Blown In Insulation

Blown In Insulation

This blown in insulation installation is for the attic. You will need to prepare the following materials before you begin.

Required Tools and Materials

Ladder
Utility knife
Staples
Hammer
Duct tape
Flashing
Protective goggles
Dust mask
Cardboard Baffles
Loose fill insulation
Insulation blowing machine
A helper

Step 1

Measure the attic and determine the R value. This will be R-30, R-38 or R-49. It may vary depending on your location. Purchase the appropriate insulation.

Step 2

Put on protective goggles and a dust mask. Make sure the recessed lights have flashing installed. Leave an open space of about 4 inches of flashing to the light.

Step 3

Get the knife and slice the flashing to the appropriate length. Shape this into a cylinder. Fasten the edge with some duct tape.

Step 4

Put this over the recessed light. Set aside a four inch space. Repeat the same procedure for the vented portions of the bathroom or kitchen.

Step 5

The next step for the blown in insulation installation are the baffles. Set this into place with the staple hammer. Place them where the roof rafters intersect with the ceiling joists. Set up the baffles only above the vents.

Step 6

Slice some baffles four inches over the insulation. Staple this on the hole.

Step 7

Get someone to help you load the insulation blowing machine.

Step 8

Begin on the farther parts of the attic. Move back and forth to ensure that everything is smooth and level. Do not fill up any recessed light parts or vents.

It helps if you utilize a measuring tape. For instance, if you are putting in R 38 fiberglass insulation, the measurement can be 16 inches deep. Ask your helper to remove the excess hose if it is in the way.

Step 9

Step the machine when you get to six feet from the hole.

Step 10

The last step is to put a piece of batt insulation at the access hole. Put the attic opening lid on.
