Wall Sections

Build a wall assembly layer by layer and check its R-value against the energy code.

• Wall Sections overviewBuild a wall or floor assembly layer by layer, see it drawn to scale, and check its R-value, dew point and code path.
• Layers and materialsAdd materials from the library, set each layer's thickness, fill stud bays, and put the layers in order from outside to inside.
• R-values and U-factorWhat the Thermal panel's rated and effective R-values mean, and which one the code check counts.
• Code checkHow Wall Sections checks an assembly against the IECC prescriptive paths for its climate zone, wall type and code edition.
• Dew point and vaporCheck where condensation could form in the wall in winter or summer, and whether the interior vapor retarder fits the climate zone.
• The section drawingRead the to-scale section, switch between color and black-and-white, and show or hide the dew point overlay.
• Export and printSave the assembly as a file, or export the section as a PDF, PNG or SVG with its numbers and caveats on it.
