Review on ArtisLu Insulator Protection Reflective Surface 22X14X3In by Chuck Hernandez

Fits perfectly in my RV's skylight! I can definitely tell the difference in the temperature in the bathroom. This will keep you warm in the winter and cool in the summer. It will also help protect my plastic van shower from yellowing that can result from constant exposure to the sun. I was looking for this vent cover last year, when i first bought my RV but all i could find was the standard 14" x 14" size. I'm glad it comes in a larger size now! I would recommend this vent cover to anyone highly recommend to a motorhome!
