Rated 5.0 out of 5.0 by We installed this in the attic. It really works. I saw this in an attic before and wanted to install it in ours. We installed the Reflectix insulation and the attic became cooler as we progressed. It cost us an eighth ofwwhat Costco wants. All the tools we needed are a T-50 staple gun, a utility knife and a pair of large scissors. I strongly suggest buying several boxes of staples. It took us four hours with doing planning the day before. Leave a gap on either side of the roof peak vent. We used a 2 foot by 6 foot piece of 3/4 inch OSB to stand on ( one for each of us) to save us from having to stand on the ceiling joists. Our AC Guy saw it when we finished and said it will take a load off of the attic-mounted air handler. We also put in a deck in the attic to store our Christmas decorations (we have a lot) and a few other items. I went up there today when it was over 80 outside. It was the same in the attic as outside: just over 80. Saving on AC this summer and getting rid of storage will make this break even before Christmas. Oh yes....this is not a beginners project as no instructions are given. Look at the Reflectix online brochure. Study it. This is a special order item. Get it delivered to your home. April 22, 2014
Rated 4.0 out of 5.0 by Pole barn insulation Product arrived in a very timely manner. Very easy to work with. Only needed a few basic tools to install. We used a utility knife, straight edge, and a stapler with 1/2 inch staples. July 30, 2014
Rated 4.0 out of 5.0 by Have to wait and see.... I see a great many applications for this product in many areas of the home and will be using it in the future. Overall this product is wonderful, excellent consistency and quality in its fabrication. Currently being used primarily in the crawlspace of the home. Wrapping over the old insulation of the ducts to tighten, seal and clean everything up. (see attached) I will also be using this product as part of an insulation and vapor barrier system I'm building for the walls. The reflective qualities of the product should also prove to be very beneficial in helping to light up the space when you do inspections or need to do any repair work under the house. My only concerns will be the long-term stability/performance of the product. Only time will tell if drying, cracking or flexibility becomes an issue but I don’t anticipate any problems.

Rated 5.0 out of 5.0 by good energy saver I installed 2 rolls of the reflectix 4' x100' radiant barrier in my attic as well as a 10W solar gable fan. The measured temperature of the attic has dropped 10-15 degrees even though I have only done about 40% of the attic space with the barrier. I recommend using a lightweight staple gun like a JT21 to attach the product to the trusses since it may involve a lot of stretching and working in tight spaces. August 9, 2010
Rated 5.0 out of 5.0 by Very easy to install, no mess, looks great too Compared to all other types of insulation this is easy and clean to install. I used on HVAC supply ducts. No fibers or dusting from the product at all. Cuts easily with a scissor or utility kife and straight edge. Very strong and lightweight at the same time. I simply made spacers out of leftover strips of the material to get the best R factor as the air space doubles the R. Metallic tape sticks very well. While there are other products with higher R factors, none are as easy and clean to install. Highly reocmmended. March 27, 2012
Rated 5.0 out of 5.0 by Reflectix Rocks An absolutely outstanding product. We used Reflectix to insulate the duct work in our basement. Due to the very small tolerances we required a thin, flexible insulator and this was the only fit. Using the easy to follow instructions we have already seen a noticeable drop in our utility bill whilst seeing an increase in whole house comfort. The larger 4ft roll cuts easily, if required, and makes installation a breeze. We did a cost comparison against fiberglass and Reflectix worked out to be considerably more affordable whilst offering comparable or better insulating properties. November 13, 2010
Rated 5.0 out of 5.0 by Insulated the heat pump with it My sister's house in Phoenix AZ did not have insulation on the return air ducts running through the attic. I bought a 4'X 125' roll of Reflectix insulation, insulated all the return air ducts, coated the exterior of her heat pump air handler (factory insulated with 1" fiberglass to about R3?), had enough left over to coat the walls and ceiling of the mechanical space in the attic that the heat pump is located in. Had 16' left over, and insulated her garage roll up door as well. I also use this in my motorhome to cover the windshield, roof vents, and some windows. It keeps out the cold, light and heat in summer. February 16, 2012
Rated 5.0 out of 5.0 by Easy to work with and effective Received two 100' rolls right on time and began to insulate the pony walls and south wall in my attic. The product went up very easy and after my first wall I found it much easier to measure and cut first before installing. Cuts very easily with a straight edge and a sharp utility knife. I can already feel the difference in the attic temp. I saved over $1,000 doing this myself and it only took me four hours. May 16, 2011
