F.A.Q.

Q. How long will the process take?


A. Most homes take 2 days from start to finish. Some homes may be completed in only1 day, and some larger 2 story homes may take 3-4 days.

 

 

 

Q. Are you and your crew licensed and insured?


A. Yes! Affordable Foam Insulation is a licensed contractor with the state of Iowa (license number C121786) and is fully insurance through IMT with $1,000,000 policy (insurance proof available upon request).

 

 

 

Q. What is spray foam?


A. Spray foam is a spray-on insulation product that has increasingly become very popular in recent years, although it has been used in construction since 1979. It is a two part product that is actually manufactured at each job site. Parts A and B are pumped from 55 gallon barrels and come together at the tip of a special spray gun and then compressed air sprays the product onto the surface. The products then chemically react to create the spray foam insulation. The reaction causes the spray foam to rapidly expand and set up.

 

What is the difference between open and closed cell spray foam?
There are two main types of spray foam—Open cell and closed cell. Open cell spray foam expanding more (about 120-140 times its original size) whereas closed cell spray foam expands less (about 40 times it original size). Open cell, since it expands more, is softer, more flexible and has lower R-value per inch (about 3.7 R-value) than closed cell. Closed cell spray foam is more dense, rigid and hard, and therefore has a higher R-value per inch (about 6.9 R-value).

 

 

 

Q. Which is better, open-cell or closed-cell spray foam?


A. Both are excellent insulators and both are much better than the old-fashioned fiberglass and cellulose insulation. Open-cell spray foam more economical than close-cell spray foam. Closed-cell spray foam had some benefits that open-cell does not. Closed-cell becomes a vapor barrier and moisture barrier when sprayed on 2” thick. In areas where moisture is a concern such as basements, crawlspaces, metal buildings, etc. then closed-cell spray foam is preferred. Also since closed-cell spray foam is very rigid, then in areas where the insulation is going to be left open and not covered up then closed-cell would be recommended.

 

 

 

Q. Does it provide sound proofing?


A. Yes! Foam insulation absorbs sound quite effectively. Our foam is rated to absorb 40 - 50 decibels of sound. Most homeowners immediately notice a sound difference from the first day of being installed.

 

 

 

Q. What if I already have insulation?


A. It is very common for homeowners with existing insulation to have our high R-value foam insulation installed. If your home is 50 years old with the original insulation you could benefit greatly with our foam insulation.

 

 

 

Q. What is the R-value of spray foam?


A. First let me say that many people mistakenly think that R-value measures the energy efficiency and that is not accurate. R-value measures the amount of thermal transfer of insulation. While that is great in a laboratory setting it does not exactly translate to the real world where air infiltration plays a major role in the effectiveness of insulation. Spray foam will totally eliminate or drastically reduce air infiltration in wall cavities making it much more energy efficient than fiberglass or cellulose. Also many people think that the R-value on the packaging of batt insulation is the real R-value they are getting when studies have show that between packing, shipping and improper installation the true average installed R-value is about 28% less than the packing label. Whereas as spray foam insulation is manufactured right there at every jobsite so you can be assured the R-value of spray foam is accurate.

 

With all that being said the R-value of open cell spray foam is around 3.8 per inch and around 6.9 per inch for closed cell spray foam.

 

 

 

Q. Why should I use spray foam?


A. Spray foam will pay you back every month with much lower utility bills plus make your house much more comfortable than using fiberglass or cellulose insulation. Spray foam is an excellent choice for insulation crawlspaces and rim joists too.

 

 

 

Q. Is spray foam a good option for new construction?


A. Let’s say you are building a new house and are trying to decide between the cheap old fashion batt insulation or investing in spray foam. You see R-value of 19 for batt insulation and R-21 for open cell spray foam. If you just look at that then you may think spray foam may not be worth the extra investment. But remember that the true R-value of batt insulation can be 28% less than the label plus batt insulation does little to prevent air infiltration. The spray foam may costs $3000 more. And unfortunately if you are not properly educated about R-values and air infiltration you may wonder if the extra money for spray foam it worth it. The extra $3000 for spray would add about $15 to the house payment. So then the big question is: Will spray foam save you more that $15 per month in utility bills than batt insulation? If you think the answer is Yes (and that is the correct answer by the way) then you would be foolish not to invest in spray foam. Plus spray foam will stop drafts and air leaks making your house much more comfortable making it a very smart investment.

 

 

 

Q. Are there any fumes/odors/toxins? Is it pet safe? Environmentally safe?


A. Our foam is environmentally safe with no fumes or off-odors or toxins. You, your pets and babies are safe to be home while we are installing our foam insulation.

 

 

 

Q. Will your foam insulation blow out my walls?


A. Affordable Foam Insulation uses a very unique completely non-expanding foam insulation. Our foam does not expand while inside your walls so it will not blow out walls.
