BE5: Ladder T-walls at all exterior locations

Purpose

This method reduces the amount of framing members at the exterior wall and allows space for insulation, therefore reducing framing costs and thermal bridging.

Criteria

At interior-exterior wall intersections, the exterior wall should feature a ladder t-wall. Insulation should be installed at the exterior ladder t-wall to fill the cavity to full R-value.

Clarifications

• Consult local building codes in areas susceptible to high wind or seismic regions. 
• If installing a ladder T-wall, begin first ladder 2' above the subfloor to aid in the installation of drywall.

Confirmation

The EarthCraft Technical Advisor will visually confirm compliance of criteria during the mid-construction inspection.
