This article explores some of the benefits realized through the speed of construction enabled by specifying insulating concrete forms (ICFs)—a technology that combines reinforced concrete with thermal insulation. The piece profiles diverse projects—a school, a multi-family midrise, a big box, and a hotel—in detailing the cost efficiencies. It also looks at ICF design possibilities, installation techniques, and accessory products.

Masonry materials and wall systems, with their inherent thermal mass characteristics, provide designers with many options to achieve energy-efficient designs. This article illustrates examples of wall configurations that exceed national building code requirements and high-performance standards, taking into account factors like increased R-values for non-mass opaque walls (prescriptive design), continuous insulation, requirements for R-value reductions caused by thermal bridging, mandatory continuous air barriers, and options for building energy design.

In the October 2014 issue of The Construction Specifier, an article examined how urban lumber harvesting has emerged as an option for resources otherwise devastated by the emerald ash borer. It takes a particular look at how Milwaukee, Wisconsin, is becoming an important player in finding new opportunities for wood—carpentry, casework, and flooring included. This web piece takes the story further.

Sound Thoughts on Door and Frame Assemblies: Exploring differences between STC and STL ratings

When sound control acoustic door assemblies are selected, the usual way is to specify a sound transmission coefficient (STC) rating in accordance with established standards. However, this is not as catch-all as it sounds, especially when the sounds that must be blocked come in different frequencies. This article works to clarify some misconceptions about STC, and explores sound transmission loss (STL), which is derived from actual lab testing at specific frequencies.
