- Abstract
- Thermal resistance measurements of a well-insulated residential wall are conducted using a calibrated hot box operated under a range of winter and summer climatic conditions. The wall consists of two insulated wood-frame sections with staggered framing. The measured thermal resistance is examined as a function of mean wall temperature and compared with predictions using the ASHRAE parallel-path method, the ASHRAE isothermal-plane method, and a temperature-dependent thermal conductivity finite-difference model. The effects of the compression of glass-fiber blanket insulation and nail penetrations on the overall thermal resistance are investigated.
