If you’re like the majority of homeowners, you probably don’t give your home attic insulation much thought. It’s always best to repair before it’s too late. Attic insulation should be replaced on a regular basis to ensure that your home is energy-efficient and comfortable. Let’s discuss how often attic insulation should be replaced and the benefits of doing so!
Most experts recommend that homeowners replace their attic insulation every ten to twenty years. This is because fiberglass and other types of insulation can settle over time, which reduces their effectiveness. Replacing your attic insulation will help to keep your home warm in the winter and cool in the summer, saving you money on energy bills. It will also improve the indoor air quality of your home by preventing mold and mildew from growing.
How Often Do I Check Insulation In The Attic?
While most people don’t think about it, checking the insulation in your attic is important. You should check it at least once a year to make sure that it is still in good condition and doing its job.
If you notice any of the following, then it’s time to replace your attic insulation:
- It has started to sag or falls down
- There are noticeable gaps or holes
- It is starting to yellow or discolor
- You can see mold or mildew growth
The Lifespan of Types of Insulation Materials
- Fiberglass: 15-20 years
- Cellulose: 20-30 years
- Rock wool: 25-40 years
- Mineral wool: 30+ years
It’s important to note that the lifespan of your attic insulation will depend on the type of material. For example, fiberglass insulation has a shorter lifespan than cellulose or rock wool insulation. If it isn’t damaged by moisture or mildew, fibreglass insulation can persist for 80 to 100 years. If you’re not sure what type of insulation is in your attic, it’s best to consult with an insulation installer. They will be able to tell you how long the material should last and whether or not it needs to be replaced.
