I am in the process of bidding on a new construction and we are talking about whether we should be using foam insulation. I have heard some people say it makes the home almost too tight and doesn't allow it to breath. what are peoples' thoughts on foam vs. more traditional forms? Is it better to use foam in certain places in the home, like windows and doors and use traditional insulation in the walls? I am being told it can cost upwards of $35,000. We are in the northeast and Rye is not an area affected by the housing market. Any feedback would be greatly appreciated.
