Concealed Interior Walls

Get Out of the (Convective) Loop

It’s no secret that insulation can help maximize the value of concealed interior walls. But it’s important to choose the right insulation.

Convective looping is a common phenomenon in many batt-insulated masonry walls, leading to increased potential for moisture in the wall. When batt insulation is not properly installed or if gaps are left behind the wall and the batt insulation, air near the warm side of the wall rises, air near the cool side falls ... and air convection displaces trapped air in the fibrous batts.
Insulating concealed interior walls with rigid foam insulation helps moderate the wall temperature, preventing convective looping – and improving the wall assembly’s overall effective thermal performance.
