"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

Installing insulation helps reduce energy usage, improve home comfort, and lower utility bills by maintaining stable indoor temperatures year-round.

The R-value is a rating that measures an insulation's thermal resistance—in other words, how well it insulates. A higher R-value provides more protection for your pipes, and all pipe insulation materials should have an R-value listed on the product description or label. Each insulation type has its own R-value, which typically falls between one and five for most pipe insulation. When making a selection, Energy.gov recommends choosing a pipe wrap that is at least one inch thick, and the International Code Council (ICC) suggests choosing a material with an R-value of at least 3.

The primary reason that insulation saves you money over time is that it reduces your energy bills by making your home more energy efficient. A crucial part of an insulation system is a properly installed vapor barrier. Local building codes dictate whether your insulation requires a vapor barrier based on the type installed. While some high-quality wool insulation may not technically need a vapor barrier, most municipalities still require one to meet code.

Yes, even though frost-free and freeze-proof faucets are designed to withstand winter weather, it is still recommended to cover them with an insulated cap, especially during periods of extreme cold. These faucets work by keeping excess water inside the home's heated space and using a downward slope to drain, but this protection can be compromised. For the faucet to work correctly, you must always disconnect any attached hoses before temperatures drop below freezing, as a hose can trap water and lead to freezing. Ultimately, covering all outdoor faucets, even freeze-proof models, is the best way to prevent frozen and burst pipes.

Insulation provides additional protection for your tankless water heater. Even if the unit is installed inside the house, it’s still a good idea to wrap the unit up with insulation batts, especially if you live in cold climates. For outdoor units, you can build an insulated box around the tankless water heater for freeze protection.
