Insulation Types
You wouldn't use a baseball bat to pound a nail, and you wouldn't use a screwdriver to change a lightbulb. Often times the right tool for the job makes a project much easier and longer lasting. The same is true of insulation. Here at Insulation Services we inspect the property and show you leaks in your home's insulation. Then we recommend the best type of fill for your home.

 

 

 

 

Features and uses of the three most common types of insulation are:

 

 

 

1. Batts and Blankets



Most often made of spun fiberglass, batts and blankets are used in floors, walls, ceilings and attics, both in new construction and retrofit applications. Batts are insulation blankets that have been cut to lengths for specific uses. Blankets are uncut rolls that can be cut to specification. Batts and blankets are available faced or unfaced.

 

 

Types Common Uses
Kraft-faced insulation Kraft paper attached to insulation with a thin layer of asphalt, which serves as a vapor retarder. Paper flanges on either side allow the batt to be stapled in place.
Unfaced insulation Slightly wider to provide a friction fit between framing members. It can be used between framing in new construction and it also can be laid over existing faced insulation to add additional R-value on post construction applications. Unfaced insulation should have a vapor retarder such as 4- or 6-mil polyethylene covering when used in exterior wall applications.

 

 

 

2. Rigid Foam Panels

Rigid foam panels can provide the highest R-value per inch of common insulation types. They are relatively easy to work with and can be installed to cover wood framing members rather than fitting between them.

Four main types of rigid foam insulation are:

 

 

Types Common Uses
Molded or Expanded Polystyrene (Bead Board)
  • Exterior sheathing
  • Interior basement walls
  • Suspended ceiling panels
  • Siding backer board
Extruded Polystyrene
(Blue or Pink Board)
  • Exterior foundation

 

  • Wall sheathing

 

  • Interior above-grade applications
Polyurethane and
Polyisocyanurates
  • Foiled-faced or exterior wall sheathing

 

  • Vinyl-faced for beam ceilings

 

  • Impregnated-asphalt for hot-moppedroof applications 
Semi-Rigid Fiberglass Panels 
  • Foundations below grade

 

 

 

 

 

3. Loose-fill Insulation

Used primarily in unfinished attics. Loose-fill is installed with a blowing machine or can be poured in, directly from the bag. Types of loose-fill insulation include: 
 

 

Types Common Uses
Fiberglass Fiberglass Insulation milled into small pieces and blown into place.

Rock Wool

Made from natural minerals like basalt or diabase.
Cellulose Shredded paper (usually recycled newspaper) treated with fire retardant chemicals.
