Insul Kings is a fully licensed and insured weatherization contractor specializing in weatherization work (adding insulation to home), energy audits, whole house air-sealing, and the installation of various types of insulation for both commercial and residential projects. We are a proud partner of Mass Save & NH Save and are rated in the top 5% of their contractor scoring.

"Insul-Kings is wonderful to work with. They called in the morning to narrow the arrival time, which is very considerate. Nate and his crew arrived on time and CRANKED like a well oiled machine. I have a 4' crawl space. You can barely crouch. No problem! That's why God invented knee pads. They foamed and installed the insulation like it was their own home. It was a work of art. and came out better than I imagined. They patiently indulged my "old man" inquisitiveness. The crew represented Insul-Kings very well. I highly recommend them. This was done through the Mass Save program. So the $2100 job only cost me about $500.00"

"After Fernando removed old flooring, he found hard-to-remove glue on the subfloor. He took time to carefully remove the old glue using a hot gun. Everything he did was done thoughtfully and meticulously. After new flooring was installed, he choose to return to improve one detail, so everything would be done perfectly. Fernando is honest and pleasure to deal with. I highly recommend him."

"Highly recommend Express Roofing! Mike and Nick were always very responsive and answered all of my questions. Felix and his crew did an outstanding and high-quality job on the roof and the cleanup. The estimate was significantly lower than the others I received, and even though we had a lot of plywood to replace, the final cost was still lower than the others! Have already recommended them to family members."

"This is the second time we hired Mike. Our projects were having our fieldstone basement repointed, adding a small piece to our existing fence to our garage, and adding paving stones behind the garage. While he was here, we showed him another project we were considering, and he was able to fit that in the following week. The second project was cleaning out the attic of the garage, removing the floorboards and installing a new 4-foot shelf in the attic ceiling, painting the interior, and installing 3 new windows. Mike is truly a jack of all trades! All the projects above came out great and we were very thankful to have his guidance as things went along. He provided a quote for the job, was communicative, and arrived in a timely manner. He cleaned up after very well after each day and he explains his process, problems, and solutions as he goes so, I always felt informed of what was going on. I would definitely recommend and hire Mike again for future jobs."

Insulation questions, answered by experts

We recommend that you cut batts of fiberglass insulation with a sharp utility knife. However, in a pinch, you can use tools such as a box cutter or even a pair of scissors. No matter what cutting tool you use, just make sure it’s sharp so you get a clean, straight cut. Always cut along the back (foil) side of the fiberglass, rather than the “fuzzy” side of the material.

While the ideal temperature for your garage is partially based on your preferences for a comfortable garage space, you'll still want to maintain a temperature between 40 degrees and 68 degrees Fahrenheit to protect your belongings and vehicles. If you are unable to maintain temperatures that fall within this range, then you may want to consider installing a heater in your garage to prevent temperatures from dropping below 40 degrees.

Whether you should remove old insulation before blowing in new insulation depends on your particular situation. Fiberglass insulation attracts insects and mold over time, so if it has been decades since your last insulation upgrade, consider removing the old materials before placing the new ones. However, most types resist mold, insects, and mildew, so once you get the go-ahead from your contractor that your space is free from all three, feel free to install the new insulation directly on top of the pre-existing materials.

Polyisocyanurate foam, or polyiso for short, has the highest R-value per square inch: 6.5 to 6.8. Polyiso is a rigid foam that comes with a reflective foil on both sides to serve as a radiant barrier. Given its high R-value, rigid foam is usually meant for foundations and basement walls.

The type of insulation you need in your home depends on your location, the installation site, and your region’s climate. According to Energy Star, insulation in homes in the Southern United States should have an R-value of between R30 and R60 in attics and R13 to R25 in the floors and walls; homes in moderate climates require R values of R38 to R60 in attics and R25 to R30 in floors and walls; and homes in northern states require an R value of R49 to R60 in attics and R25 to R30 in floors and walls.
