For the past 60 or so years the term "insulation" conjured up images of pink or yellow, fluffy stuff called fiberglass that has been widely used in walls, floors, attics and basements. Thanks to the field of Building Science and the use of scientific instruments used for diagnostic testing we now know that fiberglass is no longer the only material available on the market - nor is it the most effective. In fact, it may be time to consider removing the fiberglass insulation from your home and here are the reasons why:
1) Mice, Squirrels & Stink Bugs are often found in attics, basements and crawlspaces which means they are living with you and using the fiberglass as nesting material. The dust that accumulates in your home is made up of debris from dust mites, fiberglass particles, debris from rodent & insect activity (including urine & feces as well as the decaying dead bodies of mice & insects). If you have a forced air system for heating and/or cooling, you could be distributing contaminants throughout your home and creating unhealthy indoor air for your family to breathe.
2) Mildew & Mold form due to condensation which is the formation of moisture on surfaces where warm, moist air comes into contact with cooler, drier air. The air you work so hard to heat and cool in your home gets filtered by the fiberglass as it leaves the building. As long as there is temperature difference between indoor and outdoor air, the likelihood that moisture will form and produce mildew increases.
3) Heating fuel usage depends on the temperature outside and also on how well the insulation in your building is performing. Although it may not seem as though your heated indoor air is finding its way out of your home, it is - unless you have utilized professional air sealing techniques. Fiberglass insulation allows air to pass from your living space through any hole it can find - including drywall seams and recessed lights.
In each of the above instances, the removal of degraded fiberglass insulation and debris that accompanies it will produce beneficial results. Proper air sealing and insulation materials and techniques will:
* Reduce rodent & insect activity by sealing up their points of entry and, IF they do find their way inside, repel them leading to much more healthy environment.
* Improve indoor air quality by reducing or eliminating the conditions that create condensation that lead to mildew and mold.
* Reduce the amount of annual heating fuel usage and improve the overall comfort of your home.
