Wall Heat-Loss Cross-Section: Temperature Profile Through Insulation

This is a 2D to-scale cross-section view of the same multi-layer wall as the 3D house model: gypsum board, your chosen insulation, and a brick veneer, whose combined thermal resistance sets a live U-value, heat-loss power for a 100 m² wall, and a rough heating-season cost. Instead of an isometric house, this view plots the wall's actual temperature profile — the real, physically-derived temperature drop across each layer under steady-state conduction — directly beneath a pannable, zoomable cross-section, with animated particles showing heat physically crossing from warm indoor air to the cold outside.
