I just built a 15" tall riser for my basement HT room that is about 7' deep by 9' wide. The floor underneath the riser is concrete. The following are my questions:
- Do I need to insulate the entire cavity? Or just the majority of the cavity?
- Should I put a plastic sheet down over the concrete floor before installing the insulation?
- What type of insulation should I use (ie F/G batts, loose fill, cellulose, etc).
- Anything else I should be aware of prior to insulating?
