All Hilti Firestop Sealants listed above are well below the requirement for LOW-EMITTING
MATERIALS, Section 4.1, Adhesives & Sealants and Section 4.2, Paints & Coatings.
Please make sure that you are submitting MSDS sheets that are current.  There were some older MSDS
sheets that overstated VOC values as exceeding the 250 g/l threshold that is required for the project to
meet LEED™ Credit 4.1 and / or 4.2.
Some of the LEED™ credit (point) requirements other than Credits 4.1 and 4.2 discussed above call
for significant percentage (e.g. 10%, 20%) of the building’s construction materials to meet various
requirements.  Some of these requirements could potentially be thought of as applying to firestop
products.  Practically speaking, there is absolutely no need for firestop buying decisions to be affected
by these requirements.  Typically FIRESTOP products used represent less that .02% (2/10 of one
percent) of the construction materials used.  Therefore even if we met every requirement in LEED™,
the contribution to the LEED™ points that could be provided by the relatively tiny weight or volume
of firestop products would be essentially inconsequential.  From a practical standpoint, the LEED™
credit requirements that call for a large percentage of building construction materials to meet certain
requirements need to be met by the proper purchase of bulk-type material (e.g. concrete, steel, wood,
flooring, roofing, site fill).
Along the line of these large percentage requirements, one LEED™ section that is sometimes thought
to apply to Firestop Sealants is Materials & Resources.  This is sometimes referred to as the “most
commonly misunderstood credit”.  There are a few credits in this section that firestop sealants often get
categorized into but possibly should not.  This is because for the project as a whole, firestop is limited
in its scope and this section does not specifically call out firestop products.
In the Material & Resource section, Credit 2.1 and 2.2, Construction Waste Management the intent is
to recycle a specific percentage of the construction waste on a project.  Hilti product packaging is
100% recyclable and is produced with recycled materials.
In the Materials & Resources section, Credit 4.1 and Credit 4.2, Recycled Content request that a 5%
and 10% respectfully of building material contain recycled materials.  Hilti Firestop sealants are not
made with recycled materials; this is the nature of firestop products.
In the Materials & Resources section, Credit 5.1 and Credit 5.2, Regional Materials, call for 20% and
50% respectfully of the total building products be manufactured within a 500 mile radius of the
project.  Currently only one Hilti firestop sealant, CP672 is manufactured in the United States. Every
other product is manufactured in Europe.
