"They were very professional. Came out and gave a fair estimate. Arrived on time. Covered all surfaces not being sprayed. Sprayed generously. Nowhere was it sprayed with less than requested. Cleaned up especially well. Courteous, quick, accurate. Highly recommend them. I will use them again when I’m ready for phase three"

"All of the folks associated with this business were most informative and accommodating to questions I had before, during and after the installation. The installers are most professional; having highly experienced foam applicators and crews that are prompt to arrive and begin work. The installers ensure the customer is happy with the completed work before leaving your home/business, etc.. Finally, when the work is complete, the project site is cleaned, with all trash and debris collected and discarded by RBC. I had several bids by other company's but RBC topped them all! I highly recommend this company for your spray foam needs."

"Aaron is great to work with. I hired him originally to blow insulation in my attic then he brought to my attention that the house I just bought has a mouse problem. Lucky for me Aaron is in the process of fixing that issue for me as well. He s been great to deal with and is a very professional and kind person."

Insulation questions, answered by experts

Your home's location, budget, and the type of insulation you’re using are just a few of the factors that can help you choose the right insulation. For example, blown-in insulation is typically used in attic spaces, while batts and rolls are ideal for floors and walls. Blown-in insulation is usually a good option if you're adding more insulation to an area that already has some, but not enough.

Exposed ductwork can sweat just like ductwork placed behind walls, sometimes even more so. Ductwork sweats—like a cold drink on a hot day—because of a temperature imbalance between the air in the duct and the air in the room. In a crawl space or wall, this temperature can equalize faster due to the small space but in lofts and open rooms, that wouldn’t happen as quickly. Many people insulate their ducts for this reason.

Not necessarily. A higher R-value simply means that the insulation has a higher heat resistance and performs better in terms of how much heat passes through the material. This can be better for some homes, or it can be too high of an R-value for other homes. Again, your climate zone determines whether the insulation is better for your home.

You won’t find anything inside a cupola on a house because it’s hollow (think of an upside-down cup), allowing air to ventilate out of a roof via vents and light to come in via windows. They also usually have a base, vents around the middle (usually louvers), and a pointed cap at the top.

Yes, it is possible to have too much insulation, which can have detrimental effects. While more insulation might seem better for energy efficiency, a home needs to "breathe" or ventilate to release moisture that accumulates inside. Over-insulating can seal a house too tightly, trapping water vapor and leading to several problems, including mold, mildew, and condensation. Homes in warm, humid climates are particularly susceptible to mold, while those in colder climates can experience condensation from temperature fluctuations. Additionally, adding more insulation than the recommended amount for your climate may not provide recoverable energy savings. To avoid these issues, consult a professional insulation contractor who can determine the optimal amount of insulation for your home.
