Aluminum Laminated
Fiberglass Cloth and Tapes

Natura-Biotic provides an aluminum laminated fiberglass cloth and tape product line. This
excellent material is engineered by laminating an aluminum heat shield to a layer of strong
fiberglass insulation. This system provides superior protection from radiant heat by reflecting it
away from sensitive electronics, wiring and hoses.

Aluminum laminated fiberglass fabrics create a buffer between your wires, hoses and cables
and the high temperature environments they are required to perform in.

Natura-Biotic's aluminum laminated fiberglass fabrics are available in tube, wrap around and
full adhesive backed products to provide the right solution for virtually any installation
requirements

Heat transfer

Materials transfer heat in three ways:

* Conduction.
* Convection (essentially = conduction + fluid flow).
* Radiation.

Conduction, the most common means of heat transfer in solids, is the transfer of heat through
atoms and molecules that are in direct contact with one another, when there is a temperature
gradient between them. Materials with high thermal conductivity, such as metals, transfer nearly
all of the heat via electrons, whereas materials with low thermal conductivity – insulators –
transfer nearly all of the heat via phonons.

Convection, the most common means of heat transfer in liquids and gases, is the transfer of
heat via a combination of conduction and fluid flow. For example, when you heat water on a
stove, the entire pot of water warms up uniformly. The reason is that hot water at the bottom of
the pan doesn’t just heat surrounding water via conduction, but also becomes less dense,
rises, and heats the water in the middle and at the top of the pan. Once the water cools, it
becomes more dense, sinks, picks up heat from the bottom, and continues the process.

Radiative heat transfer is the transfer of heat via photons (electromagnetic radiation). Radiation
is the only form of heat transfer that can occur in the absence of any form of medium – through a
vacuum. Movements of atoms and molecules cause the emission of photons into the
surroundings constantly, carrying away some of the heat. Atoms and molecules are also
constantly absorbing photons from other atoms and molecules. Since hotter materials emit
more radiation than cooler materials, a net transfer of heat occurs from the hotter materials to
the cooler materials. For room temperature objects, the majority of photons emitted are in the
infrared spectrum. Hotter objects transfer heat through emission of photons in the visible
spectrum or beyond

Insulation is any material used to reduce or “slow down” or “resist” the flow of energy. There are several different types of
insulators:

* Thermal insulators reduce the flow of heat.
* Electrical insulators reduce the flow of electricity.
* Acoustical insulators reduce the flow of sound.

Insulators reduce the flow of heat by reducing one or more of these heat transfer mechanisms. For example, a layer of thick
foam can reduce convection and conduction. A reflective metallic film or coat of white paint can reduce thermal radiation. Some
materials are good insulators using one heat-transfer mechanism, but poor insulators using another. For example, metals
tend to be excellent radiative insulators, but poor thermal (conductive) insulators.

Natura-Biotic's aluminum laminated fiberglass fabrics provide insulation dealing with all three types of heat: conductive
heat, convective heat and radiative heat. Those materials are excellent insulation for various industrial applications.
