Things You'll Need:
- Hole saw Tape measure Blow machine Plugs
-
Step 1
Determine if you can easily remove and reinstall the exterior finish of your home. Generally, strips of vinyl siding can be removed and replaced easily. Aluminum siding is more difficult to work with.
-
Step 2
Measure from a corner of the home to mark the areas you will need to drill to access the wall cavities. Remember that the studs should be located on 16 inch centers. You will need to drill a hole for the nozzle of the blow machine, at each cavity.
-
Step 3
Blow in the insulation. The pressure required to fill the cavity will be dependent on the machine you are using. Make sure you are familiar with the blow machine and its settings.
-
Step 4
Repeat these steps around the entire home. Remember that you will need to drill a hole to access each floor level and that cavities that are split by window openings will require a hole above and below the window.
-
Step 5
Use plugs to seal the holes that have been drilled, once insulating is complete. With vinyl siding, you can simply reinstall the siding over the plugs. Aluminum siding will require that you paint the plugs to match the siding.
-
Step 6
When insulating attic spaces, simply blow the insulation to the required depth to meet local building codes. Work from the corners of the attic, back to the access area.
