Home Insulation

Update your home insulation and save big

Stop losing heat—and money—by upgrading your home’s insulation. Get up to $1,400 in rebates when you use a contractor for installation.

The benefits of insulation

  • Reduced heat loss
  • A cost-effective way to lower your energy bills
  • Ensures home safety—in addition to installing insulation, contractors check your energy systems to make sure they’re working properly
  • Improved home durability, by keeping outside elements out and reducing moisture
