ASTM’s Committee C24 on Building Seals and Sealants is currently developing a guide that will be used internationally in order to assist designers and consumers in choosing the most suitable aerosol foam sealants for projects. The standard would distinguish between sealants based on the areas in which they would be used, namely: windows, doors and skylights, where they would be applied as a secondary seal, fire blocking and gap sealing, and adhesive foams used as drywall or subfloor adhesives and for structurally insulated panels and insulated concrete forms.
The organization says that its new standard would help designers and consumers to understand the wide variety of foam sealants currently available on the market allowing them to make better material choices. The guide will also highlight the energy cost savings that can be achieved through the use of aerosol foams. An easily understandable format using pictograms will demonstrate the ways in which foam sealants can be used. Different types of dispensing mechanisms, and typical can sizes will be explained. The subcommittee is inviting expert input related to foam sealants’ movement capability and its measurement.
