What type of insulation should I install under the floors of pier foundation house?
I have a 1932 pier and beam house in Austin, TX. The floors are very cold in the winter since there is no insulation underneath and many air vent holes in the side of the house to promote ventilation. I'm confused whether I should use open or closed cell insulation underneath the floors. I've heard that I could use open cell, open cell with a vapor paint barrier or closed cell. Does anyone know what the right answer is?
