Spray foam insulation, which was created in the 1940’s primarily for aircraft, has been improved upon over the years and become a staple in residential and commercial construction.

Spray foam insulation can be used as an air barrier, decreasing air leakage in a home or building. Its use will decrease the risk of mold or mildew growth, and the formation of ice dams in colder climates. 

Spray foam insulation, used to insulate and create air seals wherever it is applied, is made with 2 liquids. When combined, these liquids create a chemical reaction and expand up to 100 times its size. There are 2 types of spray foam insulation, open and closed cell spray foam. Open cell spray foam is low density and allows water permeability. This spray foam is typically used in walls and under crawl spaces. Closed cell spray foam has medium density and repels water, making it a FEMA-approved flood resistant material.

Open Cell Spray Foam Insulation Benefits

Open cell spray foam insulation is a more economical option and costs significantly less than closed cell spray foam insulation. Fortunately, it is not a food source for mold, and is forgiving of long-term creep and seasonal movement within the home. The open cell spray foam can also add the additional benefit of drowning out sound. 

Closed Cell Spray Foam Insulation Benefits:

Closed cell spray foam insulation is recognized by FEMA to be a flood resistant material. Unlike open cell spray foam, closed cell spray foam insulation can be applied at extremely cold temperatures and can be used in smaller spaces. Closed cell spray foam is more durable and impact resistant. 

Spray Foam Insulation and Global Warming Potential

According to the EPA, “The Global Warming Potential (GWP) was developed to allow comparisons of the global warming impacts of different gases. Specifically, it is a measure of how much energy the emissions of 1 ton of a gas will absorb over a given period of time, relative to the emissions of 1 ton of carbon dioxide (CO2). The larger the GWP, the more that a given gas warms the Earth compared to CO2 over that time period. The time period usually used for GWPs is 100 years. GWPs provide a common unit of measure, which allows analysts to add up emissions estimates of different gases (e.g., to compile a national GHG inventory), and allows policymakers to compare emissions reduction opportunities across sectors and gases.”

Blowing agents are the gases that expand the cells of foam insulation. Open Cell Spray Foam Insulation, and spray foam that uses water as the blowing agent, will have the least possible GWP with a score of 1. Blowing agents are the gases that expand the cells of foam insulation. Closed cell spray foam insulation uses synthetic blowing agents and has a GWP of 700-1000, which is considerably higher than its open cell counterpart.

If you are in the market for insulation, you may have a lot of questions on your mind. Adding or changing the insulation in your home is a big step and you should definitely know about all the different types and how they can each benefit your home. If you continue reading, you will find the answers to five of the most commonly asked questions from homeowners regarding the home insulation.

Will I Save Money by Adding Insulation To My Home?

Not only will you save money by adding insulation to your home, but adding insulation to your home also increases your home’s comfort and protects the environment by reducing the energy use in your home. It has been estimated that around 44% of every homeowner’s bills go to heating and cooling their homes. This is a huge amount of spending going into just keeping your home comfortable. It has also been estimated that homeowners have the ability to reduce their energy costs anywhere between 10% through 55% if they take certain steps. One of these so said steps are adding or increasing the amount of thermal insulation in your home.

How Much Insulation Should My Home Have?

When it comes to how much insulation you should have in your home, there isn’t a right or wrong answer that we can give everyone, although, we can tell you that if your home was built before 1980, you should definitely get it checked as most homes built before that time don’t have enough insulation. But as mentioned before, there is no definite answer on the type or the amount of insulation that you should have installed in your home because  different locations require different amounts and types of insulation.

The Department of Energy (DOE) recommends that if you are about to get insulation installed in your home, you should check the R-Value’s of your location.

What Is R-Value and Why Is It Important?

The R-Value, which is also known as “Thermal Resistance”, is the measurement of the insulation’s resistance to heat flow. This measurement is determined by the material type, thickness, and installed weight per square foot. For instance, the higher the R-Value, the greater the insulating power is within your insulation.

What Insulation Is Best For People With Allergies?

When it comes to allergies, your home’s insulation can make quite a difference. The best type of insulation you can choose if you or your family suffer from allergies is Closed-Cell Spray Foam Insulation. The reason that closed-cell spray foam insulation is your best option for those with allergies is that it has specific properties that help reduce the number of allergens that enter and circulate through our homes. It’s elements minimize the amount of airflow entering your home which ultimately keeps insects, pollen, and any other sort of pollution from entering your home.

Do I Need To Hire a Professional Insulation Contractor?

Professional insulation contractors specialize in the very aspect of installing insulation. It is important that you hire a professional so that it is ensured that your insulation is installed properly and to ensure you get the most out of your money. Professionals will also be familiar with any local codes or regulations that may be within your city limits.


It is important that you have the answers to any questions you may have regarding home insulation. Doing research on anything you have in your mind will always help but you can also contact Geo-Insulation and we will gladly answer any questions you may have.

When it comes to installing insulation in your home, it is important to know that you have a few options to choose from, fiberglass and spray foam. While both of these will insulate your home, there are significant differences between the two. If you are going to be replacing the insulation of your home soon or are just doing some research, there will be some very helpful information below that will teach you what you need to know about home insulation.

What’s The Difference Between Fiberglass Insulation & Spray Foam?

To start things off, there is quite a difference between the fiberglass and spray foam insulation. In fact, there are even two types of spray foam insulation, closed cell and open cell. Fiberglass insulation works by trapping air in its tiny glass fibers, which results in a slow transfer of heat. Open-cell spray foam is used mainly as an air barrier for your home, while closed-cell spray foam works as an air, moisture, and vapor barrier for your home. It is also important to add that closed-cell spray foam insulation can add up to 250% racking strength to your walls and roof. Both open and closed-cell spray foam can last around 60 years longer than fiberglass insulation.

Is There a Big Price Difference?

There is a difference in pricing between fiberglass and spray foam. Fiberglass insulation is used in around 85% of homes in America mainly because of the low cost of installation. While fiberglass installing can be done by basically anyone, a professional may charge around $0.40 per square foot. Spray foam insulation, on the other hand, has to be done by a professional and can run between $0.90 - $1.50 per board foot (1 ft x 1ft square at 1 inch of thickness).

What Are The Benefits Between Fiberglass Insulation and Spray Foam?

For fiberglass insulation, the benefits are few, its cheap and it can keep some heat from entering your home. For spray foam insulation, the benefits range depending on whether or not you choose to go with open-cell or closed-cell. Benefits for spray foam include: stopping air and moisture infiltration, adds strength to the structure of your home, it is permanent and will not sag, keeps dust and pollen from entering your home, as well as reduction of capacity requirements and maintenance.

You Get What You Pay For

Like anything else, when it comes to the insulation of your home, you basically get what you pay for. If you aren’t able to put too much money into the insulation of your home, then fiberglass is the way for you to go. Just know that if you go the fiberglass route, you are leaving your home open to contaminants and other harmful elements that spray foam could block out. You will also have to be replacing the insulation of your home in around 8 - 10 years. If you decide to go the spray foam insulation route, consider it a good investment in your home. While it can be more expensive, it has to offer, and you may not ever have to replace it again in your lifetime.

If you’re still undecided about whether or not to add new insulation or maintain existing insulation in your house, reading about the benefits of insulating your home should help you make the right decision. 

Insulating your home properly can help you save money, make your house more eco-friendly and much more.

Cost Savings & Quick ROI

Although a big investment at first, insulation actually provides cost savings by reducing energy that is normally lost through bare pipes, uninsulated valves or defective insulation. Insulation can reduce heat loss on hot pipes and surfaces by about 20 times. (A professional can evaluate the insulation and accurately calculate the actual loss incurred.)

While the exact monthly savings depends on the kind of system installed, it is generally accepted that a good insulation system has an ROI or payback period of around 6 months to 2 years. Once installed, an insulation system has a long life, some anywhere from 80 to 100 years! Regular maintenance will continue to help you save money for years to come.

Reduce Pollutant Emissions

An insulated home is a friend to the environment because it helps reduce the amount of fossil fuels burned to produce energy. This leads to fewer greenhouse gases, such as carbon dioxide and sulfur dioxide, being emitted into the atmosphere. These greenhouse gases contribute to global warming, and sulfur dioxide emission is a factor in acid rain.

Improved Appearance

As an added bonus, implementing an insulation system helps improve the appearance of the house. By covering any exposed plumbing lines and air conditioning, insulation provides a finished look to the home.

Fire Protection

Insulation combined with other materials also helps protect air ducts, firestop systems, electrical and communications conduits, and cables from fire.

Noise Control

Another important feature of insulation is its ability to reduce noise levels both inside and outside the house Because excess noise pollution can impact people’s health and productivity, insulation matters as it helps reduce noise to acceptable levels. An insulation system prevents noise outside from entering the house, absorbs noise from the house’s interior, acts as a sound barrier that prevents noise from escaping from one section of the house to another.

Prevents Corrosion

When temperatures are below ambient air, moisture can become a problem. Condensation can cause the insulation to become wet and corrode cold piping, ducts and other surfaces. A thick insulation system with vapor retarders helps keep surface temperature above dew point. This will help prevent damage to building materials from corrosion, and it also helps prevent mold and mildew growth.

It’s Getting Hot in Here | The Truth About Radiant Barrier Insulation 

There’s little you can do to escape the summer heat, even when you’re inside the house. The Texas sun is unforgiving, especially if you’re living in places like San Antonio or South Central Texas. Installing radiant barrier insulation in such locations is essential for living in relative comfort while also saving you money. 

Radiant Barriers Myths 

NASA uses radiant barriers to shield its spacecraft and equipment, and protect astronauts from the heat of the sun. This fact, however, has been twisted into the common myth that NASA invented radiant barriers. The truth is German businessmen Schmidt and Dykerhoff filed patents for reflective surfaces to be used as building insulation way back in 1925. 

Another myth positions radiant barriers as the one-stop solution for all solar radiation and fluctuating temperature problems. While radiant barriers can significantly reduce the temperature inside the house, you should use it as a part of an overall strategy to keep your home cool in the summer months. 

Radiant Barrier Sheathing 

Speaking of summer, as the sun’s radiation increases during the season, the temperature in your attic also rises. This heat heads down into the cooler areas of the house and that is the reason your home gets stuffy and hot in the summer.  

To reduce the effect of the summer heat inside your house, a radiant barrier in your attic is used. There are different ways to add a radiant barrier to your house, and a structural roof sheathing panel is one of the most common ways to do it.  

An OSB (oriented strand board) panel, an engineered wood similar to particle board, which is laminated with heat-reflecting foil on one side should do the trick to keep your attic and the house cooler. There are other forms of radiant barriers and most of them use aluminum foil with cardboard, kraft paper and plastic films.  

A quick discussion with an expert should help determine what suits your needs best. 

Why You Should Consider a Radiant Barrier 

A good radiant barrier should be able to reflect up to 97% of solar radiation, and the efficiency only increases with more heat. In a state like Texas, that means the attic heat can be reduced by up to 30 degrees Fahrenheit. 

The reduced heat equates to direct savings for the homeowner, who can save up to half a ton in A/C requirements, and it also improves the life of the ductwork of the house because it requires fewer cycles to keep the house cool. The reduced energy and repair costs make radiant barriers a must-have feature in warmer climates. 

Hiring a Professional 

Installing radiant barriers can get technical and it requires a professional to get it done right. Aside from wasting time and energy, you can incur additional costs when doing it on your own.  

In Texas, Geo Installation is the place to go for all your radiant barrier needs. The company has established itself as a leader in the state, and it offers cost-effective solutions to keep your home cool this summer.
