Is your attic insulation the right R-value and the right quantity for Michigan’s dramatic summer and winter temperature fluctuations? Improper attic insulation contributes to unwanted, seasonal heat gain and loss – not to mention energy waste. This is why a solid roof and adequate insulation are keys to whole-home comfort.
Not sure if your insulation is doing its job or not? Ask yourself the following questions:
- Is the home 15-years old or older?
- Are ice dams common winter occurrences?
- Are there strange temperature fluctuations from room to room?
- Do ceilings feel notably warm/cool to the touch?
- When you peek in your attic, does the insulation seem spotty, are there gaps, and/or can you see more than 1-inch of floor joist exposed?
If any of these answers are yes, your attic insulation may not be doing its job.
How Attic Insulation Works to Create Whole-Home Comfort
The attic is the ideal place to start when considering how and where to add or upgrade insulation in your home. In fact, energy.gov lists attics as the #1 priority for replacing or upgrading insulation because a significant amount of energy loss occurs through poorly insulated attics.
According to the experts:
- The average U.S. homeowners spend nearly $2000 per year on utility bills
- More than half of that is spent on heating/cooling costs
- Almost 25% of heat loss/gain occurs in the attic
Insulation works to slow conductive heat flow – that is the transference of heat from one space (or object) to another. During warm weather months, attic insulation keeps solar heat gain from the roof from displacing cool air circulating from your AC unit. In the cooler months, that same insulation prevents heat from escaping through the roof, forcing your heating system to work harder.
The result is improved, year-round energy efficiency and increased whole-home comfort.
How Much Insulation do Michigan Attics Need?
With insulation – quality is as important as quantity, with higher R-values yielding better insulating results. The state of Michigan is located in weather zones 5 & 6, which means our extreme temperatures require some of the highest R-value and insulation thicknesses in the nation.
There are various types of insulation. The most common are:
- Rolls and batts
- Spray foam
- Foam board/rigid board
- Loose fill/blown in
There are advantages and disadvantages to each, so a licensed contractor should establish which is best for your household’s needs/budget. Contact Victors Roofing for your insulation questions and solutions!
