About Building Envelope Technology & Research

Building Envelope Technology & Research (BET&R) is a professional, full service building envelope consulting firm, dedicated to bringing our knowledge and expertise in building envelope science to the practical world of commercial, industrial, and residential construction.


BET&R was founded in 1997 by Principal Consultant and Technical Director Jim Carlson in response to a growing need for a quality and detail-oriented full service building envelope consulting firm capable of providing its clients with practical, real-world solutions drawn from advanced knowledge in the fields of roofing, waterproofing, and cladding science. Over the past decade, the firm has grown to include experts in architecture, LEED design, infrared thermography, and BET&R has been engaged as the primary consultant on projects throughout the continental US, as well as in Alaska and Hawaii.


While BET&R has grown rapidly through word of mouth and the demand for the type of high-quality services we provide, the firm has remained a dedicated and active part of the local community, providing support for local programs through donations of time, services, and money. BET&R has also retained our dedication to employing the best professionals in the field, and to ongoing training and education for each member of our technical and administrative staff.


BET&R is a proud business member of the greater Pacific Northwest, and maintains a corporate giving program to support the regional and local communities. BET&R is able to offer discounts to qualifying industry associations (please call for details).
