Jeld-Wen is one of those companies where you MAY get American made. It entirely depends on the product. IE: Most of their double hung windows are made here - their awning windows are made overseas. Some of their doors are made here, some overseas, depends on what you order. You really cannot be sure until the product arrives and you have the product codes.
I could not find an answer either way on their interior doors. It is entirely possible they are made here. They are what I am using because they happen to have the style I want. :)
To Jeld-Wen's credit they list where each window is manufactured and explain the prefixes etc on their product codes (way down deep in their documentation)- I could not find this info for the doors though.
