    A couple of easy questions.
    It looks like your jamp extensions are attached with some sort of gasket. Are the jamb ext ions factory installed? If not, are they precut? And what are the jamb extensions made of?
    Thank you.

      Hi Jim,
      Our jamb extensions are not connected with any gaskets. We use silicon to add the jamb extension, which is the best choice for durability and insulation. The jamb extensions are factory installed, however we do offer the option of sending them loose for the client to attach to the window. Fibertec has four different materials offered for jamb extensions: 4 finger joint pine, clear pine, oak and maple.
