Client:
V Festival
Question:
PA scrim or gauze?
Conventional
gauzes were made from cotton. The traditional terminology was 80%
gauze - thus whilst providing some protection and masking for the
equipment, and additionally a base media for artwork, the predominant
function was to allow sound passage through the media with minimal
degradation or diffraction.
The
pitfalls were numerous.
1.
When wet (through inclement weather), the gauze would absorb the
moisture causing the gauze to slub/sag under it's increasing weight
and the flame retardancy (which is non durable) is compromised.
2.
When paint is applied to the gauze, the air gaps become clogged,
thus affecting the acoustic transparency.
3. The overall resilience of the cloth is poor, became misshapen
through stretching or shrinkage.
With
the above criteria the V Festival requirements were as follows.
- Perfect
reproduction of the client's requirements, from high resolution
artwork, to large format gauzes, with no clogging of the airgaps.
-
Keder to the vertical sides to maintain tension when fitted.
-
Water repellent and water proof to maintain shape and flame retardancy
and afford maximum protection to equipment behind.
-
A robust and resilient fabric that can be demounted and reinstalled
in following years.
-
Maximum acoustic transparency with maximum available media to
apply the artwork.
Hi-fli
and Acre Jean worked together to achieve the criteria and give the
best result for the festival.
