SUPERLITE
HEAT PROTECTION, CLEAR VISION AND COMFORT WITH SUPERLITE™
SuperLite I-XL tm is a US
manufactured 60 minute fire and safety rated glazing material. It is
designed for use in fire doors, sidelites, and windows, where fire
protection is required from only one side.
SuperLite I-XL has a
proprietary coating which provides radiant heat and fire protection from one
direction when the coated surface is oriented to the fire.
APPLICATIONS
This unique product offers a
solution to special fire rated conditions: property line demands, retrofit
and replacement work, historical buildings, schools & universities,
manufacturing facilities and commercial buildings. The SuperLite I-XL
product also lends itself to a new market, residential construction and in
wildland areas.
SuperLite I-XL carries a 60
minute listing from Warnock Hersey for use in doors, sidelites, and borrowed
Iites with special limitations. SuperLite I-XL does not meet the hose stream
requirements specified by model building codes, and it is a directional
product providing protection from one side only.
Heat from fire is
transferred in the form of electromagnetic waves. Invisible, extremely
intense, and travelling with the velocity of light, they are able to pass
through air without being significantly impaired. Normal monolithic glazing
materials will permit a maximum of 50% of this radiant energy to pass.

BENEFITS
COMPARISON OF FIRE RATED GLAZING PRODUCTS
Recent and conclusive
testing by the US Coast Guard and Warnock Hersey Laboratories shows the
differences in radiant heat flux amongst fire rated glazing products.
Radiant heat testing was conducted on a variety of fire rated glazing
products. The results show that considerable heat is transferred through
both wired glass and ceramic glazing products.
Another critical point is
that there is almost a 100% increase in radiant heat flux through the
glazing in the last 15 minutes of a 60 minute fire test. Using a 60 minute
fire rated glazing product which doesn’t offer radiant heat protection
significantly increases the potential for loss of human life and destruction
of property.
SUPERLITE II-XL TAKES THE HEAT
SuperLite I-XL offers
considerable protection from the hazards of radiant heat. Supertite I-XL
transmits only 1 kilowatt of radiant heat flux at 60 minutes into a fire
test when measured 2 meters from the surface of the glazing. SuperLite I-XL
is an excellent option in fire rated applications that require clear vision
as well as a higher degree of fire resistant protection.
APPLICABLE FIRE AND SAFETY TEST STANDARDS
SuperLite I-XL was exposed to
time-temperature curve and fire exposure conditions specified in NFPA 252,
Standard Methods of Fire Tests of Door Assemblies.
Surface temperature of the glazing and
radiant heat flux were taken at 15 minute intervals.
The cotton pad test in which a cotton pad is
placed on the surface of the glazing, was conducted at 15, 30 and 45
minutes. SuperLite I-XL is safety rated conforming to both CPSC 16 CFR part
1201, category II 400ft lbs federal standards and ANSI 797.1 required by
Model Building Codes safety standards for use in glazed doors, sidelites,
and other hazardous locations.
