3. PRODUCT
DESCRIPTION:
BASIC
USE:
Nelson PLW is a compressible firestop pillow. It is well-suited
for installations where frequent changes may be required. When exposed to
fire, the pillows expand to lock the seal in place. Although excellent for
temporary seals, Nelson PLW is classified as a permanent firestop system
for several applications to include cable trays (steel and
aluminum).
COMPOSITION AND MATERIALS:
Nelson PLW, consists of a
mineral fiber treated with a highly intumescent material enclosed in a
strong polyethylene bag. The pillows release no disagreeable toxic or
hazardous fumes during installation, and no special precautions are
necessary for either installers or occupants of enclosed
spaces.
APPLICABLE STANDARDS:
UL 1479, Fire Tests of
Through-Penetration Firestops. ASTM E-814, Fire Tests of
Through-Penetration Fire Stops. ASTM E-119, Fire Tests of Building
construction and Materials.
APPLICABLE CODES:
Nelson PLW meets the
requirements of all three model building codes (National Building Code,
Uniform Building Code, Standard Building Code), as well as the National
Electrical Code, the Life Safety Code, and most state and city codes. For
specific approval information contact Nelson.
LIMITATIONS:
The outer
shell of Nelson PLW should not be exposed to chemicals harmful to
polyethylene. Service temperature shall not exceed 275°F.
