Transom Windows FAQs

  • Also known as “transom lights”
  • Height ranges from a few inches to a couple feet
  • Usually rectangular for interior doorways
  • Typically arched, aka fanlights, for exterior entries
  • Start at $100 for non-operable vinyl, wood or aluminum frames
  • Cost increases for ventilated options or more detailed designs


When considering adding a transom window to an interior space, reminds us that the structural requirements will play a critical role in your decision. For standard eight-foot ceilings, your choices will be limited to narrow models; whereas, high ceilings can accommodate taller designs. Also, installation will be simpler in non-load bearing walls than load-bearing walls which might lead to opening up bigger sections for additional support. And if installing a transom window in an exterior wall, the additional step of weatherproofing will also be necessary.


After deciding that adding a transom window is feasible for your space, then comes the fun part of choosing your design! There are countless options available and sure to be one that compliments your building’s architecture as well as your personal decorating style.
