RV Glass Parts Finder

To find RV replacement glass, identify who actually made the part: Class A windshields come from the coach builder, Class B and C windshields from the chassis maker, and side windows from a supplier such as Hehr, Kinro, Lippert or Philips — the label is on the window frame. Then collect the rough opening width and height, wall thickness, glass edge thickness, and coach make, model, floor plan and year. Glass-only prices run $90–$260 for framed slider glass, $250–$700 for a frameless bonded panel, $400–$1,100 for a dual-pane unit and $600–$2,000 for a Class A windshield half.

Step 1 — identify who made the part

RV glass is sourced from three different places, and almost every failed parts search comes from asking the wrong one. Windshields on Class A coaches come from the coach builder. Windshields on Class B and C units come from the chassis manufacturer. Side and rear windows come from a window supplier such as Hehr, Kinro, Lippert or Philips — never from the RV brand on the side of the coach.

The window supplier's name is stamped or labeled on the frame, usually at a lower corner or on the inside of the sash. Find that label before calling anyone; with it, a part can often be matched in a single phone call.

Class A windshield → coach builder (Winnebago, Tiffin, Newmar, Thor)
Class B/C windshield → chassis maker (Ford, Mercedes, Chevrolet)
Framed or frameless side window → window supplier (Hehr, Kinro, Lippert, Philips)
Bus or motorcoach glass → coach shell maker (Blue Bird, MCI, Prevost)
Discontinued brands → aftermarket fabricator working from a template

Step 2 — collect the numbers a supplier will ask for

A parts desk cannot search by 'the big window over the dinette.' Every supplier searches by some combination of part number, rough opening, and vehicle identity. Assemble all of it before you call and a two-week search becomes a same-day answer.

Window supplier name and any stamped part or mold number
Rough opening width × height, measured inside at the sidewall cutout
Sidewall thickness (determines trim ring depth)
Glass thickness at the edge — 4–6 mm is single-pane, 20–28 mm is dual-pane
Coach make, model, floor plan and model year
Chassis make and year, for Class B and C windshields
Photographs of the frame corner, latch hardware and hinge

Step 3 — decide between OEM, aftermarket and fabricated

OEM glass comes from the original supplier and matches tint, curvature and hardware exactly. It is the right answer when the part is still in production and the coach is newer than about ten years.

Aftermarket glass is cross-referenced by dimension rather than part number and typically saves 20 to 40 percent. It is the standard path for discontinued coaches. Fabricated glass is the last resort — a tempered panel cut to a physical template, which works for flat side windows but not for curved laminated windshields.

OEM: exact match, highest price, best for coaches under 10 years old
Aftermarket: 20–40% cheaper, cross-referenced by dimension, standard for discontinued coaches
Fabricated to template: flat tempered panels only, roughly one week for the cut and temper cycle
Salvage: viable for rare vintage shells; inspect the edges for chips before buying

What glass and parts actually cost

These are glass-and-parts figures, before installation labor. Installation adds $150–$500 on a window and $250–$900 on a windshield depending on class and whether the panel is bonded.

Framed slider glass only: $90 – $260
Complete framed window unit: $180 – $500
Frameless bonded tempered panel: $250 – $700
Dual-pane insulated unit: $400 – $1,100
Class C chassis windshield: $220 – $500
Class A windshield half: $600 – $2,000
Window latch, hinge or crank hardware: $15 – $120
Butyl tape, trim ring and sealant kit: $30 – $90 per window

Parts that are not glass but cause the same problem

A surprising share of RV window calls end without any glass being bought. Failed latches, broken cranks, torn screens, dried gaskets and corroded trim rings all present as 'the window is broken' and all cost a fraction of a panel.

Ask a technician to price the hardware path before the glass path. If the pane is intact and the complaint is that it will not stay open, will not seal, or rattles, the fix is almost certainly hardware.

Frequently Asked Questions

How do I find the right replacement glass for my RV?

Identify the supplier from the label on the window frame, measure the rough opening and wall thickness, note the glass edge thickness to determine single or dual-pane, and record the coach make, model, floor plan and year. Those six items let a specialist match the part.

Who makes RV window glass?

The main North American suppliers are Hehr, Kinro, Lippert (which acquired Kinro), Philips Products, Motion Windows and Peninsular Glass. The RV brand does not manufacture its own windows.

Can I buy RV glass without the part number?

Yes. Aftermarket suppliers cross-reference by rough opening dimensions, wall thickness and hardware pattern, and a fabricator can cut a flat tempered panel from a physical template.

Is aftermarket RV glass as good as OEM?

For flat tempered side glass, functionally yes, and it saves 20 to 40 percent. For curved laminated windshields, OEM or a specialist RV glass fabricator is the safer choice because curvature must match the front cap mold exactly.

Where do I find the part number on an RV window?

Look for a stamped or adhesive label on the frame at a lower corner, on the inside face of the sash, or along the top rail behind the screen. On dual-pane units the label is sometimes on the spacer visible between the panes.

What if my RV brand is out of business?

Source by dimension instead of part number. Aftermarket RV glass fabricators regularly build panels for Monaco, Country Coach, National RV and Beaver coaches using shell measurements and templates.
