Reflectix/Insulating Closet

Our Trilogy resides in full sun…Florida. The cap takes the brunt of it all day. Gave Reflectix a try and so far really like the results. Infrared temp., gun on completed closet wall, it measured 12 degrees cooler than the other side without Reflectix. Also covered the shower skylight, which had an immediate impact (picture upside down). We used to keep the bathroom doors closed to keep it cooler upstairs. No longer necessary. Added to the fantastic fan caps and the vents below steps, no use in cooling the belly and storage.

Igray, I plan on doing mods similar to these as soon as we get our 36RL. In fact, I would have eliminated the shower skylight if we had ordered. Do you know if the vents at the steps serve a purpose for some type of air flow? I can't imagine why they would be there.

I never thought about Reflectix in the front cap closet, but that is a good idea! We make a point to make sure the closet door is closed because of how warm it is in there. I think I'll install some before we load clothes and stuff in.

Last August, we stayed a week in LA(lower Alabama). The first couple of days the AC had to work real hard to keep things tolerable. The next day we went to CW and bought 2 rolls of the Reflectix. Cut them to the proper lengths, slid them between the windows and the day/nite shades. Used clothes pins in a couple places to hold them. Made a world of difference. There was nothing outside to see anyways. Just roll the pieces up and store in an overhead compartment.

Not sure what if any purpose the vents serve, my guess is something to do with the furnace, which we never have used. The vents are easily removed 4 screws.

Last night with the closet only partially completed the bedroom AC ran much less frequently. The completed closet walls are within a couple degrees of the walls throughout the fifth wheel. No real reason to keep the closet doors closed, which was never really solution as the hot air was slowly seeping into the bedroom anyway. Correcting the insulation problem is not that hard.
Reflectix has a good website with videos. One to the most important steps if you are trying to keep the hot air out, use 2 or 3 strips (spacers) of the Reflectix to create a space between the wall board and Reflectix, at least a ½ to ¾ of an inch gap. This greatly increases the R factor. 3M, 10 pound indoor/outdoor two sided tape was very effective.

Lowes carries Reflectix in stock; we ordered it through Home Depot, 2 ft. by 100 ft. roll, $75.00, better deal. Sounds like a lot, but once you get started, you will be surprised how many other place there are to insulate. No need for the type that has perforations for stapes unless you plan use staples, again a little less expensive.

Cap closet complete, did not cover the cedar or the two sections of padded material above shelves. Closed the closet doors to test temperature, inside the closet was only slightly warmer than the bedroom. Temperature outside over 90, cap and closet full sun. Front AC no longer running constantly. I will call that a success.

Now, go to the roof units and pull the cover and do the same to the compressor & condenser units and the inside of the covers. You will find they will work much better also.

lgray, how did you attach the reflectix to the vent lid?
Can you open the vent without the stuff blowing away?

My thought is that using it on the vent covers, you are creating a lot more heat on the plastic covers; same thing with front cap, you are reflecting the heat back into it rather than letting it absorb the heat. Long term use will tell.
