Recreational Vehicle Windows

Recreational vehicle windows come in five types: laminated windshields, framed sliding or awning windows, frameless bonded windows, dual-pane insulated windows, and egress emergency-exit windows. Replacement costs $180–$1,600 installed per window depending on construction — framed travel trailer sliders sit at the bottom of the range and frameless bonded dual-pane coach glass at the top. Fogged dual-pane windows can often be resealed for $150–$350 instead of replaced, and most RV window work is done mobile at your site.

The five recreational vehicle window types

Almost every window on a recreational vehicle falls into one of five families, and the family decides both the repair path and the price. Getting this identification right before calling a shop saves days, because the first question any RV glass specialist asks is which type of unit you have.

Windshields are laminated safety glass and are the only glass on an RV governed by federal motor vehicle standards. Everything behind the driver is tempered, bonded or framed, and is treated as coach glass rather than automotive glass.

Windshield — laminated, one-piece on Class B and C, two-piece on most Class A coaches
Framed sliding or awning windows — aluminum frame, screwed to the sidewall, common on travel trailers and fifth wheels
Frameless bonded windows — tempered glass bonded to the sidewall with a hinge at the top, standard on modern coaches
Dual-pane insulated windows — two panes with a sealed air gap; failure shows as fogging between the panes
Egress and emergency-exit windows — oversized latch, red release, required in the sleeping area

What recreational vehicle windows cost

Window price is driven by construction and size, not by brand prestige. A framed slider on a travel trailer is one of the cheapest pieces of glass on any vehicle. A frameless bonded dual-pane on a diesel pusher is one of the most expensive.

The cost of the glass is only half the picture. Bonded windows require setup, adhesive and cure time; framed windows require pulling the interior trim ring and re-butyling the flange. Labor typically adds $150–$500 to any window job.

Framed sliding window, travel trailer: $180 – $450 installed
Framed awning or radius window: $250 – $600 installed
Frameless bonded single-pane: $400 – $900 installed
Frameless bonded dual-pane: $600 – $1,600 installed
Egress window with hardware: $350 – $900 installed
Reseal only, no glass replacement: $150 – $400 per window

Foggy dual-pane windows — repair or replace

Fog between the panes is the single most common RV window complaint. It means the perimeter seal on the insulated glass unit has failed and moisture is now inside the air gap. Cleaning does nothing because the surfaces you can reach are not the ones that are dirty.

There are two real options. A resealing service pulls the insulated unit, splits it, cleans both interior surfaces and rebuilds the seal for roughly $150–$350 per window. Or the whole insulated unit is replaced for $400–$1,200. Resealing is the value choice when the frame and gaskets are sound.

Leaks: the frame, not the glass

When an RV window leaks, the glass is almost never at fault. The failure is in the butyl tape behind the mounting flange, the sealant bead along the top edge, or a corroded frame corner that has opened a capillary path into the wall.

That distinction matters financially. A resealed window costs a few hundred dollars; delaminated sidewall from a leak that ran for two seasons costs thousands. Any owner seeing a stain below a window should treat it as urgent structural maintenance, not cosmetic.

Inspect the top sealant bead on every window each spring
Look for interior wall staining or soft spots directly below the sill
Re-butyl a framed window any time it is removed for any reason
Never seal the bottom weep holes on a framed window — they are the drain path

How to measure a recreational vehicle window

Framed RV windows are ordered by rough-opening size, not by glass size. Measure the cutout in the sidewall from inside the coach, width first then height, and note the wall thickness — a 2 inch wall and a 2.5 inch wall take different trim rings on the same window.

Frameless bonded glass is ordered by the panel itself. Measure the glass at its widest and tallest points, note the corner radius, and photograph the hinge and latch hardware. Any specialist quoting the panel will need those photographs.

Frequently Asked Questions

What are recreational vehicle windows made of?

RV windshields are laminated safety glass. Every window behind the driver is tempered glass, either set in an aluminum frame that screws to the sidewall or bonded frameless to the wall, and may be single-pane or dual-pane insulated.

How much do recreational vehicle windows cost to replace?

$180–$1,600 installed per window. Framed travel trailer sliders run $180–$450, frameless bonded single-pane windows $400–$900, and frameless dual-pane units $600–$1,600.

Can foggy RV windows be fixed without replacing them?

Yes. A dual-pane reseal service splits the insulated unit, cleans the interior surfaces and rebuilds the perimeter seal for $150–$350 per window — roughly a third the cost of a new insulated unit.

Who makes RV windows?

The dominant North American suppliers are Hehr, Kinro, Lippert (which acquired Kinro), Philips Products, Motion Windows and Peninsular Glass. The brand is stamped or labeled on the frame, usually at a lower corner.

How do I measure an RV window for replacement?

For framed windows, measure the rough opening in the sidewall — width then height — and record the wall thickness. For frameless bonded glass, measure the panel at its widest and tallest points and note the corner radius.

Are RV windows tempered or laminated?

Windshields are laminated so they hold together when struck. All other RV windows are tempered, which is why they granulate into small pieces instead of cracking when they fail.

Can RV windows be replaced by a mobile technician?

Yes. Both framed and frameless RV windows are routinely replaced on site at RV parks, storage yards and driveways, provided there is level parking and clear working room along the affected wall.
