Texaa Aeria acoustic fabric
Description
Aeria is the knitted fabric Texaa makes for all of its own products, and it is also sold by the roll. It is sound-transparent: on its own it absorbs very little, because its job is to let sound through to the absorber behind it. It comes as dense Maille Ronde (MR) and open-stitch Grande Maille Ronde (GMR). Use Aeria to cover absorbers and technical installations, not as an absorber by itself. The knit is elastic and follows pronounced edges and curves when stretched. Vibrasto and both Velio products are faced with it, and it can run next to Vibrasto where a surface should stay open.
