As a general rule, insulation should be replaced or modernized every 15 to 20 years. However, this timeline may be shorter depending on the type of insulation installed, the R rating of the original insulation, compression and movement over time, and if any damage has occurred. If the insulation is no longer working properly, it must be replaced before the age of 15. You'll know that it needs to be replaced if there are leaks in the insulation or if it's coming off the walls. Fiberglass block insulation is a great option for attics and other areas where insulation is needed.
The lifespan of attic insulation usually lasts between 10 and 15 years, but its lifespan can be affected by several factors, such as the weather, ventilation, and pests in your home. One of the best ways to keep your home warm in winter and cool in summer is to make sure the attic is properly insulated. It's easy to tell the difference: block insulation will look fluffy and blown insulation will look solid. Likewise, if the attic is poorly ventilated, heat and humidity can cause the insulation to deteriorate.
Some of the most popular types of insulation for attics are fiberglass blocks, loose fill cellulose, and spray foam. When used in an attic, fiberglass block insulation can help keep the attic cooler in summer and warmer in winter. This comprehensive evaluation will provide you with practical information about where your insulation may be failing and what difference a new or modernized insulation can make. If you have an older house, chances are that the attic insulation will be the same as what was installed when the house was built.
In fact, you can take a look at the insulation of your attic or unfinished rooms for telltale signs of disintegration. If you live in an area with extreme temperatures or high humidity, your attic insulation will break down more quickly. Older homes may be using very old or low-quality insulation, or the insulation may have been incorrectly installed. Pests can also damage attic insulation, so it's important to inspect the attic regularly for signs of infestation.
If you've lived in your home for many years, you might be wondering when is the right time to replace your attic insulation? Cellulose insulation is environmentally friendly and more effective at blocking air than other types of insulation. However, the insulation from fiberglass blocks can start to peel off after 15 to 20 years, so if the insulation was installed more than a decade ago, it might be time for a home inspection or energy audit. It's important to remember that replacing or modernizing your attic insulation every 15 to 20 years is just a general rule of thumb. Depending on your home's specific needs and conditions, you may need to replace your attic insulation sooner than that.
If you're unsure about when to replace your attic insulation, it's best to consult with an expert who can provide you with an accurate assessment.
