Knauf ET Blanket

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.

  • 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.

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.
