Elevated Temperature Blanket

Elevated Temperature Blanket

Knauf Insulation ET Batt 1000° and Knauf ET HD Blanket 1000° with ECOSE® Technology are semi-rigid thermal insulations (1.6 pcf, 25.6 kg/m3), bonded with ECOSE Technology.

ECOSE® Technology

ECOSE Technology is a revolutionary binder chemistry that enhances the sustainability of our products. The “binder” is the bond that holds our glass mineral wool product together and gives the product its shape and brown color. ECOSE Technology is a plant-based, sustainable chemistry that replaces the phenol/formaldehyde (PF) binder traditionally used in glass mineral wool products. Products using ECOSE technology are formaldehyde-free and have reduced global warming potential when compared to our products of the past.

Application

ET Batt 1000° and Knauf ET HD Blanket 1000° with ECOSE Technology are used in high-temperature marine applications, industrial furnaces, boilers, vessels and industrial ovens, where lighter-weight insulation is needed or flexible and/or semi-rigid high-temperature insulations are needed for irregular surfaces.

Features and Benefits

Excellent Thermal Properties

  • Low thermal conductivity.
  • Increase system efficiency and decrease fuel usage.

Low-Cost Installation

  • Lightweight and easy to handle and fabricate.
  • Flexibility makes them ideal for flat or irregular surfaces.

Damage Resistant

  • More resistant to abuse than standard ET Blanket.
  • Tough and resilient.
  • Resist damage in shipment, and during and after installation.

Custom Sizes

  • All items are available in made-to-order sizes.

Indoor Air Quality

  • Certified by UL Environment for indoor air quality (IAQ) as low emitting products and where noted, have achieved the more stringent GREENGUARD Gold certification and verified to be formaldehyde-free.

Sustainability

  • Carbon negative: meaning Knauf insulation products used for thermal insulating purposes recover the energy that it took to make them in just hours or a few days, depending on the application. Once installed, the product continues to save energy and reduce carbon generation as long as it is in place.

Fiber glass insulation with ECOSE Technology

  • contains three primary ingredients:
    • Sand, one of the world’s most abundant and renewable resources
    • Post-consumer recycled bottle glass
    • ECOSE Technology which reduces binder embodied energy by up to 70%

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 Batt 1000° and HD 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 500°F (260°C).
  • When using the products at 1000°F (538°C), it is recommended that no more than 6" (152 mm) thickness be used.

Caution

Glass mineral wool 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 or throat.

Glass Mineral Wool and Mold

Glass mineral wool insulation will not sustain mold growth. However, mold can grow on almost any material when it becomes wet and contaminated. Carefully inspect any insulation that has been exposed to water. If it shows any sign of mold it must be discarded. If the material is wet but shows no evidence of mold, it should be dried rapidly and thoroughly. If it shows signs of facing degradation from wetting, it should be replaced.
