Is your home colder than usual in the winter or warmer than normal in summer? It may be time to remove the insulation in your attic. It’s also known that old insulation can be a health risk and should be monitored closely.
Many homes feature attic insulation for better temperature management. The insulation material can be asbestos, blown-in insulation, or fiberglass batt, depending on the age of your home. In this article, you’ll learn how to remove insulation from your attic efficiently.
Attic Insulation Removal Basics
Adequate insulation ensures your attic always remains at an optimal temperature. However, a poorly insulated attic can significantly reduce your home’s energy efficiency. Therefore, acting fast is essential if you have old and decayed insulation.
The removal process will vary depending on the type of insulation material and your experience level. However, it’s a demanding DIY project that will require adherence to strict safety measures.
The Attic Insulation Removal Process
The first thing you need to do when looking for how to remove old attic insulation from your attic space is to gather the equipment you need. Some of them include:
- A commercial-grade insulation removal vacuum
- Ten-inch vacuum hose (up to 150 feet long)
- A ladder six to feet in height
- Wall and floor coverings
- Protective gear for your nose, eyes, skin, fingers, and legs
- A dumpster
Once you have the equipment you need for the job, prepare your home for the impending mess. Cover up the wall and floor and ensure a clear path from your attic access to the door. Wear your protective gear to start the process.
The Process for Blown-in Insulation Removal
Follow these steps for blown-in insulation removal:
- Set up the insulation removal vacuum and run the hose to the attic.
- Climb into the attic to resume the removal process.
- Suck out the insulation from the walls and use a rake and dustpan to clear any remnant debris.
- Dispose of the collected insulation material in the dumpster.
The Process for Fiberglass Batt and Foam Insulation Removal
- Climb into the attic with some vacuum bags.
- Remove the fiberglass batt insulation or foam boards by hand.
- Roll them up and place them into the vacuum bags.
- Continue the process, filling up as many bags as necessary with the discarded fiberglass batt insulation.
The Process for Vermiculite Insulation Removal
The process for vermiculite insulation removal is the same as for asbestos insulation removal. Vermiculite insulation contains asbestos—a known carcinogen. If you live in a home built before 1970, you may have asbestos or vermiculite insulation in your home.
In this case, you should never attempt the removal process alone. Here’s how to remove insulation from your attic space if you have asbestos.
- Send a notification to the San Diego Air Pollution Control District.
- Contact accredited asbestos inspectors and contractors for testing and removal.
- Use one company for testing and another for removal to avoid conflict of interest.
- Move your family out of the home before the removal process begins.
Spray Foam Insulation Removal
You can complete spray foam insulation removal manually or using a special machine. We’ll cover both methods below.
Before starting the process, wear your mask and protect your eyes. The chemicals in spray foam can cause lung damage if you inhale the particles for long periods.
- Cut out the spray foam insulation with a saw or knife.
- Use a paint scraper or hard-bristled brush to reach spray foam in recessed areas and cavities.
- Dispose of the spray foam cut out carefully.
You can use a spray foam removal machine to remove the insulation in your attic. You’ll need to hire one of these heavy-duty machines as they are not your standard garage equipment.
- Connect the vacuum hose to the spray foam removal machine.
- Attach the vacuum bag to the machine to catch the insulation material you remove.
- Climb into the attic and begin the removal.
- Use the manual approach to cut out stubborn spray foam.
