Conductive heat:
A type of heat that travels through solids, or transfers from one solid to another. The best materials for use in heat conduction are those with the most densely-packed molecules; because metals are molecularly dense, they are highly effective heat conductors.

 

Fiberglass fabric:
A chemical and corrosion-resistant insulating fabric, woven of spun-glass fibers. Fiberglass fabric is often used in heat-shielding and fireproofing applications.

 

Fireproof:
In order to be listed as fireproof, products and materials are typically coated or treated with a flame-retardant substance, and extensively lab-tested to prove their resistance to fire.

 

FRNC:
The abbreviation for Flame Retardant Non-Corrosive.

 

Heat deflection temperature:
The point at which a polymer, placed under thermal pressure, will begin to distort. Also known as heat distortion temperature (HDT) and deflection temperature under load (DTUL).

 

Heat deflection:
The distortion of a material under increased thermal pressure.

 

Mylar® :
An extremely strong, transparent polyester film made of biaxially-oriented polyethylene terephthalate (PET). Mylar can be made conductive with the addition of indium tin oxide, as well as reflective when an aluminum film is bonded to it. Mylar, developed by DuPont in the 1950s, is chemically stable, extremely heat-resistant, has barrier-like properties against gases and aromas, and is often used as electrical insulation.

 

NORYL SE100:
A registered name for an unfilled flame retardant material.

 

Radiant Barrier:
Amaterial whose reflective properties reduce the conduction of heat from radiant sources.

 

Radiant heat:
Heat given off in the form of electromagnetic waves.
