COT - Oscurante Teatro
is a fabric with blackout and acoustic properties very similar to those of COS - Oscurante
It has a reason for being due to its inherently flame retardant polyester yarn composition, which makes it more stable over time and gives it fire reaction properties that resist water.
It is therefore more suitable, if not indispensable in comparison to COS - Oscurante
, for outdoor use and in areas with a humid climate.
The strength of the polyester yarn also makes it suitable for Stage maskings
intended for touring and rental.
It is plushy and matte only on the front, the reverse, where the twill-woven
with which it is woven is clearly visible, is therefore much more reflective.
Its use is not recommended, compared to COS - Oscurante
molton, where its characteristics of robustness and stability are not needed, because it has a lower degree of light absorption and it is more expensive.
