First apologies if this has been asked.  New member and couldn’t find a forum search tool.

Does anyone have any experience with the Owens Corning basement system.  I have a new home in New Hampshire and looking to finish the basement with a priority on air quality and energy efficiency.  I have heard these systems costs twice the price, but I like the idea of a drywall alternative and supposed speed of install.  I assume the walls are a EPS or XPS which is what I want anyway, but do they air seal all those seams.  Is it a quality system or am I better off with a traditional rigid foam and 2×4 stud wall.

Thanks

Charles
