When it comes to home insulation, there is an increasing number of options for homeowners in Minnesota to consider. These insulation types can be installed by professionals, which is the recommended option, or they can also be do-it-yourself projects.
Unfortunately, many people in MN do not realize the work involved in correctly installing attic insulation. What may initially appear to be a very simple project can quickly become a challenge, particularly if there is any existing insulation in a home that has to be removed before the new can be installed.
Fiberglass Batt or Blanket Insulation
Fiberglass batts and blankets are seen in many older MN homes. Both options are relatively easy to install in the large open areas of the attic, but they become problematic around vents, pipes and electrical or heating components in the attic. They are also difficult to use in small spaces and often end up being pushed randomly into small places, resulting in a decrease in efficiency.
There are also options for cotton batts and Rockwool batts and blankets, both of which can be a problem if they become wet as they retain moisture and can become moldy.
Blown Fiberglass or Cellulose
This is a do-it-yourself form of attic insulation that involves renting equipment to blow loss fiberglass or other forms of insulating material onto the surface of the attic floor.
It is challenging to maintain a consistent depth of insulation, and this can lead to less efficiency insulating abilities. However, the blown fiberglass is very light, and the cellulose is heavy, which does have consequences for existing homes.
Spray Foam
The choice of professionally installed spray foam attic insulation provides a consistent level of insulation that is durable, resistant to mold growth and highly efficient.
It can be applied to the attic floor or to the underside of the roof, with the contractor assessing the home and making a recommendation as to the best option. This type of insulation is a no-hassle choice, eliminating the need for time, equipment rental or frustration on the part of the homeowner.
