How your insulation is installed is as important as the type of insulation that you use. The walls, ceilings and floors of your home are full of odd shaped cavities and obstacles like plumbing, air ducts and wiring. For your insulation to work effectively, it must be able to completely fill around these obstacles without gaps or voids.

"About half of all wall cavities in residential construction are nonstandard in width and height or obstructed with wiring, pipes and other things. Any void area in conventional batt installation can reduce the R-value significantly."

How Does Your Installation Fit?

Installation is critical in determining how insulation performs in your home. How well does it fit in different size wall cavities and around countless obstacles? Is it cut and patched in - or is it custom fit?

Cellulose is Custom Fit

Cellulose insulation is sprayed or blown into walls, filling every panel, every nook and cranny seamlessly, conforming to your house and surrounding you and your family with the best insulation there is. Cellulose provides you with walls that are fully and tightly insulated, forming a monolithic thermal barrier - no gaps, no voids, no drafts.
 

Fiberglass is Haphazard

Fiberglass batts are cut and pieced together into your walls, filling space as best as they can. Fiberglass leaves gaps, voids and areas of compression, which causes drafts and a loss of R-value. Tests conducted by a fiberglass manufacturer reveal that the actual performance of batts can be 14% to 45% less than their labeled R-value when gaps and voids associated with normal batt installation are considered¹.
