Question 1

What is thermal resistance?

Accepted Answer

Thermal resistance (R-value) measures insulation effectiveness - higher values mean better insulation. R-13 is standard wall insulation.

Question 2

How are thermal properties related?

Accepted Answer

Thermal conductivity (k) and resistance (R) are inverses: R = thickness/k. Specific heat determines heat storage, while conductivity determines transfer rate.

Question 3

What are typical R-values?

Accepted Answer

Single-pane window: R-1, insulated wall: R-13 to R-21, attic insulation: R-30 to R-60. Higher R-values provide better insulation and energy savings.

Question 4

Why convert thermal units?

Accepted Answer

US uses BTU/hr·ft²·°F (U-value) and R-value, while metric uses W/m²·K and RSI. Converting is essential for international projects and specifications.
