b'Frame-In or Frame-Out.Which is best?Most callbacks for replacement applications are due to the failure or inability to integrate all 5 barriers of the wall to the new window. Replacement is different from New Construction applications because the opening has to be cleared of all unneeded parts of the old window. Theopening needs to be properly prepared to receive the newwindow. Finally, the existing trim needs to be integrated tothe new window.Two approaches There are two basic approaches to replacing existingwindows with frames of wood, vinyl or a combination ofmaterials.Frame-In. The old window frame is left in the opening with FRAME-INthe idea that the interface between the old window and thewall is sufficiently intact to provide an adequate weatherbarrier and moisture control and/or the old frame is soembedded in the wall, removal would cause unnecessaryand extensive damage. Frame-In can be accomplishedfrom inside the house (Inside-Out) or from outside of thehouse (Outside In) discussed elsewhere in this manual.While each is somewhat unique unto itself, the relativegoal is the same: place the new window in the old windowframe and sufficiently interface the weather barriers andthermal barriers of the new window to the old windowframe.Frame-Out. The old window is removed down to theerough opening, requiring a new window and its frame to be integrated with the walls weather, thermal and airFRAME-OUTbarriers.
