PRODUCT	BASE FOAM TYPE	BASE FOAM THICKNESS (inches)	BASE FOAM DENSITY (lbs/ft³)	INSTALLATION
Firestable® FS 2.0 A) Alternate	No Base Foam	Firestable FS 2.0 at 2.5 lbs/ft³ nominal density target from 1’’ to 9’’ installed thickness.		Ensure the substrate is dry and clean of debris and dust. Firestable FS 2.0 is applied in a single pass up to 2.5 inches thickness, at 2.5 lbs/ft³ target density (2.3 – 2.8 lbs/ft³ required). FS 2.0 is applied to ensure a continuous unbroken surface across walls and ceilings. Installation of Firestable FS 2.0 to be done at ambient temperatures of 30 – 100^oF where temperatures are > 5^oF above the dew point to ensure bond to substrate.
Firestable® FS 2.0 B) Equivalent		Firestable FS 2.0 at 2.5 lbs/ft³ nominal density target at ≥ 2.5 inches where installed per NFPA 275 above.
Firestable® FS 2.0	Thermoplastic	See NFPA 275 Above		Ensure base foam is dry and clean of debris and dust. Firestable FS 2.0 is applied in a single pass to minimum 2.5 inches thickness, at 2.5 lbs/ft³ target density (2.3 – 2.8 lbs/ft³ required). FS 2.0 is applied to ensure a continuous unbroken surface across walls and ceilings to ensure underlying foam protection with no voids or gaps present. Installation of Firestable FS 2.0 to be done at ambient temperatures of 30 – 100^oF where temperatures are > 5^oF above the dew point to ensure bond to base foam layer.
Firestable® FS 2.0	Thermosetting	See NFPA 275 Above		First pass of thermosetting foam base layer is applied to maximum thickness and density described in NFPA 275 above. The base layer is to be allowed to condition to ambient temperature and confirmed to be clean and dry prior to application of Firestable FS 2.0. Following, at minimum a single pass of Firestable FS 2.0 is to be applied at 2.5 inches thickness, at 2.5 lbs/ft³ target density (2.3 – 2.8 lbs/ft³ installed required). FS 2.0 is applied to ensure a continuous unbroken surface across walls and ceilings to ensure underlying foam protection with no voids or gaps present. Installation of Firestable FS 2.0 to be done at ambient temperatures of done at ambient temperatures of 30 – 100^oF where temperatures are > 5^oF above the dew point to ensure bond to base foam layer.

For application the manufacturers installations instructions must be followed, foam MUST be cured and cooled to ambient conditions, all surface preparation should be carried out in accordance with good application practices. Firestable® FS 2.0 should be installed by qualified contractors to ensure product performance.
Firestable FS 2.0 is to be installed at target thicknesses noted, in the density tolerances shown for use as a thermal barrier.
