Attic Insulation

Is your attic costing you money?

All it takes is a quick peek to find out. If your attic floor is insulated but the wood beams (joists) are still visible, you probably don't have enough. But even if you can't see your beams, that's still no guarantee that you have enough insulation. The best thing to do is measure.


For maximum energy efficiency, we recommend an insulation value of R-60 for attic floors - about 18 inches of insulation. Do you have enough? To find out your current R-value, and how much more insulation you need, use our Insulation Calculators.


Adding insulation to your attic is a blast with the AttiCat® Insulation Blowing Machine! It conditions the AttiCat® Expanding Blown-In PINK Fiberglas™ Insulation by breaking it up and fluffing it, adding millions of the tiny air pockets that give the material its insulating power. The insulation is conditioned further throughout the length of the hose, and as it bounces its way up to your attic, more and more air pockets are added, increasing its insulating power even more. And since Fiberglas™ insulation will not settle, it will keep its energy-saving R-value over time.


Quick and easy

  • Blowing the insulation should take less than 1.5 hours and the whole job can be completed in less than 4 hours based on a 1,000 sq. ft. attic at R-30

  • Owens Corning is committed to sustainable business practices, and we take pride in the fact that our energy-saving products make a significant net positive impact on the environment. In fact, in the first year of use, Owens Corning home insulation saves approximately nine times the amount of energy used by our company annually. And year after year, our insulation products continue to help conserve energy without consuming any additional resources.
  • By reducing the energy required to maintain a comfortable living or work environment, insulation reduces the greenhouse gas emissions released into the atmosphere through the burning of fossil fuels. Each year, Owens Corning insulation eliminates more than one billion tons of greenhouse gas emissions—equal to the annual emissions of 200 million passenger cars or two billion barrels of oil.
  • Eco-friendly manufacturing and distribution
  • Owens Corning PINK insulation not only saves energy; it also helps conserve natural resources by using widely available and plentiful resources—sand and recycled glass—in its manufacturing process.
  • All of our glass fiber and foam products made in North America are certified for their recycled content by Scientific Certification Systems (SCS). Our glass fiber products use an average of 40% recycled glass content, and our rigid foam insulation uses an average of 15% recycled content, with all foam scrap recycled back into the process instead of going to landfills. And when it comes to distribution, our compression packaging means we can ship more insulation per truckload, resulting in 25% fewer transportation miles and reduced pollution from truck emissions.
  • Green Approved by the National Association of Home Builders (NAHB)
  • Owens Corning is the first insulation and masonry veneer manufacturer to receive this approval, which will help builders and designers select products that meet specific green practices and can earn points towards the National Green Building Standard.
