All values based on data from Huntsman Chemical Corporation, Styrochem International, NOVA Chemical Corporation and BASF Corporation. Federal Trade Commision Ruling: Use the 75 F R-Value when calculating R-Values for residential construction. Design Considerations:
• DO NOT COMPARE polyisocyanurate conditioned R-Values by RIC-TIMA and PIMA to EPS R-Values by ASTM C-578.
• ASK for a 20 year 100% R-Value Warranty. • Flammability: Like many construction materials, EPS is combustible. It should not be exposed to
flame or other ignition sources. Current model building code requirements should be met for adequate protection or seperation from occupied areas.
• Water Absorption Properties: EPS water absorption is low. Moisture takes the path of least resistance and travels around individual beads rather than through them; the non-interconnecting cell structure prevents capillary absorption.
• Water Vapor Transmission: EPS has low permeability but is not considered a vapor barrier.

LiteDeck Floor/Roof System – Stay-in-Place EPS formwork for Concrete Construction
General: The LiteDeck System consists of interlocking rigid polystyrene foam plastic panels with inserted steel or woodstiffeners, and is a permanent formwork for reinforced concrete joists and slab. The system is an ICF (Insulated Concrete Form) panel for floors and roofs to be used in residential and commercial applications.
1.1 Materials: Base Sections: This profile consists of a wire-cut expanded polystyrene (EPS) foam-plastic panel with provision for load-bearing, concrete structural joists. The sides of the panels have an interlocking configuration. Cut-outs for the metal C-channel stiffeners are made on the bottom face of the base sections. The stiffener cut-outs are spaced 12 inches on center. The panels can be either 24 inches or 48 inches wide by lengths as needed. See Detail Drawings in Section 3 The foam billets used to fabricate the base sections are molded from modified, expandable polystyrene beads that comply with Type 8 EPS classification in accordance with the latest ASTM C578 requirements. The foam plastic has a nominal density of 1.25 lbs. pcf and has a maximum flame-spread rating of 25 and maximum smoke-density rating of 450 when tested in accordance with ASTM E84 in a thickness of 4 inches.
Top Hats: This EPS profile comes molded with 100% recycled EPS. During installation, it is attached to the top of the base sections in order to increase the depth of the load-bearing concrete joist. The top hats come in thicknesses of 2, 4 and 6-inches by 4 foot lengths. The foam plastic has a nominal density of 1.25 lbs. pcf. EPS has a maximum flame-spread rating of 25 and a maximum smoke-density rating of 450 when tested in accordance with ASTM E84 in a thickness of 4 inches. See Detail Drawings Section 3; LD 2.3 Steel C-channel: The channels are formed from 18 gauge (0.0516”) Type G90, galvanized steel in compliance with ASTM A653, Chemically Treated, Dry or lightly oiled. The nominal dimensions of the channels are 1 1/2” flange by 3 1/2” web with 3/8” thick return lip. The channels are inserted into the channel cutouts on the bottom face of the base sections. To maintain the base sections in place, 3 inch self-tapping screws with plastic insulation washers are fastened through the top face of the base section and into the stiffener. See LiteDeck Detail Drawing Section 3; LD 2.1
LiteDeck WRS: LiteDeck WRS or Wood Rib System is developed for use with dimensional lumber in place of what traditionally was a steel rib. LiteDeck WRS has cut outs that will accept 2x6 dimensional lumber. See the specs in the Drawings section of this manual 6.0 for dimensions and details.
1.2 Floor/Roof Formwork Installation
Base Sections are installed over temporary shoring. Top hats are then installed on top of base sections as required by code or design. Reinforcing steel is then installed in the joist and in the top slab. Concrete is then placed on the LiteDeck formwork. Once the concrete reaches the required strength, the temporary shoring is removed from under the LiteDeck form. See Installation Manual in Section 4; Marketing Materials
1.3 Structural Engineering

24 ICF BUILDER
Sloped Concrete RoofsTopping an ICF structure with a concrete roof has a number of advantages. Perhaps the most obvious is disaster resistance. A concrete slab will protect belongs and occupants from hurricanes and tornadoes, and is completely fi reproof. (For more information, see Total Shell, Total Protection on page 28 of this issue.)
Th ey can support an enormous amount of weight, so concrete roofs can be converted into decks, rooftop gardens, or even additional parking space.
And coupled with a foam forming system, such as Lite-Deck, concrete can create a high-performance roofi ng system that “completes the energy envelope.” Just like ICF walls, the combination of foam and concrete in the roof protects interior spaces from outside temperature fl uctuations. Near airports, these “ICF roofs” have proven to dramatically reduce sound infi ltration.
But just because a home has a concrete roof doesn’t mean that it has to be fl at. Th anks to innovative forming systems and improved design software, sloped concrete roofs are easier now than ever before. A few builders, like Mike and Dustin King of Ateg Engineering, are taking on incredibly complex roof designs, with multiple hips, valleys, and ridgelines, and constructing them out of concrete.
Th e Kings have designed and built a number of complex, sloping concrete roofs in North Texas. One was installed on the 15,000 sq. ft. Hoff man residence just east of Dallas in Forney, Texas. It has 15 rooms on three levels, and the roof is unbelievably multi-faceted. King even did the bay window roof.
“Most of it was done the same way we do a typical Lite-Deck installation,” says Dustin King. “When it’s on a slope like that, we take a piece of wood and cut it to match the slope, so the shoring can brace off a surface parallel to the fl oor. We can run a screw through
the top of the bracing, through the wood and into the light-gauge steel stud to make sure that nothing moves.”
He uses adjustable Pro-Shore bracing, with beams running 6 feet on center and posts about every 4 feet.
King uses a regular low-slump concrete for most roofs. “We used a 3-inch-slump mix on that project—it has a 7:12 slope—and it stayed in place no problem. I think the steepest we’ve personally done is a 9:12 pitch, and it worked out just fi ne.
Pat Boeshart, inventor of the Lite-Deck system, points out that placing concrete on a sloped surface is not new. “Th ey’ve been
Foam decking creates a series of beam pockets, which are fi lled with reinforced concrete. Pockets running parallel to the ridgeline are usually cut into the foam on site. Some designers recommend a monolithic slab poured over the top of the beams. Others design the fi nal roof fi nish to be applied over the foam.

doing it since the 1960s on concrete-lined canals and stormwater drainage channels,” he says.
Perhaps the most diffi cult challenge for sloped roofs is the engineering and design work.
“A sloped concrete roof is much more complicated,” King confi rms. “Hips and valleys have to be engineered, and a lot of it is using experience and professional judgment.”
On the Hoff man home, King spec’ed a steel I-beam at the ridge line, with the Lite-Deck running perpendicular to the ridge. “We’ve done a lot of steel ridge beams, but we’ve also done a number of
concrete beams too,” he says.Channels for concrete beams were cut into the foam at all the
hips and valleys. A channel was also cut in the foam halfway between the eaves and the primary ridge line, to tie the other concrete beams together and help support the ridgeline.
One unusual feature of this home is that the roof does not have a monolithic slab poured over the Lite-Deck. Concrete was placed in the beam pockets level with the surface of the foam, but no additional concrete was poured above that.”
“Th ere’s no reason why you couldn’t do the slab,” says King. “In this case, it was just the way it was done.” Th e roof was surfaced with Fossilcrete, which was stamped and colored to resemble shingles. Th e same product was used on the exterior walls, which were carved to resemble ashlar-cut limestone.
Cloyd “Joe” Warnes, a concrete expert and consultingengineer, has more than 40 years of experience with pitched concrete roofs. He built one of the fi rst “all concrete” homes in California in 1966 as part of a study by the U.S. Dept. of Housing and Urban Development (HUD). Warnes points out that if the concrete roof is properly tied into the ICF walls, the entire structure is signifi cantly stronger.
Th at’s precisely what King did with the Hoff man home. “We brought the bars out of the ICF wall several feet and tied them into the roof beams. All of the beam connections have ample connecting steel in them.”
All three major brands of foam decking, Lite-Deck, Insuldeck, and Amdeck, have engineering details available on how to make these connections.
Warnes notes that pitched roofs can be built using a number of other technologies—such as steel joists and plywood—but only foam decking includes the insulation, sound attenuation, and other
Sloping concrete roofs are possible. With modern foam decking systems, even complex roof designs can be created.

features most owners will want.At a presentation he gave at the fall 2006 ACI meeting, he
explained the general design process. First, design the structural supports at the ridgelines and in the valleys. Second, determine how the building eaves will be formed and shored. Next, calculate the planking (or other forming) requirements, shoring and rebar needed.
The actual construction process follows those steps quite closely. After the ridgeline beams are installed, contractors form the eaves, shore them, and then place the forming for the rest of the roof. After that is also shored, the rebar is placed and tied into the walls. Any additional beam pockets are cut into the foam at this time. When everything is in place, the concrete is poured, first in the beam pockets, and then as a slab over the entire structure.
The Hoffman home is built without eaves, but King says there are a number of different ways it can be done. “We’ve done it a
couple of different ways. You can end the concrete at the wall, but run the foam out past the wall as eaves. We’ve also formed the eaves with plywood, shored it real well, and poured it with the rest of the roof. Western Forms has an eave form that we’ve used and had good success.” Another possible method is to frame out the eaves as with traditional construction.
Whatever method of pitched roof construction you choose, King says one key is to work closely with the installer and manufac-turer. “The beams on that job came out of out plant at Amarillo, and were delivered to the jobsite pre-cut,” says King. “We worked closely with Ross Raines [the builder] to ensure it went well.”
With foam decking, interior finishes are installed just like they would be in ICF walls. Chases and light boxes are cut in with a hot knife. Insuldeck has pre-cut utility chases molded into the foam. Sheet rock is attached to the integral furring strips. Sometimes, a dropped ceiling—similar to commercial construction—is installed.

Foam decking can be capped with a solid concrete slab for maximum protection, or finished with just the beam pockets (bottom right.) The decision will affect the amount of bracing required when the foam panels are set in place (bottom left.)
August/September 2008 27
King and Warnes are both enthusiastic about the future of pitched concrete roofing. Warnes claims that with the worldwide availability of foam decking, “the last barrier to practical construction of all concrete houses has now been breached.”
King was introduced to the technology through Pat Boeshart and others at Lite-Deck, and calls it “the greatest thing.” “It really is a great product,” he says. “We’re still developing what you can do with foam.”

Innovation & Design Process (ID): This LEED category covers credits available for innovation and exceptional performance above and beyond the requirements of the program. There are no ID Prerequisites for LEED Certification in this category: Credits are obtained for: ID Credit 1: Substantially exceed LEED requirements ID Credit 2: Apply strategies or measures not covered in LEED ID Credit 3: Use LEED Accredited Professional as part of Project team. Past LEED Certified projects incorporating Lite-Form Technologies have been able to qualify for credits under this category for the following:
No off-gassing: Lite-Form product is inert, does not contribute to any degradation of the interior environment. Long Life Cycle: Concrete structures are very durable and will last far longer than other types of conventional construction. Mold Growth control: The entire Lite-Form assembly from formwork foam, plastic ties and the concrete are all inorganic and will not contribute to promotion of growth of mold. Use of High Percentage of Cement Substitute: Moving beyond the usual modest percentage of fly ash, slag cement, or silica fume.
The durability of the concrete structure created through the use of Lite-Form Technologies and the inert and inorganic features of the forms help the product contribute to LEED credits under this category.
