XMK RV Skylight Replacement Bundle 14" x 22" Inner & Outer Dome Kit — 26" x 18" Flange, UV-Resistant White with Polyurethane Seala

Replace a faded, cracked, or leaking RV shower skylight with a matched inner and outer dome set engineered to trap air between layers for improved insulation and to let natural light into your camper or motorhome. This kit includes a thicker polycarbonate inner dome, an anti-UV coated outer dome, self-leveling white polyurethane sealant, and hardware so you have everything needed for a single repair job.

How does this skylight bundle reduce heat transfer and protect interior finishes?

The kit uses two domes spaced to create an insulating air gap that slows heat flow into the cabin, and the outer dome carries an anti-UV surface to limit sun-driven fading. Together they moderate interior temperatures while preserving nearby surfaces and fabrics from UV damage.

• Two-piece design creates an insulating dead-air space.
• Outer dome features UV-resistant coating to block damaging rays.
• Thicker polycarbonate resists impacts and weathering better than thin plastic.

Will these domes fit my RV opening and ceiling thickness?

This bundle is built to fit standard 14" x 22" roof openings; outer flange measures 26" x 18" to overlap typical cutouts. It accommodates ceiling thicknesses greater than 4" and includes predrilled mounting patterns you can adapt to your vehicle.

• Inner/outer dome nominal opening size: 14" x 22".
• Outer flange: 26" x 18" for full coverage of standard cutouts.
• Inner flange: 16" x 23 7/8" to match interior trim and mounting points.

How durable and weather-resistant are the domes and sealant?

Both domes are molded from thicker polycarbonate for higher impact resistance and longevity in outdoor conditions. The included white polyurethane self-leveling lap sealant forms a flexible waterproof bond to help prevent leaks while accommodating roof movement.

• Thicker polycarbonate resists cracking and hail impact better than thin acrylics.
• Anti-UV coating on outer dome reduces yellowing and surface degradation.
• Self-leveling polyurethane sealant provides a durable, weatherproof seal.

What colors and light transmission options are available?

XMK offers this skylight bundle in three finishes so you can choose balance of privacy, glare reduction and brightness. Smoke gray lowers glare and solar gain, white diffuses light for softer interiors, and clear transmits the most daylight.

• Smoke gray: reduces heat and harsh sunlight while allowing daylight in.
• White: softens and diffuses light for comfortable interior illumination.
• Clear: maximizes natural light for brighter spaces.

Who is this for: This XMK RV Skylight Replacement Bundle is designed for RV owners, camper renovators, travel trailer and motorhome technicians who need a full replacement solution for a 14" x 22" roof opening. It suits anyone replacing a cracked or yellowed dome, improving cabin comfort with better insulation and UV protection, or upgrading to a coordinated inner-and-outer assembly for a long-lasting repair. The kit is also useful for food trucks or tiny homes using the same standard skylight size and seeking an all-in-one package that includes sealant and mounting hardware.
