Type V Pipe Insulation That Beats The
Heat and and Protects with Exceptional
Compressive Strength
ProRox PS 980
NA
is a lightweight, mandrel-wound
preformed Type V pipe insulation designed specifically 
for high-temperature steam and process pipe systems. 
ProRox PS 980
NA
is engineered to deliver exceptional
compressive strength without susceptibility of 
breakage and the dust associated with calcium 
silicate for a cleaner, safer working environment.
Made of stone wool, this proven, cost-effective 
product is ideal for steam and process pipe systems 
operating at temperatures up to 1400 °F (760 °C), 
where energy conservation, personnel protection 
and fire control are concerns.
Benefits
■
ASTM C547 Type V pipe insulation (Standard
Specification for Mineral Fibre Pipe Insulation)
■
Operating temperature up to 1400 °F (760 °C)
■
Excellent compressive strength properties ideal for
areas subject to heavy mechanical loads
■
Easier cutting at point of installation; no band 
saw required
■
Virtually no dust to keep work environments cleaner
■
Fire resistant; non-combustible, with melting point of 
approx. 2150 °F (1177 °C)
■
Top thermal performance; use less product
■
Smaller diameters compared to calcium silicate, 
reducing jacketing costs
■
Range of thicknesses and sizes, from ½” to 34” NPS
Compliance
Fire Resistant
ProRox PS 980
NA
is non-
combustible, resisting fire and 
delaying fire spread for added 
margins of worker and plant 
safety.
Water Repellent
The stone wool structure 
repels water and aids in 
draining to protect pipes and 
does not promote fungi or 
mildew growth.
Superior Compressive Strength
The dense wool structure 
provides strength to withstand 
high traffic in plants.
Fast, Easy Installation
ProRox PS 980
NA
requires
nothing more than a serrated 
knife for precise cuts that can 
be made easily at the point of 
installation, reducing waste 
and manpower hours.
