On this page
The best rv skylight exterior cover depends on whether you need an exterior dome or an interior shade, because the listings here mix domes and shades. A tinted dome replaces the outer skylight and keeps rain out, while an interior insulator cover blocks light and heat from inside the vent. The picks here include exterior domes and interior insulator covers, and the extra picks add more of both. This roundup compares them on size, layers, light blocking, fit and warranty, so you can match the cover to the vent you have.

Where the points went
The Solar Score weighs performance, build, value, safety and warranty. For skylight covers, safety means a stated certification or a safety-relevant feature the listing names; none of the picks states one, so the safety line is empty across the group. Only the Prutomr states a warranty term, 1 year. The Prutomr leads on performance with the clearest light and heat figures, while the domes lead on weather protection as outer skylight replacements. How we pick explains the weights.
| Product | Solar Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| Prutomr Sun Blackout Vent Cover | 9.7 | 30 | 21 | 21 | n/a | 1 |
| Safoner Skylight Cover 2-Pack | 9.6 | 28 | 21 | 22 | n/a | 0 |

| Fioqe Vent Insulator 2-Pack | 9.5 | 24 | 19 | 20 | n/a | 0 |
Every total is translated into a figure between 9.2 and 9.8 with a linear formula; ranking by points and ranking by score always agree. Safety applies to powered equipment and to listings naming safety features. For the rest, 90 points form the full scale.
How to choose the best rv skylight exterior cover
Start with the vent size
Measure the vent before you order. The Safoner and Prutomr covers are 16×16 inches, the Fioqe insulator is 14 by 14 by 3 inches, the HECASA dome is 13-3/4 by 21-5/8 inches with a flange of 17-7/8 by 26 by 4-3/8 inches, and the Kojem dome is 24 by 12 by 4 inches with a flange of 28 by 15 inches. The Safoner and Fioqe fit 14×14 inch vents, and the Kojem fits 8 by 20 inch openings. Measure the opening and the flange before you buy.
Dome or insulator
An exterior dome and an interior insulator do different jobs. The HECASA and Kojem domes replace the outer skylight, block rain and leaves, and let natural light in. The Safoner, Prutomr and Fioqe covers sit inside the vent and block light and heat. If the outer dome is cracked or leaking, you need a dome replacement; if the dome is sound, an interior cover is the fix. See the best RV roof vent fan with rain sensor for the vent side of the roof.
Light blocking against natural light
A blackout cover and a tinted dome trade light for privacy. The Prutomr blocks 100% of light and 50% of heat, and the Safoner has a black inner layer for privacy. The HECASA and Kojem domes are tinted, so they block light while letting natural light through. For a dark RV, pick a blackout cover; for light with less glare, pick a tinted dome.
What comes in the box
Check what is included before you order. The HECASA dome ships with no installation accessories or instructions, and the Kojem dome ships with no mounting hardware or instructions and needs bolt-on installation with professional installation recommended. The Safoner covers come with pre-attached Velcro and extra Velcro, and the Fioqe insulator ships with a fixing accessory. A dome that needs hardware will cost more than the cover alone.
Check the warranty
Only the Prutomr states a warranty term, 1 year. The other picks state no term.
| If you need | Look at |
|---|---|
| Blackout for sleeping | Prutomr, blocks 100% of light |
| Insulation for 2 vents | Safoner 2-pack, 16×16 inch covers |
| Exterior dome replacement | HECASA tinted dome, 13-3/4 by 21-5/8 inches |
| Thick insulator that cuts noise | Fioqe, 14 by 14 by 3 inches |
Sizing Notes
- Measure the vent opening and the flange before you order: the HECASA dome is 13-3/4 by 21-5/8 inches with a flange of 17-7/8 by 26 by 4-3/8 inches, and the Kojem dome is 24 by 12 inches with a flange of 28 by 15 inches.
- Match the cover to the vent: the Safoner and Fioqe fit 14×14 inch vents, and the Kojem fits 8 by 20 inch openings.
- Check the thickness: the Fioqe insulator is 3 inches thick, while the Safoner is 0.15 inches and the Prutomr is 0.2 inches.
- Count the covers: the Safoner and Fioqe come in 2-packs, while the Prutomr, HECASA and Kojem each come as 1 cover.
