  • New Product - Therma-Dome Pull Down Attic Stair Cover

    Pull down attic stairs are great for providing easy access but they are notorious for being terrible at energy efficiency. The temperature in the attic and in the living space below differs wildly in summer and winter. This means more heat transfer, making it a critical place to insulate.

    Although there are several attic stair covers available on the market none of them perform that well. Today’s insulation packages are up to an R-49 depending on your location. Today’s attic stair cover needs to be able to insulate up to these levels.

    We are pleased to now be offering the Therma-Dome Attic Stair Cover. Therma-Dome is the most efficient attic stair cover on the market. It is reflective and on its own achieves an R-13. Capable of achieving an R-40 with the addition of Maximize-R, Therma-Dome is the ultimate in attic stair insulation.

    The unique weather-strip design and attachment ensure a good air seal. Therma-Dome comes as an easy to install kit which takes approximately 15 minutes to assemble. Click here to read more about how Therma-Dome can help you insulate your attic stairs.

  • Reusable Art Bags for Wrapping and Packaging Artwork

    Who knew? Well, actually we did know, but never knew exactly how our customers used InfraStop® bubble foil to wrap and for packaging artwork.  It’s a perfect fit really of construction grade bubble foil insulation doubling as a packaging material.

    A special thanks to our customer K.C in New York City.  We had an opportunity to speak with K.C and she explained how she uses InfraStop® for wrapping artwork.  Most importantly for this post, she explained the actual process she uses to make the art bags.  She even put together a great instruction sheet that we are giving to you with her permission.  Thank you so much K.C!

    Artists that travel to and exhibit in art shows are constantly wrapping and unwrapping their art work.  They need a bag or pouch that is sized to the specific art piece that is not too thin or too bulky and is reusable.  InfraStop® foil insulation is an excellent product for this application.  It’s flexible, easy to cut, and rugged to stand up to repeated use.  The InfraStop® art bag is also reflective so it will block the transfer of radiant heat.  This helps protect the contents.  Just think of reflective packaging material.  InfraStop® can also be used for insulating artwork as well.

    Art Bag Instruction SheetThe above pictures are the one K.C sent of her art bags as well as the instruction sheet she put together. We told her we wanted to build the bags too.  The following photo gallery is our step by step construction using her easy to use instructions for two art bags used for wrapping artwork.

    Measurements are from outside of frame to outside of frame.  The first painting measures, 23 inches wide by 19 inches tall, close to the sample in K. C’s instruction sheet.  The second picture measures 31 inches wide by 22 inches tall. We hope you enjoy the post. We had a fun time making the InfraStop® art bag.

  • Insulating 1500 Gallon Outdoor Water Tank – Customer Project in the Arizona Heat

    A big thanks to T.A for sharing a picture of his water tank insulation project.  T.A contacted us looking to insulate a 1500 gallon water tank that was purchased at Tractor Supply.  The tank sits exposed in the Arizona heat and is used for drinking water. HeInfraStop Insulation used to Insulate 1500 Gallon Outdoor Water Tankre’s the excerpt from our contact us page.

    Comment: have a 1500 gal. water tank, from tractor supply Co.  need a wrap for it to reflect the AZ sun so it will not get to hot. any suggestions?  I use it for our drinking water. Can you help me?  thanks T.A

    We recommended our InfraStop double bubble insulation in conjunction with using spacer strips to keep an airspace between the tank and the insulation for the optimal install.  A similar application is insulating hvac ducts by wrapping the duct with 2” wide strips of double bubble and then wrapping the duct and spacers with the roll of insulation.

    T.A sent this image back of his insulated water tank.  Nice work, looks great! When asked what he did for spacers, here is his reply.

    “went to Walmart and got the white foam,3/8 in thick used for sending packages.  Comes in rolls or sheets and cut them in 2 in. strips and spaced them about 4 ins. apart and used the tape to hold it in place. Put them in up and down and made sure that they were resting on the slab.  Did it my self but took a long time. if I do it again will have someone to help me here in the AZ heat at 95. I am 73 years young, a Vet and in good shape for the shape I'm in.  LOL”

    Thanks again, T.A. We really appreciate the picture and sharing your project.

    A couple notes about why we recommended spacers.  1.  The use of spacers will increase the r-value by utilizing a trapped air space.  Again, in HVAC insulation, the r-value increases as spacers are used in the assembly.  2.  In addition, the airspace also allows the emissive properties of the material to work.  This means the inside reflective layer of the insulation, the side facing the spacers and water tank will only emit (the emissive value is opposite of the reflective value) 5% of the radiant heat that could pass through from the outside sun.

    This is a bit technical but basically you have an effective radiant barrier blocking 95% of radiant heat on both sides of the insulation in this instance.

  • Insulating Floor Joists – The Original Foil Insulation

    Take a look at this short post showing Infra insulation, the original reflective foil insulation used to insulate wood floor joists.  The three examples are:

    • In Floor Joist
    • In Floor Joist – Radiant heat in floor joist
    • In Floor Joist – Radiant heat imbedded in concrete

    The italics text below is an excerpt from the Simplified Physics of Vapor and Thermal Insulation, by Alexander Schwartz.

    The applications are the same today, see how to insulate floor joists with modern materials.

    Radiant Heat and Wood Floor Techniques

    Heat flow in Conduction and Radiation is from warm to cold in any direction.  The ground or the cellar area below a floor is usually colder than the inhabited rooms above, so there is considerable wasteful heat flow downward; first by direct conduction through the floor, then by radiation from the under-surface of the floor to the cold ground or cellar floor. 

    Multiple accordion aluminum has negligible conduction through its air spaces.  (In any air space, heat flow by conduction is only 5% to 7% at most.) There is no convection downward.  The preponderant heat flow downward is by radiation.  This will be reflected back 97% to augment the heat which the floor emits upward at a 90% rate.  Multiple accordion aluminum can reduce original and upkeep heating cost.

  • InfraStop® Used in 36,000 Sq.Ft Animal Nutrition Center in Missouri

    Here is a short post from our archives showing InfraStop® bubble foil insulation being used in a metal building application west of St. Louis, Missouri.  This large 36,000 square foot building is used for horses.  For this project we custom produced 72” x 75’ double bubble white rolls to accommodate our customer.  Click here for our standard size white double bubble insulation roll.

  • Exterior HVAC Insulation - Wrapping Ductwork with Foil Insulation

    This is great customer project to share.  Thanks H .J for sharing your photos.  H.J. wanted the HVAC lines running to his metal building located Southwest of St. Louis, Missouri insulated.

    InfraStop® double bubble foil insulation is a perfect product to use as it is inexpensive, easy to work with, performs well, and is impervious to moisture.

    H.J is very detailed as you can see in the pictures he sent over of this project.  Prior to ordering, we discussed his project and shared ideas on how to best insulate his exterior HVAC lines.  From here you can see how he insulated the lines from start to finish.  Look at the pieces he cut to work the 90 degree elbows.  What a great project!

    We explained the 3 different options available when working with double bubble foil insulation and the different R-value’s associated with each option.

    Option 1 (all seams taped, maintain airspace):  Loose wrap the insulation, R-4.1 Option 2 (all seams taped, maintain airspace): Wrap the insulation around spacers, R-6.0 Option 3 (all seams taped, maintain airspace): Wrap insulation around spacer 2 times, R-8.0

    Thanks again H.J for the photos and sharing your project.  This perfectly demonstrates how to insulate HVAC duct work located outside.

  • Insulating Metal Shipping Containers with Reflective Bubble Foil Insulation

    Check out this video showing a shipping container insulated with reflective bubble foil insulation. Awhile ago, we provided the insulation for a shipping container building overlooking the Freedom Tower and Statue of Liberty in New York City.

    We’ve been slow to get the footage of the project out, finally putting the video up on YouTube last month and now finally getting the blog post up.  See the video of insulating this shipping container here.

    This 3 story shipping container structure is actually an art exhibit that lies on the property of Pioneer Works, Center for Art and Innovation in Red Hook, Brooklyn.  The first floor bar is topped by a second floor recording studio, where the InfraStop® was used.  On top of the recording studio is a third story open air terrace.

    It took a few months for the crew of 4 including artist Gregory Kloehn to cut and weld the containers, deck, staircase, and window and door openings.  They also welded hundreds of threaded rods on the inside walls of the second floor to hold the wall framing members, insulation, and acoustical wall board.

    The studio took an additional several weeks to complete.  Here are some images of the inside at Pioneer Works, the grounds that the shipping containers are on, the shipping container second floor, and some great pics of the Statue of Liberty and Freedom Tower.  If you are interested in seeing some of the actual installation of the InfraStop® foil insulation click the link to the video above.

  • InfraStop® Bubble Insulation in Costa Rica: Under Metal Roof, Over Metal Purlins with Furring

    What a great project.  Look at InfraStop® insulation in action in this beautiful masonry home in Costa Rica.  We spoke with our customer M.F prior to him building his home.  He told us he wanted to use our insulation and explained the building and roof design.  We developed a good a rapport from there.

    Take a look at the project photos he forwarded to us.  Even though this is a beautiful masonry home, the roof structure and design is very similar to what we do with metal buildings here in the United States.  Notice the addition of wood furring over the purlins.  This creates a solid thermal break and eliminates the need for the recommended ¾” drape for this same installation without furring strips.

    A masonry home with a metal roof located in the tropics is a perfect InfraStop® project.  All of the attributes of the insulation are needed and InfraStop® fills them all.  A low profile, moisture proof insulation that reflects radiant heat, provides a vapor barrier, and provides some decent R-value.  Plus, when looking at the cost of all your building components, the cost of InfraStop® is minimal.

    Thank you very much for the images M.F.  Thank you for sharing.  We wish you well with your beautiful home.  Thank you for being our customer.

  • InfraStop® IR Reflective Pallet Cover

    How do Reflective Pallet Covers Work?

    Reflective pallet covers are usually made up of a few core components all working together to shield the items inside from irregular temperatures. In addition to specially-designed sheets that are usually made of plastic or foam, the covers also include metalized films that act as reflective material.

    To this end, these covers are designed with two goals in mind: minimizing the transfer of heat outside the pallet and preserving the temperature inside. In normal situations, radiant heat from sunlight exposure (for just one example) could be absorbed by a traditional pallet cover or other packaging materials, quickly causing the temperature of the associated items to rise in an unpredictable way. The right pallet cover, however, can stop this from happening no matter what is going on in the environment around it.

    Even in situations where a pallet of goods may be exposed to direct sunlight, reflective pallet covers block radiant heat entirely - allowing the condition of the goods inside the pallet to be unaffected regardless of the temperature in the surrounding environment.

    Extreme temperatures are one of the natural enemies of a wide range of different products. In the case of pharmaceutical goods, for example, allowing the temperature to get too high could alter the chemical composition of something like medicine, causing it to lose effectiveness or possibly to not work at all. In the case of fruits and vegetables, heat could artificially limit their lifespan - leading to a pallet of food that arrives at its destination in such poor condition that it needs to be disposed of right away.

    The Major Benefits of Reflective Pallet Covers

    By far, the number one benefit of using reflective pallet covers comes down to the superior temperature control capabilities they provide. Certain items that are shipped like food, flowers, pharmaceuticals and more could be harmed or totally damaged if they're allowed to heat to beyond a certain temperature. Unfortunately, due to the way that shipping facilities operate, you can't guarantee that a particular pallet will stay out of direct sunlight all day long.

    With a reflective pallet cover, however, these concerns can be eliminated because they're specifically designed to block radiant heat in the first place. This is especially true when you're talking about items that are shipped in steel containers, as the heat absorbed by the metal can cause the temperature to rise to extreme levels very quickly.

    By blocking radiant heat, reflective pallet covers can help preserve a safe temperature for the aforementioned types of perishable items and more, guaranteeing that they arrive at their destination as safely as possible every time.

  • InfraStop® IR Radiant Barrier - Metal Roof in Central Florida

    Thanks P.G for sharing your project with us. P.G’s shop is in Central Florida, West of Orlando and was not insulated. With a metal roof, this wood framed building was unbearable in the summer months. P.G. was looking for a tough radiant barrier so we sent down samples of our InfraStop IR radiant barrier, the heaviest and toughest product on the market today.

    Take a look at his project pictures he was kind enough to share with us. We checked back with P.G. after the install to see how our insulation was reflecting the Florida heat and here is what he had to say. You won’t believe the temperature difference is his shop.

    InsulationStop: Regarding the insulation, how is everything working out? Do you notice a difference?

    P.G: The installation process was smooth and easy. The product has made a huge difference for us. Our building has seen a 30 degree temperature drop. I am very pleased! Thank you, P.G

    Thanks again for being a customer of ours and sharing your project. We really appreciate your business and feedback.
