Nudura™
Description
Nudura™ Forms are based on simple interlocking, stacking,
"blocks" or Form Units of flame-retardant expanded
polystyrene (EPS) panels connected by molded-in high density
polyethylene structural foam bridging. They are lightweight,
easy to cut with a hand-saw. Filled with concrete they
create a monolithic wall with an insulation value of R25
and a three-hour fire rating. 
Reinforcements may by placed where needed to satisfy strength
requirements for above or below grade load bearing walls,
beams, lintels, and shear walls.
The standard form units have external dimensions of 96"
in length and 18" in height with an overall wall
thickness of (11-1/2") which in turn encloses a (6-1/4")
thick concrete wall. Both sides of the unit are of equal
thickness, (2-5/8").
 The
polystyrene side panels have a preformed interlocking
mechanism along their top and bottom edges to facilitate
stacking, providing a solid friction. between courses
and preventing leakage of freshly placed concrete.
The Nudura™ System is proven technology. Similar
units have been used successfully in thousands of projects
throughout Europe for more than 30 years.
Nudura™ has the largest form unit in
the industry which will reduce labour cost by 50% or more.

Ceiling and Floor Technolgies
Applications
Nudura™ Form Units are designed for above and below
grade installations in detached, semi-detached or row
housing units, including multi-storey buildings (subject
to engineering limitations). Nudura™ Form Units can
also be used for other building types such as industrial
malls, commercial and institutional buildings. Nudura™
walls can be finished with stucco, similar exterior coatings,
or siding. Special units are available for masonry in
above grade construction.
Nudura™ walls are also excellent when
used for swimming pool walls - the insulation prevents
heat loss.
Advantages 
Nudura™ provides the least expensive method for constructing
an R-2000 house (R 25).
Nudura™ walls have a 3-hour fire rating
when filled with concrete.
Nudura™ Building System takes less
than half the time of conventional construction.
The completed wall already incorporates and is ready to
finish on the interior and exterior. Electrical outlets
in exterior walls will not cause air infiltration. Uniform
interior temperature means greater comfort and energy
savings.
The high mass of Nudura™ walls minimizes
sound transmission. The STC rating is impressive 50.
No chlorofluorocarbons (CFC's or HCFC's)
are used or produced in manufacturing.
Nudura™ Form Units provide a moist
cure which slows dehydration, creating a significantly
stronger concrete wall.
Features
Accessory units provide for angled corners, corbelling,
lintels, etc.
Nudura's™ patented, structural plastic
webs embedded in the form provide full height, visible,
fastening strips on both interior and exterior faces,
perfect for attaching drywall, paneling or siding using
screws or nails.
Patented bracing/scaffolding guarantees
perfectly aligned and plumb wall construction and provides
a convenient elevated working surface.
Nudura™ Form Units can be cut with
a saw in seconds to suit plan dimensions.
Should reinforcements (rebar) be required,
it is installed in the special indentations in the plastic
web. Lintels can be conventionally reinforced.
Codes, Standards and Testing
Test results and design analysis show that Nudura™
provide the level of performance complying with the National
Building Code, Part 4 and Part 9. (Full technical data
available upon request). NRC File # 9420/03131.
