Buying Guide: Attic Insulation

Insulation is a key factor when trying to get the most out of your energy dollars. By properly insulating and air sealing your home, you can save up to 20% on heating and cooling costs (or up to 10% on total annual energy usage)*. As you begin to review attic insulation solutions, there are a variety of factors to consider:

  • Where will the insulation be installed?
  • How accessible is the insulation area?
  • What is the level and effectiveness of the existing insulation?
  • How will the insulation be installed?
  • How much insulation is required?
  • What type of insulation will be installed?
  • How to find and seal any air penetrations?

Efficiency & Comfort: Attic Insulation

Attic Insulation can create a more energy efficient and comfortable living environment by making your home warmer in the winter and cooler in the summer. And, since the average home uses approximately 46% of consumed energy on heating and cooling the home, inadequate insulation and air leakage can have a significant impact an energy bill.

  • Maintains Efficiency: Blown-in fiberglass insulation never settles or deteriorates, maintaining the R-Value rating.
  • Prevents Air Infiltration: Attic insulation, combined with air sealing, will stop air leaks and maintain a more comfortable temperature inside.
  • Enhanced Thermal Performance: Blown-in insulation can be installed at any thickness or weight per square foot to achieve a desired R-Value.
  • Less Indoor Noise: Insulation absorbs and reduces noise transmission from the outside, making a quieter home.
  • Effective Coverage: Blown-in insulation can be applied in hard to access areas and on top of existing insulation, without sacrificing effectiveness.

Insulation is rated using a thermal resistance measurement known as an R-Value rating, which is a measurement of the resistance to heat flow. When insulating, the higher the R-Value, the greater the insulation efficiency. According to ENERGY STAR®, the recommended level for most attics in Maryland is to insulate to at least R-38 and up to R-60, an insulation depth between 12 and 22 inches (depending on insulation type).

Material Quality: Attic Insulation

Attic insulation can create a more comfortable living environment by helping to maintain a more consistent temperature throughout your home. However, the insulating material is an important consideration. BGE HOME provides blown-in fiberglass insulation for maximum efficiency, safety and longevity.

  • Maintains R-Value rating; never compacts or deteriorates
  • Non-combustible, non-corrosive, non-rotting
  • Resistant to mold, mildew and microbial growth
  • Reduces noise transmission
  • Prevents air infiltration

Environmentally Responsible Insulation
