additional options when insulating your home

Traditional:
We all have come into contact with fiberglass batt insulation.  It is a traditional way to insulate our homes, and is customary in Wisconsin and many other areas as well.   You will see this in your walls and also in your attic space.  Typically batt insulation comes in a roll which fits between the studs or framing of your home.  The roll is extended to cut the length you need.  The insulation is then fit by compression in the cavity in which it is installed.  If your home has a 6” wide exterior wall, batt insulation with an R value of 19 will be installed, and if you have a 4” wide exterior wall batt insulation with an R value of 13 is installed.  R value refers to the resistance of heat flow through a material.  The higher the R value the better insulation value, or resistance to heat flow through your wall, attic, etc. you will achieve.
 
Another form of traditional insulation is blown in insulation.  This is similar to batt but consists of fiberglass insulation which is in pieces and is blown into cavities in walls, floors and attics to fill gaps where air may infiltrate.  In many applications batt has been preferred over blown fiberglass options due to the settling of the blown product.
 
 
Spray Foam:
Spray foam refers to a polyurethane insulation product which is applied by spraying it onto the surface.  It will expand significantly to fill in gaps and cracks making it an option for weather-tight applications.  The product is available as an open or closed cell option.  The closed cell option acts as an air, moisture and vapor barrier as well.  For both open and closes cell the R value is approximately 6.5 per inch which is higher than a batt or blown product (3-4 per inch).  It also fills in the very small nooks and cracks to keep air infiltration at bay.  For this reason it is gaining popularity.  Other advantages are that it doesn’t promote mold growth and can be better for allergy sufferers.  The downside to spray foam is that it is significantly more costly to install than batt or blown fiberglass options.  Typical issues which arise with this product are related to improper installation.  It is imperative to have an experienced installer apply this product to gain full benefits.  If you have additional questions regarding these products feel free to contact our office directly.
