Beautiful window on color wall

If you have experienced drafty, foggy or otherwise damaged windows, you were likely advised one of two things: a) you should replace your windows, or b) you should replace your ‘sealed units.’ The latter is often proposed as a cost effective alternative to a full-on replacement– but what is best for you? Consult Marcotte Glass’ guideline below to inform your decision.

Sealed Unit

A sealed unit refers to the glass (or glazing) portion of the window. It sits inside the frame of your window, usually consisting of two panes of glass built around a pocket of air. A plastic, metal or rubber spacer is run around the frame to seal and separate the glass.

Full Window

A full window includes a frame, a sealed unit and hardware. Vinyl, wood and aluminum are all common types of frames. Sealed units include glass and a sealed pocket of air (see above). Hardware comes in all shapes, sizes and functionalities.

When To Replace A Sealed Unit…

If your windows are less than 15 years old and in good condition, but you are experiencing fogging between the panes of glass, sealed unit replacements are a cost effective solution.  Sealed unit replacements are also done in cases where the glass is broken but the window frame is not damaged.

When A New Sealed Unit Is Not Enough…

Sometimes a sealed unit replacement may not be the answer to your problem. The following are some signs that a full window replacement might be what you need:

  • If your existing window frames are rotten, damaged or warped
  • If your existing windows are currently using single pane glazing
  • If your home is drafty and cold through the winter months (typically caused by a combination of warped/damaged frames, deteriorating caulking/sealants, and/or single pane glazing).
