Hehr RV Window Replacement — Part Numbers, Cost & Modern Equivalents

Hehr windows are found on a huge share of motorhomes and trailers built from the 1970s through the 2010s, identified by a stamped aluminum frame corner reading "Hehr" with a series number. Glass-only replacement in an existing Hehr frame runs $180–$450 per window; a complete new window assembly runs $350–$900 installed. Many original Hehr series are discontinued, so the common path is to reuse the frame with cut-to-size glass, or replace the whole unit with a current Lippert or Peninsula window sized to the same rough opening.

What they make: Aluminum-framed side windows, sliders, torque-lock and awning windows, entry-door glass
How to identify: Stamped frame corner or a sticker on the inner flange with "Hehr" plus a series number
Typical cost: $180 – $450 glass only · $350 – $900 complete window
Lead time: 3 – 10 business days for cut glass; 2 – 5 weeks for a custom assembly

How to identify your Hehr window before ordering

Every quote depends on three numbers: the rough opening, the glass size, and the series. Open the window and look at the inner aluminum flange at a corner — Hehr stamped or labeled the series there. Photograph it. If the label is gone, a shop can identify the series from the frame profile, the latch style, and the corner radius.

Then measure the daylight opening (visible glass) and the outside frame dimensions, both to the nearest sixteenth of an inch. On a torque-lock or slider, measure each pane separately — one fixed, one moving — because they are rarely the same size.

Photograph the stamped corner and any inner-flange sticker
Measure glass width x height, then frame width x height
Note the corner radius — square, 1 inch, or 2 inch
Record glass tint: clear, gray/privacy, or bronze
Note single pane vs dual pane and whether it is fogged

Glass only vs a complete new window

If the frame is straight, the latch works, and the seals are intact, glass-only is the cheaper and faster fix. A shop cuts tempered glass to your pattern, matches the tint, and re-glazes it into your existing Hehr frame — typically $180–$450 depending on size and whether the pane is curved.

Replace the whole unit when the frame is bent, corroded, or the original series is unsupported. A current-production window from Lippert or a custom builder can be manufactured to the same rough opening, which avoids cutting the sidewall — that is the expensive part of any window swap.

Discontinued Hehr series and the workaround

Owners commonly hear "they don't make that anymore" and assume the coach is stuck. It rarely is. Tempered RV glass is cut to pattern from a template, so a discontinued series is only a problem when the frame itself is destroyed.

When the frame is gone, a custom window builder fabricates a new assembly to your exact rough opening, matching flange width so it seals against your wall thickness. Give them the sidewall thickness measurement — RV walls run from about 1 to 2.5 inches and the flange must match.

Hehr RV Glass FAQs

Are Hehr RV windows still made?

Many original Hehr series are discontinued, but replacement glass is still cut to pattern for existing frames, and current-production windows can be built to the same rough opening when the frame itself is damaged.

How much does a Hehr RV window cost to replace?

Glass-only replacement in an existing Hehr frame runs $180–$450 per window. A complete new window assembly runs $350–$900 installed depending on size and whether it is a slider or torque-lock unit.

How do I identify my Hehr window model?

Look for a stamped or labeled series number on the inner aluminum flange at a frame corner. If it is missing, a shop can identify the series from the frame profile, latch style and corner radius.
