Hi all, first post and hoping for lots of great advice! When the master suite was added to our house, it was constructed with a flat roof. Later some misguided remodeler sprayed popcorn stuff on the (very low - 7') ceiling. Here is what I want to do: remove the dry wall (and existing pink batt insulation) thus getting rid of the popcorn, and then - in order to make the ceiling seem a little less oppressive - paint the rafters white, and install white "bead board" between each rafter. However I am concerned about insulation. What can I use between the roof deck and the new beadboard? Rigid insulation, cut into 16" strips? Is there anything I can use that will provide adequate insulation without filling up the entire 6" deep rafter space? If I fill it all up with insulation, it will defeat the purpose of removing the ceiling and trying for the "exposed rafter" look. Might as well just scrape off the popcorn and live with the low ceiling. Any suggestions? Thanks. BTW we live in San Antonio, where heat is a big issue but we do get some cold weather too.
