Continuous wall insulation fights off moisture and energy loss

By including continuous exterior insulation in a wall assembly, builders can deliver a better performing home.

At the 2016 International Builders' Show, Gary Parsons, lead building scientist for Dow Building Solutions Research and Development, reviewed the latest approach to wall systems incorporating continuous insulation.

"To reduce energy loss and increase occupant comfort, it is crucial for builders to consider the home as an overall system that should be insulated and sealed, especially the building enclosure," Parsons said.

He noted that rigid foam board insulation from Dow reduces energy flow through the walls by offering a complete, solid layer of insulation that covers all studs that cannot be insulated by cavity insulation.

In turn, this reduces thermal bridging, significantly improving the R-value of the wall assembly.

"Homebuilders and re-siding professionals can offer their customers enhanced energy efficiency that can help reduce air infiltration and save money," Parsons said.
