Answer: 
Dear Scherry: Definitely not. First, cold cannot be "reflected" so reflective insulation does not work in the winter. It is only effective to block radiant infrared heat in the summer, e.g. from a hot metal roof. It also does not reflect warmth back into a room, because warm air is not radiant.
All "reflective" insulation also requires you to build / create a sealed air pocket on one side, which Read More
Dear Scherry: Definitely not. First, cold cannot be "reflected" so reflective insulation does not work in the winter. It is only effective to block radiant infrared heat in the summer, e.g. from a hot metal roof. It also does not reflect warmth back into a room, because warm air is not radiant.
All "reflective" insulation also requires you to build / create a sealed air pocket on one side, which provides 99% of the insulation value. If you install it under a metal roof that gets hot in the summer, for example, you must create an air pocket on the roof side. This air pocket must be carefully sealed to prevent air leaks.
Depending on how your camper is constructed, you may be able to fill the area under the bed or insert an insulation panel under the mattress. Roxul ComfortBatt is the best option to fill spaces, and ComfortBoard would work for a panel (or two) under the bed. See: Roxul ComfortBoard Model # RXCB11224, Home Depot Internet # 206789748 Store SKU # 1001748089 and Roxul ComfortBatt Model # RXCB351525, Home Depot Internet # 202090820 Store SKU # 974419
DO NOT install foam board under your bed -- a common mistake. Foam board is very flammable and must be covered by a thermal barrier in any occupied space, e.g. 1/2" drywall. This obviously won't work in a camper.
I hope this is helpful.

Dear iPlus10: No reflective insulation product is effective in winter because cold cannot be 'reflected' and warm air, e.g. inside a house, is not radiant -- so they cannot block the cold, or keep warmth inside your home.
Reflective products also require you to build a sealed air pocket on one side, which provides most of the insulation value -- e.g. a gap under a hot metal roof. This is not possible Read More

Home Depot offers another product, however, that is effective winter and summer -- and easy to install: Owens Corning Model # GD01, Home Depot Internet # 202257272 Store SKU # 744925. This will give you R8 performance, winter and summer.
I hope this is helpful.

Dear Lover of Texas: First, reflective insulation can cause major problems on windows and their frames in the summer due to heat gain, including cracked glass and melted vinyl. Based on the time of year, however, I assume you want to improve insulation for winter. In that case, reflective products will be nearly useless.

Dear Lover of Texas: First, reflective insulation can cause major problems on windows and their frames in the summer due to heat gain, including cracked glass and melted vinyl. Based on the time of year, however, I assume you want to improve insulation for winter. In that case, reflective products will be nearly useless. The shiny surface is only effective in summer when there is radiant heat to reflect; nothing can "reflect" cold.
Unfortunately, the only real solution is replacement windows. Home Depot offers a number of options plus installation services. Special glass coatings are typically included to match summer / winter heat gain and exposure.
I hope this is helpful.

Answer: 
Dear Jess: No. First, reflective products are only effective if you build / create a sealed air pocket on one side. This would not work with your rigid insulation box. I assume you are using foam board for the box, so just increase the thickness or add another layer to boost the insulation value -- and be sure to create a tight air seal around the edge, e.g. with weatherstripping foam.

CUSTOMER REVIEWS

Rated 4.2 out of 5 by 27 reviewers.
Rated 5.0 out of 5.0 by Worked great! I used this insulation on the floorboards of my 1970 Corvette to keep the engine and exhaust heat out and so far it is working great. Before, after driving for about 40 minutes I could feel the extreme coming from under the car. Now it just stays comfortably warm. May 3, 2016
Rated 1.0 out of 5.0 by wrong measurement It was at least 1 1/2 feet short. Distributor promised replacemnt, over a month ago but have not received it. April 12, 2016
Rated 2.0 out of 5.0 by NOT FOR COOLER CLIMATE ZONES Before installing this barrier, I went to read up on it. Several energy webpages were saying its not practical in cooler zones, mainly because you want to capture the solar heat on your roof to warm your attic, this barrier will prevent that in the winter/colder months. If you run your air conditioner 7 or 8 months out of the year ,this barrier should help. March 25, 2016
Rated 5.0 out of 5.0 by used this product for underside of wall cabinets We bought this product for an unusual use. Daughter and son-in-law have hot water baseboard heating in home. I wanted to install 15" deep wall cabinets over the heating. We stapled the foil product to the bottom of the cabinets so the heat would not absorb into the cabinets and instead reflect back into the room. It seems to work well for our needs. On sale at Home Depot so bought some more for a future project. February 23, 2016
Rated 5.0 out of 5.0 by Easy installation Haven't gotten to test out how well it reflects heat, but at least it is easy to put up. November 30, 2015
Rated 4.0 out of 5.0 by Colorado Springs Packaging was poor but the product was what I expected. Vey good value as a super buy. November 3, 2015
Rated 5.0 out of 5.0 by Radiant barrier I sed this material to cover house fan opening during the winter. It worked great! June 9, 2015
Rated 1.0 out of 5.0 by Size of the product is not the size on the package The size of the roll varied from one to the other. It was any where from a 1/4 " to 1/2 " short on the width. So you could not run the barrier over two joist at one time. And trying to return it and get the same price was impossible. April 27, 2015
