Attics

Attack the Attic

What’s hiding in your attic could be very frightening. Not the critters or junk… but the potential for energy loss through an uninsulated or under-insulated attic.

Insulating and sealing the attic with high-quality solutions from Dow is one of the most cost-effective ways to minimize heat loss and gain through the roof. So less energy is required to heat or cool the home, reducing costs and greenhouse gas emissions.

Whether used as an unoccupied storage area or additional living space, a well-insulated and sealed attic helps:

  • Save money and energy
  • Increase comfort
  • Provide even temperature distribution throughout the home
  • Prevent condensation
  • Reduce mold, mildew, wood rot and odor
