About the IGSDB Database

The IGSDB is a database of thermal and optical properties for glazing and shading products. The glazing product data is measured in a spectrophotometer and submitted by manufacturers. The shading product data is currently measured at LBNL.

See the LBNL website for information about glazing product data (IGDB: https://windows.lbl.gov/software/igdb) and shading product data (CGDB: https://windows.lbl.gov/software/cgdb)

Lawrence Berkeley National Laboratory (LBNL) maintains and publishes the IGSDB. The U.S. Department of Energy (DOE) provides support for the optical laboratory, participation in standards activities and related research. This work was supported by the Assistant Secretary for Energy Efficiency and Renewable Energy, Office of Building Technology, State and Community Programs of the U.S. Department of Energy, under Contract No. DE-AC03-76SF00098.
