Your old insulation has probably settled over time and will leave you with climbing utility bills. Improvements with the materials over the past several years have allowed us to guarantee our insulation against settling. Now, no material should settle more than 1 percent over its lifetime if it has been properly installed and you have proper roof/attic ventilation. Our only requirement for this guarantee is that you have proper roof/attic ventilation.
Yes! Depending on how much insulation you have left and how much you add, you can expect to save 25 percent to 50 percent on your utility bills. This saving will continue throughout the year. The insulation keeps the heat from moving through it, it keeps it out in the summer time and keeps it in in the winter.
