Camco Sunshield RV Vent Insulator: Block the Bad, Keep the Good

rv-vent-insulator-1If have shopped RV accessories online or have wandered through a RV parts store then you probably have seen the Camco Sunshield RV Vent Insulator. You either own one or you walked on by without noticing. After being guilty of ignoring this simple RV accessory for years we decided to try one after spending some time in the sweltering heat of New Orleans. We have an AC unit that at times  struggles to keep up in those kinds of conditions. After a recommendation from the RV park manager we purchased what we had always thought was a gimmick, the Camco Sunshield RV Vent Insulator.

The Sunshield Vent Insulator from Camco serves a very specific purpose. It is a 3” thick foam insulator that wedges into your interior vent- fan openings to stop heat transfer. This means it stops heat from getting in during the summer and heat from getting out in the winter.  It is a all-seasons solution. It has a reflective surface on one side to block 100% of the sun. It even features a fleece cover that is removable so you can clean it when necessary.  It will fit in any standard 14” vent opening.

To say these things work great is an understatement. After we installed the two vent insulators which took all of 30 seconds, it was a near instant improvement. The Camco Sunshield RV Vent Insulator comes with Velcro tabs for installation though we didn’t find them necessary. 30 minutes after installation, the vent insulators had dropped the interior temperature at least 10+ degrees and put a lot less stress on our AC unit. The only downside is that it blocks out the light from the vents so it can get dark inside the RV unless we open the shades on the windows.

We are interested to see the effects during the winter. With the effectiveness in handling excess heat, there is no reason to believe it cant do the opposite when it starts to cool down. We found that cracking the vent a little improves the performance by allowing all that reflected heat to escape. The opposite would need to be done during the cooler months.

For the few instances where it reached into some colder temps so far, the vent insulater did a wonderful job of keeping the heat from escaping. Particularly in the bedroom where we needed it most. Perhaps not as significant as in the summer but still a great tool for insulating during the winter.

  1. I just bought the Camco Sunshield in the hopes it will do a good job of insulating my bathroom. I have an 18 foot Sunline Saturn, love it and camped throughout this winter. Last weekend the temps went below 15 degrees, so next weekend I’ll install the Camco Sunshield and report on it.
