Camco 45149 RV & Marine 14x14 Vent Sun Shield

Roof vents are great for airflow, but on a sunny day that same 14 by 14 opening turns into a skylight that dumps heat and glare straight into your cabin. The Camco 45149 Sun Shield fixes that. It's a light-blocking panel that snugs up against a standard 14 inch by 14 inch roof vent and stops the sun before it ever gets inside.

The face is black nylon ripstop, so it soaks up light instead of letting it filter through. Behind that is a silver reflective backing that bounces radiant heat back out rather than letting it soak into your headliner. The panel measures 16-1/4 inches square, a little larger than the 14 by 14 opening, so it covers the frame and seals off the light around the edges. It's a simple idea, and it works.

Installation takes a couple of minutes and no tools. Five hook-and-loop fasteners come in the box, each one an inch by an inch and a half. You stick the loop side around the vent frame, press the shade into place, and you're done. When you want the light and the air back, peel it off and roll it up. It goes right back the next time you need it, and because there's no adhesive on the shade itself, nothing gums up your vent frame and there's no sticky residue to scrub off later.

If you've ever tried to nap in an RV in the afternoon with a skylight vent overhead, you know the problem. The light comes straight down onto the bed. This shade blacks it out. It's also a real help in summer, since roof vents are one of the biggest heat leaks in a rig, and a reflective panel over the opening takes a noticeable bite out of how hard your air conditioner has to work. A cooler ceiling means the whole rig feels less like an oven when you climb back in after a day out. It earns its keep in the shoulder seasons too, when you want the vent covered overnight but open during the day.

The same thing applies on the water. Plenty of boats run 14 by 14 deck and cabin vents over the v-berth or the galley, and a cuddy cabin under a midday sun heats up fast. Drop this shade over the vent and the berth stays cooler and darker, which matters if anyone's trying to sleep aboard while the sun's still up. Because it's nylon ripstop, it shrugs off the occasional splash and packs down flat when you don't need it.

There's a privacy angle too. With the shade in place, nobody's looking down through your vent from a neighboring rig or a dock. You can also leave the vent cracked open behind the shade for a little airflow while still knocking down the direct sun, or close it up completely for full blackout. The panel doesn't care whether the vent is cranked open or shut, so how you use it is up to you.

Ripstop nylon is woven with a reinforcing grid, which means a small nick won't run into a tear, and that matters for something that lives on a roof and gets handled a lot. When the season's over, the whole thing folds down to nothing and stores in a drawer. Give it a shake or a wipe if it picks up dust, and it's ready for the next trip.

It's sold as a single shade, so if you've got more than one 14 by 14 vent you'll want one per opening. Simple, cheap insurance against heat and glare, and the kind of thing you'll wish you'd bought sooner. Keep one on the shelf and you'll reach for it every summer. First-time owner or full-timer, this is an easy upgrade that pays off the first hot afternoon.
