TEMP. NOTES
CALCIUM SILICATE Pipe Insulation BlockSegments to 648.9oC (1200oF)to
648.9oC (1200oF)to 648.9oC (1200oF) ** Strong for its weight, good cutting
characteristics, some are water absorbent,noncombustible. Some manufacturers
limit to 648.9oC (1200oF). See manufacturers' data for shrinkage
factors.
GLASS CELLULAR Pipe Insulation BlockSegments
to 482.2oC (900oF) ** Good strength, water & vapor resistant,
noncombustible, poor abrasion resistance. For application, see manufacturer
specifications.
GLASS FIBER Pipe Insulation BoardBlanket to 537.8oC (1000oF)
to 537.8oC (1000oF)to 537.8oC (1000oF) ** Good workability, water absorbent,
noncombustible. Check manufacturers' data for specific properties.
MINERAL FIBER Pipe InsulationBlock BoardBlanket (Felt) to 648.9oC
(1200oF) to 1037.8oC (1900oF)to 648.9oC (1200oF) to 732.2oC (1350oF)
** Good workability, noncombustible. Check manufacturers' data for specific
properties.
PERLITE(Expanded) Pipe Covering Insulation Block to 815.6oC (1500oF)
** Good workability,noncombustible, friable. Check manufacturers' data
for specific properties.
CERAMIC FIBER (Refractory Fiber) Blanket Board to
1482.2oC (2700oF) to 1648.9oC (3000oF) .115 @ 537.8oC (.80 @ 1000oF).123
@ 537.8oC (.85 @ 1000oF) Temperature range varies with manufacturer,
style and type.
CEMENT Hydraulic Setting Cement High Temperature Mineral WoolPointing
and Finishing Cement (Mineral Fiber or Vermiculite) to 648.9oC
(1200oF)to 1037.8oC (1900oF) to 760.0oC (1400oF) .252 @ 315.6oC (1.75 @
600oF).099 @ 315.6oC (.69 @ 600oF)** One coat application -- insulating
and finishing. Slow drying, rough texture -- insulating and filling. Used
over basic insulation -- Smooth finish, usually 3 to 6 mm (1/8" to 1/4")
thick application.
Notes:
1. Temperature range and K-Factor data were compiled from current manufacturer's
published literature. Consult specific manufacturer's data for application
methods.
2. Special attention must be given to high humidity / high temperature
applications, specifically vapor retarder systems.
** See manufacturers' data for K-factor.
