Company History

Formed in 1994, by Mr. John Wheaton, P.E., LEED AP, President, and Mr. Richard Sprague, Vice President, Wheaton Sprague Building Envelope (WS) is a professional services company with a staff of designers, consultants, engineers, and LEED AP’s, with technical focus on building facades, building envelopes, and custom and standard curtain wall systems. WS is organized into Building Envelope Engineering (BEE) and Building Envelope Consulting (BEC) Divisions, providing a full array of expert services to the building envelope industry in one enterprise, with experienced professionals and multiple offices.

WS Building Envelope experienced growth primarily by providing services for clients on many projects through our Building Envelope Engineering Division. Throughout our history, we provided consulting services as part of our practice. However, there was not a legitmate manager to devote attention to growing demand and interests, and to drive that business’s unique client needs and technical specialties. In response to our desire to be a complete building envelope specialty company, in 2008 the Building Envelope Consulting (BEC) Division was added, and Mr. Mark Coulis, LEED AP, was appointed Vice President of the Division. Mr. Coulis is a highly qualified senior design consultant operating from the Stow, Ohio office, with a distinguished career in the building envelope consulting field.

As part of the ongoing strategic plan to add branch offices to support our growing service offerings, WS added a Bloomington, MN branch in 2010, and a pending Raleigh, NC branch in 2012. WS Building Envelope will continue to provide national and regional clients with pragmatic, value-oriented solutions through branch offices, in both the consulting and engineering divisions, utilizing specialized technical expertise to aid in the design and construction of building envelope systems.
