Assembly Library
The Assembly Library holds your reusable building-assembly templates — walls, roofs, floors, foundations, and more — each built as an ordered stack of material layers. Define a high-performance wall or roof once, and TrueGrade calculates its total R-value from the layers and expands it into a full bill of materials whenever you apply it to a project. It is the engineering counterpart to the Materials Library: materials are the parts, assemblies are the details you build from them.
Who Uses This
The Assembly Library is available to Admin, Project Manager, and Senior Estimator roles (and Platform Admin) — the people building the details that drive estimates and procurement.
Where to Find It
Assemblies sits under the Library group in the left navigation sidebar.
Building and Using an Assembly
Create the assembly
Click New Assembly and give it a name and an assembly type — Exterior Wall, Interior Wall, Roof, Floor, Foundation, Window Install, Door Install, Slab, or Other. Optionally add a description, mark it PHIUS-compliant, and record a WUFI assembly name for energy-model cross-reference.
Add layers in order
Add each layer of the assembly from the exterior in, drawing materials from the Materials Library. For each layer, set the thickness, the quantity unit (square feet, linear feet, each, board feet, or cubic feet), the quantity per square foot of assembly, and a waste factor (defaults to 1.1, or 10% waste).
Let TrueGrade calculate the R-value
As you add or remove layers, the assembly’s total R-value recalculates automatically from each layer’s material and thickness — no manual tally.
Apply the assembly to a project
Assign an assembly to a project and enter the area it covers (for example, 1,200 square feet of wall). One assembly can be reused across many projects.
Expand the bill of materials
Expand a project assembly to generate its bill of materials. TrueGrade multiplies each layer’s quantity per square foot by the area, applies the waste factor to get gross quantity, and pulls unit costs from the Materials Library to produce a per-material total cost.
Build assembly templates for your most common passive-house wall, roof, and foundation details. Once your standard details live in the library, expanding a new project’s material takeoff becomes a matter of entering areas.
