Some companies integrate polystyrene beads into concrete blocks, while others make concrete blocks that accommodate rigid foam inserts.
Air and Vapor Barrier in a single: Closed-cell spray foam insulation makes an air and vapor barrier in a single. Homeowners concerned about humidity or vapor will not likely have to put in a vapor barrier about the dried foam.
Radiant barriers are more effective in very hot climates, especially when cooling air ducts can be found within the attic. Some research demonstrate that radiant boundaries can lessen cooling fees 5% to 10% when Utilized in a heat, sunny local climate.
