Spray Foam Insulation Savannah, GA
Spray foam insulation or spray polyurethane foam, is undoubtedly one of the most effective ways to insulate your residential or commercial building. When spray foam insulation in Savannah, GA, is installed by a good spray foam insulation contractor, it will effectively regulate the temperature and air inside your building and more importantly help in energy savings. An added advantage is that it will increase the re-sale value of your home as well.
What is Spray Foam Insulation?
Spray foam insulation is essentially a mixture of two chemical components, isocyanates and a resin mixture. These are also known as the “A” side and “B” side of spray foam insulation in Savannah, GA. Side A which is made of isocyante (ISO) is also known as PMDI or polymeric methylene diphenyl diisocyanate. Side B is a resin mixture which includes many components- polyols, water, blowing agents, fire retardants, catalysts, surfactants and other ingredients. When these two components are mixed with each other they expand at least 30 to 60 times in size and volume.
Spray foam was invented by Otto Bayer in 1937. Initially it was used as a packaging material but subsequently it was used for other applications like cushions, shoe soles and industrial uses. It was only until 1979 that people started using it as a building insulation.
Spray Foam versus Other Types of Insulation
Traditional insulations like cellulose, fiberglass, mineral wool and radiant insulation have been around for a long time. The most popular types of insulation to be used in residential and commercial buildings are fiberglass and cellulose. Let’s see how they compare to spray foam insulation in Savannah, GA.
Cellulose insulation is made from newspaper or wood, old jeans or cardboard. Cellulose insulation is used to fill empty spaces in a house and this prevents the passing of hot air from the inside and prevents the entry of cold air from outside.
Blown-in cellulose can easily fill spaces in ducts and walls and it also fits into wall spaces. It is very inexpensive, however a major disadvantage is that it needs to be changed every 15 to 20 years as cellulose insulation settles down and creates pockets. This allows air to pass through it. Because of this, it absorbs moisture from the surrounding air increasing the chances of the insulation catching mold and mildew.
Fiberglass insulation, like cellulose insulation has been used for many years and it can either be in the form of loose-fill blow-in or pre-cut batts or rolls. Similar to cellulose insulation, it is cheaper than other types of insulation but it can settle over time and it still allows air to pass through it.
Other than this, fiberglass insulation cannot be fitted into small holes or used to seal walls. Since this insulation is made of fiberglass, if it is disturbed, the tiny glass particles can float into the air and cause respiratory illnesses or skin irritations.
Mineral wool insulation
Mineral wool or rock wool insulation is a superior type of insulation compared to cellulose and fiberglass insulation. It has an R-value of R-3.7 to 4.2 per inch.
However because of its composition, one demerit of mineral wool insulation is that the fibers can easily break off. This can enter the air in your home and cause respiratory issues.
Spray foam insulation in Savannah, GA, has a much higher R-value than other types of insulation. For instance the R-value of closed-cell spray foam insulation can go as high as R-6.5 or R-7. Unlike cellulose and fiberglass insulation it will not settle over time, or allow air to pass through it. Spray foam insulation is the only type that can form a complete air-seal. It is also much more durable and long-lasting and will not need to be replaced in a hurry.
Types of Spray Foam Insulation
Spray foam insulation in Savannah, GA, comes in two different types. They are essentially the same with a few differences between the two. Which one you decide to choose will depend on the end purpose. It is always better to speak to a professional spray foam insulation contractor in Savannah, GA for all your insulation plans and projects. The two types of spray foam are:
Open-cell spray foam insulation
As the name suggests, this type of spray foam insulation in Savannah, GA has cells that are not fully encapsulate. In other words, the cells have deliberately been left open. This makes it softer and much more flexible when compared to closed-cell spray foam insulation. It is an R-value of R-3.7 and is also less dense than closed cell spray foam insulation and weighs about ½ pound per cubic foot. When sprayed, it expands up to 3 inches in thickness. Because of its expansive nature, it is usually used in spaces that are difficult to reach and where closed-cell spray foam cannot be used.
Closed-cell spray foam insulation
In closed-cell spray foam insulation, the cells are completely closed, blocking off the chance of any air or moisture entering it. It is much sturdier compared to open-cell insulation. It is also much denser and expands up to only 1 inch in thickness. It has an R-value of R-6.5 to R-7, which are the highest R-values for any insulation material. The total weight of closed-cell spray foam is about 2 pounds per cubic foot. Closed-cell spray foam is mostly used where spaces are limited. It is more expensive than open cell spray foam.
What is R-value?
R-value refers to the ability of a material to resist the flow of heat. Naturally, if the R-value is higher the insulation properties will be better. The R-value of cellulose insulation is approximately R-3.5 per inch; the R-value of fiberglass is R-2.2 to 2.7 per inch.
The R-value of open cell spray foam insulation is R-3.5 per inch and closed cell spray foam insulation has an R-value of R-6.0 to R-7.0 per inch. Spray foam insulation in Savannah, GA is one of the best types of insulations that are available in the market. Because of its high R-value and ability to create an air seal, it proves to effectively meet most building codes and standards.
Is Spray Foam Insulation Worth It?
Since spray foam insulation in Savannah, GA is relatively expensive compared to other types of insulation, you may be wondering if it is really worth it or not. Spray foam insulation indeed has several benefits and you will notice that even though you initially spend a lot of money for professional installation if spray foam insulation in Savannah, GA, you will benefit in the long term. Some of its benefits are:
Installing spray foam insulation in Savannah, GA will automatically lead to energy savings. This is because spray foam insulation helps to keep the conditioned air inside your home. Your HVAC system will have to work a lot less and you will spend less on heating or cooling costs.
Both residential and commercial buildings that are insulated using spray foam insulation in Savannah, GA, are much better protected against mold and mildew. This is because one of the biggest advantages of spray foam insulation is that it acts as a moisture barrier. This greatly improves the quality of air inside your home and limits unnecessary moisture that leads to condensation issues.
Closed-cell spray foam insulation helps in adding structural integrity to building structures. It’s always beneficial to have extra support. When spray foam insulation expands, it adheres to the substrate in such a way that it’s as if it becomes one with the substrate.
Any spray foam insulation contractor will tell you that spray foam insulation in Savannah, GA has a higher R-value when compared to other types of insulation. It-s high R-value helps in meeting building codes efficiently.
Effective even when wet
When other types of insulation like cellulose or fiberglass gets wet, it can cause issues like mold or mildew. But this is not the case with spray foam insulation. In the case of closed-cell spray foam, water will not pass through it at all because the cells are completely closed and though open-cell spray foam allows water to pass through it, it will not soak it up like a sponge.
Long-lasting and eco-friendly
Unlike cellulose and fiberglass insulation that needs to be changed at least every 15 to 20 years, spray foam insulation will not need to be replaced anytime soon. This is because it does not disintegrate easily and essentially it will stand as long as your building is erect. This limits the amount of insulation that will go into landfills and because it helps to conserve energy, it will reduce your carbon footprint on the environment.
Does Spray Foam Insulation Off-Gas?
One of the biggest concerns with spray foam insulation in Savannah, GA is the problem of off-gassing. This refers to the toxic chemicals or gases that are released from the spray foam i.e. VOCs (Volatile Organic Compounds) and uncured chemical dust. If you ask whether spray foam off-gases or not, the answer is yes. But this is only until it is fully cured.
