The advantage of fiber glass for maximizing energy efficiency and profits is clear - as is its potential to support profitable insulation upgrade opportunities.

That's an upgrade to which homeowners are increasingly receptive, especially with a new generation of millennial homebuyers who seem especially cognizant of energy efficiency and sustainability issues. Not to mention, fiber glass makes it easy and cost-effective to upgrade interior walls to optimize room-to-room acoustical control.

However, some builders have pointed out that the key challenge to getting homeowners fully on board and willing to pay for the upgrade is demonstrating all the benefits and payback they will enjoy - beyond sustainability. Communicating this full spectrum of tangible benefits is essential to profitable upgrades that can grow a builder's business.
