Attic insulation and R-Values. Many of us rest easy knowing that we have R-49 insulation in our attic. Well...., perhaps you shouldn't rest quite that easy. There are lots of things that go on up in the attic and many times the insulation gets moved around and/or trampled on creating areas where the insulation is one thickness and another thickness somewhere else. There are studies out there that claim if you level the thickness of your insulation throughout the attic it can increase the R-Value as much as 50%. It seems as though in the areas where the insulation is not as thick as it should be is the perfect spot for heat to escape. We have read that the simple task of "leveling your insulation" can greatly improve its efficiency. This falls within the realm of home ownership maintenance. This tiny task can save you significantly.
