Resilient channel has been on the market for more than 50 years, but it seems not everyone has a clear idea of when it can be used to solve sound transmission issues in wall and floor/ceiling assemblies.
Construction is underway on the Hilton Garden Inn, a 12-story high-rise on the University of Iowa campus. The team working on this 5110-m2 (55,000-sf) steel-framed hotel—including Cities Edge Architects and contractor Rushton Sheet Metal—has found a strong solution to the project’s variety of insulation-related challenges.
Increasing emphasis on sustainability and energy efficiency has had a huge impact on the construction industry. Materials manufacturers scrambled to develop products that would allow builders to meet and exceed the new codes.
The roof assembly is an important aspect in achieving energy code compliance because it often accounts for a large portion of the building envelope. It becomes even more critical in single-story non-residential projects such as manufacturing plants, warehouses, distribution centers, retail stores, and offices.
Plastic foams for thermal insulation have been available for more than 70 years. Extruded polystyrene (XPS) was introduced in 1943, followed by expanded polystyrene (EPS) in 1950, and polyisocyanurate (polyiso) in 1954.
