Keep your RV interior more comfortable year-round by insulating your roof vent opening from the inside. The Camco Sunshield blocks radiant solar heat in summer and slows heat loss in winter, reducing the workload on your AC and furnace without blocking ventilation access when the vent is open.
Roof vents are one of the most efficient paths for solar heat to enter your RV during summer -- and one of the fastest paths for warmth to escape in cold weather. The Camco 45191 Sunshield installs on the inside of your vent frame to intercept radiant energy before it reaches your living space.
The reflective surface deflects solar radiation, while the thermal barrier layer slows conductive and convective heat transfer in both directions. The result is a measurably cooler interior in summer and a more heat-retentive cabin in shoulder seasons and winter, which means your air conditioner and furnace cycle less often and run shorter.
Reflective foil surface blocks 100% of direct UV and radiant solar energy coming through the vent opening, reducing interior heat gain significantly on sunny days.
Included hook-and-loop strips secure the cover firmly to the interior vent frame. No tools, drilling, or adhesives required. Removes quickly when you want to open the vent.
Works in both directions -- blocks heat entry in summer and slows heat loss through the vent opening in fall and winter, making it useful for full-timers and cold-weather campers.
The 16x16 inch panel is sized to cover the interior opening of a standard 14-inch square roof vent cutout, the most common vent size found across RV brands and models.
The Sunshield mounts flat against the interior side of the vent lid or frame using the hook-and-loop strips. When the vent is closed, the reflective face deflects solar radiation and the backing layer slows heat transfer. When you want to open the vent for ventilation, the cover peels away cleanly and stores flat.
This is a passive, zero-power solution -- no wiring, no batteries, no moving parts. It works in any RV with a standard 14-inch square roof vent opening, regardless of whether that vent has a fan installed.
The Sunshield is designed to install inside vents that have a vent fan (such as a Fan-Tastic or Maxxair unit) as well as standard non-powered vents. When the fan is not in use and the vent is closed, the Sunshield sits against the lid to provide insulation. Always remove or reposition the cover before operating the fan.
Boondockers and full-timers who rely on solar power have an added reason to keep the AC off longer. Using vent Sunshields on all roof vents -- especially vents that face the prevailing sun angle -- can reduce interior temperature enough to delay AC startup by one to two hours on hot days, saving battery capacity and generator run time.
The reflective surface can be wiped clean with a damp cloth. Avoid harsh solvents that may degrade the foil layer. Store flat to prevent permanent creasing of the reflective barrier. Replace hook-and-loop strips if adhesion weakens after extended use -- standard adhesive-backed hook-and-loop tape is widely available as a replacement.
The Sunshield covers the interior opening -- it does not seal the vent lid against rain or prevent exterior weathering. Inspect your vent lid seal and latch mechanism separately. Do not use this cover as a substitute for a functional vent lid.
