• Steel & Metal Buildings: Airpace Requirements for Reflective Insulation

    Reflective insulation requires an existing airspace on one side of the insulation in order to work properly as a radiant barrier. This airspace may be small but it is essential. Foil insulation used without an airspace, as in under concrete insulation for example cease being a radiant barrier.  You still get some insulation value but it's in the form of a thermal break, not a radiant barrier.

    Tempshield double bubble reflective both or reflective one side products have been tested in various metal building applications and achieved various r-values depending on the installation.

    Please take a look at our metal building insulation airspace page where you can find the required airspace, application, and r-value for all of your barn insulation needs.

  • 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.
