Compute thermal resistance R = d over k from material thickness and thermal conductivity, for wall and roof insulation design.
输入材料厚度 d 与导热系数 k,求热阻 R。
| Item | Formula / Note | Source / Standard |
|---|---|---|
| Thermal resistance | R = L/k | ISO 6946 |
| Units | m²·K/W; higher R = better insulation | ASHRAE Handbook of Fundamentals |
