Animal Infestation

Animals such as rodents and birds can also cause damage. The material becomes comprised when animals create a nest or chew through the insulation.

Frequently Asked Questions 

How To Prevent Exposed Insulation in the Basement?

Most of the reasons your basement insulation could get exposed are out of your control. However, there are still measures you can take to prevent this from happening.

First, make sure that your basement insulation is installed correctly. And don't forget to make it a habit to check your house's insulation now and then to catch problems early. 

Why Should You Insulate Your Basement?

In addition, insulating your basement can help protect any stored items from exposure to extreme temperatures. If you have a finished basement, insulation can also help reduce noise levels and create a more comfortable living space. 

What Insulation Methods to Avoid in Basements?

Insulation materials that are porous and quick to absorb moisture are not suitable for basements. Some examples of this type are fiberglass and mineral wool rolls. Take note that fiberglass is not moisture-resistant. 

What Are Health Hazards Posed By Exposed Insulation?

When insulation is damaged or installed improperly, it can release dust and fibers into the air. If these particles are inhaled, they can irritate the lungs and cause respiratory problems and even potential cancer risk.

In some cases, insulation can also be a breeding ground for mold and mildew. When mold spores get released into the air, they can cause allergic reactions and respiratory problems. 

When Should You Replace the Insulation In Your Basement?

Replace severely damaged insulation or when a professional advises you to do so. As time goes by, the insulation in your basement can become compressed.
