Acoustical Systems

DuraSystems is proud to have been involved in a wide variety of acoustical solutions using on our products and systems. Many of the unique systems we have designed for fire, blast or thermal resistance also yield impressive acoustical properties that many engineers have discovered over the years.


DuraSteel is ideal for both interior and exterior acoustical applications, particularly when protection of mechanical equipment is required. Its modular construction can be used as a wall, an enclosure or a barrier. DuraSteel systems are available with additional cladding for greater acoustic mass and performance. DuraSteel can be painted for an aesthetical finish or for corrosion resistance in harsher environments.

DuraDuct is the all-in-one acoustical duct system. One system to address fan breakout noise, mechanical protection of the duct system and fire resistance.

Although the overall installed dimensions of the DuraDuct system are no larger than a standard Sheet Metal and Air Conditioning Contractors` National Association (SMACNA) duct, its mass density is an impressive 4.3 lb/ft2 (21 kg/m2), greater than that of two layers of drywall. Its Transmission Loss (TL) properties would be greater than that of 1/4" plate ductwork. DuraDuct, with a Sound Transmission Class (STC) rating of 35, would be equivalent to enclosing a standard 22 gauge duct assembly with acoustic lagging or 1" thick drywall throughout the entire length of ductwork.

The DuraWall thermal system is built around a steel-faced composite panel with a non-combustible mineral fibre core. Available in 4" and 6" thick panels, it has a Sound Transmission Class (STC) of 30-32 and is easily installed as either an exterior façade or an interior wall.

DuraWall is available in a multitude of colours and finishes. It will meet acoustical requirements equivalent to two bonded layers of gypsum wallboard, but at the same time provide an insulation R-value similar to or greater than that of insulated wood or metal stud wall.

DuraWall panels come in sheets 4` x 20` and can be installed horizontally or vertically. Its simple tongue-and-groove connections make installation literally a snap. The DuraWall design is inherently also a thermal wall, as there are no thermal breaks in the panel.

Absorption Panels

DuraSystems Absorption Panels consist of one backing layer of DuraSteel, 4" insulation, followed by one facing layer of perforated sheet metal. This innovative design translates into an acoustical wall system that can provide a Noise Reduction Coefficient (NRC) of 1.05 as well as a Sound Transmission Class (STC) of 45.

DuraSystems Absorption Panels are unique in the industry. By incorporating DuraSteel as the backing layer of the Absorption Panel, engineers can achieve the same fire resistance benefits that one can expect from DuraSystems` extensive line of passive fire protection systems. Along with excellent acoustical properties, DuraSystems Absorption Panels provide up to 6 hours fire resistance, for that added sense of security.

Promat Promasound Sound Insulation Barriers

DuraSystems` new line of Promat Promasound barriers is an innovative visco-elastic acoustical insulation material. The dense material is excellent for applications requiring high acoustic mass in a thin, flexible form. Promat Promasound is a versatile acoustic solution, available in rolls or shets, optional self-adhesive backing, optional aluminum foil facing and customized finishes.

Why is Passive Fire Protection Important?


A major fire can have a devastating affect on both property and people.  Although active fire protection such as sprinklers put out a fire, the smoke from the fire remains. This smoke can be harmful when not properly mitigated. Ventilation systems offer an effective method for the control of smoke.

Smoke can behave very differently in tall buildings than in low buildings. The predominant factors that cause smoke movement in tall buildings are stack effects, the effect of external wind forces, and forced air movement within the building. Smoke removal and venting practices are complicated by stack effects, which will tend to favour natural air movement vertically through the building as a result of differences in temperature and densities between the inside and outside air. 

Pressurization and smoke exhaust systems are methods of controlling the smoke in the event of a fire.  Life safety systems such as these are required to be fire rated so that service they provide will be continued in the event of a fire.
