Knauf ET Board with ECOSE® Technology
Description
Knauf Elevated Temperature Board 850° with
ECOSE
®
Technology is a lightweight insulation (2.8 pcf, 44.9
kg/m
3) bonded with ECOSE Technology. It is a semi-rigid,
board-like form with superior handling properties andinsulating
effectiveness at minimum cost.
ECOSE Technology
ECOSE Technology is a revolutionary new binder
chemistry that makes Knauf Insulation products even
more sustainable than ever. It is based on rapidly
renewable bio-based materials rather than nonrenewable
petroleum-based chemicals traditionally used n fiber glass
insulation products. ECOSE Technology reduces binder embodied
energy and does not contain phenol, formaldehyde, acrylics or
artificial colors.
Application
Knauf Elevated Temperature Board 850° with ECOSE
Technology is used for boiler walls, hot precipitators, hot
ductwork, cylindrical tanks, towers, stacks, and industrial
ovens.
Features and Benefits
Excellent Thermal Properties
Low Installed Cost
- Lightweight.
- Easy to fabricate.
- Sizes up to 4' x 10' available.
Polybag and Sleeve Packaging
- Damage resistant.
- Reduces storage space.
Resilient Fiber Glass
- Maintains integrity at elevated temperatures.
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. Cartons are
not designed for outside storage. Vacuum packaged material can be
stored outside if care is taken not to puncture the polybag.
Preparation
- Apply the product on clean, dry surfaces.
Application
- All insulation joints must be firmly butted. Mount flush
against surfaces to 850°F (454°C) or use in panels mounted away
from operating surface.
- Knauf ET Board 850° is designed to be applied over welded pins
and/or studs up to 1/2" (13 mm) in
diameter. The board is to be held in place by speed washers,
tension clips, or metal mesh reinforcement.
- Installation method should not compress material beyond maximum
5% at any point.
- Pins and studs shall be located a maximum of 4" (102 mm) from
each edge and spaced no greater than 16" (406 mm) on center.
- In temperatures over 550°F (288°C) and designed thickness over
3" (76 mm) dual layer application with
staggered joints is recommended. Install thickness recommended by
Knauf or NAIMA 3E Plus program.
- Finish surface with metal cover, or with insulating cement and
canvas.
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.
Fiber Glass and Mold
Fiber glass 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.
