Selecting the suitable frame style when installing new windows
Last week, I told you how to measure for your vinyl replacement windows when replacing aluminum windows. Now that you are prepared to order your new vinyl replacement windows, we need to have to speak about the different frame style possibilities offered. In most of the country your options are restricted to either new construction or replacement frames. New construction frames come with a nailing fin to attach the frame to the studs during the construction of the new house. The replacement frame is essentially the new construction frame minus the nailing fin.
But in the west, exactly where stucco properties are widespread, producers came up with a third variety of frame named a retrofit frame. The retrofit frame has a fin about 2 inches wide, located flush with the outside face of the window. This is the greatest choice when replacing old windows, but not all jobs will accomodate a retrofit frame application. So let's discuss how to establish which frame is going to perform for you.
If you have a stucco exterior, retrofit is the way to go. You install the new window from the outside, and the flush fin covers the old aluminum frame that you are going to leave in place. Then you screw the new window in using deck screws via the side channels as effectively as the finger rosary top header. We will get into more detail on the actual installation in a future post. If you have a stucco exterior, but there is a wood trim around the opening of the window exactly where the flush fin would commonly go, you can nevertheless use the retrofit style frame. You would require to get rid of the wood surrounding the opening, install the retrofit window, then buy and install new wood trim. The old trim will no longer fit since the retrofit window frame dimensions will be larger in width and height than the old window frame. Another option is to install the retrofit fin on top of the wood trim. You can do this as long as the depth from the face of the wood trim to the point in the residence of the innermost portion of the old aluminum frame is less than three inches deep. The reason is since a great good quality retrofit window will have a three inch frame depth from the back of the flush fin to the innermost portion of the frame. That innermost part requirements to be further into the house than the innermost element of the aluminum frame so that the aluminum frame will be hidden right after we apply the inside trim. What if you have brick about the window openings? Or siding? Then what? Effectively, if you can install the window against the face of the brick or siding and nonetheless have the innermost element of the vinyl frame be additional into the home than the old frame, then you can use the retrofit style frame. If not, then you have to use the replacement style frame,then use trim to finish the outside. If you are in a position to get a retrofit frame with a fairly thin fin, you can also trim down the fins so the window fits amongst the brick or wood. That would remove the require to trim out the outside. Some manufacturers of retrofit frames will have grooves in the back of the retrofit fins. You merely run a utility knife in the groove till you are in a position to break off that piece of the fin.
The major point to don't forget when determining no matter whether censer site or not to use a retrofit frame or a regular replacement frame is that in order to flagon use the retrofit frame there needs to be much less than 3 inches from the outside point where the flush fin will rest to the inside point in the room exactly where the old frame ends. If it is much less than 3 inches, go with the retro, more than three inches, use the replacement frame and add trim to the outside in lieu of the flush fin.
Next week I am going to clarify the method of removing the old aluminum window.
