1. Product Description
Thermal Ceramics Pyroscat
® Duct Wrap XL is a flexible
blanket composed of high temperature fibers classified for
applications to 2192°F (1200°C) and fully encapsulated in a
durable glass fiber reinforced foil facing for easy handling and
installation. Pyroscat Duct Wrap XL is UL and ULC Listed for
1 and 2 hour fire resistive enclosure protection, zero clearance
for kitchen exhaust ducts, electrical circuit protection, and as a
component in UL firestop designs for fire resistance rated
floors, ceilings, and walls. The core fibers in Pyroscat Duct
Wrap XL are manufactured using Thermal Ceramics patented
Superwool
® fiber which is an alkaline-earth silicate wool with
low biopersistence and therefore increased safety for
installers. Pyroscat Duct Wrap XL is under UL’s Follow-Up
Service Program to ensure the consistent quality essential to
this life-safety application.
