Keep the warm air inside with a vent insulator

By Bob Difley

RVs are meant to be used not just in summer and not just when it is warm and sunny. Achieving comfortable living in your RV when the outside is either too cold or too hot is a challenge.

One way to prevent heat from escaping during colder periods or to prevent hot air from entering under a full desert sun is to stop the unwanted flow of heat or cold through your overhead vents.

Camco Sunshield RV Vent Insulator with Reflective Surface fits snugly in an RV vent opening with a full 2.75″ of foam to help stop heat transfer, keeping your RV cooler in summer and warmer in winter. The reflective surface blocks 100% of the sun’s damaging rays. Fits standard 14″ RV vents.

My sole roof vent is a fantastic fan. I will have to crawl across the roof to install the reflectix foil between the cover and the fan.

Does anyone else have trouble using this with the reflective surface pointing skyward as intended? With the crank handle to the roof vent it will poke a hole in the reflective surface, correct? I always invert them even though that isn’t how they’re designed to be used.

If you use one of these vent insulators, be sure to leave the vent cracked open, because condensation will build up between the insulator and the vent. I now have a water-stained ceiling around my vent to prove it.
