• Blown Fiberglass : Advantages :inorganic glass fiber, light (density) weight and has a long life expectancy. Disadvantages : light density allows air to move readily through fiber causing degradation of R-value. In addition Mice like to nest in it, also degrades R-value and sometimes requires removal due to mice urine contamination, which can be allergenic.

In most cases insulation alone is not the answer for comfort,health,and economy issues.

Each homes attic  presents a new set of parameters that have to be considered for the optimum solution to be selected. For instance some homeowners may have  a problem with humidity control. This is usually a combination of attic air and duct sealing. If there are HVAC ducts in the attic that leak as little as 15%  it can cause a 50% loss  of cooling capacity.

In addition to insulation there are other considerations. Venting and sealing of your attic is just  as important as the insulation. You may have adequate insulation but due to stack effect the air leakage from your basement or crawlspace up through your home to the attic can result in high energy bills. Other conditions like dry air causing  static electricity, present in the winter and hot humid conditions in the summer, are all pieces of the attic  puzzle that we can improve.

Inadequate venting on the other hand can cause moisture to build up in your attic causing mold and rot. Ruining the life of your roof, plywood and rafters and creating a possibility of poor air quality in your home.
