DuraSound construction & acoustic performance
Won-Door DuraSound has an STC43 acoustic rating and is ideal for separating and dividing off areas where a sound barrier is required. DuraSound is commonly specified in Classrooms & Meeting Rooms, Conference Centres and many other applications where larger areas are divided into smaller multi-use spaces. DuraSound provides superior acoustic insulation and durability at a very cost effective price.
DuraSound acoustic partitions operate on a patented twin track system. Unlike other pantograph style partitions, DuraSound is engineered with no internal parts to get damaged or fail under operation. Won-Door DuraSound is a double walled aluminium partition with an internal air cavity designed to absorb a tremendous amount of abuse without showing a dent or scratch on the door. This air space between the two aluminium walls creates an effective cushion against even the most severe blows.
Available in heights up to 6m and virtually no limitations for width (for doors over 4m tall Motorization is recommended).

Acoustic Performance
DuraSound has an STC43 rating.
What is STC? Sound Transmission Class (STC) is an integer rating of how well a building partition attenuates airborne sound. Numerical values for STC are comparable to Rw values (Weighted Sound Reduction). As a guideline it is commonly accepted that an Rw33 (or STC33) rating is suitable for primary schools and small meeting rooms. While an Rw38 (or STC38) is appropriate for meeting rooms, church halls and classrooms.
The performance of an acoustic partition also depends on the building in which it is installed. Peripheral leakage can occur through the ceiling, floor or even through air conditioning vents and can limit the effectiveness of an acoustic partition.
