boards used as permanent, stay-in-place concrete Formwork for cast-in-place floor and roof
joists are spaced at 24" [610mm] on center and poured monolithically with the slab to form
euad-Deck concrete forming panels are available in several thicknesses / beam-depths to allow varying spans and loads of the one-way concrete
slabs. Each euad-Deck p"nui i, custom-cut to the exact length required and reinforced with two continuous, galvanized steel, Z-shaped furring strips
(22 Gauge [0.gmm thickness]), which provide attachmenl po¡nts for ceiling finishes and serve as secondary shoring/formwork support. Primary
ihoring Ãust be designed anJ erected as per shoring supplier, project engineer, or applicable building codes (see below)'
euad-Deck panels do not provide any permanent structural support. structural support isprovided by the,reinforced concrete joists and slab topping
only, which need to be designed by a licensed engineer in accordance with ACI 318, ACI 301, or other applìcable standards'
Span and Floor Loads for Quad-Deck
Depending on live and dead loads assumed in the structural design, clear spans of up to 33 feet [10m] - measured from the center of the supporting
elements - can be accomplished without modification to standaid Quad-Deck profiles. Live loads exceeding 100 psf (a.B kN/m'z) can be supported
for shorter spans (see next page). Longer spans and/or higher loads may be achieved by: increasing the T-beam height profile with extra foam-blocks
glued to the top of Quad-Deck-panels; h¡gh-strength concÃte, additional reinforci ng steel, stirrups, post tens¡oni ng, and/or camber. contact the Quad-
Deck Technical Department for details. A licensed engineer has to provide the structural design for each building'
Reinforcement
Reinforcing requirements are a function ofthe des¡red span between supporting points and the load imposed on the structure. The size, grade, and
frequency of reinforcing bar should be determined by a licensed engineer for each project. For estimating purposes, Quad-Deck provides span tables
showing suggested reinforcement'

Slab Thickness
Because of the support provided by the reinforced concrete joists every 24 inches (61.0mm), a much thinner slab section is required. slab sections
between 2 and 6 inches (50 and 150mm), depending on live loads and other forces applied to the slab, are commonly used. This design results in
30 to A}%concrete savings in most jobs, and therefore eliminates 30 to 40% of the mass of the floor or roof reducing the need for greater bearing
capacity of walls and/or footings. R i" lzsmm] slab thickness is common for most residential floors and 5" [125mm] slab is recommended for areas
with high point loads such as garage floors.
Construction Details
Typical construction details are available on the euad-Deckwebsite, www.quaddeck.com, and can be downloaded at no charge in PDF or DWG
file formats. Many common design features are shown, including multiple story applications, p¡tched roofs, cantilevers and more.
Shoring & Bracing
euad-Deck panels require only primary shoring for support or, if required, camber. This means that less shoring is generally required, approx¡mately
every 6, [1.gm] on center and perpendicular to euad-Deck Panels. First and last shoring beams must start at maximum 6" [150mm] from panel ends,
lnstaller is responsible for the design and correct ¡nstallation of shoring for Quad-Deck forms in accordance with ACI (American concrete lnstitute)
347.2R ,.Guide for Shoring/Reshoring of concrete Multistory Buildings", chapter 2, Design. lt ¡s recommended that an analysis of the shoring for
each project be carried out by a qualified eng¡neer
(often provided by shoring suppliers), in add¡tion to
the design of the structure.
Shoring Removal
The concrete structure must be able to support
its own we¡ght (dead load) and the loads imposed
during construction (construction load) w¡thout
excessive deflection that will harm the structure.
Preferred Method: Determination of the length
of time required before removal of shoring (or re-
shoring) should be made by the Engineer of Record,
based on the compressive strength of the concrete
and curing conditions. A ready-mixed concrete
supplier can supply high-early-strength concrete for
early removal of shoring. Alternate Method: lf plans
and contract documents conta¡n no specification
for minimum compressive strength of concrete
at the time of formwork and shoring removal, ACI
347, Section 3.7 provides guidelines pertaining to
one-way floor slabs and the removal of shoring. See

Ceiling Finishes
Ceiling finish (GWB or equlv.) can be attached directly to metal Z strips integrated in Quad-Deck panels. A minimum L5 minute thermal barrier is
required over exposed EpS insulation surfaces. Dropped ceilings can be installed over 15 min. thermal barrier for projects requiring more room for
HVAC or other utìlities.
lndependent tests (October 2008 Applied Technical Services) confirm the average ultimate load required to pull the Z strip from the Quad-Deck EPS
at 380 pounds [172kg] per linear foot. With a factor of safety of 3, the allowable load is 127 pounds [57kg] per linear foot. Quad-Deck Z strip furring is
manufactured with 22 ga. [0.8mm] galvanized steel. Consult fastener manufacturer tables for pullout values of specific screw fasteners.
EPS Board Type - ASTM Ci78,{CAN-ULC 5701
euad-Deck is manufactured from Expanded polystyrene (EPS) at an average density of 1.25 lbs/cu. Ft. [20 kg/m3]. The EPS material corresponds to
Type Vilt in the usA (ASTM C578) and Type 1 in Canada (cAN/uLc s701). EPS is treated with a flame-retardant for use in building insulation. ln most
dàsign scenarios, building codes require that exposed foamed plastic insulation be covered with a minimum 15-minute rated thermâl barriet such as
those listed in this table:

¿[1irrir;r;* $
| ._''
BACKGROUND: The 2016 edition of the Roofing Manual of the National Roofing Contractors
Association (NRCA) includes a recommendation for the use of an arbitrary unit R-value of 5.0 for all
thicknesses and configurations of polyiso roof insulation in lieu of current ASTM C-1289 Long-Term
Thermat Resistance (LTTR) values as published bV polViso insulation manufacturers. After reviewing
the NRCA manual and related documents and presentations, the Polyisocyanurate lnsulation
Manufacturers Association (PIMA) has developed this Performance Bulletin to provide additional
information to support and validate the use of PIMA member published LTTR values as the most
reliabte measure of polyiso thermal value for building owners, designers, specifiers, and contractors.
The North American Standard for R-value Measurement of Polyiso Roof lnsulation
The R-value recommendation and underlying data published by NRCA differ from the long-
established Long-TermThermal Resistance (LTTR) data published by PIMA members
for over a decade. Based on years of research and development, ITTR:
. Remains the most reliable and relevant measure of long-term polyiso roof insulation
R-value for the building designer, specifier and roofìng contractor.
. ls supported by years of scientific study conducted by leading research organizations, including Oak
Ridge National Laboratory (ORNL) and the National Research Council of Canada (NRC-CNRC).
. Has been established as a reliable national consensus standard both in the United States
(ASTM C1289) and Canada (CAN/ULC- 5704) and is incorporated within all North American
building codes as f he designated measure of polyiso roof insulation performance.
Third-party Certified for 0ver Ten Years
Foil-faced Polyiso insulation meets the requirements of the stringent NFPA 285 fire tests required to demonstrate
Polyiso roof insulation LTTR values are further supported by PIMAs OualityMarkcM program, a voluntary program
that allows participating polyiso manufacturers to certify LTTR values through an ìndependent third party.
. OualityMark covers over 30 participating plants across North America, and each
facility must submit to an annual verification of LTTR product values.
¡ During verification, an ìndependent third-party representalive visits each manufacturing
facility and randomly selects a minimum of five boards for testing.
. Each selected board is sent to an approved testing laboratory, and the overall verification process is
administered by FM Global, a leading independent construction testing and standards organization.
. The OualityMark program is supported by over 2,000 polyiso insulation samples tested over the
past ten years, and the ultimate evidence of the success of the program is that all participating
manufacturing facilities have maintained continuous certtfication since the program's inception.
ì:.: PIMA
POLY¡SOCYANUNÄf € JNSULATION
MANIiFÃCTURÉRS ÂSSOCIAT¡ON
The results of the 201 5 OualityMark verif ication testing are provided in the following table. Note that the
average thermal performance of these insulation boards not only consistently exceeds PIMA-member
published thermal values but also surpasses NRCAs recommendat¡on by no less than 15 percent.
It should be noted that the LTTR testing conducted under the OualityMark program uses a more severe
conditioning procedure than the standard R-value test used by NRCA as a basis for its recommendatlon.
ln contrast to the NRCAs conditioning of samples for only a few days prior to R-value testing, LTTR test
samples are cut into quarter inch-thin slices to accelerate aging and then re-assembled into the original
product thickness prior to testing. As a result of this additional accelerated aging procedure, LTTR test results
are almost always more conservative that standard R-value test results. Given the difference in NRCAs
recommendation and PIMAs OualityMark program testing results, PIMA suggests that this difference may
be attributed to a smaller test¡ng sample size used by NRCA to support its recommendation and a possible
lack of experimental controls regarding how NRCA insulation samples were procured and selected.
CQNCLUSI0N: Use a Recognized R-value Measure Backed by Third-party Certification
As a leader in the manufacture of energy-efficient roof insulation, PIMA encourages building owners,
designers, speciflers, and contractors to rely on thermal performance information based on recognized
national standards and validated by a recognized third party. ln the case of polyiso roof insulation, the
most widely recognized standard is ASTM C-1289 "Standard Specification for Faced Rigid Cellular
PolyisocyanurateThermal Insulation Board." According to this standard, the appropriate means of measuring
the thermal value of polyiso roof insulation is LITR as currently published by PIMA members.
More information on the third-party certified PIMA OualityMark program, LTTR and this topic can be
found at polyiso.org.
Notes:
, lt should be noted that LTTR values shown in this bulletin apply only to polyiso roofing products using permeable facers. Other
polyiso insulation products, such as polyiso wall insulation use impermeable or gas-tight facers such as aluminum foil and are tested
uncler a different R-value test method which results in higher unit R values, typically R-6 per inch and grealer. As a result, LTTR
testrng and thermal values shown ¡n th¡s bullet¡n should be applied only to standard polyiso roofing products wilh permeable facers
addressed in th¡s bulletin and should not be applied lo poly¡so insulaïion products \/iÌh gas-light facers such as aluminum foil.

Polyiso's R'vqlue
NRCA recommends polyisocyonurcïe insulotion be specified by its desired thickness
Jan. 1,2014
lhis month, U.S' polyisocyanu¡ate insulation manufacture¡s will
I b.gin reporting long-term thermal resistance (LITR) values
based on updated and revised test methods. As a ¡esult, LITR
values will be less than values previously used.
Theory of foom og¡ng
The R-value ofclosed-cell, polyisocyanurate insulation is affected
by the amount of gas in the foam's cells. Because the R-value of
most blowing agents (gases) is greater than that of air, polyisocy-
anurâte insulation's R-value is greatest when there is more blowing
agent and less ai¡ in the foamt cells.
During polyisocyanurate insttlation'.s service life, air diffuses
into the foamt cells and the blowing agent diffuses out or partially
dissolves into the cell's polymer matrix. Each of these Processes oc-
curs at råtes dependent uPon temPerature' pressure and the foam's
polymer rype, gas rype and cell structure. Generall¡ the inward dif-
fusion of air occurs at a much faster rate than the outward diffusion
ofthe captive blowing agent. l)iffusion rates also are affected by the
foam's thickness and rype of facer sheers.
Because of this phenomenon, the R-value of polyisocyanurate
insulation is not constant. Its R-value is highest soon after man-
ufacturing and decreases at a relatively significant rate during the
earliest portion ofits service life. As polyisocyanurâte insulation
ages further, its R-value decreases at a slowe¡ rate until the gas con-
centration in the foam's cells equals the gas concentration in air, at
which point its R-value no longer changes with time.
R-volue testing
The R-value of most insulation products used in the roofing indus-
try is tested using ASTM C518, "standard Test Method for Steady-
State Thermal Tiansmission Properties by Means of the Heat Flow
Meter Apparatus," originally published in 1963'
'\Vhen urethane foam and later polyisocyanurate insulation
boards were introduced to the U.S. roofing industr¡ their R-values
rypically were reported using ASTM C518 testing conducted im-
mediately after manufacturing and before the cell gas had diffused
f¡om the foam's cells and been replaced with air. As a result, R-
vaJues of 7.2 or higher per inch thickness were reported.
Beginning in the 1980s, the Roof Insuiation Committee
of the Thermal Insulation Manufacturers Association's (RIC/
TIMAÐ conditioning procedure (RIC/TIMA 281-1) and later
the Polyisocyanurate Insulation Manufacturers Association's (PIMAÐ
conditioning procedure (PIMA 101) called for preconditioning
foam samples at room conditions (75 F) for 180 days before R-
value testing. This preconditioning was an early attempt at addressing
polyisoryanurate insulationt R-value loss over time. Using RIC/
TIMA 281-1 o¡ PIMA 101 conditioning, R-values of about 6'6
per inch thickness were reported.
In 1987 , based on extensive testing of in-service R-values,
NRCA and the Midwest Roofing Contractors Association issued a
joint technicd bulletin regarding the in-se¡vice R-values ofpolyiso-
cyanurate and poiyurethane insulation. The bulletin recommcnded
using an in-service R-value of 5.6 per inch of foam thickness. This
in-service R-value was intended to account for polyisocyanurate
insulationt R-value losses over time and provides a more realistic
design R-value for polyisocyanu¡ate insulation during a roof sys-
temt entire design life.
tTTR
During the early 1990s, Oak Ridge National Laboratory (ORNL)'
Oak Ridge, Gnn., in cooperation with NRCA, PIMA and The Soci-
ery ofthe Piastics Industry conducted research that led to the devel-
opment of a new methodology for assessing aged R-values for closed-
cell plastic foam insulation. This methodology involves thin slicing
and accelerated aging ofpolyisocyanurate insulation specimens and
testing their R-values using ACTM C5 18-a process called LITR.
In 1995, ASTM International published an IITR test method,
ASTM C1303, "standard Test Method for Estimating the Long-
Term Change in the Thermal Resistance of Unfaced Rigid Closed-
Cell Plastic Foams by Slicing and Scaiing Unde¡ Controlled Lab-
orarory Conditions," based upon this new methodology.
In 1998, the Standards Council of Canada and Unde¡write¡s
Labo¡atories of Canada published CAN/ULC-S770, "Standard
Têst Method for Determination of Long Term Thermal Resistance
of Closed-Cell Thermal Insulation Foams." CAN/ULC-S77O is
based on ORNlls research and ASTM C1303 and provides R-value
data based on a l5-year time-weighted average' corresponding to a
product's R-value Êve years after manufacturing.
Beginning in 2003, U.S. polyisocyanurâte insulation manu-
facturers began reporting LITR values using a third-parry certifica-
tion program, ¡eferred to as PIMAs QualiryMark'* program. This
program used the 2003 edition of CAN/ULC-S770 for IITR
In 2009, CAN/ULC-
770 was updated. ASTM
C1303 also has been updated
several times since its original
publication; the current
edicion is ASTM C1303-12.
In June 2013, PIMA
announced its QualiryMark-
certified LITR program was
being updated to incorporate
using either CAN/ULC-
5770-09 oTASTM C1303'
11 for LITR determination.
The updated test methods are
reported to result in a mo¡e
accurate determination and
reporting of LITR values.
The effective date for this
change was Jan. 1, 2014. The
new minimum LITR values
are slighdy less than those
from2003 through 2013 and
shown in Figure 2. 'lhe slight-
ly increasing LITR values

gram from 2003 through 2Ol3 are shown in Figure 1.

NRCA recommendofions
Although NRCA participated in the ORNL research and contin-
ues to participate in the task group responsible for the LITR test
method, NRCA does not recommend using LITR for roof system
design. The LTTR method for determining and reporting R-values
may be considered appropriate for labo¡atory analysis and research
comparisons; howeve! NRCA does not consider LITR to be appro-
priace for roofsystem design where actual in-service R-values can be
an important aspect of roof system performance.
ASTM C1303 is performed after accelerated aging test speci-
mens under controlled laboratory conditions, indicated as 72 F x
10 F. ASTM Cl303 also de6nes "long term" as Êve years, which is
inrended âs the time-ìÃ/eighted average of a l5-year period. The im-
plication of this time-weighted average approach is actual R-values
may be higher than the LITR value for an initial five-year period,
but R-values also will be less than the LITR value from years five
through 15.
The design service lives for most roof systems is longer than
the five-year time'weighted averâge because 2\'yeat and longer
expected roofsystem service lives and roofsystem guarantees now
are commonplace. AIso, rooftop temperature conditions typically
vary significantly from ASTM C1303's prescribed laboratory con-
ditions. Therefore, NRCA does not view IJITR as being rePresen-
tative ofdesign intentions or actual rooftop conditions.
In 2005, NRCA participated in a limited testing program that
showed a majoriry of polyisocyanu¡ate insulation samples tested
one to four years after manufacturing had actual R-values less than
their LITR values.
ln 2009, NRCA conducted R-value testing of Polyisocyanu-
rate insulation obtained through distributors; samples ranged in
age from four to 13 months. R-values were tested at a75 F mean
reference temperâture as well as 25 E 40 F and I 10 F and found to
be less than their published LITR values.
In 2011, with the publication of The NRCA Roofng Manual:
Membrane Roof Systems-2)l1, NRCA revised its 1987 design R-
value recommendations to account for polyisocyanurate insulation's
R-values at different temperatures.
NRCA recommends designers use the design R-values shown
in Figure 3 for polyisocyanurate insulation based upon the predom-
inant condition for the ciimate where the specific building being
considered is located. One way to evaluate whether the heating or
cooling condition is predominant is by comparing heating degree
day (HDD) values with cooling degree day (CDD) values for a
specific climatic location. HDD and CDD values are provided in
the ASHRAE Fundamentals Handbook.
Figure 3: NRCAs recommended design R-volues
In 2013, Building Science Corp., Somerville, Mass., published
Information Sheet 502, "Unde¡standing the Temperature Depen-
dence of R-values for Polyisocyanurate Roof Insulation," which
replicated NRCAs 2009 testing with similar results.
'Whethe¡ designers use LITR or NRCAs predominant rem-
perature condition-based design R-values, NRCA recommends
designers specif,, polyisocyanurate insulation by its desired
¡þiçþ¡s55-¡6t its R-value or LITR-to avoid possible confusion
during procurement.

forms are used in construction of plain and reinforced
concrete beams, lintels, exterior and interior walls, and
foundation and retaining walls in Type V construction. The
forms may also be used in Types l, ll, lll, or lV construction
when installed in accordance with Section 4.10. The forms
may be used in fire-resistance-rated construction, provided
installation is in accordance with Section 4.9.
3.0 DESCRIPTION
3,1 General: The Quad-Lock lCFs consist of two expanded
polystyrene (EPS) foam plastic panels separated by
injection-molded high-density polyethylene (HDPE) cross-
ties which are inserted into top and bottom edges of the
EPS panels. Quad-Lock lCFs are shipped as components and
are assembled on the jobsite.
The HDPE cross-ties maintain the EPS panels at fixed clear
distances outlined in Section 3.3. Galvanized metal corner
brackets are provided to reinforce corners, T-junctíons and
angles. Galvanized metal tracks are provided for optional
use at the base and top of the walls to provide form
alignment and resist concrete pressure. Metal wire top ties
for optional use connect the panels with metaltracks at the
top of the walls. See Figures 1 and 3 for illustration of the
forms.
Quad-Lock forms are classified as a flat ICF wall system in
accordance with IRC Section R608.3.1.
3.2 Foam Plastic Panels: The EPS panels are 12 in. high,
48 in. long. Quad-Lock Regular Panels are 2-t/4in. rhick'
Ultra Panels are 3-1/8 in. thick and Plus Panels are 4-t/4in.
thick. The Regular Panels have a nominal density of 1.9 pcf.
Ultra and Plus Panels have a nominal density of 1.44 pcf. All
panels have a flame-spread index of 25 or less and a
smoke-developed index of 450 or less when tested in
accordance with ASTM E84, and comply with ASTM C578 as
Type ll (for Ultra and Plus Panels) and Type lX (for Regular
Panels). The EPS panels have pre-formed slots to receive tie
flanges at both top and bottom edges and preformed
interlock knobs to facilitate positioning of panels while
stacki ng.

3.3 Cross-Ties: Quad-Lock HDPE cross-ties each consist of
4 tie flanges and two legs that span across the concrete
cavity. The legs are joined to one another,4 ¡n' apart, to
form a paired assembly. During assembly on-site, cross-ties
are spaced at 12 in. on center along horizontal joints
between panels, embedding half of each tie-flange into
panels below. The panel above receives the upper half of
tie flanges into molded slots at the bottom of the panel'
The face of each tie flange is recessed from the outer face
of EPS panels by 3/8 in. Legs of cross-ties have regular
depressions along their top edge to assist in positioning
horizontal reinforcing bars. Cross-ties are color-coded by
length to assist in choosing the appropriate concrete cavity
size. Tie color tints are black, blue, yellow, green, red, and
brown. When used with Regular and Plus Panels cross-ties
form cavities of 3-3/4 in., 5-3/4 in., 7-3/4 in., 9-314 in.,
1"1"-3/4 in., or 13-3/4 in. When used with Ultra Panels,
cross-ties maintain clear distances of 4 in., 6 in., 8 in.,
10 in., and 12 in. Quad-Lock XT-Extender Ties are available
to increase the standard wall widths by 12 in. and are
tinted orange.

lRC, walls must be flashed in accordance with IRC Section
R703.8. When the wall covering is mechanically attached
to structural members, the wall covering must be attached
to the flanges of the cross-ties or FS Strips with fasteners
described in Table 3, having sufficient length to penetrate
through the flange a minimum of 1,/4 in. The fasteners
have an allowable fastener withdrawal and lateral shear
strength as noted in Table 3.
The fastener spacing must be designed to support the
gravity loads of the wall covering and to resist the negative
wind pressures.
The negative wind pressure capacity of the exterior finish
materíal must be the same as that recognized in the
applicable Code for generic materials, or that recognized in
a current evaluation report for proprietary materials and
must not exceed the maximum withdrawal capacity of the
fasteners listed in Table 3.
4.5.2 Below Grade: For below-grade applications, exterior
wall surfaces must be dampproofed or waterproofed in
accordance with IBC Section 1"805 or IRC Section R406, as
applicable. The material must be compatible with the ICF
foam plastic units, and free of solvents, hydrocarbons,
ketones, and esters that will adversely affect the EPS foam
plastic panels. No backfill can be applied against the wall
until the complete floor system is in place, unless the wall
is designed as a freestanding wall that does not rely on the
floor system for structural support.
