How much insulation does your attic need?

Monday, June 19th, 2017 by Gwen Hurd


If you’re reading this blog, it’s likely that you live in Massachusetts or Southern New Hampshire. That means you live in climate zone 5A. If you’re a gardener, you might be familiar with climate zones, as they help determine when to plant. Zone 5A is both colder and wetter than the majority of the populated country. For comparison’s sake, Miami is Zone 1A (hot and wet), LA is Zone 3B (warm and dry), and Fargo is Zone 7A (cold and wet).

If you experienced a cold winter in your home, it is possible you need a higher R- value of insulation in your attic. Heat rises, we all know this, so the home’s attic is typically where the majority of heat escapes in the winter or collects in the summer.

In the Southern part of the US, typical expected R value for attics is R-38. In the Northern part of the US, where we are, expected R value is R-49. So, if you’re reading this, you NEED R-49.

But at Dr. Energy Saver Northshore, we tend to go above and beyond. We generally recommend that homeowners increase R value to R-60. This extra insulation and R value will decrease energy bills and ensure that your home stays warm. 

The below photo is an example of what an attic looks like after being insulated, properly, to R-60.

Does this mean you should go out to your local home improvement store and buy a ton of fiberglass insulation at R- 60 and throw it onto your attic floor? No. Improperly installed insulation is completely ineffective and a waste of time and money. If you want your home to be warm, leave it to a professional.

Contact Dr. Energy Saver Northshore today for a FREE energy audit. We can get your attic up to R-60 the right way.
