Ratings & Reviews for Reflectix R- 21 Attic Wall Unfaced Reflective Roll Insulation 100-sq ft ( 48-in W x 25-ft L ) Individual pack

Measure oversized and whittle down

Excellent vehicle sunshade,,, even if I DIY

Great purchase with great results

The insulation was a bit thicker compared to competitor for the same price. I bought the insulation to install onto my RVs windows. Great investment with great results. Completely makes a big difference under this West Texas heat.

Great

I put this on my roof of my shop after adding AC, it has made a big difference with the temperature in the summer it can be 95 outside and 72 in my shop. I put it up by myself, get some help, it is a two person job.

Much cheaper than buying new windows

I cut this to fit my windows since my AC unit could not handle the extreme heat we have been having. I cut them a little larger than my windows and covered them with white tablecloths and pushed them into the inside window frame. It looks like I have white shades from the outside and my curtains cover them from the inside. Keeps my house much cooler and the AC is not strained.

Flexible

Double Sided and Flexible

Insulatation station

Good insulation - easy to use and install. Would buy again

Great Quality

Great product for keeping your shed or backyard building cooler.

Easy to work with, and no fiberglass or polyester

Ridiculously over-priced. This is essentially bubble wrap made of mylar. You know what bubble wrap costs, and you could buy enough mylar balloons at Sprawlmart to cover the same area for considerably less money, plus you'd have the helium to bottle and sell on, recouping a considerable amount of your balloon investment.

Keeps the heat out

I used this product in my RV. Easy to cut, measure and install. It reallyy cut the heat coming in windows...especially during this extreme heat wave.

Home project flexible

Easy to use, well made.

Easy to install

Excellent quality radiant barrier that is simple to install.

Buy the good stuff NOT this!

Purchased at least 15 rolls to insulate out wooden outdoor shed that we made into a feral and stray cat safe haven for the winter. It was freezing in there. We seen NO difference. Only way to get warmth is we had to purchase n outdoor heater which still was not enough. Needed 2 heaters. Electric bill sky rocketed. Hate to see if the shed was metal! Definitely invest in better insulation. Will cost much more. But this was worthless!

More than just insulation

Makes for great protective bags for packaging artwork!

Great as "primer" or under coat isnul. garage door

Used this for my garage door insulation. Easy to cut, glued it lightly to the inner surface and then added 1.25in foam board insulation cut to fit very snugly and what a difference.
