What is Spray Foam?

Published by Rease at 5:14 PM under Blog

Many people have begun to hear the word spray foam as a buzzword in the insulation industry. This high-quality insulation is great for many applications and in some cases can be very cost effective. However, it's important to know what you are buying and in which situations this high-performance insulation makes sense.

What is Spray Foam?


This polyurethane foam is an expanding substance. It sprays on thin and expands to create a barrier. Open cell foam will expand more than closed cell, but that does not necessarily mean one is better than the other.
Closed cell foam only expands a little bit, but it creates an airtight barrier. It acts as an air barrier, thermal insulator, and moisture boundary. This type of spray foam is great for ceilings, but not for roofs. When used for roofs, it can trap moisture from leaks and condensate, which will lead to mold growth.
Open cell foam expands much more than closed cell because it is not airtight. The open cell foam allows air and moisture to travel through it, making this foam ideal for attic or roof decking. Instead of trapping the moisture like a closed cell foam would, this type of foam allows the moisture to travel through and dissipate, preventing rotting.

When Should Spray Foam Be Used?

Spray foam is an expensive material, so you certainly do not want to spend money on it unless you are going to see a return on your investment. Spray foam is great for new construction, or modifying homes in areas such as the ceiling, attic, or roof. Due to the high cost of the material, it is best to combine the foam with another type of insulation. Affordable Comfort created a Hybrid System that uses a small amount of spray foam paired with Cellulose insulation. This system allows you to get the high performance benefits of the foam without breaking the bank. If you were to insulate your entire home in spray foam, the cost would be too high to ever see a return on your large investment.

When Shouldn't Spray Foam Be Used?

Spray foam should not be used exclusively to insulate an entire home, due to the aforementioned high cost issues. You also wouldn't want to add spray foam directly on top of existing insulation.
Overall, spray foam is an excellent choice for insulating a structure. It is just important to know when and how to use it, as well as how much should be used in order to save money without sacrificing results. We here at Affordable Comfort are more than happy to walk you through the process.

What is Spray Foam Insulation?

Published by Rease at 4:53 PM under Blog

We here at Affordable Comfortable offer very high quality BASF Spraytite 178 series spray foam. You may be wondering exactly what spray foam insulation is and what the benefits are - allow us to explain!



The polyurethane foam is an expanding substance. It sprays on thin and expands to create an airtight barrier, which not only insulates your home, but also acts as a pest barrier. This type of foam is a 2-part foam, meaning two ingredients are sprayed together to create a chemical reaction that causes the insulation to expand and seal tightly.


What makes spray foam different from other insulation types?

 Spray foam is an incredibly high-performance insulation with an R-value of 6.7 per inch. To give you some context, the next best insulation material, cellulose, has an R-value of 3.8 per inch. The combination of these two insulations makes our hybrid system both affordable and effective. If we were to use only spray foam to achieve the desired R-value, the cost would be significantly more, and would take several more years to pay itself off. The hybrid system, on the other hand, involves a base coat of the high-performance spray foam, which is then topped off with the cellulose insulation. This system gives you the quality materials you need to take care of your home without digging too deeply into your pockets. On average, customers pay back their investment through utility bills savings within 2 years.

 Is it safe?

Spray foam is very safe for you and the environment. The blowing agent used with spray foam is certified to have zero ozone depleting qualities. This insulation also blocks moisture, which protects your home from dangerous mold growth. The material itself is non-fibrous, so it won't come apart and irritate your skin like the old fiberglass you might already have in your home.

Another added bonus you get with spray foam is that it actually asks as a structural enhancement for your home. Once the foam dries, it hardens and strengthens the beams in your home, which can help protect from storm damage.

Spray foam can be used in a variety of spaces within your home such as walls (during new construction), band sills, floors/crawlspaces, foundation walls, craw space walls, attic floors, and knee walls in the attic. It's also great for filling in odd spaces where air may be leaking. Spray foam is a superior insulation that can protect and enhance your home, while still holding up to our high standards for environmentally safe materials as it causes no damage to the ozone layer. Plus, it eventually pay for itself in utility bills savings! It's win-win all around.




What is R Value?

Published by Rease at 4:30 PM under Blog

 The term “R value” gets thrown around a lot when discussing construction, building materials, heating and cooling systems, and insulation. Everyone loves to tell you about their R Value, but if you don’t know what it means, what good is that information to you? Allow us to explain.



Quick definition

R value is a measurement of thermal resistance or heat transfer. The higher R value a building has, the more resistant it will be to heat flow. Building materials such as metal or glass have a low R value, while insulation has a much higher value.

Why should I be concerned about R Value?

As the definition states, the higher R value your home has, the more resistant it is to heat flow. Basically, a higher R value means better temperature regulation in your home and thus lower utility bills. Sadly, many builders only meet the bare minimum, so while they may try to impress you by throwing out arbitrary numbers, it’s important to recognize the difference between “standard procedure” R value and optimal R value.

How is R Value calculated?

R value is calculated based on the material. For insulation, the calculations are as follows:
Cellulose: 3.5 per inch
Fiberglass: 2.8 per inch
Rockwool: 3.2 per inch
Vermicullite: 2.7 per inch.
So, if you have 10 inches of fiberglass, you have an R value of 28.





So what’s a good R value?

The “bare minimum” R value is R 38. However, based on our experience, we have found that most homes are only working with R 15. Sadly, neither of these values are what would be considered optimal. The optimal value varies by location, but in the St. Louis area, the recommended R value for optimal performance is between R45 and R60.
Chances are your home was built with the bare minimum and has since deteriorated down to R15 or lower. By bringing your R value up to optimal performance standards, you will be enhancing your home’s ability to regulate temperature, which means much lower utility bills and a more comfortable home.

Is the Heat Wave Making You Wonder about Air Conditioner’s Efficiency?

Published by Rease at 4:13 PM under Blog

Now that summer is at its peak, it’s hard to catch a break from the heat. Many homes have rooms that never seem to get cool, no matter how low you set your thermostat. You might set your thermostat as low as 72 but never see the temperature drop below 78. Meanwhile, your AC is running continuously and driving up your utility bill costs.  There are several explanations for why this might be happening. If your home is 1 ½-2 stories, you’ve got lots of crawl space and garage area soaking up your cool air. You might also have windows that lack shading, allowing the sun to pour in and heat up your home. It’s also possible that your HVAC system is unbalanced, which results in inconsistent temperatures throughout your living space, creating hot spots that never seem to get cool.
