Component Description Steel studs 3-5/8 in. (92 mm) deep 20 ga galvanized steel spaced 24 in. (609 mm) on center, secured to the track with self-drilling screws. Interior Gypsum Board Type X gypsum board, 5/8 in. (15.9 mm) thick, listed by an
approved agency as complying with ASTM C1396. 4 ft.
(1219 mm) wide, attached to the interior face of steel studs
with 1-5/8 in. (41 mm) long self-tapping screws spaced 8 in.
(203 mm) OC around the perimeter and 12 in. (304 mm) OC
in the field. Joints were oriented vertically and covered with
paper tape and joint compound.Stud Cavity Insulation Accella EcoBay CC 2.0 pcf spray foam insulation installed at
a thickness of nominal 3 in (76 mm) within the stud cavities,
leaving a nominal 5/8 in (15.9 mm) air gap between the
surface of the insulation and interior gypsum board.Exterior Gypsum Board Exterior gypsum board, 5/8 in. (15.9 mm) thick complying
with ASTM C1777 attached to the exterior face of steel studs
with 1-5/8 in. (41 mm) long self-tapping screws spaced 8 in.
(203 mm) OC around the perimeter and 12 in. (304 mm) OC
in the field. Joints not treated.Horizontal Z Girts 20 ga.non-perforated steel z girts with a depth of 3 in
(76mm) and 1 ½ in (38mm) flanges were installed
horizontally over the exterior sheathing, spaced at 4 feet
(1219 mm) OC.Exterior Insulation Accella EcoBay CC 2.0 pcf insulation sprayed at a thickness
of nominal 2 in (51 mm) directly onto the exterior sheathing,
and between the horizontal z girts. A nominal 1 in (25.4 mm)
air gap between the surface of the insulation and outer
flange of the z girts.Spray Coating DC 4000 spray coating was applied at a nominal 60 mil wet
thickness directly onto the exterior Accella EcoBay CC
insulation. Coating sprayed applied onto the entire
assembly; Note additional coats may need to be applied to
obtain final desired 60 mil wet thickness.Steel Corrugated Panels 0.042 inch (1.1 mm) thick, 1-1/2 in (38 mm) deep steel
corrugated panels 3 feet (914mm) wide fastened to the
horizontal z girtsThe following outlines DC4000-2k water based non-intumescent coating ratings determined in accordance with NFPA 286
Standard Model Rating NFPA 286 DC 4000-2K @ min 60 WFT over 5.5” for vertical surfaces & 9.5” for horizontal Surfaces Seal Tite CC+ closed Cell Spray Applied Polyurethane Foam
(≤ 2.2 lbs/ft3)Complies with Acceptance Criteria in Annex C of NFPA 286-15, 2009 IBC section 803.1.2
2009 IRC section 316.6 and 2015 NFPA 101 section 10.2.3.7.2Uses:
DC4000-2K Fire Protective Coating is a two component, weather resistant,
water based non-intumescent coating, for use, on spray applied foam insulation.
When DC4000-2K is applied to spray foam insulation, the coated foam plastic
assembly may be left exposed as the interior finish in lieu of a prescriptive
thermal barrier.
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 painting practices and the
DC4000-2K must be thoroughly mixed before being spray applied.
The mil thickness should to be checked during installation to ensure minimum
noted thickness are maintained.See Manufactures Approved Design and Installation Documents.
