Living in a Bubble Magnetic Insulated Roof Vent Sun Cover for 16.5 in

Our review of the Living in a Bubble Magnetic Insulated Roof Vent Sun Cover finds it earns a spot on the essential gear list for RV owners who want reliable light blocking and temperature control. Built to fit most 16.5 in x 16.5 in roof fans, this cover's standout quality is its thick UV50+ insulation combined with a blackout interior that truly eliminates incoming light while helping reduce heat gain in summer and retain warmth in cooler weather. It is a practical, low-fuss solution that installs quickly and stores compactly.

Key Features

• Temperature regulation: The UV50+ thick insulation helps keep the RV noticeably cooler in hot weather and warmer during cool nights by reducing heat transfer through the fan opening.
• Complete light blocking: The blackout design forms a seal around the fan and blocks 100% of incoming light, making it suitable for sleeping areas and bathrooms where darkness matters.
• Strong magnets: Heavy duty, sewn-in magnets hold the cover securely in place against the roof fan to resist slipping during normal driving and use.
• Weather protection: The cover blocks out rain, dust and wind through a tight seal, helping protect the interior when the fan is closed.
• Compact and foldable: When not in use the cover folds down to a small size for simple storage or can be left in place without adding bulk.

Who It's For

This cover is aimed at RV owners and campers with a 16.5 in x 16.5 in roof fan (MaxxAir, Fantastic Fan and similar) who want an easy way to control interior light and temperature without modifying the fan. It fits well for people who value quick installation, low maintenance and a blackout environment for sleeping, privacy or reducing solar heat gain.

Those who should look elsewhere include owners of nonstandard or oversized roof vents and anyone who needs active ventilation while parked, since the cover creates a seal and is intended to block light and elements rather than permit airflow when installed.

Pros & Cons

Pros

• Effectively blocks light and creates full darkness for sleeping or privacy.
• Insulated construction helps moderate interior temperature during hot and cold conditions.
• Strong, sewn-in magnets provide a secure, slip-resistant fit against the fan frame.
• Folds compactly for easy storage and can remain installed without taking up space.

Cons

• Magnets are very strong, which some users noted could be improved in placement or handling but may make removal stiffer for some hands.
• Designed only for 16.5 in x 16.5 in fans, so sizing must be checked before purchase.
