How Long Does Insulation Last In The Attic?

How old is your home? When was the last time you were up in your attic, evaluating the effectiveness of your insulation? 

Insulation isn’t something most of us think about on a regular basis. But if your energy bills keep rising, you might have an insulation problem.

Like everything in your home, insulation is only designed to last for so long. It wears down. It can degrade. And depending on when it was made, it might not be as effective as newer products on the market today. 

Do a little research online and you’ll find sites that claim insulation can last for 100 years or more. The International Association of Certified Home Inspectors states batt, loose fill, fiberglass, and cellulose insulation can all provide 100+ years of warmth.

But this is in perfect conditions. And we all know our homes are rarely perfect. 

• Has your roof ever leaked?
• Do air leaks exist in your attic, allowing water and heat and cold to seep in?
• Have critters ever roamed through your attic?
• Has moisture settled in, causing biological growth to appear?

Insulation is disturbed for a variety of reasons. Even settling with age can render insulation ineffective. And these gaps, leaks, and other problems all can take its toll. 

How effective is your insulation? Aren’t sure? Maybe it’s time for an energy audit. 

Upgrading your insulation is one of the best ways to create a tighter envelope in your home. We recommend both fiberglass and cellulose blown-in insulation, depending on your needs. Both are easy to install, fills in gaps and holes and aids in creating a more comfortable living environment. Both can help protect your home for many years to come.
