Floor Assembly Layers
Add layers from exterior (underside) to interior (floor surface)
Include air films (exterior & interior surface resistance)
Apply effective R calculation (thermal bridging via studs)
NBC 9.36.2.4
%
From Table A-9.36.2.4.(1)-A.
A checkbox will appear under each insulation layer — tick it to apply the parallel-path correction (cavity + framing) for that layer.
Assembly type + spacing auto-fill the framing factor from BCBC Table A-9.36.2.4.(1)-A. Rim joists are excluded from this table per Note (1) — set FF manually (typically joist thickness ÷ spacing, e.g. 38/400 = 9.5%).
