Blown Insulation vs Standard Fiberglass Insulation

Blown Insulation vs Standard Fiberglass Insulation

April 19, 2019

blown insulation vs standard fiberglass insulation

When it comes to choosing the best type of insulation for your home, there are many factors to consider. Among the many options out there, it most commonly comes down to blown insulation vs standard fiberglass insulation. So, to help you find some clarity on the matter, the team at DFW Thermal Solutions is here to help you weigh some pros and cons.

Blown Insulation

Although batt insulation is the more commonly used of the two, blown insulation is quickly gaining popularity. Also called “loose-fill insulation,” blown insulation fills stud or joist cavities with any loose material that has a good R-value. Although there is a variety of materials to use for this process, the most commonly-used material is cellulose. This material is made from recycled newspaper, cardboard, and other wood-based materials. As the name suggests, the installation process involves mixing cellulose material with paddles and then blowing it through hoses attached to a mechanical blower. For further consideration, here are some pros and cons to weigh:

Pros:

  • Installation is quick and easy.  
  • Blown insulation is more effective in reducing air infiltration than traditional batt-type insulation.
  • The material used is non-flammable and moisture resistant.
  • It provides great sound control.
  • Retaining its original R-value, blown insulation will not settle or separate.

Cons:

  • The up-front cost of blown insulation is higher than standard batt-type insulation.
  • Blown insulation requires a special blowing machine for installation.
  • It can be difficult to measure the precise thermal rating, since the material is usually not uniform in thickness.
  • Blown-in cellulose takes a long time to dry out, meaning a roof leak or ice dam can wreak havoc on your attic or wall cavity.

Standard Batt Insulation

In contrast to blown insulation, standard batt insulation does not require special equipment like a blower machine for installation. As is implied by its name, this type of insulation uses batts or rolls, which are large blankets of insulation made of fiberglass or cotton. Installed by cutting the batts to fit properly between joists and wall studs, installation is a matter of laying down batts into the space like a puzzle piece. To compare this insulation option to blown insulation, here are some pros and cons to consider:

Pros:

  • You can perform installation on your own, since it does not require special equipment.
  • The up-front cost is cheaper than blown installation, as well as installation.
  • Batt insulation material is readily available and can be purchased without a wait-time.
  • It can be installed in virtually any area of your home.

Cons:

  • Adequate insulation may require several layers of batt insulation. Because this means stacking material with limited flexibility into oddly-shaped areas, it can be a frustrating and difficult task to achieve proper and thorough insulation.
  • Because batt material comes in pre-cut sizes, adequately covering oddly-shaped attics and crawlspaces can make for a challenging installation.
  • Batt insulation is more susceptible to moisture damage, since fiberglass is rendered useless when it becomes wet.
