iFOAM is a U.S.-based insulation franchise fueled by the franchising experts at HorsePower Brands. We specialize in spray foam insulation and also provide best-in-industry blown-in solutions, insulation removal, retrofitting and other specialty project services. At iFOAM, we saw an issue with the industry—a lack of quality and trustworthy services and a clear absence of certified training when it came to spray foam. At iFOAM, we’re flipping the script by providing our certified technicians with the best tools, training and products in the trade and bolstering your experience with prompt, timely communication.

Drywall Insulation questions, answered by experts

These two types of foams are similar chemically, but they are applied in a much different way and each has its own pros and cons. Spray foam can only be used if the area where you will be installing the installation is wide open and easy to access. Injection foam should be used where it's cost-prohibitive to remove the walls that are placed over the insulation. Spray foam is a much less expensive process and requires less expertise. 

While adding insulation can be beneficial, there is too much of a good thing. Too much insulation can seal your house to the point where it can't release moisture that enters it—essentially trapping water vapor inside. Warm, humid climates are extra susceptible to mold from moisture issues, but homes in colder climates can experience condensation from an air-tight home when freezing temperatures thaw.

While you should always insulate ceilings and exterior walls, you don’t always have to insulate the interior walls of your home to maintain energy efficiency. However, there are benefits to insulating every wall, including improved soundproofing and energy efficiency throughout your home.

Water freezes at 32 degrees Fahrenheit, but the actual temperature that can cause frozen pipes can vary. Generally, it takes 12 hours for pipes to freeze at 32 degrees Fahrenheit.

Uninsulated pipes can freeze if it’s 20 degrees Fahrenheit or colder for over three hours. If your pipes are insulated, it can take six hours or longer for pipes to freeze. Note that some pipe types freeze more often than PEX pipes. Copper pipes freeze more often because the copper conducts energy and loses heat quickly.

Costs depend on the type of insulation, area to be covered, and labor, generally ranging from $1 to $4 per square foot.
