  • Top 3 Benefits of Insulating Your Crawlspace

    InfraStop® Double Bubble Crawlspace Insulation

    If you are looking for a way to improve the comfort of your home and protect it from the elements, insulating your crawlspace is the right thing to do. Fortunately, there are multiple benefits to improving these dynamic areas of your house. Look to the following advantages when deciding on whether to upgrade your crawlspaces.

    Critter Protection

    One of the best parts about insulation is that it can keep critters from entering your home, which is positive for you and your loved ones. Whether it's roaches, spiders or mice, it is important to keep pests from turning your house into a breeding ground. No one likes to unwanted critters in their kitchen pantry or on their bathroom floor. By properly insulating your crawlspace, you're more likely to keep unwanted bugs and pests out of your living spaces.

    Energy Efficiency

    Insulation also helps retain heat in your floors, which is important during the wintertime and can cut down on your utility bills. Whether you have vented or unvented crawlspaces, adding insulation greatly improves the way your home uses energy. Double-bubble foil insulation is an ideal crawlspace insulation because of its high thermal performance in crawlpsaces and that this performance is not affected by moisture which is vital in any crawlspace application.

    Structural Protection

    Adding a protective layer of insulation also shields vital materials and structures within your home. It can keep mold from forming by keeping moisture out. Mold can pose serious health hazards to you and your family members, so keeping it out of your crawlspaces is a priority. Structural damage to your home can cost a lot of money and if it is bad enough you will need to hire a qualified contractor to repair and damages. An ounce of prevention is worth a pound of cure in this case. If you want to increase the value of your home and protect it from the elements, then insulating your crawlspaces is the way to go. The benefits of this upgrade will make your home more comfortable, safe, and efficient.

  • Crawlspace Insulation: An Ideal Bubble Foil Application

    Crawlspace Insulation - Staple TabIf we had to name one of the best performing applications for our Tempshield bubble foil, it would have to be for crawlspace insulation. Solid r-values are achieved in this application as well as foil insulation's proven ability in moisture prone areas. There are two standard insulation methods.

    You can run insulation perpendicular to the bottom of the floor joists or use Tempshield staple tab foil insulation to insulate between the floor joists. Either way you've created a radiant barrier to block the transfer of radiant heat.

    This installation is also perfect for beneath floors with radiant heat. When you insulate under the floor joist, the lost radiant heat from the floor is reflected back decreasing your energy demand. This is especially important in crawlspaces that are not air sealed during your heating season. You can easily have a 50 degree temperature swing between the inside temperature of your home and that of your crawlspace. Putting a radiant barrier in place can be a quick, inexpensive project that can insulate a key area of your home with immediate savings in your heating bills.

  • The History of Radiant Barriers for Wall Cavities

    When it comes to insulation, there are products and the applications they are installed in. The specific applications determines the product used and vice versa. Staple tab is a unique product design that allows bubble foil insulation to be installed correctly and efficiently in a wall cavity. Here's some great information on the history of radiant barrier use inside walls, ceilings, and crawlspaces.

    The modern day staple tab insulation is standard double bubble foil insulation manufactured with a tab or extra material in order for the insulation to fit between studs or joists. This allows you to use radiant barriers in your walls and ceilings. You use the tabs to staple the insulation inside the cavity at whatever depth you require. This guarantees at least one airspace is created, giving you an ideal radiant barrier installation.

    This concept is certainly not new. Years ago, testing labs and government agencies such as the National Institute of Standards & Technology discovered how effectively radiant barriers worked using dead airspaces in building construction. This technology was even more effective if there were multiple reflective layers. This led to the development of accordion aluminum foil insulation. Over 300,000,000 square feet of accordion foil insulation was manufactured and installed in the 1940's and 50's here in the United States. Two notable examples from this time are the Frank Sinatra residence in Palm Springs California (Harry Williams & Sons, architect). Another is the student housing at the Massachusetts Institute of Technology, MIT.

    Today, the same technology is used in the same applications only the product has changed. Now reflective cellular insulation is the low cost, affordable way to install radiant barrier insulation in a wall or ceiling cavity. This is why staple tab is used with great results in walls and ceilings. The product comes in 16", 18" 24", and 48" widths allowing you to insulate any cavity. Staple tab insulation is the leading product used for radiant heat applications and crawlspaces as well.

    Take a look at some of the accordion insulation images of yesterday compared to the staple tab insulation today. You will see the applications have not changed at all, only the product has.

  • Insulate Walls, Ceilings, Crawlspaces with Staple Tab Bubble Foil

    What is staple tab? Staple tab refers to an option in the product design that allows the insulation to recess into the stud or joist bay. The "staple tab" is a run of extra material or a tab that you can staple to. The insulation fits recessed slightly in the wall cavity and stapled to the inside of the stud or joist. Creating this airspace is critical for maximum effectiveness.

    As radiant barrier technology is all about reflectivity and airspaces it is important to note that there are only two ways to insulate finished walls and ceilings with reflective foil and keep the recommended air spacing. The first is again using staple tab or "ST" insulation, where you recess the insulation in the stud of joist bay then apply the finished interior wall material. This ensures at least one airspace. You may have an additional airspace on the exterior side depending on your wall construction. This further improves the effectiveness of the insulation.

    The second is with furring strips. Apply squared edge reflective insulation perpendicular to the studs or joists. After insulation is installed, run furring strips over the joists or studs before applying finishing material. This ensures keeping the correct airspace no matter what happens on the opposite side of the insulation. For hollow walls and ceilings the furring strips are not necessary as the airspace is the hollow section before the exterior building material. However utilizing furring strips in this example would be ideal because two airspaces would exist, again further improving the insulation's effectiveness.

    Staple tab foil insulation comes in 16", 18", and 24" widths to accommodate various stud and joist bay widths. This allows you to insulate any wall, ceiling, or crawlspace. Here are some links to specific applications with installation instructions.

    Insulating walls and ceilings is done in new construction or remodeling projects. Crawlspaces however can be insulated anytime. If you know your crawlspace is causing unwanted heat transfer, insulating with reflective foil is a low cost insulation project with maximum, lifetime returns. Take a look at these two crawlspace applications and see the performance.

  • How to Reduce Condensation with Reflective Aluminum Foil Insulation

    How to Reduce Condensation with Reflective Aluminum Foil InsulationAs well as reflecting and blocking radiant heat, radiant barriers and reflective foil insulation are also great at reducing condensation. Today's "Staple Tab" Bubble Foil Insulation is what is used in between in walls, ceilings, and crawlspaces. Years ago reflective insulation was also used but in a different design. The product was multiple accordion aluminum insulation which basically comprised of layers of reflective foil with trapped airspaces. Here is an informative description on how accordion insulation was used to help reduce and control moisture.

    "Prevent Damage to Wood, Plaster, Paint, etc.

    As air becomes colder, it can hold less vapor in suspension. The degree of saturation increases until a dew-point is reached and condensation occurs.

    Heat flows from warm to cold by conduction. A material which is in contact with air colder than itself on one side and air warmer than itself on the other side, will continuously extract heat from the warmer air by conduction and lose it to the colder air. As the contacting warmer air becomes cooler by this action, the amount of vapor it can hold in suspension without condensing becomes smaller.

    The denser and bulkier the material, the more heat it can extract before attaining room temperature, if it ever does. The scientific construction of multiple layers of aluminum, fiber and reflective air spaces minimizes condensation-formation on or within this type of insulation, when installed in building spaces.


    Since the sheet of aluminum adjacent to the warm, inner air of a building weighs only about 1/4 oz. per sq. ft., it does not need to extract much heat from that air to attain and remain at room temperature. Since the emissivity of the aluminum surface is only 3%, little heat is lost by radiation on the cold side. This further enables the metal to remain at about room temperature and not extract much heat from that warmer air.

    Since the other sheets of aluminum and fiber retard heat flow by inner as well as outer convection, and since conduction is slight through the preponderant low density air spaces, each sheet's other surface faces a space which is only a little colder than the aluminum itself. But because warmth flows to cold in conduction, the aluminum will give off a slight amount of heat to the colder space, thereby slightly increasing the vapor retaining capacity of that space. The successive reflective spaces and sheets of aluminum and fiber behave similarly. Since each aluminum surface is slightly warmer than the air it faces on its cold side, there is no extraction of heat. The reverse is true.


    When multiple accordion aluminum is used, fortuitous vapor and water ( like rain) which intrude into building spaces will, as vapor pressure develops therein, gradually flow out as vapor through exterior walls and roofs because vapor flows from areas of greater to areas of less vapor density. Since the vapor cannot back up through the continuous, almost impervious metal, it will flow out because exterior walls and roofs have substantial vapor permeability compared with aluminum, far greater than the required 5 to 1 ratio.

    Of great importance is the use of a continuous metallic vapor barrier, of almost zero water vapor permeability, without "breaks" every few feet, to retard the outward flow of vapor which originates inside the house. Infiltration under the flat stapled flanges of multiple aluminum is slight.

    To obtain MAXIMUM, uniform-depth protection against heat loss and condensation formation, it is necessary to use the new edge-to-edge multiple aluminum*, each sheet of which stretches from joist to joist.
