Your home inspector will have seen the amount of insulation in your attic, and although the amount of insulation may not fail a home inspection point, there are recommendations for the general areas that we live in (for example Southern or Northwestern climates of the united states). Since our homes in this wonderful state of Montana, experience the cold adventures of winter it is recommended that our attics have more than a common level of insulation.
The standard attic joist (the wood that insulation goes between) is 7.5 inches high. Older homes with older insulation may only have a portion of this height filled in with insulation. With our winter climate and the benefits of energy saving insulation fills, it is recommended to have 14 to 18 inches of insulation in the attic. This means that once properly insulated you’ll no longer be able to see the attic joists … rather a field of thick insulation that will save you money on your heating bill and keep you home far warmer!
