Proper sealant joint design and installation around the perimeter of a door frame is also essential to the building’s waterproofing. The frame’s perimeter must be integrated into the wall’s water-resistive barrier (WRB) through flexible flashings, or water will migrate around the outside of the door. Other leak risks are discussed in the following paragraphs. It may seem obvious, but a door left open, or one that cannot be closed tightly because of wear and tear, is a significant problem during a storm. There are many potential pathways for water to leak in through a door, but the biggest opening is, of course, the doorway itself. Fowler, PhD, PE-the faculty advisor for the research being performed at the Durability Lab, a testing center at the University of Texas at Austin.) Common leak paths for doors. However, these doors’ sill tracks and higher allowed thresholds can provide enough of a step to prevent water entry, so they are not covered in detail in this article.) (The authors gratefully acknowledge the continuing support and leadership of David W. (Many of the leak sources outlined in this article would also apply to sliding glass doors. This article focuses on accessible exterior swing doors used on office buildings, retail, multi-family residential, and institutional buildings for entrances, emergency exits, terraces, balconies, and patios. Most of the sources of leaks can be eliminated by better design and construction practices, but there remains an intractable problem that must be addressed by the industry. Nevertheless, they continually struggle to prevent water infiltration through this fundamental building element.įigure 1 catalogs the various routes taken by rain infiltrating a doorway. Designers and builders are aware of the issue. Leaking exterior doors are a common problem affecting building owners and tenants, causing property damage, and requiring expensive repairs. They have been certified to meet and exceed the specifications set forth by FEMA and the National Storm Shelter Association.All images courtesy Building Diagnostics Inc.īy Adrian Gerard Saldanha and David H.
