Thermoseal Spray Foam InsulationProduct Name
ThermoSeal 500 is the registered trademark of for its .5lb light density, open cell foam insulation.

Product Description
ThermoSeal 500 is a semi-rigid, totally water blown, .5lb light density polyurethane foam insulation system which simultaneously insulates and air-seals your building structure. ThermoSeal 500 is designed to make homes more energy efficient, quieter, healthier and more comfortable. ThermoSeal 500 is applied as a liquid spray which expands approximately 100 times its initial mass and cures within seconds into a semi-rigid mass. ThermoSeal 500 fills all building cavities completely sealing all cracks, crevices, and voids where air loss and infiltration are most common. If needed, excess material is easily trimmed off leaving a surface ready for drywall.

Thermal Performance
Thermal resistance R/in.
ASTM C518: R3.83hr.ft2 °F/BTU
Average insulation contribution in stud wall:
2”x4”=R13.3 2”x6”=R20.9

ThermoSeal 500 provides greater R value performance than other equivalent R value insulation materials which are air permeable such as fiberglass. ThermoSeal 500 does not lose R value due to wind, ageing, convection, air infiltration or moisture. An R value fact sheet is available upon request.

E84, E96, E283 tests results were conducted by Intertek a 3rd party testing laboratory. DISCLAIMER: Information contained herein is, true and accurate, but all Air Permeance/Air Barrier
ThermoSeal 500 fills any shape cavity including all voids, cracks, and crevices adhering to multiple substrates such as wood, metal, and concrete creating a system with very little air permeance. With ThermoSeal 500 no additional interior or exterior air infiltration protection is required.

ASTM E283 Air Leakage
.00015 ft3/s.ft2 @ 75Pa (25mph wind)
Sustained Wind Load
60 minutes@1000 Pa (90mph wind)
No Damage
Gust Wind Load Test
@3000 Pa (160 mph wind)
No Damage

Water Vapor Permeance
ThermoSeal 500 is water vapor permeable and will allow structural moisture to escape. For situations requiring a vapor barrier the use of low vapor permeable paint on the interior of drywall is an option.
Water Vapor Transmission Properties:
ASTM E96 data
5.51perms @ 3.5”

Water Absorption
ThermoSeal 500 is water repellent, will not wick, and does not exhibit capillary properties. Water may be forced into the foam under pressure because of its open cell structure, and will self drain by gravity rather than travel horizontally or vertically as in closed celled foams. Once the foam has dried its thermal performance is at full performance.

Actual performance will likely be superior to the above results based on ThermoSeal’s ability to control air permeation.

Burn Characteristics
ThermoSeal 500 is a Class I insulation and shall be separated from its inhabitants by a 15 minute approved thermal barrier. ThermoSeal 500 shows less flame propagation than some Kraft faced fiberglass insulation and may be left exposed in attics and crawl spaces. ThermoSeal 500 might be consumed by flame but will not sustain flame upon removal of the flame source. ThermoSeal 500 will not melt or drip. ThermoSeal 500 must be installed in accordance with all applicable building.
ASTM E84 Surface Burning Properties
Flame Spread @ 6” <= 25
Smoke Developed @ 6” <= 250
Class 1 rating
Fuel Contribution none
ASTM 2863 Oxygen Index 25%

Compressive and Tensile Strength
ThermoSeal 500 has favorable compressive and Tensile strength properties for light density foam.
ASTM D1623 Tensile Strength 4.3 psi
ASTM D1621 Compressive Strength 5.1psi

Open Cell Content
ThermosSeal 500 is considered an open cell foam insulation:

Electrical Wiring
ThermoSeal 500 is chemically compatible with all 14/3, 12/2 and other similarly coated electrical wirings. For knob and tube wiring please seek the approval of your local building inspector.

Bacterial and Fungal Evaluation
ThermoSeal 500 is not a source of food for mold, insects or rodents. It has no nutritional value. ThermoSeal 500 reduces the introduction of moisture, food, and mold spores into the building envelope significantly more than traditional insulation such as fiberglass, cellulose and other non-sealants which do not provide an air barrier.

Environment/ Health/ Safety
ThermoSeal 500 contains no CFC’s HCFC’s , formaldehyde, or volatile organic compounds. Following installation there will be a 24-48 hour occupancy window before the odors, emissions and gasses have dissipated to a habitable level for individuals highly sensitive to the materials installed.
ThermoSeal 500 is not intended for exterior use or is not to be installed within 2”of heat emitting surfaces where heat dissipated exceeds 185°F.

Component A- 550 lbs of Isocynate stored in a a 55 gallon container outlined above. Component ‘A’ must be protected from freezing or deemed useless.
