RVGUARD RV Skylight Inner Dome 14"x22" Clear Window — UV-protected, Impact-resistant

RVGUARD's 14"x22" clear RV skylight inner dome is a universal replacement that brings bright, UV-protected natural light into your camper while resisting impact and weather.

If your RV skylight has yellowed, cracked, or reduced the amount of daylight coming into your vehicle, this inner dome is designed as a direct, easy-to-install replacement for standard 14" x 22" roof openings. The dome combines a white ABS interior ring with a polycarbonate clear window to maximize light transmission while protecting interiors from ultraviolet exposure. It fits common roof panel thicknesses and ships with mounting screws so you can swap domes quickly using basic tools.

Will this dome fit my RV's 14" x 22" opening?

The RVGUARD inner dome is made specifically for the widely used 14" x 22" skylight aperture and accommodates wall thicknesses of 70mm or greater. It's intended as a universal inner dome so it replaces many OEM inner domes without modification.

• Designed for standard 14" x 22" roof openings
• Compatible with wall thickness ≥ 70mm
• Works as a direct swap for most OEM inner domes

How much light and protection does the clear window provide?

The clear polycarbonate window delivers high light transmission—about 88%—so interiors get ample daylight without needing an open vent. The polycarbonate layer also blocks 100% of UV rays, helping prevent fading and lowering heat buildup compared with unprotected openings.

• Approximately 88% light transmittance for bright interiors
• 0% UV transmission protects fabrics and finishes
• Clear window lets you keep views while maintaining protection

Is the dome durable enough for road use and weather exposure?

The inner dome combines a sturdy ABS mounting ring with a polycarbonate (PC) clear panel, materials chosen for impact resistance and long-term outdoor exposure. Polycarbonate resists cracking from impacts and handles wind and weather better than standard plastics used in lower-grade domes.

• ABS ring for a solid and stable mount
• Polycarbonate window for high tensile strength and impact resistance
• Built to withstand typical road and weather conditions

How simple is installation and what tools are required?

Installation is straightforward: the dome uses a screw-on mounting system and includes the necessary screws. You’ll only need basic hand tools—screwdriver and possibly a sealant if you prefer extra weatherproofing—to complete the replacement in a short time.

• Screw-on installation with included fasteners
• Basic tools required: screwdriver; optional sealant for added protection
• Quick replacement process—no specialized hardware needed

Who is this for: RVGUARD's 14" x 22" skylight inner dome is aimed at RV owners, camper renovators, and fleet maintainers who want a reliable replacement that restores daylight, adds UV protection, and improves durability. It’s a practical choice if your current inner dome is aged, discolored, or damaged and you prefer a straightforward swap using common tools.
