Both fiberglass and stone wool insulation have merit, promote fire protection and sustainability, and offer value to architects, contractors, and property owners alike. This article’s intent is to present a scientific examination of the benefits of using each, in particular with respect to meeting fire and acoustic requirements and codes.
A well-insulated building envelope is the starting point in any energy conservation strategy. The embodied global warming potential (GWP) of the insulating material, as part of a complete wall assembly, must be weighed against the use-phase energy efficiency contribution to see the complete environmental picture.
Today’s high-performance building market is driven by increasingly stringent energy codes and a growing demand for greater building efficiency, sustainability, and affordability—meaning specifying and building masonry cavity walls and adhered masonry walls with materials that work together as a functioning system is more critical than ever.
Exterior insulation and finish systems (EIFS) are proprietary wall cladding assemblies that combine rigid insulation board with a water-resistant exterior coating. Popular chiefly for their low cost and high insulating values, they are used on a range of construction types, from hotels to offices to homes.
In the November 2015 issue of The Construction Specifier, this author examined the basics surrounding building material disclosure and environmental product declarations (EPDs). In this followup article, he looks at how the information will be used in lifecycle databases, whole-building analyses, product manufacturer improvement, green project rating systems, and building codes.
