Product Name
ThermoSeal 1200 is the registered trademark of for its 1.2lb medium density, open cell foam insulation.

Product DescriptionThermoseal Spray Foam Insulation
ThermoSeal 1200 is a semi-rigid, totally water blown, 1.2lb medium density polyurethane foam insulation system which simultaneously insulates and air-seals your building structure. ThermoSeal 1200 is designed to make homes more energy efficient, quieter, healthier and more comfortable. ThermoSeal 1200 is applied as a liquid spray which expands approximately 70 times its initial mass and cures within seconds into a semi-rigid mass. ThermoSeal 1200 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: R4.89hr.ft2 °F/BTU
Average insulation contribution in stud wall:
2”x4”=R17.1 2”x6”=R26.8
ThermoSeal 1200 provides greater R value performance than other equivalent R value insulation materials which are air permeable such as fiberglass. ThermoSeal 1200 does not lose R value due to wind, ageing, convection, air infiltration or moisture. An R value fact sheet is available upon request.

Air Permeance/Air Barrier
ThermoSeal 1200 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 1200 no additional interior or exterior air infiltration protection is required.
ASTM E283 Air Leakage
TBD ft3/s.ft2 @ 75Pa (25mph wind)
Sustained Wind Load
60 minutes@1000 Pa (90mph wind)
Gust Wind Load Test
@3000 Pa (160 mph wind)

Water Vapor Permeance
ThermoSeal 1200 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
3.05@ 3.5”

Water Absorption
ThermoSeal 1200 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.

Acoustical Properties
Performance in a 2”x 6” wood stud wall.
ASTM E413 STC Sound Transmission Class 49
Hz. Freq. 125 250 500 1000 2000 4000
Trans. Loss 15 26 30 41 44 46
ASTM C 423
NRC Noise Reduction Coefficient = .70
Hz. Freq. 125 250 500 1000 2000 4000
Absorption .20 .49 .84 .69 .74 .72
Actual performance will likely be superior to the above results based on ThermoSeals ability to control air permeation.

Burn Characteristics
ThermoSeal 1200 is a Class I insulation and shall be separated from its inhabitants by a 15 minute approved thermal barrier. ThermoSeal 1200 shows less flame propagation than some Kraft faced fiberglass insulation and may be left exposed in attics and crawl spaces. ThermoSeal 1200 might be consumed by flame but will not sustain flame upon removal of the flame source. ThermoSeal 1200 will not melt or drip. ThermoSeal 1200 must be installed in accordance with all applicable building codes.
ASTM E84 Surface Burning Properties
Flame Spread @ 6” <= 25
Smoke Developed @ 6” <= 450
Class 1 rating
Fuel Contribution none
ASTM 2863 Oxygen Index 25%
Compressive and Tensile Strength
ThermoSeal 1200 has favorable compressive and Tensile strength properties for light density foam.
ASTM D1623 Tensile Strength 15.2 psi
ASTM D1621 Compressive Strength 10 psi
