EcoSeal™ Water-Based Elastomeric Sealant
Description
Knauf Insulation EcoSeal™, the latest
technology in home energy solutions, is a fast drying, water-based
elastomeric spray that seals penetrations and joints in the
building envelope, including exterior walls, attics and floors.
EcoSeal dries to a flexible tough film and has great bond strength
with low odor and is extremely low in V.O.C’s. EcoSeal should be
used with Knauf Insulation EcoBatts® or Knauf
Premium Blowing Insulation. Together, they are known as the EcoSeal
System. The EcoSeal system forms an effective, continuous and
affordable air and thermal barrier for the building envelope.
Kit Description
Knauf Insulation has collected all the components in a
convenient kit that contractors will need to start sealing
immediately. These components include a GRACO Ultra Max 795 Airless
Sprayer with 50 feet of hose, a 6 foot whip hose, spray gun, two
nozzle extensions, tip guard and two spray tips. Also included is a
hose reel, a digital display and an adapter/plug to enable the
usage of two hoses simutaneously. Replacement parts and other
accessories can be purchased at most paint supply stores.
Application
Knauf Insulation EcoSeal is applied
directly from the bucket, with no thinning or mixing. Using an
airless sprayer, EcoSeal’s short curing time allows the
installation of EcoBatt® Insulation or Knauf Premium
Blowing Insulation in just a few hours, in most cases. Once cured,
it remains flexible over a wide range of temperatures. EcoSeal is
designed to be installed by trained applicators.
Affordable
performance.
- EcoSeal sealant combined with EcoBatt Insulation or Knauf
Premium Blowing Insulation is a lower cost, more sustainable
alternative to foam insulation while delivering equal or superior
performance characteristics.
Total envelope
solution.
- Delivers air flow resistance to the
whole structure, not just the cavities.
- Seals areas traditional spray foams
cannot. Trade-friendly, no schedule delays.
- Unlike many foams, EcoSeal does not
involve mixing hazardous chemicals at the jobsite, nor does it
generate hazardous off-gassing during cure.Therefore, EcoSeal is
safe to spray and dries quickly—so other trades stay on site and on
schedule.
Significant acoustical
Benefits
- EcoSeal, when used in combination
with Knauf Insulation EcoBatts or Knauf Premium Blowing Insulation,
provides superior acoustical performance.
EcoSeal fills the
gaps
- EcoSeal penetrates gaps as small as
1/8". It coats the face of gaps smaller than this, like the joint
of double plates, sealing the joint. Gaps larger than 3/8" should
be backfilled prior to sealing with EcoSeal.
Few temperature
limitations for storage and appllication
- It should be stored in a dry location
with a temperature between 35° and 120°F.
- Can be applied from 20° to 115°F, as
long as the sealant is fluid in the bucket.
Easy
cleanup
- EcoSeal cleans up with water; no
chemical solvents required.
Indoor Air Quality
- Certified for indoor air
quality as a low emitting product by The GREENGUARD
Environmental Institute to both the GREENGUARD Certification
Program™ and the more stringent GREENGUARD Children and
SchoolsSM standard.
Specification
Compliance
- Meets or exceeds all state and
federal VOC requirements for architectural sealants
- VOCs: <0.3 grams/liter (less
water, less exempt compounds-calculated)
- GREENGUARD™ Certified
- GREENGUARD for Children and
SchoolsSM Certified
Technical
Specifications Shelf Life
- 18 months in unopened
contatiners.
Coverage
Rate
- Approximately 2000 linear feet per
bucket when applied at a ¼" bead.
Temperature
Limits
- Application 20°F to 115°F
- Storage: 35°F to 120°F
Note: Protect from
freezing. If frozen, completely thaw prior to use. Do not attempt
thawing by mixing, stirring, blending or agitating. Material must
be allowed to thaw completely and be above freezing when sprayed.
Passes five freeze-thaw cycles.
Surface Burning
Characteristics
- Does not exceed 25 Flame Spread, 50
Smoke developed when tested in accordance with ASTM E 84, UL 723
and CAN/ULC S102-M88.
Sound Transmission
(Acoustics)
- In comparative testing per ASTM E90,
EcoSeal provided a significant sound trans- mission reduction (10
dB) versus unsealed walls. For more information, comparing EcoSeal
to alternative treatments, see www.knaufinsulation.us.
Cleanup
- Use water and soap. Cured materials
need to be mechanically removed. EcoSeal disposal should be treated
the same as disposal of latex paint. Clean buckets are
recyclable.
Weight
- Approximately 60 lbs. (27 kg.)
Microbial
Growth
- Does not support microbial
growth.
- Excellent resistance to mold and
mildew.

Packaging
Knauf Insulation EcoSeal sealant is
packaged in a 5 gallon pail. It ships 36 pails per pallet.
Installation of
the EcoSeal System
While the EcoSeal System is
relatively simple, Knauf Insulation offers training online at
www.knaufinsulation.us
to ensure installers understand all of the important details
necessary to achieve optimal performance. An Application Guideline
Manual is also available online or in hard copy form. In addition,
further training can be arranged through your Knauf Insulation
sales representative. Knauf Insulation recommends that contractors
with EcoSeal certification training be used wherever
available.
