"Tony was one of three bids we took on encapsulation our crawl space we built our house in 1997 the codes were different then than they are now. I had many questions he answered them all with good explanation made sense to me to go with the spray foam versus other types of encapsulation systems. It was the right price point he gave several different options that we could choose from. I would recommend him without hesitation."

"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."

Insulation questions, answered by experts

You should not use spray foam insulation in several specific areas. Avoid applying it in spaces exposed to high temperatures, such as near electrical boxes or recessed lighting, unless the foam is specifically rated for such use. Applying foam near electrical boxes can damage the wiring, and using it too close to lightboxes or recessed lights creates a potential fire hazard. Additionally, do not use spray foam in areas prone to shifting or movement, as this can lead to cracks and gaps in the insulation. Finally, open-cell foam is unsuitable for use below ground or in areas exposed to moisture because it can absorb water, which compromises its insulating effectiveness.

It is normal for the attic to be hotter than the rest of the house in the summer, but only by about 10 or 20 degrees. Attics that aren’t properly insulated or ventilated can reach temperatures of 130 degrees or more which can cause damage to the home’s structure, including the roof, wood framing, and HVAC system.

The life span of insulation is between 20 and 100 years. At that time, existing insulation can fall victim to gravity, resulting in compression, which reduces its insulating protection or R-value. If you can't simply add more insulation over the existing material, removing the old to increase the effectiveness of the new can reduce your energy bills and make the project worth the time and money investment.

You do not need to drywall over most types of garage insulation. However, doing so can increase noise reduction, make the space more attractive, and keep children and pets from touching harmful fiberglass insulation. If you’re using cellulose or some other type of blown-in insulation (fiberglass and mineral wool are common), you will need drywall to contain the insulation material.

Insulating your home's exterior walls can realize up to a 20% reduction in your monthly energy bills. This means that regardless of how much the project costs, it can begin to pay you back immediately. Additionally, adding spray foam and other high-end materials can increase the selling value of the property.
