I. Subject: Spunstrand Undersiab Duet.
II. Description: Spunstrand duet is constructed with lilanknt- wound.
polyester resin - impregnated, continuous fiberglass strands wound over an
inner liner of a UL- listed Class I duct liner identified as FB 1266 ASJ Foil-
Scrim-Craft liner. manufactured by the Compuc Corporation. Nctcung.
New Jersey. The duet is manufactured in 4 -inch through 36-inch diameters.
The 4 -inch through 24 -inch ducts are available in 20 -foot lengths and the
larger sires in 1U -foot lengths. Straight sections of the duet are joined by
using an internal sheet metal sleeve of No. 26 gauge to No. 22 gauge
' galvanized steel, depending upon the duet size. The sleeve is first screw
attached to one section of pipe to be joined using no fewer than three equally
spaced sheet metal screws for ducts through 12 -inch diameter, four screws
for ducts 14 -inch through 24 -inch diameter and five screws for ducts larger
than 24 inches. A bead of Presstite No. 579.6 Waterproof Mastic is applied
around the circumference at the end of the duct. The adjacent section of duct
is slipped over the sleeve and pressed tightly against the mastic, forming a
waterproof seal. Sheet metal screws then secure the second section of duct
to the sleeve. Finally, the joint is wrapped with Nashua Type 357 duct
closure tape. As an alternate to the Presstitc No. 579.6 mastic and Nashua
357 duet tape, 3- inch -wide Hardcast, Inc. Peal 'n' Seal instant sealant tape
provided by Peabody Spunstrand may be used.
Standard fittings similarly constructed, such as ells, wycs, tees, crosses.
branches, concentric and eccentric reducers are available. Attachment
procedures of these fittings are similar to those for straight sections.
Trenches arc dug for the duct in the desired locations, allowing for cover
around the duct for a minimum of 4 inches of pea gravel or other select fill
material approved by the building official. The trench may be lined with
polyethylene film or other approved moisture barrier before the fill is placed
Report No. 2488
March, 1983
in the trench. After all joint connections arc made as described above and
the duct system is lowered into position, back - filling is completed. A
concrete slab is poured over the duct so that the top of the duet has a
minimum cover of 21/2 inchcs.
The ducts arc designed for use in systems with a maximum rated positive
pressure equivalent to t0 -inch water column, a maximum rated negative
pressure of 4.8 -inch water column and a maximum velocity of 250!1 feet let
minute.
identification: Each length of duct, including the fittings, is identified
by a label containing the manufacturer's name, address, the ICBO report
number, maximum positive and negative pressures, rated velocity, operat-
ing temperature and 'the name of the inspection agency.
III. Evidence Submitted: Reports of tests conducted in accordance
with applicable portions of Uniform Mechanical Code Standard No. 10.1,
installation instructions and quality control manual are submitted.
Findings
IV. Findings: That the Spunstrand Underslab Duct complies with

INSTALLATION INSTRUCTIONS FOR
SPUNSTRAND UNDERSLAB AIR DUCT
1 01 6
Peabody Spunstrand
General
Spunstrand Duct is a semi -rigid reinforced thermosetting resin product designed to deflect
approximately 5% under external load without structural damage. The performance of the
duct is affected by the amount of strain introduced into the duct wall from internal pressure,
external loads and the resulting deflection of the duct with respect to its wall thickness.
It is important to recognize the need for care in handling the duct during the Installation
process and to properly provide uniform support for the duct by carefully placing the backfill
material under and around the duct, Large ducts will usually require internal support dur-
ing the backfilling process and until all external soil loads have stabilized.
When installed underground, the load of the soil above the duct tends to flatten the duct
and make it wider. As the duct tries to widen, the walls push into the soil at the sides
developing a resistance that helps support the vertical load, The higher the soil resistance,
the less the duct will deflect. Proper installation techniques are necessary to prevent ex-
cessive deflections and the resulting failure of the duct by buckling.
Trench Construction
The surface at the bottom of the trench should be continuous, smooth, and free of rocks
which may cause point loading on the duct, Where this criteria cannot be accomplished,
the trench bottom should be overexcavated to allow a minimum of 4 Inches of bedding
material under the duct,
Trench width should not be greater than necessary to provide adequate room for joining
the duct in the trench and compacting the backfill in the bedding zone and at the sides
of the duct. The minimum distance between the duct wall and the trench is four (4) In-
ches, maximum recommended trench width is twice the diameter of the duct.
Joining the Duct
Because of its relatively low weight per foot, Spunstrand duct can be joined before lower-
ing Into the trench thus minimizing the number of in- trench joints required in the installation.
Lay out the straight sections of duct and standard fittings to be joined. Field joints require
an internal galvanized sheet metal liner (see physical data), mastic sealer and waterproof
tape.
Attach the internal sleeve to one section of duct with sheet metal sits and apply a bead
of Presstite No. 579.6 waterproof mastic around the circumference at the end of the duct.
Slip the adjacent section of duct over the sleeve and press tightly against the mastic and
secure with sheet metal screws, Wrap the entire joint including all screw heads with Nashua
No, 357 waterproof tape.
MASTIC SEALER
Installation
Store and handle the duct so as to prevent damage. Carefully inspect each length before
installation, If long sections are to be assembled alongside the trench then lowered into
position, the duct run should be supported along Its length to avoid strain that may
overstress or buckle the duct or damage the joints. Lay the duct in the trench so that it
bears evenly on the bedding or bottom of the trench throughout Its entire length. Arrows
on the duct clearly mark the direction of air flow. In locations where it is necessary to locate
the top of the duct so that It projects Into the concrete floor slab a minimum thickness
of two and one-half inches of concrete is recommended over the duct.

Spunstrand Underslab Air Duct is readily cut in the field with conventional tools, such as
a saber saw, band saw or circular saw. A metal cutting blade or reinforced abrasive wheel
is preferable. It is recommended that O,S,H,A, approved fine particle dust masks and /or
other protective gear be worn when cutting the duct.
Backfilling
When backfilling and pouring slab, care shall be exercised to avoid shock loads. Uniform
backfilling is required to maintain the duct in a round configuration at all times, Pea - gravel
or dry sand should be used as backfill under, around and over the duct.
The backfill around the duct should be placed in layers on each side of the duct. Take
care to compact the material under the haunches of the duct and bring the backfill up
in roughly even lifts to avoid uneven loading on the duct walls,
Mechanical compaction Is not recommended due to the extreme care required to avoid
damage to-the duct. Water settling of the backfill Is unsatisfactory because flotation of
the duct is the usual result if the operation Is done properly. Hand tamping Is the recom-
mended method. Pea gravel as dumped from a wheelbarrel 1s approximately 85% com-
pacted. With hand tamping or rodding, pea gravel backfill compaction will approach 95 %,
Space parallel duct systems sufficiently far apart to allow compaction equipment to com-
pact the soil between the ducts, Compact the soil between the ducts in the same manner
as recommended for a single duct with particular attention to the compaction around and
under the haunches of the ducts.
It is not recommended that an engineered fill be brought up around ducts because of the
potential for damage from the compaction equipment and the potential for uneven loading
which could result in collapse. Rather, the engineered fill should be completed to the design-
ed elevation, then the desired trench is dug and the duct installed in the recommended
manner.
Where water is encountered within the trench zone, it should be removed by suitable means
and the trench maintained in a reasonably dry condition until the duct has been Installed
and enough backfill placed to prevent any flotation of the duct, The gradation of the backfill
in the duct zone shall be such that the fines from the surrounding soils will not migrate
into the backfill and cause lack of sidewall or foundation support. As an alternate, the use
of filtration fabric can be considered for this purpose. In either case the assistance of a
soils engineer should be sought,
Heavy equipment shall not be allowed to pass over ducts without proper bridging. Where
heavy floor loads are anticipated, the floor slab should be reinforced over the duct area
or a crown of concrete poured over the duct In lieu of the backfill material, Where ducts
parallel a wall or foundation they should be spaced to provide a minimum of 4" for the
material, Where the duct must pass directly under a bearing wall, reinforcement
over the duct may be required.

WET LAY -UP JOINT
INSTRUCTIONS
Thoroughly clean and sand the area to be joined. Using polyester resin and fiberglass
mat and /or woven roving, the joint may be efficiently performed by applying a coat of resin
to the duct ends, then place the mat or woven roving on same and saturate with addi-
tional resin. If desired, the glass can be saturated before applying to the area to be joined.
An aluminum or cloth paint roller or even a paint brush may be used to spread resin even-
ly, making sure to work out the air pockets and leave no dry glass fibers exposed. Addi-
tional layers of mat may be added until sufficient build-up has been achieved. Care should
be taken to catalyze only the amount of resin that can be used during the pot life of the
resin, (half -hour or less). A little experience will quickly determine the proper handling of
the resin.
The rate of curing of fiberglass products is dependent on temperature. At low temperatures,
polyester resins have a longer working life and require longer curing periods; working time
is decreased and curing takes place more rapidly as the temperature Increases. Decreas-
ing the amount of catalyst prolongs working time.
The following table gives approximately pot life at various temperatures and catalyst
proportions:
Amount Ambient Approximate
Amount Resin Catalyst Temperature Pot Life
1 quart 2/3 oz. 50-60 deg. F. 20 min.
1 quart 1/2 oz, 60 -70 deg, F. 20 min.
1 quart 1/3 oz. 70-80 deg. F. 20 min.
1 quart 1/4 oz. 80.90 deg. F. 20 min,
1 quart 1/6 oz. over 90 deg. 20 min. or less
The catalyst should be carefully proportioned to the amount of resin to be used, and
thoroughly mixed to a uniform blend. Duct joints should be allowed to cure at least 24
hours before being used.
If additional lamination is to be made over a cured area, the surface should be broken
by sanding before application,
Clean -Up:
Preferably acetone, or lacquer thinner may be used for cleaning tools and hands. Soap
and hot water may be used, though not as effectively as acetone. Thorough clean up must
be made before resin cures. Care should be exercised to keep catalyst and resin from
contact with skin. A hand cream applied before working with resin and after clean up,
is highly desirable.
KEEP AWAY FROM OPEN FLAME AND USE WITH ADEQUATE VENTILATION.
Peabody Spunstrand, Inc., has no control over the conditions in which these materials
may be handled, stored or applied. Therefore, can offer no guarantee as to stability
or performance.
S
For large diameter ducts (36" and over) movable internal support braces Including lateral
runners are recommended during backfill. They are to be relocated as backfilling Is con•
tinued and removed upon completion.
