Building Envelope Design, as the skin of the building, is the first line of defense against the exterior weather elements. The building envelope requires the most design, construction, and attention to detail of any part of the building. Even when designed and constructed properly, the building envelope requires continuous evaluation and maintenance to keep the elements out. Like a screen door on a submarine, ignoring the building envelope is a recipe for disaster.

At TF+E we pride ourselves on meticulous attention to detail and making sure that our design and details are easy for the construction team to understand so that proper installation by the contractor is more likely. Our design service is informed by our experience with the investigation of building envelope failures where others did not properly design and/or construct the building envelope.

If your building envelope fails, please call us to assist with the evaluation and to develop repair plans, details, specifications, and a budget for the upgrade or repairs.
