floor insulation
 |
Insulating any floors above your unheated garage will help reduce the energy costs for the above conditioned space.
Insulation techniques
When insulating floors over unconditioned garages, use the following techniques:
- Seal the joint between the header or band joist and the subfloor
- Seal the joint between the top or sill plate and the header joist
- Seal all air leakage sites in the floor (e.g., electrical penetrations)
- Trim insulation to fit snugly with no gaps
- Staple the kraft paper to the floor joist from above instead of using wire mesh or stay wires to hold the insulation in place
- Install an air barrier to prevent cold air in the garage from "short circuiting" the insulation underneath the subfloor
