Hi Everyone,
I’m putting in a 8′ slider door by Jeldwen (Pozzi line, clad exterior, fir interior). We’re on a hill, gable end, no overhang so I’m wanting to avoid wind driven rain issues at the sill and put in a sill pan ( Jeldwen instructions also calls for a sill pan ). However, my windows are for 2×6 walls and they don’t address the jamb extensions that are already attached. It’s end grain on fir, (not their standard “Aurora Last” wood pine) , which would wick up any water that the pan captures. They also want you to attach the sill in 4 places with screws! They say to coat the treads and holes but how effective would the calking be when it penetrates the sill pan underneath. You wouldn’t be able to put caulking in that hole. Seems like your shooting yourself in the foot doing that.
I’m thinking of trying something like in the attached picture and also not screwing down the sill. The plastic sill profile of the door might sill trap moisture that the pan collects but I’m hopping the gap between the frame and my RO would provide a limited water drain path around the sides.
I’ve got a call in to my supplier but still waiting to hear and install date is fast approaching.
If anybody has any thoughts on my idea, or has any thoughts on sill pans in general, or has experience with Jeldwen, I would love to hear. Thanks.
Tom

Here is what you need: http://www.jamsill.com/pilot.asp?pg=products1
My former boss used to use door pans (sill pans, whatever you call 'em) frequently, which we had made up by a sheetmetal friend. I believe we probably caulked underneath it to act as a adhesive, and nailed it to the framing, never to the sill (replaced a leaking water heater for my dad a year or two ago, where the previous installer nailed through the pan...I figure it's not a great plan for doors either). And, more caulking to glue the door to the pan. My boss went a bit overboard, but I'm guessing his stuff won't leak, even if the house falls in around it.
The problem I have with the pans are the lip (obviously necessary). It often makes it harder to trim out, and I imagine the flooring guy probably has some words to say about it also, but I wasn't involved there.

Thanks guys. Don't think I can use the jamsill product due to my unique measurements. The door rep is comming out tomorrow for another issue so I'll see if the install sheets are really a bunch of bull to cover thier .....'s. Seems like with this door you have to cut a notch in the jamb extensions for the back dam of the sill pan. You would still have some wood trim sitting in the pan's water if there was any. Without a slope how does any captured water escape?
