Foam Insulation in Charleston, South Carolina

Here are some of the many reasons we use foam insulation:

  • Air-tight sealing: With proper installation, foam insulation seals all the cracks and crevices better by getting into small openings and then expanding.
  • Energy savings: Foam insulation can reduce monthly utility bills, allows for superior control of inside temperatures and can reduce stress on your HVAC system.
  • Long-lasting: Other insulation types break down over time, but not foam insulation. It has an indefinite lifespan.
  • Protects from moisture: Foam insulation does not absorb moisture and can help reduce the potential for mold growth. This is especially important in humid climates like Charleston’s.

Not all foam insulation is of equal quality, which is why we rely one top manufacturers like Johns Manville, Demilec USA and Icynene. We also know that the experience of the installer is very important to your overall results. For the finest level of service and foam insulation products, give us a call now.
