TABshield | Frequently Asked Questions

TABshield™ is a lightweight, easy-to-apply thermo-acoustical composite shielding material comprised of a thin aluminum foil facing laminated to an insulation core with a peel-and-stick adhesive tape backing. TABshield generally consists of a thin aluminum foil facing up to 10mil thick, fiberglass:polyester blend insulation core, and pressure-sensitive adhesive backing.

TABshield customization options include aluminum thickness, insulation blend, and adhesive backing type.

JBC recommends that TABshield™ is installed using its integrated peel-and-stick, pressure-sensitive adhesive backing. TABshield may also be installed using mechanical fasteners, but this installation method should be evaluated by the end user for proper fit and performance. TABshield can be cut to shape using scissors (thin gauge foil facing) and tin snips. Better yet, JBC can custom die-cut your TABshield to your exact size and shape specifications. 

If you want to shield something from excess heat or noise, TABshield makes an excellent choice. TABshield is a thermal/acoustic barrier material that acts as both a heat and sound barrier. TABshield offers targeted protection against heat and noise, and because it can be cut to shape, it can be placed precisely where it’s needed with minimal waste.

Before using the integrated pressure-sensitive adhesive to apply TABshield to any substrate, it's essential to recognize that the surface's condition will significantly impact the performance of the adhesive and, therefore, the performance of the TABshield itself. Adhesion factors to consider – the type of material to which you plan to adhere TABshield, the surface cleanliness and level of contamination, moisture, external temperature, and application pressure/time.

The maximum indirect/ambient air temperature exposure limit (continuous use) recommended for installations of most constructions of TABshield™ is 400°F (≈200°C). The end-user should evaluate TABshield installations with planned exposure to temperatures above 400°F.

Please consult your JBC Technologies technical service or sales representative for information regarding high-temperature insulation and adhesive backing options.

TABshield™ does not have a standard constriction. TABshield represents a family of products represented by three different product series:

  • TABCORE: Insulation only (with or without pressure-sensitive adhesive)
  • TAB100 Series: Aluminum Foil + Insulation available with or without pressure-sensitive adhesive backing
  • TAB200 Series: Aluminum Foil + Insulation + Pressure-Sensitive Adhesive backing

Unless otherwise requested, TABshield series products have a 50:50 fiberglass:polyester blend insulation and adhesive-backed options feature a peel-and-stick high-temperature acrylic PSA. Other customization options are available upon request.

Depending upon your volume requirement, the core series of TABshield products can be customized in several ways to suit your application. You can tailor TABshield to your performance requirements by choosing the

  • Aluminum foil thickness
  • Core insulation
  • Pressure-sensitive adhesive backing
  • Foil surface embossing (texturizing) and/or microperforating (tiny holes)

TABshield meets the requirements of Ford OEM specification WSS-M99P32-E6.

Some typical automotive applications for TABshield™ thermal acoustic barrier material include:

  • Fuel tank
  • Engine compartments
  • Tunnel and dash insulator
  • Exhaust shields
  • Under-hood insulators
  • Chassis/Frame insulation
  • Wheel wells
  • Engine shield
  • Trunk insulator
  • Floor pan
  • Intake tubes
  • Rear kick-up

TABshield isn't offered in a standard or base construction, but as an example, the average thickness of a TABshield construction consisting of a 3-mil aluminum foil, fiberglass:polyester blend insulation core, and high-performance pressure-sensitive adhesive backing is approximately 0.16 in (4mm).

You can use TABshield™ thermal and acoustic barrier material outside automotive applications in marine engine shielding, industrial machine noise and thermal reduction, HVAC, and even appliances. We recommend you test TABshield in all applications to ensure applicability and performance.

Cold temperatures can negatively affect the adhesive tapes used on TABshield™ thermal acoustic barrier material. For best results, we recommend an installation temperature of at least 60°F (about 16°C).

The standard JBC foil embossing pattern is called "pebble" and features a repeating pattern of raised bumps approximately 0.063 in (1.6 mm) in height with a density of 31 bumps/in².

The standard JBC foil microperforating pattern features a repeat of tiny holes (microperforations) approximately 0.016 in in diameter (0.4 mm) spaced 0.08-in (2 mm) apart with a density of 325 holes/in².

Embossing the foil facing of TABshield™ imparts stiffness to the thin metal foil and supports vehicle lightweighting efforts while helping to control design costs.

Compared to flat, feature-less substrates, embossed sheets are easier to form into larger, 3D-formed pieces such as engine dash insulators, hood insulators, and tunnel shields for underbody systems. Embossing also supports smoother transitions across rough corners and enhances noise reduction by disrupting sound waves.

Micro-perforating creates tiny holes in the aluminum foil facing of TABshield™. These holes or micro-perforations improve acoustical performance by absorbing noise across a specific frequency range. Micro-perforating, particularly for automotive heat shielding applications, also complements manufacturing processes like embossing and lamination.

JBC Technologies can make TABshield™ with aluminum foil thicknesses up to 10mil (0.25mm). Foil types other than aluminum and thicknesses above 10-mil may be available upon request.

Yes. TABshield™ can be applied to low surface energy (LSE) materials using the optional LSE adhesive. LSE adhesive tape backing is available for an upcharge upon request.

Some common examples of low surface energy (LSE) materials include powder-coated metals, high-density polyethylene (HDPE), Teflon, polypropylene, and Nylon.

New and unused TABshield™ sheets and rolls should be stored in a climate-controlled environment free from wide swings in temperature and humidity. The ideal storage temperature for TABshield is between 50 – 70°F (10 – 21°C) and away from moisture and direct sunlight.
