Blown-in fiberglass insulation is commonly used to reinsulate walls of existing homes.

Wall Insulation Systems

Wall insulation systems are designed to add insulation to walls in new or existing homes. With today's installation techniques, any enclosed wall can achieve an increased R-value.

Adding blow-in fiberglass insulation to an enclosed exterior wall is a cost effective way to add R-value to your home, protecting it from the loss of conditioned air while improving overall comfort and energy efficiency. Adding blow-in fiberglass insulation to interior walls can offer sound dampening and reduce noise transfer between rooms.

Fiberglass Batt Insulation

Batt insulation the most common and widely available type of insulation, and the type that comes to mind for most people when thinking of insulation. We install fiberglass batt insulation in open cavity walls (such as new construction or remodeling where we can access the inside of the wall). Batts are available in widths suited to standard spacing of wall studs, and attic or floor joists. Batt insulation: 

  • Has excellent acoustics
  • Is noncorrosive
  • Does not absorb moisture
  • Unfaced batts are noncombustible
  • Won't settle over time
  • Is lightweight
  • Is certified for superior indoor air quality (IAQ) performance


Blow-In Fiberglass Insulation


Blow-in fiberglass insulation is blown into walls of existing homes. This is done by creating small access holes in the walls and blowing the insulation into the space with a machine. The loose fiberglass insulation that is used for blowing can also be dense-packed into other closed-cavities:

  • garage ceilings under heated areas (where there is a room above a garage)
  • interior walls for sound control
  • between floors for sound control
  • upslope areas in attics

Blow-In Blanket Insulation

Blow-in Blanket Systems (BIBs) is used in open walls in new homes or remodeled spaces. The BIB system gives your home a custom-designed, seamless, thermally efficient, sound-reducing blanket that completely fills any void. Installed in an open cavity before it is closed with drywall, blow-in blanket installation allows loose insulation to be blown behind plastic in walls, completely filling gaps in the wall and providing a more complete thermal barrier.

The BIBs Hybrid System

Hybrid System

Installation of the BIBs Hybrid System combines the performance benefits of the Blow-in-Blanket® System and spray polyurethane foam. The BIBs Hybrid System

  • Saves Energy - this enhanced insulation system combines a continuous air barrier through installation of a thin layer of spray foam and the complete coverage of a BIB system, lowering the energy and fossil fuel demand of the home, which can save on heating and cooling costs
  • Sound Control - reduces unwanted outside noise
  • Improves Indoor Air Quality - including a continuous air barrier through the addition of spray foam helps reduce pathways for moisture, outdoor allergens, pollutants and pests
  • Professionally Installed - can be installed only by a certified BIBS HP contractor
  • Conforms to standard construction practices - increases R-values in standard stud cavities 




The OPTIMA gives homes a custom-designed, seamless, thermally efficient sound-reducing blanket that completely fills any void. The OPTIMA system is installed in new construction where fiberglass insulation is blown behind a special OPTIMA fabric. It can also be used for retrofitting existing sidewalls. This product is designed for closed-cavity applications only. 

OPTIMA insulation is a smaller fiber that allows the product to be packed more densely than standard blow-in insulation, creating a better blanket than other blow-in wall systems. 

The OPTIMA system

  • Is blown in dry. No drying required and the install is immediately ready for drywall.
  • Fills voids in cavities, allowing for a higher R-Values per inch
  • Provides excellent sound control
  • Leaves little dust for quick clean-up
  • Offers a more uniform application that other install methods
  • Won't settle
  • Is GREENGUARD® Children & Schools Certified
  • Is formaldehyde-free

Cellulose Insulation

Cellulose insulation is made from recycled newspaper and is a popular choice for many homeowners. As with fiberglass, cellulose insulation can be blown in to nearly any space including both attics and walls. Cellulose can also be dense-packed into other closed-cavities:

  • garage ceilings under heated areas (where there is a room above a garage)
  • interior walls for sound control
  • between floors for sound control
  • upslope areas in attics
