SIKADEER RV Vent Insulator 14″x14″x3″, 2 Piece Universal RV Skylight Cover with Reflective Surface, Skylight Shade Energy Savings Sunroof Fits for 14 Inch X 14 Inch RV/Camper Vents

I ordered these for my Rockwood MiniLite and they are great! They arrived vacuum seamed and very compressed, but went to their original shape in about 12 hours. I put these in my max air fan space in the bathroom and also in the skylight above the bed. They block out all light and made an instant difference in maintaining the inside temperature in the camper. They fit very snug and are worth every penny!

My vents are about a 1/2 inch smaller than these, length and width. Still somewhat easy to place and certainly stopes the heat and light from entering the RV.

Just what we need to block the sun and heat in the RV bathroom. It comes so vacuum packed that you wonder if it will ever be full size..but in about 5 hours it was full size. It fits very tightly into the window frame. Great value.

These work just great. They are 14". I noticed that all of the vents in my RV, with the inside trim, are about 13.5". So these really squeeze in tight. I didn't see any need to add the sticky strips that were included.I ordered 2 packs of 2. So when they showed up, there were four in the box, 2x 2-packs. Seriously overpackaged! What a pain. the two 2-packs were wrapped in plastic, then each 2-pack was shrink-wrapped super tightly. It was difficult to cut open the shrink-wrap without damaging the product, but I managed. Once I got the 2-pack open, there was another level of vacuum sealed shrink wrap, again just as difficult to avoid cutting the product.Inside these things, they're memory foam. The instructions say to let them sit out for 24 hours to expand to full size. So it stands to reason that they would squish these things down as small as possible to get them into the box and ship as inexpensively as possible. But dang, seriously a pain to unpack.I let them sit for a day and a half, and they never really did expand out to 3" thick. Maybe 2. But they stuck into the vent ports well enough, and work well.After about a day and a half, these things still weren't really 3" thick.

Bought twice. After seeing how much I liked the first one I ordered I had to order another bigger one. Works great. Don't need velcro. Takes about 3 days to fully expand...so be patient.

This vent insulator works well. Perfect fit without even having to use the velcro secures. We just pushed it up in there and it fit snug. Definately keeps that area of the Rv cooler from the hot sun while camping.

I got 2 different packages from this brand for my skylight and vent fans. They definitely keep out the light and I have noticed the camper stays much cooler. They are simple to install and in the heat of the southeast's summer are a god send. They are a little bit larger than the opening but I don't have a problem with them staying in the vents. I am using the Velcro for the skylight though as that frame is angled. I did left them "fluff" out for about 24 hours.

RVs tend to have many areas where they can loose heat in the winter and cold air in the summer. The vent fans on an rv only have a small seal area and the vent cover is a very poor insulator. Plugging the vent with these insulators eliminated the heat/cool transfer through the vents. They fit perfectly in my vent opening without any problem. The only issue with using these vent plugs is you have to remember to remove them when you need to use the vent. One comical side note is that it took about 3 days for the units to fully expand after they were removed from the packaging.
