Utilize our great energy smart green service: Blown in Cellulose and Fiberglass Insulation
We offer both fiberglass and cellulose blown-in. Cellulose is a popular alternative to fiberglass insulation. It is a natural wood product, and 75% of what it's made from is recycled newspaper. Fire-retardant chemical additives give the material a class-1 fire rating, making it a very safe product. Homeowners can usually realize a 20% to 50% savings on all their future utility bills! In newer homes, with fiberglass insulation already installed, cellulose can be installed over the fiberglass for increased savings.
Once you find out what is old insulation, if any, is in your walls, you may find that the current materials may make it difficult to blow in new insulation. Using a filling tube, you will need to drill a hole large enough to push the tube through each stud bay. Looking at the stud bay, you holes should be about 1/3 to 1/2 way up. You will need a hole above and below blocking if the stud bays have horizontal blocking installed. The holes should be about 2 inches in diameter, while making sure that it matches the size of the filler plugs you are going to use to fill the holes after blowing.
You will need to remove one row of siding to drill the holes. Be careful when doing this so that the board can be replaced. This beats drilling holes through the siding and having to patch up each one that shows.
Filling tubes fill walls more completely and densely pack the insulation, which gives better R value and keeps the insulation from settling. The filling tube itself is approximately 8 ft long by 1.25 inch diameter flexible vinyl tube that is taped to the end of the blower hose.
When in use, the filler tube is pushed into the hole you drilled in the stud cavity. Push the tube to the top of the stud cavity and turn the blower on. Remove the hose as it starts to bog down. You want to pack the cellulose as tightly as possible without clogging the blower. Repeat the process for the lower half of the stud bay.
When finished filling all the stud cavities, plug the holes with plugs made for this purpose and replace the siding board. You may also blow the cellulose in from the inside by drilling holes in the plaster dry wall.
You might find that the blower provided by the home center is not powerful enough to blow insulation into wall cavities. In this case, you may want to rent a blower to do the job.
You can also blow the cellulose in with using the fill tube. We recommend two holes per stud cavity in this case. The nozzle of the blower is pushed through the hole, and insulation is blown in until back pressure and/or bogging of the blower occurs. You then shut the blower off and remove the nozzle.
