You layer up yourself with sweaters to stay cozy and warm in your poorly insulated home. While you bundle up your house’s heating and cooling system, it has to work overtime to fend off the cold temperature. The water pipe of your home can be at risk of bursting at the same time. It is especially true if your home is old construction and under-insulated.

For you and other homeowners like you, the solution to this problem could be blown-In cellulose insulation. It fills the wall studs and joints in-ceiling easily and quickly. The loose-fill product is a popular alternative, along with others like fiberglass batts.

Let’s delve into the details to find more about cellulose insulation and its advantages.

Blown-In Cellulose Insulation- An Overview

Cellulose insulation refers to the paper or wood-based type product. The experts mechanically blow it onto the house’s structural part onto the empty spaces to reduce the transmission of cold or heat.

Typically, the material is clumpy, dense, and thick and has feathers-like consistency. The critical attribute of blown-in cellulose insulation is that its shape and size easily fit into an enclosed area such as frames and walls. Moreover, it quickly adjusts around obstructions found in the attic and between ducts, wires, and walls.

You can source cellulose insulation from any cellular plant, such as sisal and corncobs. However, cellulose for attic insulation or commercial projects comes from wood or paper. Manufacturers use various discarded papers, including office paper, cardboard, waste paper item, and recycled newspaper.

This feature sets cellulose insulation apart from other Home Insulation products. As this type of insulation uses plant-sourced material or recycled papers, it is an eco-friendly product.

How Experts Blow Cellulose Insulation into the Home

Loose-fill cellulose insulation is often the most common option many homeowners can use. While it offers the same advantages for home insulation, it has specific differences compared to other cellulose insulation types. Unlike blown-in cellulose insulation that is blown onto the walls, loose-fill comes in spray foam; experts mix the moisture into the spray to make it more adhesive for the walls. The cellulose is thick and dry with loose-fill insulation.

Experts or home insulation pros drill the holes in the dry or plastered wall to fill them. The holes allow access to the blower nozzle. If your house needs attic insulation, experts blow the cellulose starting from parallels to the central joints.

They do it in two simple ways- first, by allowing cellulose to fill the cavities and joints that have insufficient insulation itself. The second way involves layering a thick form over the batts (on the top) of fiberglass.

Dry cellulose’s installation process includes the following steps:

  • Home insulating experts feed the packed cellulose bales into the hopper of a blower run by a motor. The machine fluffs up the cellulose using dense prongs and teeth.
  • The machine automatically blows the cellulose into the wall or attic through its flexible and long tubes, extending from the blower to its nozzle.
  • The experts then allow the cellulose to fill all the empty cavities and existing insulation. After this, they let cellulose settle for some time and keep it pressure-free.
  • The last step is for patching up and painting over the walls.

Benefits of Blown-in Cellulose Insulation

» Eco-Friendly

If you use other home insulation alternatives such as fiberglass, it is not as eco-friendly as cellulose insulation. It has fine particles that may irritate your skin. Not to mention, inhaling them can cause health problems as well. Plus, you need to cut it into small sizes to fit tight corners, penetrations, and irregular spaces that leave tiny gaps. The gaps may increase the heat and cold transmission.

Cellulose insulation, on the other hand, is 100% recycled paper and wood products. Hence, it complies with all the green certification requirements. As there are no irritants in it, you can use the material without any danger or risk. The insulation product has the ability to insulate all available inches of the space comprehensively. As a result, you can consistently uphold its R-value.

» Fire Retardant

Blown-in or loose-fill cellulose insulation is a fire retardant. Manufacturers treat it with non-toxic components like ammonium sulfate, boric acid, or borax. Cellulose insulation received a class one fire rating.

That is to say, loose-fill cellulose insulation is safe even if you use it near the recessed cans and light fixtures. However, it is better to consult an Insulation Contractor if your home has outdated wiring or you want to install it with a vintage light fixture.

» Affordable

Loose-fill cellulose is cost-effective compared to other insulation products. But it still offers a good R-value, which is about 3.5 % of the thickness.

» Withstand Vermin

Loose-fill cellulose insulation provides stronger resistance against vermin and other organisms that can affect walls and attic. The borates in it make them reasonably strong to stand against insects.

Why Using Blown-in Cellulose Insulation

There is no denying that blown-in insulation makes the best option for closed walls. It is especially true if your home doesn’t require remodeling in which you need to open up the wall and inject the insulation. For impenetrable walls, the conventional favorite product is cellulose insulation. That is why it has become more common.

For open walls, install fiberglass insulation. Using spray foam insulation is also possible here. You can use both fiberglass batts and blown-in cellulose for Attic Insulation because the joints are accessible and open. However, as cellulose insulation is easier to install due to less obstruction, people prefer it for attics.

» Summing Up

All in all, blown-in cellulose insulation offers several benefits and may last for decades. You must speak to pros like Conejo Valley Home Services to get the best solution for home insulation.

Brandon came out to do our electrical and it was nothing short of fantastic! We had another electrician out for the same issue earlier but they were unable to solve it. However, Brandon was able to troubleshoot and figure out the issue quickly while letting me know what was going on throughout the process. Very professional and cleaned up after as well.

I've been using conejo heating and air for everything for years. Today we had our electrical box replaced. Brandon and his team were very thorough and diligent in solving problems and servicing our home. He was very helpful, answered all our questions, and solved an issue we've been having for weeks. He communicated everything throughout and was very kind with our doggies! Loved having them do this for us and we are very thankful they were able to fix everything we needed.

We took bids from multiple contractors to replace our 26 year old hvac system. Conejo Services had a detailed proposal and a fair price. Communication was great start to finish, and Edvin and the crew were here on time, polite, neat and very efficient. The job was completed exactly when we were told. We are glad we chose this company.

We called Conejo Services for an issue with our garage door opening by itself. We worked for months with another Garage Door company that was never able to solve the problem. Tyler diagnosed the problem and was able to fix it at minimal cost. Besides being skilled and knowledgeable, he is very punctual, considerate, and personable. I would highly recommend using Conejo Services for their garage door division.

Miguel came to look at a water pressure issue we've had for awhile. After asking a few questions he diagnosed the issue in less than 1 minute. He then clearly laid out the solutions and didn't pressure me at all to make a decision to choose them. He was extremely knowledgeable but not at all condescending. I really appreciated him and the prompt service and clear communication from the team all around! The guys who came the next day to install were also great!

Heater was 18+ years old and would not turn on. Over the Christmas holiday, Conejo Valley arrived two days after my call at the appointment time. After some discussion, we decided to replace the heater rather than repair. They then suggested the AC be replaced as it was 22+ years old. The 1969 ducts and insulation were replaced and upgraded to today's standard. The house is quieter and stays warmer these winter days. We're certain the AC will run less and keep the house cooler on hot days. Thank you Conejo Valley Heating & Air Conditioning for a job completed in 1-1/2 days with no aggravation or troubles on our part - just pure enjoyment with our new system! We recommend them whole-heartedly.

I didn’t use the services of any one at Conejo because they were very nice to tell me that my problem (gutter clean up on a manufactured home) was not something they did. They did tell me what I needed to find.

Shout out to Gabriel Kepner with Conejo Services. Came out on Friday to service our dual system thermostat that was not working properly. Installed a different one that worked better, but found a better option. Returned on Monday with the newer thermostat and set it up and works perfectly. Norm Nelson
