IRON WOODS™ SIGHT & SOUND BARRIERS
Iron Woods™ Noise Barriers have been used in numerous DOT, commercial and private applications to help reduce the transmission of noise into residential areas. Plus, they’re beautiful. No one will argue against the natural beauty of wood. In our primarily concrete and steel-based roadway systems, the application of wood is a welcome contrast. Iron Woods™ Noise Barriers utilize a variety of naturally durable hardwoods and contain no toxic chemical treatments that discolor the natural beauty of the wood.
Consider the benefits of Iron Woods™ as some of the many reasons why you should specify Iron Woods Noise Barriers.

The natural beauty of tropical timber is indisputable. Along our concrete and steel rich roadway systems the application of natural timber is a welcome contrast. The Iron Woods System, unlike most other timber based sound barriers, uses a variety of naturally durable, tropical hardwoods that contain no toxic chemical treatments that invariably discolor the wood.
Strength and Durability
The superior structural properties of the naturally durable, tropical hardwoods used in the Iron Woods System reduce the cost of foundations and allow specification of walls up to 50 feet in height. The Iron Woods System does not require treatment with toxic chemicals to protect it from degradation. High resistance to decay and termites as well as a Class A fire rating are intrinsic properties of the Iron Woods System. Our sound barrier panels have a proven service life well in excess of 25 years with minimum maintenance.
Graffiti Removal and Maintenance
Every municipality that has erected a noise abatement wall (concrete, steel, or timber) knows—they make excellent targets for defacement. Because of the incredible hardness and nonporous composition of the materials used in the Iron Woods System, graffiti removal is as simple as a light sandblasting of affected areas. With the exception of this problem, to which any system is a potential victim, the Iron Woods System is virtually maintenance free.
The Iron Woods System guarantees dramatically reduced full life-cycle costs over pressure-treated softwood systems.
Iron Woods have minimum life span that is five times that of pressure-treated softwoods. Consequently, during the full service life of the Iron Woods System, a softwood sound barrier would have to be installed, removed, and disposed of approximately five times.
The durability of treated softwood is directly related to the depth of penetration of the preserving chemicals. There is no way of determining this detail without taking a core sample of each individual piece of treated timber—this is time consuming, expensive, and impractical. Additionally, each time a piece of treated timber is cut, drilled, or nailed there is potential exposure of an unprotected portion of the wood to elements that expedite deterioration; the result of which is—inconsistent levels of durability and increased maintenance.
Iron Woods Systems are naturally protected through and through—cutting, drilling, and nailing manifest no detrimental effects on the material as it ages.
The Iron Woods noise wall system requires no special treatments during pre-fabrication, installation, or service.
Iron Woods Systems are designed for years of dependable, durable service in aesthetic harmony with the surrounding environment.
All Iron Woods Systems are designed with simplicity and ease of installation in mind. With our basic post and panel construction, there are no complex anchors or other components that can be lost or damaged. Solid, tropical hardwood panels made with aluminum or stainless steel fasteners do not require on-site machining of any kind. All hardware is galvanized, is stainless steel or aluminum and conforms to ASTM standards.
The innate beauty of the wood, if left unsealed, and the manner in which it “mellows” to an attractive silver-gray with age allows Iron Woods sound barrier system blend with its surroundings.
A necessary consideration for any noise abatement system is its eventual disposal at the end of its service life-cycle. Growing pressures from the EPA and OSHA have increased the difficulty and cost of disposal of timber treated with toxic preservatives. Landfills are more and more reluctant to accept this material due to the potential risk of ground water contamination; while the alternative to landfills—burning treated timber—also has its own set of negative environmental and financial impacts. This method of disposal requires specialized vapor filtering furnaces.
The question is: If the disposal of treated timber is difficult and expensive now, what problems and costs will be associated with handling and disposal in the future as environmental regulation becomes increasingly strict?
The naturally durable, tropical hardwoods in the Iron Woods System are easily disposed in an environmentally safe manner. They can also be salvaged and recycled into other uses.
