FAQ's

Spray Foam is available in two kinds: open-cell foam and closed-cell. The cost of this kind varies based upon several factors, including what kind of cell foam you use, the size of the area that needs insulation, the R-value (thermal resistance), your location, weather, the cost of labor in your area and whether it's a new or existing home.

Closed-cell is more expensive than open-cell foam due to its higher R-value. (R-value is the measure of an insulation's ability to resist heat flow). But the average cost is between $3 and $5 or could be higher than $7 per square foot. For an accurate estimate, it is recommended to contact a spray foam insulation contractor near your area.

Many homeowners are unsure about when to apply spray foam. It is best to apply spray foam during the warmer months when the temperature is above freezing. This will allow the foam to expand properly and cure properly. Typically, the installation should be done after other building materials, such as wiring or heating/cooling ducts. This means that it should be added to your home's construction process during its final stages.

It's important to ensure the surfaces you plan to insulate are clean and dry before you begin. You can ensure that your foam insulation is installed correctly and provides optimal performance by taking these factors into account.

Spray foam insulation application by yourself can be hazardous. The chemicals in the spray foam can be dangerous if inhaled, and the fumes can irritate the skin and eyes. In addition, if the spray foam is not applied properly, it can cause gaps and cracks in the walls that will allow heat and cold air to escape.

This is why it's important to hire a professional contractor with the experience and expertise necessary to make sure that the insulation is applied correctly. They will have the necessary safety equipment that makes the job easier and produce better results.

Manufacturer warranties for spray foam insulation can vary widely. But most warranties last for at least ten years. Some insulation companies offer a lifetime warranty on their spray foam application. But in general, most manufacturers offer a limited warranty covering defects in materials and workmanship.

However, spray foam is known for its durability. With proper maintenance, your spray foam insulation should last for decades to come. When shopping for spray foam insulation, be sure to ask about the warranty to ensure both product and workmanship meets your needs.

Corrosion under insulation (CUI) is a form of hidden damage that can occur when moisture gets trapped underneath insulation materials and starts to react with the metal surfaces underneath. This is more common in industrial or commercial settings where pipes or tanks are insulated, especially in humid or wet environments.

While spray foam insulation is less likely to cause CUI compared to traditional materials, it's still important to install it properly—especially in areas prone to moisture. At Super Foam USA, we use closed-cell foam for better moisture resistance and apply insulation with strict attention to sealing and ventilation, helping prevent long-term structural damage.
