Are there any sliding windows w/ a DP rating of 60 or above?
We were trying to put sliding windows on a room in a beach house we are building that will also function as a screen porch. This would allow us to open up the room as much as possible. Are there any vinyl sliding windows that have a DP rating over 60? We have not found any and are having to go w/ casements, but it is not our first preference.
