The Key to Unlocking Door Performance

While significant time and effort are often put into specifying and reviewing the design and performance of window products on projects, the weatherproofing performance of doors is often overlooked. When designing and installing doors, it can be challenging to balance competing requirements for weatherproofing performance, operability, Americans with Disabilities Act (ADA) compliance, cost, and interior floor finishes. This article surveys various types of doors, how and where they are installed on buildings, and the weatherproofing performance anticipated for each door type and condition. We also discuss flashing and installation challenges related to specific door types and architectural applications.
