Overstock Window Units & Frames

Whole window units go surplus when a schedule changes late, a rough opening gets framed wrong, or a replacement job gets re-measured after ordering. Because they arrive as complete assemblies, the fit questions matter more than the glass questions.

What shows up in window units & frames

  • Aluminum, vinyl, and steel units in fixed, casement, awning, hung, and slider configurations
  • Thermally broken commercial units from curtain wall and punched-opening work
  • Complete replacement units from projects that got re-measured after ordering
  • Frames and sash without glazing, from shop overruns

Before you buy

Surplus is only a bargain if it fits and it's documented. These are the questions worth asking on this category specifically.

  • Unit size and rough opening are different numbers — confirm which one you're being quoted
  • Verify handing and swing direction on operable units; it usually can't be reversed in the field
  • Check frame depth against your wall assembly, and whether it's a nail-fin or block-frame unit
  • Look for the NFRC label — it carries U-factor, SHGC, and visible transmittance, which your energy code compliance depends on
  • Confirm screens, hardware, locks, and operators are present; sourcing them separately can cost more than the unit
  • Ask whether the glazing is annealed, tempered, or laminated, and whether the location requires safety glazing

Common questions

Can I use surplus windows and still pass an energy code inspection?

Yes, provided the unit carries a legible NFRC label with U-factor and SHGC values that meet your local code, and those numbers make it into your compliance documentation. A unit with no label is difficult to approve, because the performance can't be verified.

What's the most common reason surplus windows don't fit?

Confusing unit size with rough opening. A window ordered for a 36 x 60 rough opening is not a 36 x 60 unit, and the shim space differs by manufacturer and installation method. Always ask for the actual frame dimensions.
