The product is not an insulator it is a reflective barrier. As you know heat moves three ways Radiation, Conduction and Convection. This product almost eliminates radiation. I installed this in a steel hanger in Glendale AZ.

Answer: 
Yes, the radiant barrier is easy to cut with regular scissors and it has small squares divided by straight lines, so just cut right on the line. Very light-weight and excellent quality.

Rated 4.0 out of 5 by 20 reviewers.
Rated 5.0 out of 5.0 by good heat-reducing product for existing home Our neighbor was the first to install the Enerflex radiant barrier by himself. Observing and finding it very easy to install especially with 2 people we also purchased enough for our attic when it was on sale. We're all in our 60's. Walking out from under a 20 span we'd completed, I could feel the difference in the temperature. I just went up in the attic to snap the photos, yeah it's hot up there, this is Florida, but the heat wasn't blasting down the attic stairs as in the past so I expect a minor drop in the electric bill. Most beams were right on 24inches. A few needed some stapling. Not that I'd install it for this reason, but from a woman's point of view it does look more finished. June 21, 2013
Rated 5.0 out of 5.0 by Easy to install. You can feel the difference immediately. I first tried to install it using staple gun but quickly realized the the advertised method was better. There are steel rods inside that work like a spring and fix those panels. So, after about 15 minutes I had them in place. I am buying more to complete my roof. You need to be careful not to tear them in areas where those rods penetrate the plastic. February 7, 2016
Rated 1.0 out of 5.0 by Terrible product, inferior to alternatives This is the worst radiant barrier product I have worked with. The panels lack reinforcing on the long axis. The film tears very easily. There are cheaper and better options that have rip-stop or tough material. Get a roll of radiant barrier and cut it with scissors or utility knife and staple it on. Faster and does a better job. December 6, 2015
Rated 4.0 out of 5.0 by very good product this product was as easy to install as was advertised. August 25, 2015
Rated 5.0 out of 5.0 by Great Value on this Radiant Barrier for my Garage Door I purchased this as a "daily special" from Home Depot. Installation was easy but I had to hand cut for my panels on the 16 foot Garage Door and used 3M double sided tape to attach here. Works great especially since my door faces South so I get lots of Sun & heat here. This was a great value since this was discounted as a daily special and I will purchase again if I see this on special for my new Garage going up now. Thanks Home Depot! June 16, 2015
Rated 2.0 out of 5.0 by Works in limited application This radiant barrier is very hard to cut because of the heavy wires that run through it. It can't be done with a utility knife but requires a clipper of some sort. If your job conforms perfectly to the 2 x 4 FT. panel size then you might have a good thing going but if there is any cutting and fitting to be done I would stay away from this product. The mylar film does tear too, which is not good. I did not find this product to be user friendly. May 26, 2015
Rated 3.0 out of 5.0 by No significant difference in temp Easy enough to install but I've not seen a significant difference in the temperature. Still really hot in the attic. July 27, 2015
Rated 5.0 out of 5.0 by Smart Purchase Went up easy, made a difference on heat buildup in the attic. July 7, 2015
