radiant barrier paint ceramic additive indoor outdoor insulation save energy bills reflects suns rays KoolCoat

Dear KoolCoat,
I live in Austin, TX and in the summer my garage would be unbearably hot, very difficult to spend any amount of time. I ordered a 5 Gallon Kit from you ( I e-mailed you previously asking for instructions of mixing smaller amounts ). My original plan was to paint the Attic (another place that is very hot for most of the year). But those plans where put on hold for a few weeks. I read on your website that painting the Garage door would lower the temperature up to 20 Degrees, and since it seemed like a small enough job I decided to try that this weekend.

I mixed half a gallon of Latex Paint with KoolCoat and proceeded to paint the interior of the Garage Door (I applied 2 coats in less then 2 hours using a brush) in the morning. In the afternoon when I went to the garage and I could not believe how cool the garage was. Normally the garage feels much hotter than the outside temperature but now the garage feels cool. I called my wife in to the garage, she thought I called her to show her my handy work with the door, she walked into the garage asking what I wanted to show her, after a couple of seconds she looked around realized she was in the garage and started yelling "The garage is not HOT, The garage is not HOT!!!"

Austin has been the 90's for the past few Days (and it is only April) but the garage has remained in the 70's. This product has already exceeded my expectations.

Dear Koolcoat,
I have a five year old home in San Antonio, Texas and wanted to try and reduce my summer cooling bills. I bought the Koolcoat Ten kit and had a contractor spray the underside of my roof with ten gallons of inexpensive white latex paint. We haven't had any 100-degree days yet but so far my air conditioner runs less at the same thermostat setting and the total kilowatt-hours of electricity used last month are less than this time last year. The whole project cost me just under $500 and based on last month's electric bill the Koolcoat will pay for itself before this summer is over. Thanks for a great product. Margaret S.

Dear Sirs,
Three years ago we bought an older home outside Corpus Christi, Texas and last fall decided to do some interior painting. A friend suggested mixing in some Koolcoat. We bought enough for 15 gallons of paint and got busy. Over the winter we noticed a decrease in our monthly electrical usage. Rising fuel costs have increased the overall price of power but with our usage down the monthly bills are comparable to the bills of previous years. Later this year I am planning to find a good elastomeric roof paint, put some Koolcoat in it and mop it over my composition shingles to have a super reflective roof. After checking prices of paints sold with ceramic radiant barrier already mixed together, I found that by buying your Koolcoat and mixing it myself (in paint that I chose) I saved over $10 per gallon compared to the pre-mixed. Respectfully, Tommy Vaughn

Mr. Koolcoat,
I thought I'd let you know how well my project came out. If you can remember, I e-mailed you about trying to take some of the heat out of my barns. I have several various sized barns sheathed in corrugated steel, with no insulation, and in the summer the inside temperature was almost unbearable. You told me to power wash the outside walls and roof, find a good white acrylic flex roof paint add Koolcoat and spray on two coats. I followed your directions, and during the past two summers the barns have been pleasant to work in. Now that I know this reflective thing works, I'm planning to paint Koolcoat all over my house. You have a good product and it is easy to use! Thank You, J.C. Garza

Dear sirs,
I just want you and others to know that KOOLCOAT is a remarkable product.

Our outside temperature went to 110 degrees this month, July, and the insulating properties of KOOLCOAT in our paint has kept our two story addition feeling comfortable without the air conditioner going all the time.

The inside walls actually feel cool! Always in the past, it would become unbearable in the addition even in the low 90's. We are getting nice comments about how nice the paint job looks as well. I guess you know I'm pleased with the product as well as the great service you provided. Thank you. Herb A. Pasco, Washington

We bought a new house in North San Antonio in March. I had done alot of research on radiant barriers and after several months of checking them all out, decided yours would be the best alternative. Our house is 2500 square feet with a large attic. Yours being a spray on application was perfect, with the high ceilings in the attic.

I tested the temperature for one week prior to installing just one coat of the KoolCoat. Average outside temps were 96 degrees, average attic temp at 5 pm was 142 degrees and my AC was running average of 7 hours a day.

I installed the first coat on a Friday and started testing the attic temps again for a week. The average attic temp fell to 116 degrees, 26 degrees cooler and the AC went from averaging 7 hours a day to 3.5 per day.

I can just imagine what the second coat, which I have decided can wait untill the weather cools off, will do.

I can't say enough about your product, not only the results, but the ease of application also. You customer service was top notch also. Who else would make the delivery arrangements you did!

Thanks again, and look forward to dealing with you in the future. Tony Bell

I purchased your product last year. I applied it with an elastomeric coating on the metal roof of my 24 foot motorhome. What a difference in the summertime. Prior to the application during 100 degree Texas days, the air conditioning unit would only cool the motorhome to 80 degrees and run continually. After the application of Koolcoat, I can maintain the temperature at 70 degrees during the hottest days.

I applied Koolcoat in a light colored latex paint to the inside and outside of my garage door. I noticed a significant difference in the temperature in the garage this winter.I have used my kerosene heater a lot less this winter when working out there.

I have painted my living room and master bedroom with your product added to the paint and am totally satisfied with the results.

I plan on painting the rest of the rooms in my house using your product in the coming month and will paint my roof decking this fall when the temperature permits.

I am 100 percent satisfied with your product and your customer service. Sincerely, Scott Nelson, Wichita Falls, TX

I live in the Dallas area where the summer heat gets very intense. My home has a three-car garage with a game room, and a bedroom directly above the garage. During the summer months the rooms above the garage stay
unbearably hot even with ceiling fans, and the air conditioning running constantly.

In trying to find a way to keep these room cool, and cut down on my electric bill, I came across your website. Being skeptical that it would work, I only purchased a one-gallon kit, and thought I would start by only painting the inside of the garage door. Due to the heat, I waited until 11pm to start painting. The inside garage temperature was 95 degrees when I started. By the time I finished the first coat the temperature was down to 85 degrees. I could not believe it. I was only halfway finished with the first coat, when my wife stepped in to see make sure I hadn't passed out due to the heat. She said, "I am not sure if this is only mental, but it already feels cooler in here." We were both amazed what a difference it had made with only one coat. The next morning I put on the second coat. Now the game room, and the bedroom upstairs are as cool as the rest of the house. Before KoolCoat we kept the thermostat at 76 degrees, and the house (especially the two rooms) were still hot. After two coats of KoolCoat (only on the garage door), we set the thermostat at 79 degrees, and all of the rooms are comfortable to us. I am placing another order so I can finish the job I started. I can't wait to paint the ceiling and all of the walls of the garage so that we can feel even more of a temperature difference.

Now that I have proved to myself that this product DOES work, I am already planning on painting other rooms in my home, as well as the attic once the winter months arrive.

Just wanted to say thanks for getting the Koolcoat sent out so fast which allowed me to apply it on Memorial Day. I just wanted to share with you my screw ups which in the end turned out OK. First problem was that I rented instead of buying an airless sprayer. Lowes told me that they had one which had a .030 tip which was what I wanted. Well I waited until late Sunday afternoon and it was gone. I then went to Home Depot who had a new one that had never been used. Problem was is the tip size was a 517. I had no choice so I went ahead and rented it. The guy told me it had two filters , one on the machine and one in the spray gun handle. When I got home I removed the one from the gun. I had thought he told me that the other filter was in the actual suction tube but when I pulled it apart there was nothing there. I figured the guy didn't know what he was talking about and proceeded forward. I stared about 8 am and finished up around 11:30 am which was good because it had become extremely hot. After I got the thing outside to clean and turned it over I noticed a cylinder up underneath the machine. As I unscrewed the thing I was thinking I had done all of that work for nothing. To my suprise the filter was not all that clogged and only had small amounts of the Koalcoat on it and there was a small amount on the inside walls of the tube assembly. There really couldn't have been that much in there anyway as the filter is not all that big. I guess that it was able to go through this larger filter OK. The spray gun did clog around 6 to 8 times but that didn't take 2 seconds to clear. Before I had finished and started to clean up it was becoming very hot in the attic and I was beginning to wonder why. It had been raining when I started and was not all that hot. Little did I know that the sun had come out around 10am and started to heat things up. Around 2 pm I put a wireless transmitter I have in the attic approx. 12 inches from the roof. The temp read 102 deg. The actual temp outside at that time was 92 deg. resulting in only a 10 deg differance. I hope to do more testing in the future as soon as all of this rain clears out of here. Thanks again and I will be ordering more in the future to spray the exterior of the house.

Sounds like you had a "memorable" Memorial Day! I am very surprised you were able to use the 517 tip (that is .017", and Koolcoat diameters are .002" to .008") without more clogs. Six or eight clog-ups are a bit unreasonable, but it sounds like you had overall success. The temperature readings are about right, I don't know how your attic is ventilated, but 102 in the attic on a 92 degree day isn't bad. Normally "an attic" will be 50 degrees hotter than ambient. I don't know why more builders here in the South can't learn to build attics that ventilate better. There is a formula of soffit vent area compared to ridge vent area that will, if followed, convect air through an attic at such a fast rate the air has very little time to heat up. But I see so many houses without proper vents. Builders will put in plenty of soffit vents and then stick a couple of the metal vent caps on top. Until you've experienced a ridge vent, one cannot imagine the amount of air that can be moved. Couple good ventilation with a coating of Koolcoat and an attic can be cooled down almost to ambient. Keep me informed about your temperature testing.

Your email was a great rendition of some of the things that can go wrong and your ways of overcoming them are enlightening. What I'd like to do is put your email into my testimonials on the web site, so others could read it and know that they aren't alone. It may even help some people work their way out of some problems they can't figure out. I won't use your name, if that's ok, and I probably will preface your email with an explanation about why it was written. Whatcha think?

I believe my attic is well ventilated as it has 35 soffit vents. The problem was that there was only one ridge vent at the top about 8ft. long. If you use the formula I didn't have enough vent on top. A couple of years ago I added 3 of the 1ft. by 1ft. caps and put them as close to the ridge vent as possible. From what I've learned if you don't you can cause it to short cycle thus pulling air only between the caps and the ridge vent. I'm probably going to add 2 more of the caps to get the appropiate area needed for ventilation. As far as the clogging I would know it was about to happen because the spray gun would start this loud cracking and popping noise like popcorn and then it would clog. I would simply reverse the tip and spray a couple of seconds that way to clear it. Overall it went good. I just wish I would have come across your site last winter instead of May. I do feel though that I didn't want to go through another whole summer without the Koolcoat applied. I can give you more updates on my temp. readings throughout the week if you like so that you can post on your website. Like I mentioned before the receiver is in my downstairs kitchen so I can toggle back and forth to watch the outside temp and the attic temp. Thanks again.

P.S. I was just in the process of taking a reading. It looks as if my temp differance of 10 deg. between attic and outside was a one day deal. The average this week has been around 24 deg. hotter in the attic. Right this moment it is 95 deg. outside and 118 deg. in the attic. I would still say that is good. I still believe I need more attic ventilation to pull the heat out. I have two 12 in. by 12 in. fans that came out of a large control cabinet that I am going to experiment with this evening by placing them onto the bottom of the 1 by 1 ft. caps I installed. I am going to tie them into my x-10 controls and have them come on say around 3 or 4 in the afternoon and run into the late evening. I figure maybe this will get some flow going and suck out some more heat. I think installing the large attic ventilators waste energy and can pull cool air from inside your house if your not careful. These small ones might be good enough to get it flowing. Thank you for the e-mails being answered quickly and efficiently. I'll keep you posted about the temp average as it will be getting hotter. Thanks

Now “this house” 1920’s Historic Bungalow (frame, single pane windows, pier & beam floors, NO & I mean NO insulation).

I first sprayed the attic, and noticed an immediate affect. I then painted the exterior just as Chuck suggested, using BIN primer, 2 coats of good latex paint. ( I used Kelly Moore Gloss latex-excellent coverage).

I’m having to turn the thermostat UP in the summer, 1 night I had to get out an extra blanket.

I switched utility companies so I am not sure when I will get a true dollar energy saving amount, although for me a "comfort saving” is more important than the dollar figure.

Thanks to Koolcoat & Chuck for all his advice. I know I must have worn him out with all my questions!!!
