  • Foil Insulation Used in Desert Climate - Outdoor Sun Shade

    Recently we were contacted by a customer looking to use our foil insulation for creating outdoor sun shades in a desert application. Take a look at our email correspondence and his project images below. Thanks S.J for sharing your project and using one of our radiant barriers. Thanks also for the descriptive feedback.  The results looks great!

    Hi, I have an unusual application, and I wonder if this product would work. I live in the desert in an RV, and the direct sun here is unbearable. It heats the sides of the RV until the heat comes through.

    I made 9' tall "curtains" out of 90% sunblock shade cloth (like they use in greenhouses) that cover the entire sides of the RV from the roof line, down to about 18" from the ground, and they are suspended about 8" away from the sides of the RV to allow for airflow.

    Unfortunately, the sun is SO hot, that the UV & heat is mostly going right through the cloth, so I had the idea to use a product like this to line the back side of the shade cloth curtains. They are only attached to the rv at the top, and hang freely, so on a windy day they do blow & move with the breeze.

    Would this product be durable and effective for this application, or would it come apart in the breeze, or from the direct sun and rain storms?

    Thank you very much for your help, have a great day.  S.J

    After following up with S.J we were pleased that to hear his response.  See below:

    Hi Nick, Yes, I have used it and I'm impressed so far.  It's strong, and hopefully it will not tarnish or dull from the UV & weather exposure.

    I used it to line between the beams under my solar panels which are mounted flat on the roof, and it definitely lowered the temperature of the roof.  I also made curtains to use under the shadecloth curtains I mentioned to you earlier.  In addition to the aluminum tape you sent (which tears very easily, and would not have been nearly enough on it's own) I used nylon filament tape to go around all edges on the back side & every few inches across the seams under the foil tape to give strength & provide anchor points along the bottom.  I also used heavy shipping tape on the back side to reinforce the seams.   I have 1" nylon webbing that I plan to use to sew all seams & edges with in the future, once I make sure the curtains will last.

    I did take a pic of the roof under the panels, it's attached below.  I'll take pics of the curtains too.  

    Thanks and have a great day.  S.J

  • InfraStop® Reflective Insulation for Outdoor Use?

    Although we do not warrant InfraStop® for outdoor use, this doesn’t stop our customer from using it effectively in their projects.

    Folks ask us all the time how the product will perform outside. Here’s a quick post showing what’s left of one of our customer’s wood racks. Thanks S.N for the photos. S.N used InfraStop® to cover 2 cords of wood. The 24” material was the perfect width to cover just the top leaving the sides exposed. S.N grommeted holes in the InfraStop® and tied off cut sections of 2x4”s for weights.

    The InfraStop has been outside continuously since 2013 and as you can see is holding up fine. Note how the grommets are rusting out already.

    Thanks S.N for the pictures. We appreciate them. In the next few months we put up some more posts showing InfraStop® insulation used outside. Here's a link to the roll size S.N used for a firewood tarp.

  • 5th Wheel Camper Insulation - InfraStop® Performs Again

    We are always happy to show off all the ways our InfraStop® insulation can be used. Although we are primarily geared to provide InfraStop® to the construction industry, we know there are many other applications are products are used in and this project is no different.

    We would like to send a special thanks to our customer S.F in the rural outskirts of Houston, Texas for sharing his project with us. S.F called in and wanted our InfraStop® for use as 5th wheel trailer insulation.

    Although we insulate campers and trailers all the time, S.F’s project is unique for two reasons. The first is, as you can see from the pictures, he chose to insulate his trailer from the outside. From understanding the blistering heat in Texas and also understanding that this would be the most effective way to keep this 5th wheel cool this is what he decided to do, well before he called us.

    The second reason that S.F’s project is unique is he wanted an easier install so he ordered a custom roll of 10 foot wide InfraStop® double bubble insulation. Although typically used for large metal building or pole barns, allowing us to tape the seams and create the ten foot roll in the factory was much easier than him assembling on the ground or on top of his trailer.

    We would like to save thank you to S.F for sharing his project. We have reached out to him to see how the insulation is performing and will update this blog post with his comments.

  • Retrofit Insulation for Air Dome – Insulating After It’s Built

    What a great project and we sure learned some new tricks.  InsulationStop received the call from the owner of an air dome in Central Pennsylvania.

    Our client had recently added an air conditioning unit to his existing air dome and wanted to insulate the dome to retain as much cool air as possible.  We provided custom length InfraStop® double bubble foil to meet their requirements.

    The InfraStop® was installed by an ingenious method of cutting pilot holes at the top of the dome sections.  A wrench tied to a long cable, acting as a snake, was tossed to the bottom.  Working from automatic lifts, workers pulled the insulation to the top and tied each left section to its corresponding right section.

    Check out some of these images to get an idea of the scope of the project and take a look at the video below showing the actual installation of one of the sections.

    We would like to thank our customer for allowing us access to their jobsite. This was definitely a great project to participate in.

  • InfraStop® Concrete Pad used in Wooden Pool Restoration Project

    Many thanks to our customer, B.E in Chicago, Illinois for sharing his unique project with us.  B.E built a wooden pool back in the 1970’s for his house.  After years of use, and then some years of no use he decided to restore the pool by pouring a new slab in the bottom and replacing the liner.

    B.E wanted to keep as much heat in the pool as possible so he decided to insulate under the slab.  Check out this project showing our InfraStop® Concrete Pad used as a thermal break to slow the transfer of heat out of this homemade, wooden pool.

    Typically customers will want to use our standard product for insulation in above ground pools.  B.E’s project is unique because he is using our concrete pad insulation in a pool restoration project.

    Thanks B.E for sharing your project.  We really appreciate it.  This is another great example demonstrating the flexibility of reflective insulation and the many unique areas where it can be used effectively.

  • InfraStop® Foil Insulation used in Thermal Remediation Building Construction

    Typically, companies specializing in thermal remediation will come to a home or building to remediate the premises. But what happens if you want to bring furniture into your home or facility. One company, understanding this limitation, converted an existing garage and used our foil insulation to construct a thermal remediation site that you can bring furniture, clothes, and bedding to prior to entering your property.

    We think their business is a great idea. You should be able to purchase items and not have to worry about bugs and other unforeseen pests. We are big fans of craigslist, craft fairs, flea markets, or anywhere individual transactions can happen. Also, the quality of older or previously owned goods is often superior to many products available today.  Items purchased in these marketplaces may be a perfect candidate for thermal remediation.

    When they decided to use our InfraStop® insulation to construct their local remediation site we asked if they would share some project pictures with us and they did. After researching their business to create this post we learned that thermal remediation and bug and other pests issues are a big deal. Check out some of these videos about bedbugs here if you don’t think so.

    We would like to thank our customer for offering a service that can be really helpful to a wide range of people and for using our products. Thank you, Heartfelt Homecare in Ohio for sharing your images and your story with us.

    The image gallery bellows shows our InfraStop® foil insulation being used to create their hot room. The job of InfraStop® is to reflect radiant heat and it is the perfect material to use when constructing a thermal remediation room. We hope you enjoy the images and visit Heartfelt Homecare’s website here at www.heartfelthomecarellc.com/ to learn more about their thermal remediation services.

  • Vintage Aluminum Insulation for Masonry Wall Applications

    Figuring out how to best insulate your masonry wall can be difficult. This is due partly because masonry walls appear in a variety of instances within structures. For example, in the Southeastern U.S for example an entire home may be built with block. In the Northeastern U.S. basements are typically the only masonry wall.

    Infra Insulation: Type 4 Jr. Infra Insulation: Type 4 Jr.

    Choosing which product and what wall thickness takes some thought and knowledge of your specific project. You want the wall to breathe but not allow moisture transfer. You also want the products used to be impervious to moisture. Even a little moisture in a wall cavity can severely limit many products insulation qualities.

    This picture shows how Infra insulation was installed in masonry and block wall applications.  Infra is accordion style aluminum insulation used in the 1940’s to 1960’s. This particular Infra product, the Type 4 Jr. was ½” thick.

    Type 4 Jr. was installed by attaching the insulation to the face of the studs with an occasional staple with the flat surface facing the room. As you moved to the next stud bay you would lap the insulation over the adjacent piece. Then nail lath strip or small piece of furring spaced evenly over both flanges down the center of the stud. This prevented contact with the lath/plaster that was used at the time and created the necessary air space.

    Here are the specs for Infra Type 4 Jr:

    Aluminum sheets ½” apart, .0007” thick, permanently separated by an accordion partition of flame, mold, and vermin resisting fiber. 4 reflective spaces; 4 reflective surfaces; zero permeability; non-condensation-forming; non-moisture-retaining. Will force out fortuitous vapor. For 16” centers.

    As multiple accordion aluminum, Type 4 Jr. stops radiant heat flow and body discomfort, summer and winter because it is only 3% absorptive, 3% emissive. The human body, and building walls, absorb and radiate, from warm to cold, at a rate of more than 90%. Convection is blocked, conduction is insignificant.

    Infra Insulation products were the pioneers for today’s reflective insulation industry. We insulate today with our Infrastop® insulation the same way it was done 75 years ago. Look here to see how InfraStop® is an excellent block and masonry wall insulation.

  • Understanding Solar Radiation in Buildings - Simplified Physics

    In summer, considerable radiation from the sun is absorbed by buildings, because the outer surfaces of most roofs and walls have high absorptivity.

    Much of this radiant energy absorbed from the outside turns into heat, which flows by conduction through the solid material to the cooler inside surfaces of the roof and wall. The radiation inward from those inside surfaces, across buildings spaces, of invisible infra-red heat rays, is considerable, because these surfaces usually have over 90% emissivity.

    Black, non-metallic surfaces such as asphalt, slate, paint, paper, etc. are poor insulators against heat rays in either case, outside or inside; with 85% to 98% absorptivity for solar radiation, and 90% to 98% in enclosed spaces.

    Aluminum paint or gilt paint as it is formerly known, while it lasts, has a radiant heat absorption and emissivity of 40% to 65% in enclosed spaces. It performs better outdoors, with only 30% to 50% absorption for direct solar radiation. (1955 ASHAE Guide, page 95)

    White paint, whitewash, white tile, white brick and plaster perform well outdoors, with absorptivity for solar radiation of only 30% to 50%. But they perform very poorly in enclosed spaces, no better than black paint, with an absorptivity and emissivity of 85% to 95%. (1955 ASHAE Guide, page 95)

    Brick of any color, and concrete, in enclosed spaces, have an absorptivity and emissivity of 85% to 95%. But for solar radiation outdoors, red brick and concrete have an absorptivity of 65% to 80%; while yellow and buff brick have 50% to 70% absorptivity.

    One reason for this difference between indoor and outdoor absorptivity and emissivity is that in addition to the infra-red heat ray rays of frequencies or wave lengths corresponding to those found at ordinary building air space temperatures; the sun emits heat rays of frequencies or wave lengths corresponding to a broad range of other temperatures. The sun also emits other rays, visible and invisible. All of these rays, with heat rays predominating, engender a certain amount of heat when they strike a surface and are absorbed, for example by the outer surface of the roof or wall of a building.

    There is also sky or diffuse radiation from the surrounding atmosphere, also from buildings, trees, etc.

    Enclosed building spaces are usually without light. Everything is dark and colorless. Radiation between surfaces in such space is limited largely to invisible, infra-red heat rays.

  • Protecting your Flock: What Chickens Need in Winter

    Are you really ready for cold weather? If you own chickens, you may not be -- keeping them warm and dry is essential if you want to avoid frostbite, respiratory and related health issues this year; insulating your coop can protect your birds and keep them in an optimal setting year round. The insulation and protection you need to provide for your chickens in winter depends on several factors. You’ll need to consider the average low temperature where you live, the way you insulate your coop and even the varieties of chickens you have.

    How cold does it get where you live?

    If you live in a state that occasionally drops below freezing, but otherwise has mild winters, simple insulation and blocking drafts will help keep your birds warm all year round. For those with regular freezing temperatures at night, snow and sleet, more aggressive insulating measures may be needed.

     How hardy are your birds?

    Some breeds are more winter hardy than others and will be comfortable in temperatures that are too cold for you. If you have purchased your chickens from a hatchery or local breeder, you should have an idea of how hardy they are; big robust and healthy birds like Orpingtons, Jersey Giants and Rhode Island Reds are known for being cold hardy, as are many Sex Link Hybrids. Despite their hardiness, insulating your coop can prevent comb and foot issues, even in these larger birds. If you have bantams, Silkies or very young chicks, you’ll need to take more measures to insulate your coop.

    What is your coop setup like right now?

    Would you want to spend the night? No matter how your coop looks, unless two or more walls are solid, your chickens are likely too exposed to cold weather. Covering two or more walls with a durable, chicken safe insulation can help keep your pets warm. If you do have walls, covering the exposed or wind side of the run can help provide a dry spot for winter scratching, even if it snows or rains outside.

    Insulating your Coop

    Your chickens generate enough body heat to stay warm, provided you insulate your coop. By wrapping two or more sides of your existing coop with a good quality insulator that is chicken safe, you can keep them warm without resorting to a dangerous outdoor heater. Insulated coops stay warm enough to prevent waterers from freezing, so you can be sure that your birds stay healthy and hydrated

    Insulation works so well, you actually have to remember to leave a gap at the top of the coop for heat to escape; too much warmth can cause humidity levels to rise and can be uncomfortable for your birds. Insulate all but the top few inches of your coop to allow warm air to escape and to keep your birds toasty warm and dry.

    • While any material can be used to block winds and drafts, some are far superior to others. Simply covering the coop with a trash bag or floor cloth isn’t enough. These materials won’t hold up for long and could even be dangerous if your chickens decide those dangling strands of plastic are food.
    • A reflective bubble insulation for the chicken coop allows you to safely insulate your birds as needed, without the risk or headache of using a flimsy plastic. The bubbles trap air, helping you maintain a warm coop just with chicken body heat, while the reflective layer allows light inside. If you have year round layers, even an additional hour or two of light per day can make the difference between daily eggs and occasional eggs in your nesting boxes.
    • Covering one side or the top of a scratching area can help insulate it while repelling airborne predators. Hawks get particularly aggressive when food supply dwindles in winter and a reflective surface can help protect your birds from predation.
    • Choose a chicken friendly insulator like reflective bubble wrap and set aside an hour or two to insulate your coop before the really cold weather arrives. Once this task is done, you can be sure your birds are safe, warm and dry no matter what the weather is like outside.

    We have provided insulation for a lot of chicken coops. We’ve got you covered – literally! Find your wrap among these sizes to keep your birds safe this winter.
