Duct Installation 

GENERAL INSTALLATION 

Grease Duct and 1& 2 hour 

Ventilation Air Duct Systems 

• Quickwrap ONE Fire Resistant duct insulation 

wrap constructed as follows: 

- single layer installation using either: 

Quickwrap ONE Butt Wrap "Double 

Banding Method" 

Quickwrap ONE "Pinning Only" Butt 

Wrap Method 

Quickwrap ONE "Overlap" Method 

- for 2 or 3 sided systems use either: 

Quickwrap ONE "2 or 3" Sided Pinning 

Only Method 

Quickwrap ONE "2 or 3" Sided Banding 

Method 

Grease Duct System 

• maximum 40" x 40" (1600 in²) rectangular, 

square or round #16 gauge grease duct 

assembly 

Ventilation Air Duct System 

• maximum 2915 in² rectangular, square or round 

#26 gauge or greater air duct assembly rated for 

maximum 300 Pa negative pressure within the 

duct 

• complying with SMACNA or NFPA 90A 

requirements 

Support Rods & Cradles 

• minimum 3/8” steel threaded rod & 1½" x 1½" x 

3/16" steel angle cradles for ductwork not 

exceeding 160 in² in area 

• minimum ½" steel threaded rod & 2" x 2" x ¼" 

steel angle cradles for ductwork exceeding 160 

in² in area 

• support rods to be anchored to concrete using 

pass thru method with a nut & washer on the 

top of the concrete slab or by using suitable 

carbon or stainless steel masonry anchors 

penetrating a minimum 2" depth into the 

concrete slab 

• maximum distance of 60" allowed between noninsulated 

duct supports. 

Note: 

As required by site conditions, it is acceptable to 

encase the cradle support assembly along with the 

duct within the Quickwrap ONE insulation (i.e. 

cocoon wrap) during the installation. A slit is 

allowed in the duct wrap in order to position around 

the threaded rod. Slit must be repaired and sealed 

using Quickstop Acrylic Latex Sealant to a 

minimum depth of ¼" with a bead also placed 

around the circumference of the support rod. 

Seams can be sealed using any combination of the 

approved installation methods. 

Banding 

(not required with "Pinning Only" method) 

• ½" stainless steel banding for all grease duct 

and 2-hour ventilation air duct systems installed 

as outlined in Quickwrap ONE "Double 

Banding" Method and Quickwrap ONE 

"Overlap" Method 

• ½" wide carbon steel banding for 1 hour 

ventilation air duct systems 

Firestop 

• minimum 4" depth of 4 lb/ft³ (or heavier) mineral 

wool insulation or Quickwrap ONE fiber firmly 

packed into 1 or 2 hour rated concrete 

• full depth of mineral wool or Quickwrap ONE

fiber (less caulking depth) into framed gypsum 

wall or framed wood floor/gypsum ceiling 

• assemblies are to be topped with Quickstop 

Acrylic Latex Sealant to a min. depth of ¼" on 

top of floor or both sides of wall assembly 

Quickwrap ONE 'Double 

Banding' Method 

• maximum annular space of 7 ½" between duct 

and floor or wall substrate is allowed. 

• see Intertek Testing Services (ITS) listing 

EWC/PHV 120-01 for additional firestop details. 

Gypsum Shaft Transition (if required) 

• should a transition be required from a gypsum 

shaft system to a Quickwrap ONE duct wrap 

system the annular space around the duct and 

the shaft must be filled with a minimum of 4" 

depth of Quickwrap ONE insulation and 

topped with a ¼" depth of Quickstop acrylic 

latex firestop sealant flush with the surface of 

the gypsum 

• Quickwrap ONE Duct insulation used for 

wrapping the duct must firmly abut the firestop 

Installation 

• requires one (1) layer of Quickwrap ONE 

(QW1) fire resistant duct insulation in 

accordance with manufacturer's instructions for 

grease duct systems only 

• all cut ends of insulation to be repaired with 

aluminum tape 

• seams installed by providing 1" compression on 

each side of the wrap, in all seam directions 

1) Circumferential joint to be compressed by 1" 

on each side of wrap width. For example, 

24" of duct wrap material are used per 22" of 

duct length. 

2) Add an extra 2" of QW1 to required length 

for completion of longitudinal joint. 

• any visual gaps no greater than ½" can be 

remedied by adding a piece of Quickwrap 

ONE which is 1" greater than the gap and 

compressed into place. Additional pins or bands 

must be added at these points to increase 

installation integrity
