Benefits of Attic Insulation

Ensuring your attic has the right amount and type of insulation can provide many benefits. Insulation will: 

  • Stop your HVAC system from overworking and extend its life span
  • Improve your HVAC evenness and heating efficiency
  • Add to your energy efficiency
  • Improve your air quality
  • Form a noise barrier 
  • Prevent pest infestations

Best Insulation for Attics

Every insulation material has its own unique benefits and disadvantages, so we offer a wide range of options for every priority and budget. They include: 

  • Fiberglass: Our high-quality fiberglass insulators include blockbuster brands like Guardian Building Products and Attic Guard Plus®. Both are perfect for your attic. Fiberglass products are non-combustible, water-resistant and easy to install. 
  • Spray foam insulation: Our unique range of spray foam insulation materials includes Guardian Building Products’ Air Tite System, which combines the benefits of foam and fiberglass. Spray foam is eco-friendly, structurally strong and ideal for small, inaccessible places.
  • Blown-in insulation: Cellulose insulation is as eco-friendly as it is effective. It will fill any nook, no matter how small. 
  • Radiant barrier: SolarGuard’s radiant barriers resist rodents, thermal intrusion and heat loss. They’re perfect to combine with traditional insulation materials. Doubling up your insulation will protect you from temperature extremes and outdoor noise.

Attic Insulation FAQ

How much insulation should I have in my attic?

Every insulation material has its own density and R-value. Your climate also plays a role in your choices. Washington, DC and Maryland attics should have an R-value of 38 to 60.

Should I remove old attic insulation before adding new?

It’s possible to add new insulation over old insulation, but it depends on the condition of your existing material. A contractor can inspect your insulation to detect leaks, infestations or asbestos and determine if it needs to be removed. 

How long does insulation last in an attic?

Well-installed insulation only needs to be replaced every 80 to 100 years. You’ll lose much of that life span through negligence, so make sure your insulation and roofing are regularly inspected for leaks and infestations.

When should I replace my attic insulation?

Rising energy bills are the first sign of inadequate insulation. If your bill skyrockets without a significant change in your HVAC usage, it could mean you have air leaks due to poor insulation.


You should also replace your insulation if it gets wet or moldy. If you’re in doubt, Accurate Insulation can perform an inspection and provide expert advice.
