Abstract

In late 1990, the National Research Council of Canada (NRC-CNRC) and the Canadian Construction Materials Centre of Canada (CCMC) set about developing a durability protocol for aerosol foam sealants. Major input for this effort was supplied by Dr. Mark Bomberg then on the NRC-CNRC staff. At that time a major manufacturer of aerosol foam sealant wished to address some developing concerns whether foam sealant used around the perimeter of windows and doors during their installation was really durable. The manufacturer completed the durability testing according to the established NRC protocol. Now the protocol is also part of a new Standard CAN/ULC-S710.1 and CAN/ULC-S711.1. This paper will describe that testing as it was completed at the third party laboratory, Air-Ins Inc., of Montreal, Canada using criteria from the 1995 National Building Code of Canada [1]. The data obtained also formed the basis for CCMC Evaluation report 13074-R [2].
