ENGINEERED ROOFING ANDWATERPROOFING SYSTEMS

Innovation. Performance. Partnership.

For more than 35 years, Siplast has been a leader

in the development and manufacture of the

world’s most advanced roofing and waterproofing

systems. A member of the Icopal Group, one of

the world’s largest commercial roofing manufac-

turers, Siplast has a history of innovation. In the

late 1960s, Siplast Research and Development,

working in conjunction with Shell Chemical of

Europe, developed SBS (styrene-butadiene-

styrene) modified bitumens. We found that by

properly modifying asphalt with SBS, we could

produce a highly durable elastomeric blend with

exceptional elongation/recovery properties over a

wide range of temperatures.

There are Siplast roofs applied in the early years

of our SBS blend that are still in service today.

Since then, Siplast Engineered Roof Systems

have been applied over all types of deck con-

structions, in the extremely varied weather con-

ditions of more than 40 countries. Over the

years, Siplast SBS-modified bitumen roofs have

changed the least, lasted longer, and performed

better than anyone else’s.

Innovation and product performance are critical.

But the advantages of partnering with Siplast

are equally important to building owners who

can’t afford to have their facilities compromised

by a substandard roof.

Quality Application

Siplast Roofing, Waterproofing, and Lightweight

Insulating Concrete Systems are installed exclu-

sively by Siplast Select Contractors. These inde-

pendent professionals have met the qualifica-

tions of the toughest contractor certification

program in the industry – ours. Their proven skill

and dedication have demonstrated time and

again that they regard themselves as members

of a team dedicated to installing great roofs for

building owner customers.

Complete Roofing and

Waterproofing Solutions

Siplast offers complete roofing and waterproofing

solutions that include all of the accessory compo-

nents necessary to build a great system. Whether

it’s edge metal, roofing fasteners, or sealant, you

can be assured that Siplast accessories have

been designed and manufactured to work with

Siplast SBS-modified bitumen membranes.

Siplast is the only commercial manufacturer to

offer a roof system package that combines SBS-

modified bitumen membranes with the added

benefits of lightweight insulating concrete.

Siplast’s SBS-modified bitumen roof membranes

have a long performance history over lightweight

insulating concrete. Our experience has shown

that the insulation’s encapsulated design pro-

vides a stable, monolithic surface for the roof

membrane system. It has also demonstrated

that the relatively high density of Siplast Light-

weight Insulating Concrete can positively affect

membrane life by impeding extreme temperature

fluctuations and the resulting thermal stresses

that can cause membrane fatigue.

Used together, Siplast SBS-modified bitumen roof

membranes and Siplast Lightweight Insulating

Concrete Systems result in a longer lasting roof.

And, since Siplast Lightweight Insulating Concrete

Systems are reroofable, significant cost savings

over the life of the building can be realized.

Siplast Roof Membrane Products

Every project is unique. That’s why Siplast offers

three families of engineered SBS-modified bitu-

men roof membrane systems with varying com-

binations of blend thickness, carriers, and sur-

facings. This wide variety enables you to select

the Siplast Roof System that perfectly matches

your requirements.

Following is a brief overview of Siplast Roof

Membrane Products. For more detailed informa-

tion, please ask your Siplast Representative for

a copy of the Siplast Technical Guide or Engi-

neered Roof Systems Binder. Commercial Prod-

uct Data Sheets and MSDS for all Siplast prod-

ucts are available on the Siplast Web site at

www.siplast.com.

The Paradiene 20/30 System

Paradiene 20/30 is a proven, lightweight, multi-ply,

highly flexible membrane designed to retain its

elasticity through severe solar load, ultraviolet rays,

thermal shocks, random ponding water, and

extreme low temperature. Both Paradiene’s top

and base plies consist of an elastomeric asphalt

blend – a unique formulation of SBS and high

quality proprietary asphalt – reinforced with a fiber-

glass mat. The workhorse Paradiene 20 base ply

absorbs roof stresses while the granule-surfaced

top ply, Paradiene 30, shields the base from the

elements and mechanical abuse. The granule sur-

face means the system doesn’t require the appli-

cation of gravel, giving it a light installed weight of

approximately 200 pounds per square, and mak-

ing inspection and repair easier.

The Paradiene 20/30 System can be installed

with PA-311 Adhesive or Type IV asphalt. Para-

diene 20/30 TG Series products and Paradiene

20 TS are available for torch applications. Para-

diene 20 SA and Paradiene 20 TS SA are avail-

able for applications requiring a self-adhesive

base sheet.3

The Paradiene 20/30 FR System,

applied with PA-311 Adhesive

over Siplast Lightweight Insulat-

ing Concrete, was chosen for

this Louisiana library.

The Veral System

A tough, lightweight, long-lasting membrane, Veral

combines the proven waterproofing characteristics

of SBS-modified asphalt and the stability and

strength of glass mat/glass scrim with the protec-

tion and dramatic appearance of metal foil. The

Veral System is composed of two sheet compo-

nents, Irex and Veral. Irex is the base ply, consisting

of a quality high-melt asphalt with a fiberglass rein-

forcement. The finish ply, Veral, combines a glass

scrim-reinforced SBS-modified asphalt base with a

protective foil facing. Metal and asphaltic materials

expand at different rates, so we have engineered

special features into Veral’s design. Using a

patented embossing system, small control chan-

nels are built into the metal facing. A thin layer of

low-melt asphalt is factory applied beneath these

channels, allowing the metal to expand and con-

tract independently of the modified asphalt base.

The Veral System is preferably applied by torch-

ing, which utilizes the closely controlled high

melt asphalt in the sheets. The finished assem-

bly provides a strong, flexible, glass-reinforced

membrane, completely shielded from the ele-

ments. Veral is available in energy efficient alu-

minum or Polar White Spectra, rich copper, and

chemical resistant stainless steel.

Parafor 50 LT and Parafor 50 TG

Designed especially for sloped roofs, Siplast

Parafor 50 LT is a single-ply roof membrane com-

prised of a base material that is a blend of elas-

tomers and high-quality asphalt, and a fiberglass-

reinforced polyester mat. The result is a tough,

flexible sheet with the stability and strength of

fiberglass and the puncture resistance of poly-

ester. Parafor 50 LT is surfaced with mineral gran-

ules, and can be applied using PA-311 Adhesive,

a torch, or Type IV asphalt. Parafor 50 TG has a

patented micro-grooved torching surface. The

micro-grooves provide additional surface area

and air channels beneath the film that allow more

rapid torch application than is possible with

Parafor 50 LT. Parafor 50 TG is surfaced with

mineral granules. Parafor 50 LT and Parafor 50

TG can be used as alternatives to Veral for base

flashing applications.

Paraguard Perimeter Edge & Coping

Specifically engineered for use with Siplast Roof

Systems, the multi-component Paraguard System

is designed to be easy to install. The roof edge

features a galvanized steel waterdam/cant that

can be installed at the start of a Siplast membrane

application, allowing phased construction of the

roof system. The fascia component is installed

after the roofing is completed, to ensure a contin-

uous watertight installation. Paraguard Coping

has a galvanized steel anchor cleat plate with pre-

punched nailing holes and a specially designed

guttered splice plate for smoother finish lines.

Paraguard is available in 28 standard factory-

applied finish colors in pre-finished .050 aluminum

and 24-gauge galvanized steel. Custom colors

can be matched individually.

The Parapro 123 Flashing System

The liquid-applied Parapro 123 Flashing System

is the optimum solution for situations where con-

ventional flashing methods would be labor-inten-

sive and cost-prohibitive to install, or application

would be difficult due to accessibility. The Para-

pro 123 Flashing System is a layered application

that encapsulates a polyester fleece reinforce-

ment within two layers of catalyzed polymethyl

methacrylate (PMMA) resin, creating a finished

application that is seamless, fully reinforced,

resilient, and exceptionally durable. Parapro

adheres to Siplast Roof Systems, as well as to

most standard construction materials. Optionally,

Parapro can be surfaced with mineral granules

or a liquid-applied color finish to meet a wide

range of aesthetic requirements.

Paraslope

An asphalt-encapsulated compressible aggre-

gate, Paraslope is used to improve water

drainage on new and existing roofs. Because of

its unique waterless composition, Paraslope can

be layered between roof membranes without

compromising the waterproofing system, allow-

ing the repair of ponding areas where the mem-

brane is already in place. Paraslope can also be

used to fill depressions, to correct slope-to-

drain, and to build up small water diversions.

The Paradiene 20 TG/30 FR TG

System was chosen for this New

Jersey office. The roof was fin-

ished with a Paraguard Roof

Perimeter System.

ZIC, NVS, Insulcel, and Zonocel

Siplast Lightweight Insulating Concrete Systems

combine the unique properties of lightweight

insulating concrete and Insulperm premium

expanded polystyrene foam insulation board.

The lightweight insulating concrete is available in

four mix designs: ZIC, NVS, Insulcel, and Zono-

cel. The four designs represent a range of com-

pressive and tensile strengths, allowing a choice

of system based on substrate and specific proj-

ect circumstances. Each design encapsulates

the insulation board in insulating concrete. This

process provides fire protection, prevents air

infiltration, and bonds the total insulation system

to the substrate.

Insulperm insulation board can be installed in

thicknesses necessary for high insulation values.

The insulation board can also be installed in

stair-step fashion to form a slope-to-drain con-

tour. The finished surface of insulating concrete

allows a nailed attachment for the roof mem-

brane, providing superior wind resistance to the

completed assembly.

Siplast Lightweight Insulating Concrete Systems

provide high performance solutions to industry

concerns such as slope-to-drain, moisture resist-

ance, high compressive strength, dimensional

stability, and the ability to mechanically fasten the

roofing membrane to the insulation. The systems

offer solutions to regulatory concerns including

fire and wind resistance, code approvals, stable

R-values, and environmental safety. Finally,

Siplast Lightweight Insulating Concrete Systems

provide solutions to building owners’ require-

ments – they are economical, reroofable, fully

guaranteed, and proven by a successful perform-

ance history of over seventy years.

Siplast Waterproofing Products

Teranap Plaza Deck

and Green Roofing Systems

Plaza decks and green roofs add a great deal of

aesthetic appeal, utility, and environmental

friendliness to a building project, but they also

create significant waterproofing challenges. For

over 30 years, Teranap has met the needs of

these demanding applications. The torch-

applied, two-ply Teranap System is based on

our proven roof membrane design. The elas-

tomeric base ply, Terabase, is engineered to

retain its elasticity through the rigors of deck

movement. The top ply, Teranap, consists of a

nonwoven polyester mat impregnated and

coated with SBS-modified bitumen. The surface

of the sheet is protected by a root- and punc-

ture-resistant polyester film. Rolls of Teranap are

2 meters wide and 20 meters long. This cover-

age means a significant reduction in the number

of seams as compared to projects using con-

ventional modified bitumen waterproofing prod-

ucts. With fewer seams, and enhanced flexibil-

ity, elasticity, and puncture resistance, the high

performance Teranap Waterproofing System will

stand up to the intense demands of plaza deck

and green roofing applications for years.

The Teranap Waterproofing System can be

specified with a wide variety of surfacings for

plaza deck applications, including pedestals and

pavers, poured concrete, mortar and pavers,

and road asphalt. Green roofing applications

can be specified with many landscape options,

including both extensive green and intensive

green assemblies.

The Terapro Waterproofing

and Surfacing System

As exposed structural elements, balconies, ter-

races, and walkways require protection from

weathering, water ingress, and environmental

damage to ensure long-term durability. Since

these areas are highly visible, they have aes-

thetic requirements that must be considered in

addition to performance requirements. The Ter-

apro Waterproofing and Surfacing System was

developed for these applications.

Terapro is a liquid-applied, layered application

consisting of one coat of primer, one or more

waterproofing layers, a wearing layer, a hard-

wearing surfacing, and a pigmented or clear fin-

ish layer. Reinforced systems for use over occu-

pied interior spaces include a polyester fleece

fabric for additional protection. Each of the liq-

uid-applied layers are comprised of a specially

formulated, solvent and VOC-free, catalyzed

polymethyl methacrylate (PMMA) resin. The

completed high mil thickness Terapro applica-

tion is resilient, monolithic, seamless, durable,

and resistant to UV, foot traffic, mechanical

abuse, and many environmental contaminants.

A Teranap Green Roof System is

being installed on this down-

town Houston high-rise.

The PMMA resins formulated for use in the Ter-

apro System are efficient and safe to apply.

Waterproofing applications benefit from the

numerous advantages PMMA resins hold over

other liquid-applied waterproofing systems. But

perhaps the most dramatic advantage PMMA

offers over other liquid-applied, layered systems

comes simply from the nature of PMMA – appli-

cation speed. A Terapro System can be applied

and trafficked within an 8-hour day. By compari-

son, polyurethane and polyester liquid-applied

systems require a cure time of up to three days

before they can withstand traffic without sustain-

ing damage.

Both reinforced and unreinforced Terapro Sys-

tems can be finished with three surfacing

options: Terapro Colored Quartz, Terapro Nat-

ural Quartz, and Terapro Chips. These surfacing

options offer skid resistance, enhanced wearing,

and numerous color choices. For information on

custom color options, contact your local Siplast

Representative.

Terafoundation Below-Grade Waterproofing

Due to the inaccessibility of the finished water-

proofing, decisions regarding the design and

application of below-grade materials can be the

most important in a building’s waterproofing

scheme. Problems with foundation waterproof-

ing can result in significant cost of repair. Ter-

afoundation is the safe, smart solution. Based

on our proven roof membrane design, Terafoun-

dation combines a proprietary elastomeric

asphalt blend and internal fiberglass reinforce-

ment with components specific to below-grade

applications. The resulting self-adhesive mem-

brane is 50% thicker than standard peel-and-

stick below-grade membranes. Terafoundation

details are based on the same conservative,

redundant design philosophy that has proven to

be successful in Siplast Roofing and Water-

proofing Systems.

Terafoundation Below-Grade Waterproofing

offers a solution for treatment of this critical, dif-

ficult waterproofing challenge based on years of

experience.

Toisite Shingles

Toisite Shingles provide design sophistication in

a practical product with a performance history

of over twenty-five years worldwide. Toisite

Shingles are composed of a high performance

proprietary asphalt blend reinforced with two

independent fiberglass mats. They are available

surfaced with rich copper, colorful ceramic gran-

ules, or distinctive slate flakes, and are backed

by cork chips.

The copper Toisite Shingle, available in a tradi-

tional half-round, 3-tab design, signals con-

struction of the highest quality and attention to

detail. Toisite Shingles surfaced with ceramic

granules offer a wide range of color options, and

are available in half-round, square, and oval 3-

tab designs. Slate flakes, available as a surfac-

ing on the oval tab design, can create yet

another architectural style. At 6 mm (1⁄4-inch),

Toisite Shingles are exceptionally thick, which

results in a dramatic shadow line that adds form

to the roof.

Toisite Shingles combine elegant design with

strength in a practical product that is UL Class A

fire-rated and UL wind-rated.

Toisite Copper Shingles, shown here on

a residence in Wisconsin, can provide a

distinctive roof for any building.

Toisite Copper Shingles were

selected for use on this gaming

casino and convention center on

Teranap Geomembrane

Teranap Geomembrane has earned a success-

ful performance record as the high performance

waterproofing solution for irrigation canals,

dams, wastewater storage, fountains, reser-

voirs, and ponds. Because Teranap Geomem-

brane has an NSF Potable Approval, it is also

suitable for use in potable water storage and

hatchery applications.

Teranap’s elastomeric modified bitumen blend

allows Teranap to remain flexible over time, to relax

and quickly conform to substrate contours, and to

withstand settlement changes in the subgrade.

The blend is reinforced by two layers of poly-

ester, making Teranap less susceptible to punc-

tures resulting from most common causes. Ter-

anap’s thick, nonwoven polyester geotextile

reinforcement layer protects against mechanical

punctures and enhances the product’s flexibility.

Teranap is lightly sanded on one side, and has a

polyester film bottom layer that protects the

geomembrane from subgrade effects.

Teranap can be installed quickly and economi-

cally. It can be placed using common equipment.

Its flexibility allows it to tolerate irregularities in the

substrate surface, which greatly reduces prepa-

ration time and costs. Seaming is accomplished

through torch-welding, a simple technique that

virtually eliminates seam leakage, simplifies

repairs, and can be performed in winter months.

Teranap is produced in two thicknesses, allow-

ing a choice of material most suitable for a spe-

cific application. Teranap 331 is 120 mils thick,

and Teranap 431 is 160 mils thick. Both are

manufactured in lengths from 20 to 100 meters,

and custom lengths are available upon request.
