WanDwel RV Vent Insulator 14x22 Skylight Cover 22x14x2.8 — reflective, waterproof foam core for cooler RVs

Whether parked under hot sun or trying to sleep through early-morning glare, this skylight cover slips into standard 14 x 22 inch RV vents and provides a snug, insulated barrier. It combines a reflective silver outer face with a 2.8-inch high-density foam core and a six-sided waterproof shell to limit heat transfer, cut light, and resist moisture in bathroom or shower areas. The insert is designed slightly larger than the nominal vent size so it stays put, and silicone grip dots on every side secure it during travel—no tools or fasteners needed.

How does this skylight cover reduce heat and bright light inside my RV?

The reflective silver surface bounces sunlight and radiant heat away from the interior, while the thick foam core slows thermal transfer. Together they create a cooler cabin during summer and a darker, more comfortable sleeping space.

• Reflective outer layer deflects sun and radiant heat.
• 2.8" high-density sponge core minimizes temperature flow.
• Darkened surface reduces early-morning light intrusion.

Will the WanDwel insert fit my RV skylight vent, and how secure is it?

The insert is built for standard 14 x 22 inch vents but is intentionally made slightly oversized to produce a snug fit in vents with vertical sidewalls. Non-slip silicone dots along all four edges keep it seated during travel, making installation tool-free and fast.

• Measured for 14" x 22" vents with a 2.8" depth.
• Slightly larger dimensions ensure a tight fit in vertical-sided openings.
• Silicone grip dots prevent slipping; push-in design needs no tools.

Is this cover durable and suitable for wet areas like an RV shower?

The cover features a six-sided waterproof outer layer and a zippered removable shell that resists splashes and moisture build-up. The outer fabric wipes clean easily, and the zippered design allows for straightforward removal and maintenance.

• Waterproof casing protects the foam core from moisture.
• Zippered cover for quick cleaning or replacement.
• Easy-to-wipe material keeps mold and mildew concerns down.

How will this skylight insulator affect my RV energy use?

By reducing direct solar heat gain and slowing thermal exchange, the insert eases the load on air conditioners and heaters. Over time, less HVAC runtime translates into lower electricity or fuel consumption during trips.

• Reflective surface reduces cooling demand on hot days.
• Thick foam core improves thermal resistance for seasonal use.
• Simple removal means you can use it only when needed to maximize efficiency.

Who this fits: ideal for RV owners, motorhome and travel-trailer campers, and 5th-wheel users who have standard 14 x 22 inch skylight vents with vertical sidewalls and want an easy, tool-free way to cut heat, light, and moisture. It’s especially useful for people who sleep near skylights, use their RV in sunny climates, or need a removable, washable solution for bathroom and shower skylights. Note: curved-sided vents may not retain the snug fit; confirm vertical sidewall compatibility before purchase.
