Knauf ET Blanket
Description
Knauf ET Blanket 1000° is a lightweight thermal insulation
blanket (1.1 PCF, 17.6 kg/m3) made from highly
resilient, inorganic glass fibers bonded by a high-temperature
thermosetting rsin.
Application
Knauf ET Blanket 1000° is for industrial heating equipment to
1000°F (538°C), such as industrial furnaces, panel systems, marine
applications and irregular surfaces.
Features and Benefits
Excellent Thermal Properties
- Low thermal conductivity ratings to 1000°F (538°C).
- Increases system efficiency and decreases fuel usage.
Low-Cost Installation
- Lightweight, and easy to handle and fabricate.
- Flexibility makes it ideal for flat or irregular surfaces.
Damage Resistant
- Tough and resilient.
- Resists damage in shipment, and during and after
installation.

Water Vapor Sorption (ASTM C 1104)
Temperature Limit (ASTM C 411)
Resists Microbial Growth (ASTM C 1338)
- No growth.
- Will not rot or sustain vermin.
Non-Corrosive (ASTM C 665)
- Will not accelerate corrosion of steel.
- Complies to stress corrosion requirements of ASTM C 795,
MIL-I-24244C, and NRC Reg. Guide 1.36.
Application and Specification Guidelines
Precautions
- During initial heat-up to operating temperatures above 350°F
(177°C), a slight odor and some smoke may be given off as a portion
of the bonding material used in the insulation begins to undergo a
controlled decomposition.
- If natural convection is not adequate in confined areas, forced
ventilation should be provided in order to protect against any
harmful fumes and vapors that might be generated.
Storage
- Protect material from water damage or other abuse. Protect from
welding sparks and open flame. The material may be stored outside
if the packaging is not damaged.
Preparation
- Apply the product on clean, dry surfaces.
Application
- There is no heat-up cycle required for Knauf ET Blanket
1000°.
- The product should be secured with welded pins and washers, or
studs and washers, and covered with sheet metal. An alternate
method entails covering the insulation with a metal mesh and
insulating cement, canvassing, and painting.
- Pins and washers shall be located a maximum of 4" (102 mm) from
each edge and spaced no greater than 16" (406 mm) on center.
- Care should be taken to avoid over compressing the insulation
with the retaining washer.
- Dual-layer installation with staggered joints is recommended
for applications where temperatures meet or exceed 450°F
(232°C).
Caution
Fiber glass may cause temporary skin irritation. Wear
long-sleeved, loose-fitting clothing, head covering, gloves, and
eye protection when handling and applying material. Wash with soap
and warm water after handling. Wash work clothes separately and
rinse washer. A disposable mask designed for nuisance type dusts
should be used where sensitivity to dust and airborne particles may
cause irritation to the nose and throat.
