- Is it possible to have a single suspension track flush with the ceiling? - No, the elements need to be turned and space is required between the ceiling and the top of the element to minimize damage from any pendular action of the element, when opening and closing the partition.
- Is it possible to stack the sliding elements outside of the conference room to maximize floor space? - Yes, if a wall plug is designed into the side wall, the door elements can be slide through the wall are parked outside of the room.
- From what structures can a Variflex® acoustic mobile partition be hung? - 1. A concrete structure 2. Steel I-beams 3. Rafters
- Do we manufacture a glass Variflex®? - Yes, this is our latest innovation.
- On a multi-function wall, are fixed posts needed where the walls join at 90 degrees? - A wall connection is added to the main wall for the side wall connection.
- Can a Variflex® partition be suspended from a coffered slab? - Yes, it is possible. Careful consideration should be given to the fixing points.
- Can Variflex® tracks cross each other? - No, they cannot. They can join as a T-junction.

- What are the maximum sizes of a pass door in a Variflex® mobile acoustic partition? - A pass door provides for a people to pass through a Variflex wall without having to open panels of the wall. The pass door sizing will differ according to the element height and width of a Variflex mobile acoustic partition.

- If an element height is greater than a standard board, what jointing can be used? - Various types of board joint can be used. Where boards are joined with veneers or melawoods, there can potentially be pattern or colour variance.
- What type of finishes can we accommodate on a Variflex® mobile acoustic partition? - The surface finishes are highly variable and can include fabrics, upholstery, glass, Melawood, Formica, painted finishes and wall papers.
- What do different dB ratings mean? - Decibels are a measure of sound from 0 to 130 where 0dB is not audible to the human ear and 130dB sound will cause pain to the human ear. So, a 40dB sound reduction means that a sound measured at 100dB will be reduced to a sound measured at 60dB.
- How is success or failure of a Variflex® acoustic partition measured? - Provided the system is operated correctly and all seals are engaged, the system can be acoustically tested to ensure conformance to the specific sound reduction offered by different partition solutions.
