Causes of Insulation Damage | Koala Insulation of Michiana | Michigan

Mineral wool and cellulose home insulation typically last for 20 to 30 years. Meanwhile, fiberglass varieties can last for 80 to 100. However, this layer of protection can begin to degrade in much less time if it suffers damage. Below are some reasons you might need to replace yours early.

When Should You Replace Your Home Insulation?

1. Water Damage

Water is the primary culprit for most insulation damage. Roof leaks, plumbing leaks, and flooding due to groundwater can compact the material, making it less effective. Standing moisture also leads to mold and mildew growth. Fungus degrades the material over time. Once this happens, you will likely notice household temperature fluctuations, drafts, and increased utility bills. 

2. Pests

Wildlife and insects also cause considerable damage to insulation, especially in the attic. Rodents, in particular, chew on almost anything they can find. In fact, the word "rodent" comes from a Latin term meaning "to gnaw." Their two front incisors never stop growing, so they must chew on things constantly to keep them trimmed. In addition, they tear up pieces of home insulation and carry them away for use in their nests.

3. Fire 

A fire caused by a short circuit, lightning strike, or another event can also damage your insulation. Fiberglass varieties are fireproof, but paper-fiber-made cellulose, wool, and spray foam are all combustible under the right circumstances. They contain fire retardant chemicals, but they can still be damaged by combustion and smoke. Replace the insulation if you've experienced a fire in the attic, outer wall, or crawlspace.
