Lippert RV Window Replacement — Frameless, Slider & Egress Units

Lippert (LCI) is the largest RV window supplier in North America and builds most windows on current travel trailers, fifth wheels and many motorhomes — including the frameless bonded panels used on premium models. A Lippert slider or torque-lock replacement runs $300–$750 installed; a frameless bonded unit runs $500–$1,400 because the panel is glued to the sidewall and must be cut out and re-bonded. Order by rough opening and sidewall thickness.

Lead time: 3 – 10 business days standard; 2 – 5 weeks frameless custom

Frameless bonded windows are a different job

A frameless Lippert window is a single tinted panel bonded to the sidewall with urethane and hinged at the top. There is no clamp ring to unscrew. Removal means cutting the urethane bead without damaging the wall skin, prepping and priming the substrate, and re-bonding the new panel with a controlled cure.

That is why frameless costs two to three times a framed slider. It is also why a bad install shows up as a leak six months later — the failure is almost always prep, not the glass.

Frameless panels are bonded, not clamped
Urethane needs a proper safe-drive-away and cure window
Do not wash or pressure-rinse the seam for 48 hours
Wall skin damage during cut-out adds body repair cost

Ordering: rough opening, wall thickness, tint

Lippert catalogs by rough opening and wall thickness. Get both to the sixteenth, plus corner radius and tint. On a frameless unit also record the hinge side and whether the unit is a fixed panel or an awning-style opener with gas struts.

If the coach is under warranty, check with the RV manufacturer first — window failures inside the structural warranty period are sometimes covered even when the glass is not.

Lippert RV Glass FAQs

How much does a Lippert frameless RV window cost to replace?

A frameless bonded Lippert window runs $500–$1,400 installed, because the panel is urethane-bonded to the sidewall and requires cut-out, prep and a controlled re-bond rather than a simple clamp-ring swap.

Can I replace just the glass in a Lippert window?

On framed sliders and torque-lock units, yes — glass can be cut to pattern and re-glazed. Frameless bonded panels are replaced as a complete unit.

How do I order a Lippert RV window?

By rough opening (width x height), sidewall thickness, corner radius, tint and hinge side. Standard sizes ship in days; custom sizes take two to five weeks.
