Noise Control Data
STC32 - Heavy Wall Specific:
STC rating (sound transmission loss) of 32 - bettered only by much more onerous and costly concrete noise wall systems in known (previously tested) materials. STC20 is the minimum requirement for a true sound barrier designation.
"Live wind load" panel performance of 45 psf on 10' post centers. Exceeds requirements for 100 mph at 14' heights in most open terrain (Exposure C).
Surface density of 4.12 lbs/ft2 - exceeding the 4.00 lb/ft2 criteria - without any significant surplus mass (cost).
Typical applications: key arterial roads and highways, commercial
developments,
industrial sites.
STC25 rating - still exceeding mandated minimum but at reduced cost.
Surface density of 2.36 lbs/ft2.
Typical applications: some roadways, housing development perimeter fencing, schoolyards, business yard enclosures.
Benefits With Both Systems:Highly durable. Will not corrode, erode, rust or rot. Material lifespan measured in multiple decades as opposed to years
Near zero-maintenance. No aftercare (painting/staining) required. Rain will wash most accumulated (environmental) residue away. Excessive dirt can be power-washed away if desired. Graffiti can be removed with detergents or solvents.
Easy installs - no heavy equipment required with panel (rail) placement.
Walls can also be
easily configured to house "doorways" & portals for access
to city
services like hydrants.
Various colors and "patterns" are available for contrast or for a more aesthetically pleasing finished structure.
