(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 – 100oF where temperatures are > 5oF 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 – 100oF where temperatures are > 5oF 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 – 100oF where temperatures are > 5oF 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.
