summers are HOT in Sacramento CA. We get many 100 degree days plus some of these
days are back to back. I really was tired on not having a house that was
comfortable and having "HIGH" electric bills. I had thought my only solution
would be to upgrade to a high efficient system ($$$) and spend lots more ($$$)
on traditional attic insulation.
I often have thought how I could modify or retrofit my house
to make it become much more energy efficient without breaking the bank. I was
never satisfied with the solutions and costs.
I've been an HVAC tech for over 24 years. My house is an
older single story with very little attic insulation and a darker colored roof.
I have a 14 year old split gas electric heating and cooling system. I do have it
tuned up and running at optimal performance for its age with a couple of
enhancements. I did add to 2 attic fans before installing Radiant Guard, which
did not help even setting them low to 85 to cycle on.
Before my Radiant Guard installation my older A/C system
would run almost non-stop from 10:00am to 11:30pm if I set the thermostat to 75
on 100+ days. The temp inside would gradually increase to 81-83 through the day
depending how much over a 100 it could be that day. These are my results, yours
After the Radiant Guard installation my system won't usually
come on until noon or sometimes even after 1:00pm and now cycles at least 20-35
minutes every hour I run it even if I set my indoor temperature at 76 degrees on
a 100 degree day. It will hold my house at that indoor temperature, just
After that I experimented on the next HOT day (108) and set
my indoor temp to 72 in the morning to see if it could do maintain that
temperature with this product and it held it all day. That's 36 degrees
difference from inside to outside, Amazing!!! There were a couple hours were it
ran non-stop, but still I used less electricity that day compared to before
Radiant Guard was installed on a similar day and outdoor temperature scenario.
Did I say that's Amazing!!!
I also noticed something very different after I installed
Radiant Guard which had to do with my indoor night time temperature swing. After
running the indoor temperate down to 70 degrees, (I like it nice and cool for
sleeping) my unit would cycle off for the night and in the morning my thermostat
would read only a drop 1 to 2 degrees cooler than 70 on which it was set at.
Outdoor temperatures at night might drop to the high 50's sometimes or in the
low 60's in the summer usually. This tells me that this product should work well
this coming winter. My attic temperatures are lower now and my attic cools off
I've had this product installed for over 3 1/2 months now.
These are my electric bill results. First month, April was 26% savings compared
to last year same month. Second month, May was 29% savings compared to last year
same month. The third month, June to was the shocker, 48% savings based on same
month last year, WOW!!! My house now feels like a home to me. I get up in the
mornings smiling now knowing my house has the (RGA) Radiant Guard Advantage and
will keep me and my family comfortable on the hottest summer days.
It is my opinion that I could have spent thousands adding two
layers of R39 attic insulation and even more on a newer high efficiency central
heat and air conditioning system and would "have not" gotten the same
performance to price result that Radiant Guard has given me with my old system.
I will upgrade my HVAC system someday. I do not know of any another product that
could have this performance to price comparison. Just Amazing!!! I would highly
recommend it. I'm very satisfied now!
Why did I pick Radiant Guard? They listed the pricing up
front on there site. Reasonable shipping cost for the weight and size of
material. Also, the customer feedback that had been left on the site. A flawless
transaction for me...
Just to let you know, I installed you product on top the
attic insulation, and noticed an immediate drop in temperature on the second
floor of my townhouse which I have never been able to cool properly.
I am very pleased with you product, and have told others of
how well this simple inexpensive product work.
I hope you notice an increase in business in the Buffalo N.Y.
Orchard Park, NY
Wanted to let you know that I installed this over the 4th of
July weekend and it has already paid for itself I think!!!!
What a wondrously "forgiving" product... though not intended
to be a one-man job, I managed to cut, handle, install by myself while my family
was away on vacation, and the benefits were immediately apparent.
I AM a believer in its value, and as an architect will
encourage others to use and benefit as have I. Thanks!
I just purchased three rolls of Ultima radiant barrier a
couple months ago, and I just wanted to let you know how happy I am with the
product. We installed it on the undersides of our rafters, and we started a bit
late in the year, so we were unable to completely finish the job yet. We just
paid our first real summer electric bill and it was 40% lower than last year at
the same time. Within two months we will have paid for the radiant barrier. It
was very well made and easy to work with, your price was very competitive, and I
could not be happier. Thank you very much.
Fort Worth, Texas
I have a brick veneer office building with a metal roof. I
have installed radiant barrier on the rafters and am about 60% finished. I have
already seen a 28.4% decrease in my daily KWH usage for the month of April when
compared to last year. Amazing. And we are not even into the worst part of
summer. The stuff works good and is easy to handle. I used the Ultima with an
electric staple gun with 1/4 inch staples. I am in College Station, Texas, and
think this product should be more widely used for energy conservation and

I am writing to tell you how wonderful your product is. It
was going to cost me app. $2,000 to have a local company come and install a
radiant layer in my attic, but after surfing the internet, I found your company.
I read my options for products and the ease of installation instructions and
decided that I could do this myself! The cost and shipping was very
I live in a 2 story house that has always been HOT on the
second floor. You could feel the temperature rise as you walked up the
stairs. Even with the ducts closed on the first floor, it was still hot.
I installed RadiantGUARD all by myself and it was very easy.
The temperature is almost the same on the second floor as on the first. My
air conditioner does not have to work as hard or as much since installing it.
I am amazed at how the difference it has made in the comfort of my house.
Can't wait to see what a difference it makes this winter, not that I am in any
hurry for it to come, but knowing my heating bill will be lower and my house
more comfortable....I will gladly promote your product to other and the ease of
installation. Thank you for having this product available to the general
public at a reasonable cost.

My wife and I
purchased a 30-yr home in Redding, CA in October of last year. We dove
right into a fairy expensive remodel, which included the addition of a 400-sq-ft
room and a full tear of the kitchen and all surface coverings and the flooring
downstairs. In short, the entire downstairs was stripped to the studs.
insulation was R-11. What's worse is that it was compacted. I
replaced all the insulation and installed RadiantGUARD radiant barrier
everywhere I could. On the floors, because they are 1.5" T&G raised, I
laid down radiant barrier and then Tyvek over the top (Hardie board is over
that, but that is off point). I put Tyvek over the vertical shear on the
addition, then shimmed out the walls 3/4". I then installed radiant
barrier before I nailed up the T-111. I also installed radiant barrier on
the bottom of the truss studs in the attic of the new addition. I was not
able to shim the existing vertical walls, because of spacing issues with the
second floor; nevertheless, I did put radiant barrier on these walls as well.
What we have at
this point is a fully insulated downstairs with radiant barrier on just about
every surface (floors, walls and attic). I am curious to see the thermal
performance this summer, but we have already had 100+ days here in Redding and
the downstairs is like living in a cooler. On the hottest day so far, 103,
this floor held at 74-degrees until 2pm without running the AC unit or nay fans.
Amazing to say the least.
We are not
tearing out the second floor drywall, or doing anything as substantial as we did
downstairs, but I will be installing Radiant Barrier in the attic, and just
about any other place I can.
So far we are amazed with how well
Radiant Barrier works, and we have told everyone that we know about it.
I’m here to sing
the praises of radiant barrier. We have lived in Oklahoma since 1973
and the summers here are sometimes beyond bearable. Several years
ago at our previous house in Bartlesville, Oklahoma the air conditioning would
run constantly during the day in the summer months and still could not bring the
inside temp below 80 degrees. Through a local contractor I was introduced
to the radiant barrier product and I must say I was skeptical at first.
But I decided I had little to lose so I bought the radiant barrier and installed
it in the attic over the loose fill insulation following the manufacture’s
recommendations. Immediately we experienced the results of my labor, (and
the radiant barrier), with lower utility costs and fewer air conditioner service
calls. The ac unit would cycle as it should, the house had become very
comfortable during the summer and there was little variance in temperature from
room to room. There was a noticeable improvement in retaining heat during
the winter months too.
Eventually we moved back to Tulsa,
Oklahoma and since that time I had been looking, off and on, for radiant barrier
to install in my current house. Recently I ran across the
RadiantGUARD website, I immediately ordered a 1000 sq foot roll and just
finished installing it in the attic. Luckily because of the recent storms
it was cooler in the attic and I was able to complete the installation within a
few hours in one day. I also had the help of a roller jig I had
constructed that made the task easier and go much faster.
As you can tell I am sold on the
benefits of radiant barrier and I take every opportunity to tell anyone who will
listen about my experiences. Some friends have installed radiant
barrier and are amazed at the results.
All I can say is WOW!! What a difference your product has
made in my home.
I live in California and the last few days have been HOT!!
While the outside temp was around 90-100, my house stay 20-25 degrees cooler
with no air! I decided to tack the Ultima under my rafters. This took some time
and effort however, it was well worth it!! I have pasted this info on to a
number of friends. So expect some orders from Northern Ca. Thanks again
We installed the product on the attic ceiling, covering all
joists, crossbeams and rafters with heavy-duty staple guns. The product is
extremely durable and easy to work with. Me and my wife built the jiq with a few
minor modifications. We used galvanized pipe and elbows with the PVC pipe for
the roller. The jig is a must and I highly recommended it. It is worth the cost
(very little I might add) in time and effort.
I have to tell you a story...My wife and I were in the attic
and we started at the peak on one end of the attic ceiling. It was approx. 125
degrees and the going was slow. As we were putting the product on the attic
roof, we noticed that on the side without the barrier, we could hardly breathe
as the temperature was excruciating. The side that we were working on was
considerably cooler. We could actually breath under the barrier side. We also
had to have our evaporator replaced in the attic as our new home had a slight
leak. I went to check on the technicians who were installing the new unit at
3:00 pm and I ask how they were doing and they said we can't believe how cool it
is up here. They stated the last two attics they were in were so hot that they
thought they were going to be sick. Prior to installing the radiant barrier, I
wanted to cool the attic down and I was thinking about the spray on barrier as I
heard someone in the neighborhood had it done. I thought I would try an attic
gable vent, so I went to the Hardware store and bought one with a thermostat. I
installed it and had to program it to turn on at 110 degrees and it continually
ran between 12:00 pm to 4:30 pm. After finding your web site as well as others,
I decided to purchase from you and I must say....Your site was the most
informative and the delivery time was unbelievably prompt. We installed the
product and the attic temperature rarely exceeds 92 degrees. The gable fan is
now worthless. Our average electric bill without the radiant barrier in April,
May, and June was $140.00. After installing the radiant barrier our electric
bills have been reduced by 50 % even in the hottest months. We also have double
pane windows, high efficiency bulbs exclusively and we keep the thermostat
between 71 and 73 degrees. Start installing in the early am and quit around the
hottest times. Resume two hours after nightfall. Drink plenty of water and Power
Aid if installing during the hot months. You will probably need a step ladder to
reach the peak if installing on the ceiling of the attic.
I have bragged about this product and your company to all
interested parties. They are skeptical until they hear my testimony. We love the
product and the results.
Installed 2500 square feet of Ultima laid on top of
pre-existing R-40 fiberglass attic insulation in my house with truss roof
construction and a metal roof. Immediately noticed a stabilization of room
temperatures and a reduction of AC usage. Radiant heat gains previously
experienced from the metal roof are finally neutralized. Am expecting similar
positive results during the upcoming heating season through improved reduction
of living area heat loss.
Quality of material-excellent
Ease of installation-despite expected truss
construction challenges, quality and forgiveness of material made
installation doable for a one man crew.
Purchase/delivery: excellent, couldn't be better.
Satisfaction level: highest I can rate.
1-Taping a piece of course grade sandpaper wrapped around
the end of a wood pole (like the kind that unscrews from some brooms/mops)
made a nice push stick to move/adjust the radiant barrier material for final
2-wearing old school soft sole shoes like the converse
Chuck Taylors enables you to feel ceiling joists for safe foot positioning.
3-for material cuts, use partially opened scissors.
4-for any area that you may later wish to gain walking
access; using foil tape, attach a piece of 3/4 PVC pipe cut the width of the
roll to the material at the start of the access point, with the opposite end
taped down with foil tape. Doing this will allow you to easily roll up that
section of material for temporary attic access. When finished, just unroll
leaving the PVC attached for future access.
Motivation: Typical home improvements offer the
homeowner reimbursements only upon the sale of the home. Insulation improvements
are unique in that the homeowner will realize monthly reimbursements in the form
of reduced power bills, and a reimbursement at the time of sale. Also, the
general feel of the house now having stabilized temperatures is very nice
Am I glad that I installed a RadiantGUARD barrier:
I purchased your premium grade Radiant Barrier on 8/16/07 and
had it installed shortly afterward. Having spent a good portion of my career as
a Quality Control supervisor, I was use to analyzing data, so I decided to
evaluate the performance as best I could of the installation of your product..
This graph shows the temperature difference with and without
a radiant barrier at various times of day during the month of August, 2007.
After reading numerous articles on how a radiant barrier can reduce summer heat
gain and winter heat loss, I decided to test the effect this had on my home. I
used wireless thermocouples so as to collect the data at one location. The
placement was: 1 - Outside facing north under a patio cover, 2 - Inside the
center of the house, 3 - In the attic under the blown in insulation and touching
the ceiling wallboard, and 4 - In the center of the attic’s framing space (hip
roof). The Radiant Barrier was laid over the existing insulation and on top of
the AC ducts. The parameter of attic flooring was tacked and mark with tape. Two
men with minimal experience took four hours to complete the job. Preliminary
indications are that the AC runs less, temperature throughout the house is much
more uniform, with no warm or cool spots which was a problem before installation
of the radiant barrier. After seeing what severe effect the sun has on the
attic, insulation, and heat infiltration, short of shade trees, a radiant
barrier does make a lot a sense. Energy usage is down 20 -25% so far.

To all who read this: This product works! I cannot begin to
express my satisfaction, near elation, about the effectiveness of this product.
I purchased the Premium Radiant Barrier to lay over my attic floor upstairs.
The current insulation is blown-in and likely the original
insulation (home built in 1976). Our upstairs bedrooms were consistently 8-10
degrees warmer (summer time cooling) than the main floor. I looked in to
purchasing a de-humidifier to help with the mugginess and temperature, but the
cost of machine and cost to operate turned me off. I found Radiant Guard through
a Google search, and I'm thrilled I purchased it.
Upon installation, the results were immediately felt. During
mid-afternoon, typically when the upstairs is hottest, I went up stairs to find
that I could not feel a difference in temperature between there and the main
I have noticed the a/c kicks on less often, though I cannot
report any utility savings at this time due to the fact I have no bills to
I'm confident there will be a savings, though the comfort
level upstairs is savings enough for me. It's the best $130.00 I've ever spent.
Thank you Radiant Guard.

I live in Cincinnati Ohio and bought the Premium barrier. I
laid it directly on the attic floor over loose fill insulation. The big surprise
to me is the difference it makes in the Winter. We turned the thermostat down
two degrees during the day and are very comfortable. We turned it down six
degrees at night and sometimes we wake up in the middle of the night because we
are too warm! One word of advice, do not skimp on the plywood platform when you
are working in the attic. I did, and put my foot through the Master bedroom
ceiling! But I have a great wife, she was only mad for about 5 minutes.
Thanks, great product!
I purchased a roll of RadiantGUARD's White Double
Bubble Insulation to put under the decking, between the rafters of my work shop.
The insulation worked out great, it is so light weight that I did not need any
help installing it even though I cut it in 10 foot lengths. Before
installing the insulation I was having a problem with moisture build up under
the decking, since installing it I have had no problems at all. The shop
stays warmer now with very little heating required.
The only thing I would suggest you check before you staple
the insulation in is the size of the staple. I started out with one that was to
long and had to change and use a shorter one.
Thanks for the great product.

RadiantGUARD was especially forthcoming in answering
questions by email and telephone. Customer Support was especially patient and
helpful. The double foil insulation I ordered arrived in a timely manner,
with five day (because of a weekend), and was what I was promised. The
installation of the 48" x 125' rolls went well. My installation was in a
crawlspace, and I chose to leave the water and gas lines exposed, so there was a
little more work involved. I should mention that I live in coastal SC, where
there are no basements. I have no installation recommendations other than
those supplied by RadiantGUARD. Patience is the key!
RadiantGUARD has made this is very positive experience
for me. I am 65 years old and had no trouble with installation.
RadiantGUARD's website exemplifies the perfect model
of online purchasing that eludes the vast majority of it's internet
contemporaries. Aesthetically perfect blend of refreshing clarity, understated
strength, and %100 functionality blend seamlessly, affording fortunate clients a
precision buying experience, from start to finish that's second to none! The
product I ordered arrived with astounding speed and in perfect condition despite
UPS destructive efforts. If only RadiantGUARD's business approach were
the world wide STANDARD for internet merchants. Not only would individual
consumers benefit dramatically But I venture to speculate economic
revitalization nationally as well as globally and extending nobility into the
atomic structure of humanity itself! Thank you RadiantGUARD!!!!!!!!!
This has got to be the best business we have ever dealt with,
In May of this year I got up in the attic with a friend and
we installed the Standard radiant barrier insulation purchased from you all. I
was impressed with the thickness of the product. It was so much more
'substantial' than the product we had previously installed. Our utility
bill has lowered an average of 600 kilowatt hours each month for the last 3
Port Charlotte, FL
Just received your product yesterday. By the way, your
customer service, with the updates of emails regarding the status of the order
Hi; I just want to say it has been a pleasure doing
business with such a service oriented company as you guys are. I received my
order with out a hitch. You have revived my faith in the Internet.
We decided to install a radiant heat barrier, based
on what we read on both commercial and government web sites. I ordered the
medium weight barrier from the RadiantGUARD
I had assumed the radiant barrier would have to be babied
going up, and would be easy to tear. Actually it is just the opposite.
It is quite rugged and survives rolling, folding, and minor accidents with blunt
objects, all of which got thoroughly tested as I fat-fingered my way through the
job. I trusted the web-sites that a radiant barrier was a good idea, but
as you're installing it, it's hard to believe it is actually doing anything for
your house. The whole thing is kind of theoretical, or was until I got
near the center. I was finally able to sit in a stooped position and I
noticed how hot my face and head felt. It was like I had sunburn.
Then I sat back and the heat went away! It was just the "shadow" of the
foil barrier. As I moved under I felt fine, as I moved out from under, I
was distinctly hot and uncomfortable. This through the asphalt shingles
and 1x6 roof sheathing! It was obvious that the thin layer of foil was
making a huge difference in the amount of heat coming in through the roof.
It was like being hit by a heat-lamp when I wasn't under the foil.
Overall, I highly recommend a radiant barrier in any house
that does not already have it built into the roof sheathing. It was cheap,
relatively easy to install, and made a significant difference. I don't
have a full month's electric bill to compare yet, but our bill dropped by $75
with only a partial month of radiant barrier and insulation so I am looking
forward to the first full bill.

I'm sure you have good data showing the effectiveness of
RadiantGUARD, but I thought that I'd share my results with you and your
guys. You can take the engineer out of the business, but you can't take
the engineer out of the retiree. The middle grade radiant barrier was very
easy to handle and install without tearing or puncturing. After installing
2000 sq.ft. RadiantGUARD
in my attic, mostly stapled to the underside of the roof rafters, peak attic
temperatures were lowered about 11 deg. F. Corresponding electric power
usage was lower by 20% for the month of May compared to May 2005.
For maximum benefits, I made sure that ambient air vents fed both the attic
space above and below the foil, and the air space between foil and roof had
unobstructed communication with either ridge vents or mechanical ventilators.
The only thing better is to install a new roof using aluminized decking.
