Introduction To Blown in Insulation

Blown in insulation, also known as loose-fill insulation, is a popular choice for many homes. This type of insulation gets its name from the method of installation, where materials are blown into walls, attics, and crawl spaces. It's a go-to option for improving energy efficiency and noise reduction.

Understanding The Types Of Blown in Insulation

Different materials make up blown-in insulation. The most common include:

  • Fiberglass: Made from fine glass fibers, this type is lightweight and has good thermal resistance.

  • Cellulose: Comprised of recycled paper products, cellulose is eco-friendly and often treated to be fire-resistant.

  • Mineral Wool: This includes rock and slag wool, with excellent fire and soundproofing properties.

Reasons For Removing Blown-in Insulation

Various situations call for the removal of existing insulation. These may include:

Reason for Removal



Insulation that is old or compacted loses its effectiveness.

Water Damage

Moisture can cause mold growth and reduce insulation quality.


During home updates, insulation may need to be replaced to meet new standards.

Pest Infestation

Vermin can nest in insulation, necessitating its complete removal.

Safety First: Preparing For Removal

Removing blown in insulation requires careful preparation. Safety is the top priority. Before starting the removal process, you must prepare by gathering the right gear and setting up your workspace.

Personal Protective Equipment (PPE)

Protecting yourself is crucial when removing insulation. You must wear the following personal protective equipment:

  • Goggles: Keep eyes safe from loose particles.

  • Dust Mask or Respirator: Avoid inhaling fibers and dust.

  • Gloves: Protect hands from irritation and cuts.

  • Long-Sleeve Shirt and Pants: Prevent skin contact with insulation.

  • Disposable Coveralls: Optional for extra protection.

  • Head Cover: Keep hair free of debris.

  • Sturdy Boots: Ensure safe footing in the work area.

Securing The Work Area

Before removing insulation, secure the work area:

  1. Clear the area of furniture and cover items that can't be removed.

  2. Use plastic sheeting to seal off the space and contain debris.

  3. Place warning signs to keep others away from the area.

  4. Prepare disposal bags close by for easy insulation removal.

Importance Of Proper Ventilation

Good ventilation is key to a safe working environment:

  • Open windows and use fans to circulate air.

  • Make sure the area is well-ventilated before starting.

  • Consider using an air purifier to capture airborne particles.

Choosing The Right Tools For The Job

Embarking on a DIY project to remove blown-in insulation requires the proper tools. Without the right equipment, the process can be difficult and unsafe. So, let's ensure you're well-equipped for the task at hand.

Insulation Removal Vacuum

A powerful insulation removal vacuum is your main weapon against old insulation. It quickly sucks up the materials, making cleanup a breeze. Make sure the vacuum you select can handle the insulation material and volume you need to remove.

Other Essential Tools And Materials

  • Heavy-duty trash bags to hold the old insulation.

  • A sturdy ladder to reach high places safely.

  • Dust masks and protective clothing to shield against tiny particles.

  • Goggles and gloves for eye and hand protection.

  • Lighting equipment if you're working in dim areas.

Renting Vs. Purchasing Equipment

Consider the frequency of your insulation removal tasks before investing in equipment. Renting is cost-effective for one-time jobs. Purchasing makes sense if you do this regularly.
