Your home’s insulation serves many valuable purposes, including that it regulates the flow of heat transfer in both cold and hot climates. While insulation is manufactured to last a lifetime, there are cases in which replacing it makes more sense.
1. Insulation’s age
Most insulation has a longer lifespan than you might think. But when someone talks about insulation’s average lifespan, they’re talking about insulation in ideal conditions.
In general, spray foam, house wrap, and wrap tape insulation should last 80 years, if not more, while other types – including foamboard, loose-fill, cellulose, and fiberglass can last a century.
Knowing the age of your home’s insulation is essential for several reasons. For one, insulation has evolved to include many technological advances.
- Outdated materials may result in high energy bills compared to newer insulation with greater energy efficiency.
- The older insulation material may not be protecting your house from pollutants, irritants, mold – and more – which lead to health concerns for you and your family.
- It’s a good idea to have your insulation checked if you live in an older home or recently purchased one because it may be worn out, or made from material no longer used (or rarely used) in modern home construction.
- Homes 10 years old or more may not meet the highest insulation standards. If your home is older, then it’s a good idea to have a professional roofing and insulation contractor check the insulation.
Many things affect the lifespan of insulation, not the least of which is water damage. Roof leaks can cause your home’s insulation to deteriorate over time while forming harmful mold.
Blown insulation naturally settles over time and becomes less effective for Wyoming homeowners. Settling occurs when air pockets trapped between pieces of insulation during installation are lost.
The primary cause of settling is improper installation, but the problem is often remedied by raking the existing insulation to even it out or by adding even more insulation to fill the air pockets.
Professional insulation contractors understand how much insulation can settle and often counteract the issue by installing extra insulation through a process called dense packing, which allows more insulation fibers to fit in the same space.
Additionally, settling often occurs in crawl spaces, which typically have blown-in insulation. In many cases, additional insulation is needed to remedy crawl space settling.
Water damage is one of the most common causes of insulation degradation and can lead to the formation of mold and mildew, which poses potential health hazards to you and your family. Meanwhile, wet insulation becomes less functional and loses nearly half of its ability to inhibit heat transfer.
A specialist in mold remediation – and not a roofer or insulation specialist – is needed when moisture in insulation turns to mold. Professional mold remediation often involves using powerful cleaning agents to kill mold, as well as antifungal sealants to keep mold from growing back.
Insulation damage may also occur because of critters who live in your attic. Rats, mice, birds, and insects may become residences of your attic and cause plenty of damage to insulation. Old insulation provides a cozy spot for pests to create nests.
However, spray foam insulation – which forms a strong foam barrier – isn’t nearly as ideal for pests to nest in, and it does an excellent job of sealing cracks to keep them out for good.
The fluctuation of indoor temperatures is another issue that indicates new insulation is needed. When insulation shifts, outdoor air can enter the home and compromise your HVAC system’s ability to regulate the indoor temperature properly.
The Value of Proper Insulation in Your Home
Insulation acts as a barrier to protect your house from heat loss and gain. Made from a variety of materials, insulation provides many benefits to your home, including greater energy efficiency and lower energy bill.
Insulation also helps make for a healthier home because it keeps out potentially harmful pollutants and toxic substances, which may lead to serious health issues.
Make sure that you call a certified roofing and insulation specialist to check your home’s insulation while seeing if it meets the highest standards for energy efficiency and safety.
While you may notice damage and weak areas on your own, a professional will properly assess the insulation’s condition and help you decide upon the best course of action.
