RE3: Energy heel truss system or raised top plates for all vented, unconditioned attics

Purpose

Raised heel, energy trusses extend further past the wall and are deeper at the wall, thus allowing room for full insulation coverage over the top plate of the exterior walls.

Criteria

Install energy heel trusses or raised top plates to ensure full depth of attic insulation above exterior wall top plates. Depth of insulation above top plate may be traded to R-21 when allowed by code.

Confirmation

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