Understanding how walls stop heat loss—and how to measure it
This book explains a practical method for evaluating heat transfer through building walls in a controlled, repeatable way. It covers the main factors that affect heat flow, including surface resistance, the wall material, and the role of air and radiation in cavities.
It presents a clear framework for analyzing different wall types, describes an experimental instrument, and shares results from what is tested on common wall constructions. The discussion helps readers estimate how changes in temperature and materials influence overall insulation, with concrete data and observations.
- How heat moves through walls and why surface resistance matters
- How air spaces, radiation, and convection impact insulation
- How to estimate wall conductance and resistance using practical measurements
- What factors most affect the insulating value in common wall types
Ideal for readers of building science, civil engineering, or architectural technology who want a practical, data‑driven view of wall heat transfer and insulation design.
