When was the last time you checked on your attic insulation? Atlanta is home to humid summers and mild winters. Most of the year, you may be able to get away with your aged attic insulation. However, when the summers and winters come, problems with your attic’s insulation may start to surface. 

Attic insulation in this part of Georgia is critical to your home’s thermoregulation. It can mean the difference between having energy savings and paying through the nose for your gas and energy bills. 

While attic insulation can last for years, it will not last forever. When you start to notice leaks and unusually hot or cold spells in your home, it’s a sign. More specifically, it’s a sign that your insulation needs replacement or repair. 

However, how long does attic insulation really last in South Atlanta? Read on to learn more! 


Average Lifespan of Attic Insulation


Indeed, the insulation of your attic can last for decades. Attic insulation, regardless of material, should be able to provide you with at least 40 years of insulation. Under optimal conditions, you can stretch this number to about 80 years. 

Nonetheless, wear-and-tear does occur. Hardly are South Atlanta’s summers and winters beneficial for attic insulation. If you live in this part of Georgia, you need to have a smaller number in mind in regards to attic insulation longevity. 

To be on the safe side, you may want to consider inspecting your attic insulation after it reaches the 10-year mark. If you see no damage after ten years, check again after five years. 

If you’ve just moved into a property, the best person to get this information from would be your realtor. 


Why Does Attic Insulation Sustain Damage? 


The layer of your attic with insulation material can be damaged for several reasons. The most common ones are: 

  • Animals like rodents
  • Damage from roof repairs or any related construction work
  • Heat 
  • Moisture
  • Hail damage that has penetrated the roof (in some cases)
  • Ice buildup

When your insulation has been up for years, it can sustain damage owing to any of the above-mentioned factors. Usually, the damage is the result of chronic exposure to the above factors. 


A Radiant Barrier System: The Solution to Damaged Attic Insulation


A radiant barrier system is a layer of added insulation to your attic. It is made from high-quality aluminum and other reflective components. The aluminum and reflective materials can improve your attic insulation in two ways. 

During the summer, heat and UV light from the sun is reflected because of the reflective surfaces. This prevents heat and sunlight from causing damage to your attic insulation or overheating your house. 

A radiant barrier’s protection does not stop during the summer. Ice buildup is another common cause of damaged attic insulation. With a radiant barrier, no ice will collect and build up. As a result, your attic insulation remains intact. 

Overall, a radiant barrier system adds years to your insulation. And, of course, with proper insulation, you will not need to turn up your thermostat too high, nor will you have to turn up your AC or use a lot of electricity in the hotter months.
