? I’ve read comments regarding concern about cupping in a 1×6. I’m not sure whether to take them seriously when there are just as many comments regarding the stability of the wood. Is it worth spending the money for a 5/4×6 or should I go with a 1×4? Also, is the 16′ length going to be a bear to work with for a 1×6 regarding any straightening that needs to be done?
Thanks for any advice,
