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).
