Attic Insulation 

There are many questions that arise when deciding to upgrade your existing attic insulation. Most often, we get asked: When is the best time to insulate our home? Do I even need to upgrade my existing insulation? Would the benefits outweigh the upfront costs? Where would it benefit the most to upgrade my insulation and what are the proper procedures? These are all great questions. Every homeowner should always do their own investigative research before considering the upgrade.

Consider the Time of Year:

When upgrading the insulation within your home in the midwest, the best time of year to complete would be directly before winter. This ensures the homeowner that the interior home temperature will remain comfortable when outside temperatures begin to dip below freezing. Timing may not always work out that way especially because insulation installation companies begin to book up faster in these months and scheduling a date quickly may not always be possible. To ensure you have a well insulated home before winter, it would be a good idea to complete the work in the mid-to-late summer months.

Evaluating your Existing Insulation

The average Homeowner doesn’t typically keep track or know what their existing insulation r-values are within their attic. Evaluating the existing insulation type, depth and installation practice is a great procedure to complete prior to considering your options. The best way to complete this evaluation would be to simply enter your attic and take notes on the following:

  1. Are there kraft faced batt’s installed?
  2. Are there baffles installed and installed correctly?
  3. Are the attic floor penetrations sealed with low expanding foam?
  4. What type of blown in insulation is installed, if any?
  5. What is the existing depth(in inches) of the blown in insulation, if any?
  6. Can you see daylight from your roof eaves? (Daylight is a good thing. It’s a good sign that outside air is being ventilated through the soffits).

We understand that not everyone is capable of completing the above checklist, and if that is the case, we would recommend that they ask these questions to their local insulation companies. Requesting pictures is also a good idea so that you may physically view these items for yourself.

Once all existing items are evaluated and documented, you may make an educated decision based on your personal needs and wants. We would  recommend requesting three to four different quotes from highly rated companies in your local area.

The Benefits From Insulation

Your home is constantly being conditioned with heating and cooling over the four seasons throughout the year. Completing any form of an insulation upgrade will benefit your expenditures in heating and cooling. Most older homes were built with little insulation because building codes at the time of their construction weren’t as energy efficient as today’s upgraded codes. The benefits will vary from home to home, but heat loss will be reduced and energy savings will be seen.

Not only should you see a cost savings in your energy bills throughout the year, but your existing roofing system should last longer. The sealing of attic penetrations, baffle installations and upgrading of your existing insulation can significantly reduce the heat and moisture within your attic. Completing this work will reduce heat transfer between the living space and the attic.  Also checking that exhaust vents are being vented out the roofing system is a good practice.  Moisture from these vents can create dark staining on the underside of the roof decking and eventually lead to premature decking failure.
