XPS delivers high R-values in below-grade applications

A new study from the Alaska University Transportation Center, University of Alaska Fairbanks, recently reported on R-values measured on insulation removed from below-grade applications in harsh climates. This supplements data from two previous similar research projects. All the three studies reported the in-service R-values per inch of extruded polystyrene (XPS) and expanded polystyrene (EPS) insulation installed under roads and airport runways with the time in-service ranging from one to 31 years.

Specifying metal rainscreen assemblies

Metal can be formed into several shapes, sizes, colors, and textures to meet almost any aesthetic. If specified correctly, the assembly will last for the life of the building with very few issues. Three broad categories—composites, insulated metal panels (IMPs), and single-skin—of metal rainscreens are widely used.
