What Is Cellulose Insulation
Written by Barrier Insulation Inc

What Is Cellulose Insulation?

When installing insulation in an attic or closed wall, the most popular choice is blow-in cellulose insulation. Other popular options include blown-in fiberglass and fiberglass batts. However, loose-fill cellulose is still the most cost-effective and practical solution.

What Is Cellulose Insulation?

Cellulose insulation is a wood and paper product used to fill empty spaces to prevent the transmission of cold and heat in a house. With a consistency similar to feathers, it is dense, clumpy and thick. It can be installed into enclosed areas and can go around obstacles such as ducts or wires. Commercial cellulose insulation is derived from materials like cardboard, recycled newspapers, office paper, and other common waste paper products. Therefore cellulose insulation is a very eco-friendly product.

How Cellulose Insulation Is Blown Into The Home

Homeowners most often use loose-fill cellulose insulation. It differs from other kinds of cellulose insulation that is designed to be blown onto open walls in a similar way to spray foam. With loose-fill cellulose insulation, moisture gets introduced into the spray assists in sticking cellulose to the wall. But with loose-fill insulation, the cellulose is dry. When filling finished walls, holes are drilled into the drywall or plaster permitting access of the blower nozzle. In attics, it is blown in alongside the joists. it can also be utilized to fill in existing cavities in the joists that have no insulation or added as a layer on top of fiberglass insulation or batts.

Cellulose Insulation Pro’s

  • Cellulose insulation stands up well to vermin and insects
  • With finished walls, loose-fill cellulose insulation is one of the very few ways you can successfully add insulation
  • Loose-fill cellulose insulation settles to conform around obstructions in attics and walls.

Cellulose Insulation Cons

  • Over time once the insulation has settled, it can form pockets where there is no insulation.
  • Cellulose soaks up moisture when placed in enclosed areas and takes a great deal of time to dry out.

Is Cellulose Considered Green?

To a certain extent…Up to 85 percent is made from recyclable materials. But the remaining 15 percent is less than ideally green as it contains chemicals such as borate to treat the insulation. As a rule of thumb, it would be fair to say it cellulose loose-foam insulation is not perhaps as green as it is sometimes made out to be.

How To Insulate Finished Walls
Written by Barrier Insulation Inc

How To Insulate Finished Walls

Modern homes usually come with insulation contained within the cavities of the walls as standard. But for houses built through the 1980s, this was not always the case. Older houses often have no insulation whatsoever, resulting in extremes of temperatures inside the house should you happen to reside in harsh climates with extremes of temperature. this can mean the heating or cooling system in the house is being overworked causing wear to the system and increased energy costs. With no insulation, energy seeps through uninsulated ceilings and wall cavities that are hollow.

Retrofit Wall Insulation

This is a much-discussed subject as there is no one correct answer. The only way to decide is via a cost-benefit analysis. Sometimes the cost of the addition of insulation may exceed the cost of the energy you save. Although uninsulated walls are never eco-friendly, it may be the only viable solution to remove the drywall, insulate, install the drywall and paint, once again.

Injection Foam Insulation

The main advantage of foam insulation versus fiberglass insulation is foam resists mildew and mold better than batt roll fiberglass or loose fill. Another plus is it’s strong expansion properties mean it can be forced into difficult areas. it is similar to those individual cans of foam insulation you can purchase from a hardware store but it is a lot more efficient. However, it also has the advantage of being the best choice to avoid wall damage. That said you will have to create holes for the foam to be injected in too. They will need to be filled, patched and painted to finish the job.

Remove Drywall & Install Roll Fiberglass

This is a very messy procedure but it is simple and does a very thorough job at an inexpensive cost. The gypsum has to be hacked away, removing the drywall nails and screws, installing R-13 or greater fiberglass roll insulation and then performing a re-installation of the drywall. However, the benefit is you can be assured your walls are fully insulated.

Loose-Fill Blown-In Insulation

Cellulose insulation (blown in cellulose in this case) is actually a paper product with boric acid added foe dire resistance. It is injected into the cavities of walls in a series of holes drilled either inside or outside the walls. Many companies ff this kind of insulation but the drawback are it can settle and get caught up on obstructions in the inner-wall like boxes, plaster keys, and wires.

Blow-In-Blanket Wall Insulation

This a new patented construction process utilizing blower injected pellets made from fiberglass that can be used for either closed or open walls. On open walls, a sheath of fabric is attached to studs, forming a kind of cage that contains blown in fiberglass pellets. The pellets then form in a tight and dense manner, creating a highly effective seamless blanket that is ideal at stopping air infiltration. This is a professional process and at the moment is only offered by one manufacturer and sold by approved outlets.

Spray Foam Insulation Areas

There are various areas of your home or business that can benefit from the addition of spray foam insulation.  Spray foam insulation has the superior insulating properties like other insulators, But goes further to seal up air leaks.  This keeps your home more comfortable without  having to run the AC or heat all night and day.  The less you need your HVAC the more your save!

Attic Insulation

The attic is one of the primary areas that need to be insulated to keep your home comfortable and energy efficient.  As heat hits your roofing it heats up and transfers the heat into your attic.  Spray foam insulation installed in your attic will slow the heat transfer, keep your attic cooler, and reduce strain on AC ducts running through the area.

Exterior Wall Insulation

The walls of your home whether it’s brand new or years old play a big role in your home’s comfort.  The sun heats them along with gaps and cracks allowing air to move through them to and from the outdoors.  Having spray foam added will make rooms more comfortable and help save you money!

Crawl Space

Crawl spaces are the hollow areas under some homes in the valley.  They exist to allow technicians like plumbers access under the home to do their work.  Installing spray foam in the crawl space will help keep floors more comfortable and seal up gaps and cracks that cause drafts in your home.

Whole Home

Homeowners wanting to get the maximum effect and savings from installing insulation choose to get their whole home insulated.  Spray foam is the premium and most effective insulation type for nearly all areas of your home.  It is best to be installed in new build or during remodeling that involves the tearing down of sheetrock and removal of old insulation.

Spray Foam Insulation Cost Factors

Every home and business is a different size, layout, age, and quality of construction.  This variety of conditions makes it impossible to give a “one-size-fits-all” cost for spray foam insulation.  Homes that are smaller cost less than bigger homes and projects that only have the attic insulated cost less than whole home spray foam insulation.

Area Being Insulated

The bigger the area being insulted, the more spray foam will be used, and the longer it will take a crew to properly install.  This has a direct correlation to the cost of the spray foam insulation installation project.

Type Of Spray Foam

There are two main types of spray foam insulation, open and closed cell.  Closed cell spray foam does have a higher insulation value, but also costs more.  Most homeowners choose to use open cell spray foam insulation.

Thickness Of Spray Foam Layer

The thicker the layer needed for your insulation project the more spray foam mixture will be needed.  The water blown product is mixed at the spray tip and comes from our truck.  The thicker the layer the most it will cost.

Brand Of Spray Foam

There are various brands of spray foam insulation.  Barrier Insulation proudly carries the top quality spray foam insulation brands.  We install the durable and long lasting Icynene spray foam insulation for our customers.

We offer all the different types of attic insulation to fit every demand and every budget.  Insulating the attic is one of the most important areas of the home to insulate to reduce dependency on air conditioning and heating.  Read more about the types of attic insulation we offer.

Blown-In Attic Insulation

Blown In Attic InsulationOne of the better choices is blown in attic insulation. It is installed by techs that have a large hose and shoot the insulation into the attic. They have training to create an even, uniformly deep layer of insulation. This is done by using a large air driven machine that churns up the material into chunks and then blows them up the hose and into the attic.

For blown material you have two main choices. There is cellulose and fiberglass blown in material. Both have advantages and disadvantages. With similar R values they both insulate well and are approximately 3 -4 R per inch. Fiberglass insulation is produced primarily from old glass or sand. Cellulose blown in insulation is made from recycled newspapers.

Depending on your application blown in insulation might be your only insulator in your attic, or you might use it in conjunction with other insulators to get the best energy efficiency. Blown in attic insulation sits on the floor of your attic as an even layer and helps keep your home cool in the summer and warm in the winter.

Batt Attic Insulation

Rolled Batt Attic InsulationBatt attic insulation is pretty straight forward to install as it is rolls of material typically lined with a paper backing. They are made from interweaving fibers that are long and have adhesive qualities. This means they stick to each other and stick together as a grouping. Batt insulation is made from two source materials, cotton and fiberglass. Cotton batts are made from recycled denim jeans. Fiberglass batts are typically made from sand or recycled glass that is processed into the insulating strands and fibers.

To install the batts they must be cut to fit each and every space they will be installed in. Even with the best of intentions there are tricky spots around corners, pipes, wires, junction boxes and other areas that end up having gaps. This means there are areas that simply are not insulated as well as other insulation options.

Spray Foam Attic Insulation

Spray Foam Attic InsulationOne of the most energy efficient types of attic insulation is spray foam. It comes in two types that have pros and cons. There is open and closed cell spray insulation. A larger percentage of homes were built with the HVAC and duct system in the attic of the home. This means that if your insulation is sitting on the floor of your attic, your system is having to work harder. Moving the “envelope”, or area of your home that is climate controlled, to the roofline can greatly increase your energy efficiency. Spray foam allows this envelop to be at the roofline, and helps fill in all the areas that batt insulation can struggle with.

Highly trained and skilled insulation technicians can spray the foam so there are no gaps or voids in the layer of insulation covering the attic ceiling. This means that the ducts carrying your hot and cold air to heat and cool your home are working in a more moderate climate. That translates into less energy being used to keep your home comfortable all year long.

Radiant Barrier Attic Insulation

Radiant barrier insulation provides an additional layer of protection to keep your attic and home more comfortable, and use less air conditioning and heating.  This type of insulation has the same goal of preventing heat from entering homes as traditional insulation but achieves the goal in a different way.  Instead of using thick layers of foam, loose insulation, or fiberglass batts it reflects the energy and heat with highly reflective surfaces.

It can be installed as a foil backed insulation board or it can be installed by spraying a highly reflective product onto the bottom of the roof decking in the attic.  Barrier insulation installs R-Max radiant barrier and HeatBloc Ultra spray radiant barrier.

The Best Attic Insulation

Clearly the best attic insulation really depends on your home and your needs. If you don’t have any ducts or HVAC system in your attic and you don’t plan to finish or use the attic space, you might consider one of the less costly insulation types. However if you have ducts in your attic and want to keep your home as energy efficient as possible using spray foam might be a more costly, but better long term investment. Having local attic insulation experts come to your home and help you develop an effective and budget friendly insulation plan for your home is the only way to get the best attic insulation for you individual needs.

How Much Does Attic Insulation Cost in Phoenix?

The average attic insulation installation cost in Phoenix is $915 according to HomeAdvisor. Depending on the price of the materials used for insulation costs range between $665-$1,165 in 2019.

Is Spray Foam Insulation Worth It?
Written by Barrier Insulation

Is Spray Foam Insulation Worth It?

Spray foam insulation is worth the additional cost as it performs better and seals air leaks.  It’s R-Value is higher, so it keeps the heat out in summer and holds it in during summer.  In addition spray foam insulation expands into gaps and cracks to seal air leaks.  This means that your conditioned air stays in your home and the hot air with it’s dirt, dust, and allergens stays out.

Much like any investment in real estate choosing good insulation options is important.  A lot of people are searching for “Is spray foam insulation worth it?”.   Spray foam typically does cost a little more than other traditional types of insulation; so homeowners are trying to understand if the performance difference is worth the extra cost.  This post will cover some of the differences spray foam insulation has and why it is worth the additional cost for many business owners and homeowners.

6 Reasons Spray Foam Insulation Is Worth It

Homeowners, businesses, and even charity organizations who build houses have realized the value and advantage of spray foam insulation.  Spray foam insulation’s advantages include that it seals air leaks, offers better performance, improves indoor air quality, and even helps keep your home quieter.

1. Seals Air Leaks

One major difference between spray foam insulation and every other type is that spray foam seals gaps and cracks that let air move in or out of your home.  This characteristic of spray foam leads to many of it’s unique advantages and superior performance as an insulation option.

2. Lower Utility Costs

Habitat for humanity did a case study where two identical homes were built.  One with traditional fiberglass insulation and one with spray foam insulation.  After only 5 months of utility bills the house with spray foam insulation owed $547 dollars less in heating and cooling costs!

3. Superior Indoor Air Quality

As the air leaks are sealed off allergens and humidity from outdoors is kept outdoors.  This helps prevent mold in the home and pollen or dust from entering the home.  Many people and children react to both pollen and dust with mild to sever allergic reactions that can significantly impact their quality of life.

4. A Quieter Home

Another great advantage of spray foam is having a quieter and more peaceful home.  Your house is likely the place you come to escape the noise and busied activity of the day.  Hearing less of the traffic passing your home and what the neighbors are up to will leave you with a greater sense of relaxation.  Spray foam insulation helps keep the noise outside and can even help soundproof rooms inside your home.

5. Better Resell Value

When you invest in better materials in your home it is worth more money.  Spray foam insulation is widely know for its advantages and being able to list that you have the best insulation option helps fetch a better sale value if you decide to move. Best of all once your spray foam insulation is installed you’ll enjoy lower utility bills for the rest of the time you live in the home.

6. Improved Wall Strength

Spray foam insulation adds strength to the walls of your home as it solidifies.  This additional strength will help keep your home standing strong as your it ages and improve the longevity of the structure.  So in addition to keeping you more comfortable, lowering utility costs, it will help keep your home in better condition for longer.

How To Install Spray Foam Insulation
Written by Barrier Insulation

How To Install Spray Foam Insulation

To Install spray foam insulation you’ll need to select which type you want, cover windows and doors with plastic, wear protective gear, and follow spray foam installation guidelines.


Cooling and heating homes is costly and saving money is a priority.

Installing spray foam insulation provides homes with the best insulation you can buy.

This post will show you how the pros get the job done and save homeowners money!


How To Install Spray Foam Insulation

Spray foam insulation isn’t as easy to install as say fiberglass batt insulation.  There’s no hold up the section and staple it into place.  Spray foam is a two part water based spray that expands quickly upon contact with air.  You’ll need to have a plan, continue to spray, and ensure you change out the tips if you stop for more than 30 seconds.  Spray foam is installed best by trained and experienced professionals.

Step 1. Select Your Spray Foam Insulation

Spray foam is available in two main categories, open cell and closed cell spray foam.  Closed cell spray foam is higher performance, but is more costly. If you’ve seen those cans of foam insulation at the hardware store, it’s not what the pros install.  Canned spray foam is for filling in gaps and cracks around wiring or plumbing coming through your walls.

Step 2. Cover Windows & Doorways

Spray foam insulation by nature is sticky.  You don’t want to spray onto windows or past doorways and onto the floor.  Much like you do when you’re painting you’ll use tape to protect the widows, doors, and doorways.

Step 3. Wear Protective Clothing & Safety Gear

As much as you don’t need spray foam insulation on your windows, you don’t want it on your skin.  In addition you don’t want to breathe it in or get it in your eyes.  So a protective suit, googles, gloves, and a respirator are all necessary to safeguard your health.

Step 4. Only Apply To Dry Surfaces

Spray foam insulation is designed to be installed on dry surfaces.  If sprayed onto a surface that’s got greater than 20% moisture it will not stick.  The plywood, wall studs, and joists need to be measured to ensure they are dry enough for spray foam insulation.

Step 5. Plan Spray Foam Installation

As you cannot stop for more than 30 seconds you need to plan what sections you’re spraying and in what pattern.  Have the plan worked out in your head before you pull the trigger on your gun.  If you’ve got high sections that need to be insulated, make sure you have ladders set up before getting started.  It’s also a good idea to plan for ventilation to remove the fumes from your workspace.

Step 6. Spray Perimeter First

To apply it correctly and fill in the gaps and cracks that spray foam is famous for filling you’ll need to spray the top, sides, and bottom first.  Allow this to dry before filling in your center sections in voids between your wall studs.  It’s a good practice to do a large set of these perimeters on the walls in a room.  This will allow them to dry in succession and make it so you can start over filling them in where you started in the first place sooner.

Step 7. Fill In Sprayed Sections

Allow your perimeters to dry for a few minutes and then fill in the center sections of your spray foam insulation areas.  If you spray too soon before the first perimeter was applied you’ll impact your R-values and not get the full benefit of your spray foam insulation investment.

Step 8. Remember To Keep Applicator Lubed

It’s important to make sure you lube the applicator each time you replace a spray tip.  If you’ve stopped spraying for more than 30 seconds replace the tip and apply the lube to the gun.  Each gun has a different approach for this so follow the manufacturer directions on which lube to use and how to apply it.
