The Product

Research and forensic investigations into years of building envelope failures revealed one of the reasons for these failures was due to poor window installation details and the products used in the installation. BEC realized that the industry had introduced a flexible flange mounted window but failed to introduce an installation detail specific to the flange style of installation.  Installation practices and products used with the flanged windows and doors continued to reflect a dated “wood brickmold” style of window. It was clear that the differences between flange to brickmold must to be reflected in the installation. EnvelopeSealant TM can be utilized as part of a rain screen or face seal system.
