NB 12 Panel System - Armtec

NB 12 Panel System
Description
Durisol is the proprietary name of a hard, durable,
relatively lightweight and cementious composition.
It is made of chemically neutralized and mineralized
organic softwood shavings which are specially
processed to an acoustically engineered size and
are bonded together under pressure with Portland
cement.
The resultant material is sound-absorbent, non-
combustible, vermin proof, and does not rot. Durisol
is self-draining and highly resistant to weather
exposure including: freeze-thaw, road de-icing
chemicals and fungicides.
Panel Construction
Durisol panels shall be of composite construction, with sound absorptive Durisol fascia incorporated
onto a reinforced concrete core, and having the dimensions and specifications shown on the contract
drawings. The Panel design shall be sealed by a Registered Professional Engineer.
Acoustical Characteristics
Durisol panels shall be sound-absorptive Durisol. The Noise Reduction Coefficient (NRC) shall be greater
than or equal to 0.70 as determined in accordance with ASTM C423 ‘Test Method for Sound Absorption
and Sound Absorption Coefficient by the Reverberation Room Method’. The Sound Transmission Class
(STC) of the Durisol Panels shall be equal to or greater than 32 as determined in accordance with ASTM
E90. Aesthetics: Durisol panel face colours and textures shall be as specified in the Contract Documents.
(Owner to specify colours, percentages of each colour, colour pattern, flat surface both sides, textured
surface one side with flat surface other side and percentages of textured panels).
Steel Posts
Steel posts are manufactured from hot rolled wide flange structural sections in accordance with shapes,
sizes, details and method of connection as shown on the drawings. All structural steel work is compliant
with CSA Standard S16, grade G40.21-M 350W. All welds conform to CSA Standard W59.1 and CSA
Standard 47.1. All steel components are hot dip galvanized after fabrication in accordance with CSA
Standard G164-M. All post designs are sealed by a Registered Professional Engineer.

The NB12 is a post and precast panel
noise barrier system with posts typically
located on 12ft (3.65m) centres. The
NB12 system can be engineered for wall
heights up to 20ft (6m) or more. Panels
are a standard 12ft (3.65m) long by 20in
(0.5m) high.
The NB12 system is flexible in many ways.
It is ideal for slope conditions, directional
changes, and difficult site access situations.
Precast panels can easily be modified for
short bays on site.
All Durisol noise barrier systems are
engineered in house and specify the
material for posts and the depth and
diameter of footings. Standard steel
posts or optional concrete posts can be
accommodated.
The standard NB12 system is noise absorptive
on both sides. It can also incorporate solid
noise reflective or transparent elements, as
well as integrated traffic barriers and retaining
wall panels.
