There is a pressure at which a sliding door was sprayed with water in a laboratory and did not leak; on this coast, it is the most useful number on the label. Under the A440 standard, every sliding door installed in an Oregon wall carries a performance grade, and the grade sets two tests. The structural test is the wind pressure the door held, one and a half times its design pressure. The water test is 15 percent of the design pressure: a PG15 door was sprayed at about 2.9 pounds per square foot of wind pressure, the lowest the standard allows; a PG20 at 3.0; a PG30 at 4.5.
A PG30 door has been tested to keep rain out under more than 1.5 times the wind pressure a PG15 door was tested to, and the difference lies in the sill dam, the interlock, and the weep design. On a coast where the storm that leaks is the ordinary winter storm, that number is bought at the time of order, or not at all.
Why the label, and not the warranty
The reason to buy the door on its water test is that the warranty does not cover the storm. Milgard's replacement-product warranty, one of the documents that comes with a door VResh Construction installs, excludes "water intrusion caused by wind-driven rain due to high-wind events" in so many words. It also excludes installation and any "failure to properly incorporate the Product into the building envelope," assigns caulking between the door and the siding to the owner as maintenance, and states that "Milgard does not warrant its test results or certifications." Other makers' documents carry their own exclusions, and the one that comes with the brand on the order is the one that counts. The paper covers the door as a manufactured object. What keeps a Lincoln City living room dry in a southwest gale is the grade the door was built to, the sill pan and flashing under it, and the sealant around it, and only the first of those is printed on anything.
One lot, one number
The pressure a storm exerts on a particular door comes from the code's tables for the coast's special wind region, the lot's exposure, and the door's location on the house. A lot on the beach is Exposure D, the code's open-water category, and the same category extends to the shore of Devils Lake, 3 miles long, where the building department finds the open-water fetch the code requires. An 8-foot slider near a corner of a two-story house on such a lot works out to roughly 28 pounds per square foot, lower than a small corner window's figure because the tables assign less pressure as the glazed area grows, which is a PG30 door, and a grade above the number rather than at it is the better order, because the water test rises with the grade. On a street the department treats as open terrain, the figure is roughly 24, and a PG25 covers it; on a sheltered lot it is roughly 16, and a PG20 does. The department determines the exposure where it is not plain from the lot, and the estimate states which category the door was ordered to. The grade is not visible from inside the room. It is in the frame section, the height of the sill dam, the interlock where the panels meet, and the rollers under a heavier panel.
The installation is where the other two things the warranty leaves out are settled, and a Lincoln City slider estimate from VResh specifies them: the sill pan under the door and the flashing into the wall, which the main sliding door page describes, and the sealant, with a note that the warranty makes it the owner's to keep up. One more line from the document matters on a coast with many houses that stand empty for weeks: a fault the maker traces to disuse is excluded, and its own measure of use is panels "opened and closed monthly."
