Adding New Insulation Over Old Insulation

“Should I remove my old insulation, or can I put new insulation on top of the old insulation?” This is a question we at IBP Portland hear often. It is a valid question, and one worth considering as you seek to make your home as efficient as possible.

The bottom line is this: Yes, you can add insulation over old insulation. However, it’s not always the right choice. You may want to discuss your options with a professional insulation team before making a decision.

Can You Add New Insulation Over Old Insulation?

Can you put insulation over existing insulation? Yes, in most instances, you can. However, you must guard against mold and mildew growth. If the insulation appears wet, you have an underlying problem that needs to be addressed first. Wet insulation is a breeding ground for mold, mildew, or rot.

If the old insulation is dry and you decide to go this route, keep these tips from the experts over at ENERGY STAR in mind:

  • Don’t add faced insulation on top of your existing insulation, because the vapor retarder in between layers leads to trapped moisture.
  • Adding rolled, batt, or blown-in insulation over existing insulation is not a problem.
  • When adding, roll the insulation perpendicular to the joists, not parallel.
  • Do not tack down any rolled insulation. This smashes or flattens the insulating material and reduces its R-value.
  • Air seal the area before you add insulation, so it works well to keep your home energy-efficient.
