The Energy Star site is your safest bet for information on how to get the credit. Energy Star has been pretty flexible on what it allows for this credit:

  • Batts
  • Rolls
  • Blow-in fibers
  • Rigid boards
  • Expanding spray
  • Pour-in-place 

Products that reduce air leaks also qualify:

  • Weather stripping (such as fabric, foam, or metal to provide a seal)
  • Spray foam in a can, designed to air seal
  • Caulk designed to air seal
  • House wrap

Installation isn’t covered.

Don’t rely solely on contractors who may not know the details or who promise their products will get the credit in order to make a sale.
