Common Insulation Service Questions

Yes, many professionals offer insulated siding for improved energy efficiency.

Consider energy performance ratings, durability, aesthetics, and ease of maintenance when selecting windows for different environments.

Once installed, injection insulation requires little maintenance, but periodic inspections for air leaks or moisture buildup are recommended.

Ideally, you can add new insulation to your existing insulation. However, some circumstances require you to remove old insulation before adding any new insulation: 

  • If the insulation is over 15 years old

  • If the insulation is wet or moldy

  • If it is vermiculite insulation

  • If you see signs of pest infestation

Removing old insulation is best left to a pro who can safely dispose of potential moldy or asbestos-ridden insulation.

Although fiberglass dust is generally not considered toxic, inhaling excessive amounts of it can lead to health risks. Irritation to the respiratory system, eyes, and skin are common effects of fiberglass particle inhalation. While short-term exposure to the dust may only cause temporary discomfort, long-term or chronic exposure can lead to more severe respiratory problems.

Proper safety measures, such as wearing appropriate protective equipment, including masks and goggles, should be observed when handling or working with fiberglass materials to minimize health risks. It is important to note that, unlike asbestos, fiberglass is not associated with life-threatening illnesses.
