Hybrid and Reflective Insulation Assemblies for Buildings
Materials with a low thermal emittance surface have been used for many years to create reflective insulations that reduce the rate of heat flow across building envelopes. Reflective insulation tech- nology is now being combined with other energy conserving technologies to optimize…
Reflective Insulation Assemblies for Above- Ceiling Applications
Previously published hot-box data have been used to construct equations for the thermal resistance of enclosed reflective air spaces (reflective insulation assemblies) for a wide range of temperatures, air gap dimensions, thermal emittances, and heat …
Field Evaluation of Reflective Insulation in South East Asia
The objective of this research was to obtain ther- mal performance data for reflective insulations in a South East Asia environment. Thermal resistance data (RSI, m2 · K/W) for reflective insulations are well established from 1- D steady-state tests, but thermal data for reflective insula…
Reflective Insulation for Energy Conservation in South East Asia
Thermal resistances have been measured for attic spaces insulated with reflective insulations. Three test units located in Malaysia were instrumented to provide heat flux and temperatures for the calculation of time-average RSI-values (RSI is representing R-value in SI units). The RSI for attics with …
Reflective Insulations for Hot-Humid Climates
Reflective insulation systems (RIS) are generally described as enclosed reflective air spaces. RIS provide resistance to heat flow across enclosed airspaces with low?emittance surfaces on at least one of the surfaces perpendicular …
Thermal Resistances for Reflective Airspaces at 50°F and ΔT Equal 30 °F
Enclosed reflective air spaces (reflective insulation assemblies) typically require thermal performance determinations
using a hot-box test facility. In the case of single sheet assemblies (one enclosed air space), however ….
