VanEssential Magnetic Insulated Roof Vent Sun Cover for MaxxAir & Fantastic Fan 16.5" x 16.5" — Cool Gray, 5mm Reflective Insulati

VanEssential's Magnetic Insulated Roof Vent Sun Cover is a snap-on, reflective sunshade made to fit 16.5" x 16.5" MaxxAir and Fantastic Fan flanges to reduce heat gain and glare through your roof vent.

This vent cover pairs a reflective, double-foiled insulation core with a magnetic perimeter to create a secure, easy-to-use barrier for rooftop vents. Designed for camper vans, RVs, and conversion vans, the Cool Gray fabric and ripstop polyester exterior resist UV damage while the 5.0mm aluminum XPE layer reflects radiant heat. It installs and removes in seconds, stores in the included sack, and is built to hold up under regular outdoor use.

Will this cover fit my MaxxAir or Fantastic Fan roof vent?

If your fan has a 16.5" x 16.5" flange, this cover is designed to align and attach along the full roof surface. The magnetic edge grips metal roof surfaces to create a fast, tool-free seal. Note the product cannot seal properly for fans with a shallow mount where knobs or controls hang below the roofline.

• Compatible flange dimensions: 16.5" x 16.5"
• Works with MaxxAir and Fantastic Fan models using full-surface flange contact
• Not suitable for shallow-mounted vents with protruding knobs
• Quick attach/remove via integrated magnetic perimeter

How does the insulation reduce heat and light inside my van?

The core is a 5.0mm double-foiled aluminum XPE layer that reflects up to 95% of radiant heat away from the vent opening. Coupled with the UV-resistant polyester exterior, it lowers solar gain and reduces indoor brightness without relying on adhesives or permanent fixtures. This helps keep temperatures lower and interiors more comfortable during sunny conditions.

• 5.0mm XPE with double foil reflects radiant heat
• Reflectivity reduces light and direct solar gain
• Durable outer fabric resists UV fading and tearing
• No permanent hardware or roof alterations required

How easy is it to install, remove, and store the cover?

Installation is a simple magnetic snap-on: place the cover over the vent opening and the magnets cling to the roof surface. Removal is just as quick — pull the cover free and fold it into the included storage sack. The compact storage option keeps the cover protected when not in use and makes it convenient for road trips.

• Tool-free magnetic attachment in seconds
• Lightweight construction for one-person handling
• Includes storage sack for compact transport
• Quick to remove when vent operation is needed

What durability and care can I expect from this vent cover?

The outer layer uses ripstop, UV-resistant polyester to resist tears and sun degradation across seasons. The insulation core maintains its reflective properties while the magnetic edge keeps a reliable hold on metallic roof surfaces. Routine cleaning with mild soap and air drying will keep it functional and looking fresh.

• Ripstop polyester resists rips and UV fading
• Magnetic perimeter built for repeated use
• Clean with mild soap; air dry fully before storing
• Store in the supplied sack to prevent dirt and damage

Who this is for: VanEssential's Magnetic Insulated Roof Vent Sun Cover is ideal for vanlifers, RV owners, and camper converters who use 16.5" x 16.5" MaxxAir or Fantastic Fan flanges and want a removable, protective barrier against heat and glare. It's particularly useful for travelers seeking a non-permanent, low-effort solution to lower interior temperatures, protect interior finishes from sun exposure, and improve daytime comfort while parked under direct sun. If your fan is shallow-mounted with controls hanging below the roofline, this cover will not fit; otherwise it offers a durable, quick-install option that tucks away neatly when not needed.
