"We are so glad we found Bo's Insulation. We are very pleased with the job they completed today on our attic insulation. From salesman Nyc to the installers James and Abe and office coordinator Sydney everyone was polite, professional and very knowledgeable. They attend classes on insulation, sealing and energy efficiency and it shows in their work. They walked us through the OG&E Rebate. We highly recommend Bo's Insulation. Here's to saving on our gas and electric bills!"

"The project went well. The ladder install made a big mess but all was cleaned up. Decking install was good but area had to be reduced due to obstacles but still turned out to be plenty. Insulation was blown in and that also went well. I had some low gable vents that leaked the insulation that was blown up to them. I don’t think this could have been avoided, but that leakage blew back inside the back door and made a mess in the laundry room and kitchen. They offered to come back and clean this up but I went ahead and did the cleanup myself so it didn’t get tracked throughout the house. All things considered, I am very pleased with the job they did."

"I needed more insulation in the attic. I could tell when Jessie came by to give me an estimate that he was very knowledgeable and knew exactly how and where the insulation needed to go to give the best coverage. The crew came by today and installed the insulation. I had looked at pictures Jessie took when he gave the estimate and then I saw the pictures after they finished and could tell they did an outstanding job using the tenting method to better cover the plumbing. Of course I had to climb up into the attic and get a closer look and I can tell you I am really happy with what the Weatherization Experts did."

"My installer was very knowledgeable and professional. His team promptly installed the insulation and baffles, as I requested, and tried to clean up afterward. I was already sweeping the garage, so I declined. The cost was exactly as quoted. Would be nice if they made it an option to pay online. (Maybe thatâ s possible now.) There was an immediate improvement in the comfort in the home. I would highly recommend this company."

Insulation FAQs, answered by experts

R-30 insulation is better for higher thermal resistance, but whether it’s "better" depends on the application. R-30 is much thicker and suited for areas like attics or floors in cold climates, where more insulation is required. R-13, on the other hand, is thinner and works well for 2x4 walls or milder climates where less insulation is sufficient. Choosing between R-13 and R-30 depends on the area being insulated and the climate. For example, R-30 provides more insulation but may not fit everywhere in your home.

Three signs that you need crawl space insulation are drafts, high energy bills, and mold. Drafts can start in crawl spaces and cause hot or cold air to spread to the rest of your home through holes in the floors and walls. And even if your entire home is well-insulated, you can still feel an unchecked draft from your crawl space and in your utility bill. Uninsulated crawl spaces can let in air and moisture, and because they’re built directly on the ground and difficult to dry out, they are hotspots for mold and mildew.

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 time required for insulation installation can range from a few hours to a few days, with most projects taking 1-3 days to complete. The final duration depends on the project's size and complexity, the area size, and the type of insulation being installed.

Vapor barriers in attics are a bit outdated and most areas no longer recommend them for attic spaces. For vented attics, the best method is usually to install drywall and cover it with latex paint before attaching insulation fiberglass, cellulose, or foam insulation. When renovating an attic to use as a living space, a contractor can guide you on the best way to cover insulation.
