Among the many energy drains, heating and air conditioning are two of the most resource-intensive activities that will test the performance of a building’s envelope (roof, walls, and windows). To prioritize thermal performance, specifiers are putting high-performance building materials to work, including polyisocyanurate (polyiso) insulation.

Indoor atriums tend to feature many sound-reflective material surfaces, creating a risk of excessive build-up of speech and activity noise. While the dialogue among activity noise, spatial volume, and material reflectivity tends to pose acoustical challenges, it is entirely possible to seamlessly incorporate effective acoustical solutions into the design...
