Upgrading your windows is a common home improvement that creates a higher level of efficiency in your house. Moving from single paned windows to double or even triple glazing is a smart move, but is it always necessary to install replacement window frames when changing out the windows?
Detailing the Construction of Your Windows
In order to decide whether frames are needed, you need to first understand the construction and design of your windows.
There are three basic components of an operable window - the glazing, sash and frame. Glazing is the industry term for the glass pane(s) that make up the clear viewing area. A new window may be double glazed (two panes) or triple glazed (three panes) and the space between the glazing might be filled with an inert gas for added insulation value.
A window sash is found in operable windows or those that can be opened. Fixed windows are generally just glazing in a frame. Sashes are the wood or vinyl trims around the glazing that seals in any air or gas and provides the ability to move the panes beyond the stationary position of the window frame.
Window frames are the outside border of a window system which is tied into the framing of your house. They can be made from timber or uPVC, as well as composite products. The sash is attached to the frame with brackets or mechanisms that allow for opening and closing.
Does the Frame Always Need to Be Replaced?
In the case of fixed window replacement, removing the unit will require the removal of the frame and so a replacement will be needed. But it may be another story with operable windows, depending on the overall condition of the product.
Even if the sash and mechanisms are in good shape, when you upgrade to double glazing for better efficiency these elements will need to be changed out as well. The window frame is another story. Good quality window frames can last 25 years when well taken care of. It will make your home improvement project much more affordable if this component does not need to be purchased and installed.
Have a qualified window contractor inspect the condition of your frames. They may find structural damage or deterioration that you cannot see and recommend getting replacements. However, they may also find that the window frames are in fine shape and work with you to find sashes and glazing that will fit in the existing frame. Trust an experienced contractor to help make this decision. And know that good quality window frames are an investment in your home.
