Spray Foam Insulation Tax Rebates


  • We love the spray foam you did for our home. Added 900 square ft, you put 6" foam in our roof 3 years ago over the upstairs addition. Our energy bills didn't go up a penny- just shows how much heat we were losing in the winter and letting in the attic in the summer. Great investment!
    - Ernie, Jackson TN

  • I have seen the Spray Foam system before, but only in the home improvement shows on TV. I was introduced to Apex by my contractor, and was convinced to try it. Couldn't be happier! Great return on investment.
    - Mike, Nashville TN

  • I was in my house built in 1948 for 3 winters, each year I would add more fiberglass insulation to the floors in my crawl space. My home was never warm until I tried spray foam. Not only is the house warmer, but it has saved me money on the energy bill.
    - Michael, Nashville TN

  • Apex Building Company provided whole house residential spray foam insulation for my new home. They did an excellent professional job. I would recommend them for any insulation job of any size!
    - George, Jackson TN

  • I hired this company to spray insulation into my newly built steel construction home. They came in and did a very professional job enclosing the entire shell with open cell foam, sealing every conceivable leak. I have been very please with the results and ascribe my low utility bills to it!
    - Pete, Memphis TN

  • Apex was very professional and knew about the product they were selling. I talked to several spray foam contractors and none of them were as knowledgeable as Michael at Apex. They cleaned up well and made sure things were done to suit me. I Highly Recommend them for anything spray foam or insulation!

Fiberglass Spray Foam Insulation (JM SPIDER)


Johns Manville Spider® Custom Insulation comes in variable thickness levels can fill 2x4 cavities up to an R-15 thermal rating, 2x6 cavities up to R-23, and six-inch steel stud cavities up to R-25. JM Spider® insulation also reduces sound transmission, achieving a Sound Transmission Class of 43 in a standard 2x4 wood-framed wall.

JM Spider® insulation resists mold because it sprays in almost dry and is treated with a U.S. EPA-registered mold inhibitor to protect the insulation against mold. JM Spider® insulation can be used for both wall and ceiling applications. In addition, only fiber glass insulation made without formaldehyde—such as JM Spider® Custom Insulation—can pass Environmental Specification 1350, the toughest indoor air quality test in North America, with a non-detect for formaldehyde.

SPIDER Insulation is very good at fitting around items in walls like pipes and wiring, leaving no air pockets that can reduce the overall efficiency of the wall. Dense pack SPIDER produced by Johns Manville can seal walls from air infiltration while providing the density to limit convection, when installed properly. It is made of recycled glass content with a clean, white appearance and uniform texture. Unlike dense pack cellulose, SPIDER applies with less moisture than the wood framing in homes, dries fast for quick sheetrock installation with no concerns of moisture and guarantees not to sag over time.

Home energy savings on utility bills depending on the existing
