Metal buildings are great for many application from businesses to hobbies. For example, backyard sheds, garages, mini storage units, airplane hangars, and giant poultry barns are all are employed in diverse uses across a wide range of prices. However, most buildings share the same complaints: they’re uncomfortable because they get too hot (or rippin cold) and they “sweat” (condensation problems) regularly.

As an industry expert, I consistently ran into the problem of not being able to recommend a single product to solve these common issues. So, I set out to come up with a high-quality solution to this age-old problem, and after lots of research and design, I’m proud to introduce you to a new line of foil/foam products called BlueTex™ Insulation.

Designing the Perfect Metal Building Insulation

I started AtticFoil.com in 2006 for residential attics and decided to make superior radiant barrier products. Even though I designed it with residential use, there was no reason it couldn’t be used in commercial applications. I started to hear back from customers saying they were able to keep their metal buildings cooler with great results. However, my cold-climate customers had additional challenges of controlling moisture problems in the winter.

The key to controlling moisture is to keep the interior surface temperature above the dew point. This is most often done with a little bit of insulation and while there are some other products out there, I just never felt comfortable putting my approval on them because I consistently found that most of them were cheap junk that fell apart in a few years time. So I set out to make my own.

BlueTex™ is the best of two worlds, combining premium aluminum foil with high-quality EPE & XPE foam cores to work as a durable, all-in-one insulation for any metal building, new or existing. After talking to numerous dealers about installation preferences, I also designed it with a tape tabbed edge so it’s easy to install, and made it washable, so you can clean it up if you’re using it in a professional setting. BlueTex™ comes in two grades: Pro and Supreme.

BlueTex™ Pro

BlueTex™ Pro is a good choice for heat rejection and some minor moisture control. The product is a 3mm EPE foam with a diamond aluminum foil on one side, and a white tearproof PE woven fabric on the other side. The roll is finished with a 1.5″ tab with a 1″ wide peel-and-stick tape edge to make installation simple and easy.

Roll size: 500 sq ft each (4′ x 125′), 15″ in diameter
Roll weight: 25lb each

BlueTex™ Pro 3mm Foil/White

BlueTex™ Supreme

BlueTex™ Supreme is the choice for heat rejection and maximum moisture control. The product is a 6mm XPE XPE fire-resistant foam and it comes in two styles, depending on your preference: a double-sided foil/foam and the popular foil/white/foam style.

Foil/Foil Supreme

BlueTex™ Supreme in the foil/foil style is a 6mm XPE fire-resistant foam with a reinforced diamond aluminum foil on both sides. The roll is finished with a 2.5″ tab with a 2″ wide peel-and-stick tape edge to make installation simple and easy.

Roll size: 300 sq ft each (4′ x 75′), 16″ in diameter
Roll weight: 27lb each

BlueTex™ Supreme 6mm Foil/Foil

Foil/White Supreme

BlueTex™ Supreme in the foil/white style is a 6mm XPE fire-resistant foam with a reinforced diamond aluminum foil on one side, and a white tearproof PE woven fabric on the other side. The roll is finished with a 2.5″ tab with a 2″ wide peel-and-stick tape edge to make installation simple and easy.

Roll size: 300 sq ft each (4′ x 75′), 16″ in diameter
Roll weight: 25lb each

BlueTex™ Supreme 6mm Foil/White

Whether you are just looking to reflect heat and keep the building cooler from the heat (or warmer in winter), or you need a product to provide full moisture and condensation control, we have the right product for your application. Check it out at www.BlueTexInsulation.com.

If you’ve ever been told that foil works if you put it under shingles, this video is for you.

This myth (and bad practice) has been around forever and I’m finally taking it head on once and for all. Trust me, no one would be happier if it were true, but unfortunately it’s not. Radiant barrier simply won’t work directly under shingles and I’m going to tell you and *show you* why.

In this video I’ll compare 2 traditional roofing underlayments, a bare deck and RoofingFoil™ + Underlayment on a hot roof.

If your roof system has an air gap (shingles on a double-deck system, metal on battens, tile, etc) then a radiant barrier can definitely work for you. To learn more about the thermal proof of just how good it works when installed properly, check out this video: https://youtu.be/TdPLmbkhH2o

You may have been told that a traditional underlayment is all you need under your roof but this video proves that adding a radiant barrier barrier under a roof (as long as you have that air gap!) will stop the heat from ever entering your roof deck or your home below.

Watch me use thermal imaging to show you just how much heat RoofingFoil™ reflects off a standard OSB roof deck. In my final results you can see for yourself how much cooler a deck with RoofingFoil™ can be.

How to Install RoofingFoil™ + Underlayment in a metal or tile roof: https://roofingfoil.com/how-to-install/

Traditional roofing underlayments work to help keep your roofing deck and anything below it dry and free of moisture. RoofingFoil™ + Underlayment performs just like a traditional underlayment and meets or exceeds all of Miami-Dade County’s requirements for one. We’ve added a layer of our best-selling pure aluminum to the second side of this non-woven underlayment so when it’s installed in roof systems with an air space, it can block 97% of radiant barrier. This foil insulation plus underlayment is all you need!

It’s here! RoofingFoil™ is an all-in-one roofing underlayment and radiant barrier for use in roofing that has an air space. This underlayment goes great under metal, tile, slate, standing seam, and other metal and tile roofing systems that are either on a batten system or have a naturally occuring air space between the tile and the deck. Now you can seal and protect your roof all in one step with this underlayment.

As I talk about on the AtticFoil® site, adding a radiant barrier inside your attic can usually REDUCE the possibility of ice damming.

Ice damming is caused when the top of the roof warms above the freezing point the the lower part of the roof is below freezing. When this happens, the icy roof water melts and that water trickles down and refreezes at the edge of the roof where it’s cold. The roof gets warm due to warm air leakage into the attic from the home or from duct work inside the attic space.The roof can also warm up if the sun comes out that day. A roof with snow can get hit by the sunlight, which warms up the roof and begins the melting process. By the time the sun sets, and the temps drop again, that watery edge can re-freeze, creating ice dams and icicles.

The Key to preventing ice dams

To prevent ice damming, you want a COLD roof. The roof gets warm due to warm air leakage into the attic AND from the home emitting radiant heat. A radiant barrier will help keep the radiant heat emitting from the home from hitting the roof. The result is a COLDER roof deck which will reduce ice damming. Many customers have seen a significant reduction in ice damming after installing AtticFoil radiant barrier. I would also suggest checking to make sure you have good attic ventilation. Cold air entering the attic will also help keep the roof COLD.

Fix Ice dams now!

Now you know what ice dams are and how to prevent them, but what if you’re dealing with them right now? Not to worry, I have some tips that can help you fix the problem and keep ice dams at bay.


Ventilation helps your attic stay cool by funneling cold air from outside through the attic space and out somewhere near the upper third of the roofline. Ventilation keeps the air temp in the attic cold, and it helps dry up condensation or moisture.

Air Sealing

Air can easily leak out of ceiling penetrations (think ceiling fans, can/recessed lighting, vents, etc.) and into the attic space. Make a plan to go up into the attic, revel these areas and then work to seal them up. A small can of spray foam can go a long way toward sealing up cracks and spaces in these areas.

Radiant Barrier

Many customers have seen a significant reduction in ice damming after installing AtticFoil™ radiant barrier. Whether you’re stapling the foil up on the rafters or using the SuperPerf™ that was designed to go on top of the attic insulation on the attic floor in cold climates, you’re helping keep heat in the house and off the roofline.

For an attic with ductwork or HVAC/furnace equipment in the attic, a staple-up method is your best bet. Staple the foil up everywhere under the rafters. If you live in a mixed climate and would also like the benefit of helping keep the heat in during the cold months, go ahead and do a second layer of foil by adding SuperPerf™ on the floor over your insulation everywhere else. If your attic is empty of ducts or HVAC stuff, then you can just do the one layer of SuperPerf™ on the floor. Click here to see how to install AtticFoil ™ SuperPerf™ for cold or mixed climates.

Final Thoughts

Ice dams happen because your roof temps fluctuate between warm and cold. If you can keep your roof deck constant and equal to ambient (outside) air temperatures, you can greatly reduce the chance of ice dams forming on your roofline. The easiest way to do this is by adding a radiant barrier in the attic space. If you want to do more, consider checking for proper attic ventilation and well-sealed ductwork. All of these combined will help you eliminate the problem of ice dams forming on your home.

There’s a lot of misinformation about attic ventilation, so we wanted to take a moment to clear up any confusion about how you should be venting an attic and what you need to do it right.

1. If I have roof vents, I have ventilation.

If only it were that simple! Attic ventilation should have a balanced amount of both air coming in to the attic and air exiting the attic. (It’s ok if you have a little more air coming in than you do going out. For example, lots of soffit venting.) The main way air enters attics is via soffit venting. These vents allow cool, dry air to enter the attic at its lowest point and as air travels up and out the higher points (ridge, turbine, gables) so that the airflow removes warm, moist air from inside the attic. For exhaust you can have a ridge vent, a static roof vent, a turbine (whirly bird) vent or gable vents. Some people have powered attic fans or solar fans, and those are ok too. Just beware of mixing passive and active venting in an attic – that’s a bad idea!

2. More ventilation is always better.

Too much of a good thing can be a bad thing. I recommend you choose one type of exhaust vent and go with it. Ventilation is simple because air always travels the path of least resistance. When you mix exhaust vents on a roofline, the strongest vent will overpower any passive venting and then pull air in from any nearby exhaust vents! This disrupts the normal path of of air coming in the bottom and out the top and defeats the whole purpose of having low/high vents.

So while it’s generally a great idea to have plenty of soffit vents for intake, having too many exhaust vents or mixing exhaust vents can counteract your goal of cooling the attic air temperature.

3. The best way to get air moving in an attic is by using powered vents.

This idea flows from the one above and I’d just like to reiterate that a passive ventilation system will work just as well (and for free) as a powered (active) ventilation system. You’ve heard me say that I don’t typically recommend the use of any sort of powered fans and the top reasons why I feel that way, besides that they work just as well as passive vents, is because of 1) cost, 2) noise, and 3) some only work on sunny days!
Many people may not realize that it’s usually fairly breezy at the top of a roof. Standing down on ground level, you’re blocked by fencing, homes, etc but up top without obstructions, there’s a good amount of air flow. Just a little breeze moving can turn wind turbines and allow them to effortlessly pull out as much air as an electric fan can.
What if you already have fans? Not to worry! Again, fans work and won’t be a problem as long as you feed the fans with plenty of intake air. So take some time and check on your soffit vents. If they’re not cut out, get them cut out. If they’re blocked, clear the path and maybe install some baffle vents. If they’re dirty, clean them! Dirty soffit vents are actually the leading cause of attic ventilation problems and so much so that I made a video to help show you how you can clean them yourself and get things back on track with airflow in the attic.
Don’t neglect giving the fans a source of intake because without it, the air in your attic will depressurize and it’s likely going to result in air from inside your home getting pulled into the attic space via light fixtures or other ceiling penetrations. The net result is that your home feels warmer faster, and your air conditioner has work harder than ever just to try to keep things comfortable (ie. huge energy waster!).

Introducing our exclusive new radiant barrier tape and white tape from AtticFoil®!

This image is watermarked, actual products do not have any markings/stamps on them.

Do you have a project that needs a patch job? Maybe an attic installation where you are joining together two large pieces? Do you want to put foil up in your metal shed easily? Then our new AtticFoil® tapes might be what you’re looking for! Air conditioning professionals, general contractors, and handymen will love this tape too because it’s as strong as it gets.

Our tapes are just as strong as our foil products – they’re virtually impossible to tear! The rolls are 2 inches wide and run 164 feet in length. You can choose from a classic foil tape or a clean white finish tape. Both styles coordinate with our 2 best selling styles: Original AtticFoil® and AtticFoil® + White.

Simply unroll the length you need, cut it off the roll with scissors and peel off the backing to reveal the adhesive side. This adhesive is super strong and will stand up over time to heat, wind, and other normal circumstances.

To find out more information about our tapes, or any of our other radiant barrier products, check out our products page on AtticFoil.com.

Original AtticFoil® is an amazing product – it blocks over 97% of radiant heat, it’s tear-proof and it is heavyweight and easy to use. Many of our customers install the foil by stapling it up under the roof rafters, creating a sort of ceiling. This is most common in Souther states where air conditioning ductwork is typically installed in the attic. This method is great for reducing radiant heat gain into the attic in hot climates.

However, we also have many customers in cold or mixed climates that were looking for benefits from our foil both in the hot summer and the cold winter. The solution to a climate zone like this is to lay the foil on top of the insulation (as long as the attic space doesn’t have any HVAC components or tons of storage, otherwise a hybrid method would be best). The over-insulation install method allows the foil to still block radiant heat coming off the roof in the hot months but it also keeps the insulation warm in the cold months, making the home stay more comfortable and energy efficient.

Although the original AtticFoil® does a great job of allowing moisture to pass through its micro-perforations, there are some circumstances where the moisture level could be exceptionally high and water could get trapped. Keep in mind that this is a rare occurrence; however, the FEAR of trapping moisture has caused many people to be hesitant about installing a radiant barrier directly over their insulation in cold or mixed climates. SuperPerf™ is a customer driven product; we had many customers tell us, “I want to install a radiant barrier, but how will I KNOW it won’t trap moisture?” Unfortunately, every home and circumstance is different and we just couldn’t make that promise with our original product.


With that in mind, we developed an exclusive foil barrier product that not only offers the same reflectivity (97%) as our original foil, but it also offers the added peace of mind of not trapping moisture. We call this product SuperPerf™ because it has larger perforations than our original.


Whereas the original AtticFoil® is micro-perforated (done with tiny pin-holes – seen on the left of this photo), the SuperPerf™ is punch-perforated, meaning an actual piece of the foil (quite small) is punched out and removed (seen on the right side of the photo). This is just like the idea of using a tiny hole-punch on a piece of paper. The result is an extremely breathable radiant barrier foil that still offers you great coverage and protection from radiant heat gain/loss.


If moisture concerns were keeping you from looking more seriously in to adding a radiant barrier on top of your existing attic insulation, I encourage you to give the new SuperPerf™ a try. I’m confident you’ll feel good about using a product that was specifically designed with cold climates in mind by a trusted leader in the radiant barrier industry. If you have any questions about the new SuperPerf™ or if you’d like to get your hands on a sample of it, feel free to contact us or request our sample packet online.


If you have a special application or project in mind and want some advice on how to incorporate a radiant barrier – send me an email! Until then, stay comfortable out there…

Due to an overwhelming response in using our radiant barrier foil in roofing applications, we now have a new website for all roof-related applications of our radiant barrier foil: www.RoofingFoil.com.


RoofingFoil™ is the same strong, quality, tear-proof material that we have always offered and it works under any metal or tile roofing system as long as there is an air gap one one side of the foil. This means your standing seam metal roofs, your tile roofs that sit on batten systems or curved tiles, and any other brand that incorporates an air gap is a perfect application for RoofingFoil™! Make your Garard or Decra steel roof an energy efficient COOL ROOF! Regardless of what type of metal or tile you choose, including color, the radiant barrier will REFLECT 97% of the radiant heat from the sun from getting through the roof and into the home. No other product on the market can offer these kinds of proven results.
