I'm replacing my deck and adding additional space for a fairly large deck. I'm trying to determine what material would work best. I live in Georgia, so summers can get really hot and humid. Half of the deck will be in full sun and the other half fairly shaded. While composite decking seems to be fairly maintenance free I worry about the heat it would absorb on the sunny side of the deck(I'm usually barefooted most of the time in the summer). PT lumber would be the most economical, as I am doubling the size of the deck, versus using cedar or redwood ($$$) but I just did extensive remodeling and I don't want it to look like I did the deck on the cheap. Suggestions?
