Living in a Bubble Magnetic Insulated Roof Vent Sun Cover 16.5" x 16.5" White, Blackout UV50+ with Sewn-in Magnets

Magnetic insulated roof vent cover for 16.5" x 16.5" MaxxAir and Fantastic RV fans that blocks light, reduces temperature transfer, and snaps on with sewn-in magnets for a secure fit.

Designed for road warriors and weekend campers, this Living in a Bubble vent sun cover fits most 16.5" x 16.5" roof fan openings to keep interiors darker and more temperature-stable. The heavy-duty magnets are stitched into the hem so the cover stays put in travel and windy conditions, while the UV50+ insulated material reduces heat gain in summer and heat loss in cooler weather. It’s lightweight, foldable for easy storage, and compatible with common MaxxAir and Fantastic fan models.

How does this cover help control temperature inside my RV?

The cover uses a thick, UV50+ insulating layer to slow heat transfer through the fan opening. That reduces solar heat gain on hot days and helps retain warmth when it’s cold outside.

• UV50+ rated fabric blocks damaging sun rays and reduces radiant heat.
• Multiple insulation layers create a thermal barrier at the fan opening.
• Sealed fit around the vent minimizes drafts and heat exchange.

Will it really block all light coming through the fan?

Yes — the blackout construction and snug magnetic seal are built to eliminate gaps so no light filters through the fan opening. It’s useful for daytime naps, early-morning starts, or any time you want complete darkness.

• Opaque, dark-proof fabric prevents light penetration.
• Sewn-in magnets ensure the cover presses flush against the fan frame.
• Designed specifically for 16.5" x 16.5" roof vents to avoid gaps common with generic covers.

How easy is installation and storage when I don’t need it?

Installation is tool-free and quick — simply align the cover over the fan frame and let the sewn magnets attach. When not in use it folds compactly for stowing in a cabinet or under a seat.

• Tool-less snap-on fit using strategically placed magnets.
• Slip-resistant magnet placement prevents shifting while driving.
• Folds small for easy storage or can remain in place between trips.

Is this cover durable enough for travel and outdoor use?

The cover is built with robust materials and reinforced seams around each magnet to withstand road vibration, wind, and repeated use. It’s intended for regular RV life, from full-time travel to seasonal camping.

• Sewn-in, heavy-duty magnets resist slipping and detachment.
• Sturdy outer fabric resists UV damage thanks to a UV50+ rating.
• Reinforced stitching around stress points increases longevity.

Who is this for? This Living in a Bubble magnetic insulated vent cover is made for RV owners, vanlifers, and campers with 16.5" x 16.5" MaxxAir or Fantastic-style roof fans who want a simple, reliable way to darken the interior and improve temperature control. It’s especially useful for parents with sleeping children, shift workers needing daytime rest, or anyone who wants to reduce heat gain or heat loss through the roof vent without modifying the fan.
