A telemarketing firm on the 3rd floor of an office building near the Perth CBD had a teleconference room it struggled to use. Noise from the nearby freeway was coming straight through the windows.
The problem
Constant road-traffic noise from the freeway was interrupting calls and meetings in the teleconference room. In a business that runs on the phone, that was costing time and quality.
What we did
- Retrofitted a secondary glazed panel to the inside of the existing commercial windows, using Whisper Glass.
- Added a perforated silica bead tray between the existing window and the new panel to absorb any moisture, so the cavity stays clear.
Secondary glazing works by creating an air gap between the original window and the new panel. The bigger the gap we can achieve, the more road noise it stops, and the existing windows stay in place.
The result
The teleconference room can now be used without the freeway noise interrupting calls.
Tip from Nigel: for road noise, the window is almost always the weak point. Secondary glazing fixes it without replacing the building’s windows.
