What do you suggest/use to attach blankets to a wall?
The are several options:
1) ideally the acoustic blankets supposed to be hanging 6 - 12cm away from the wall to allow for air gap.
2) we have a special screw hooks that were designed to keep the blankets away from the wall.
Here is the hook - VG2GO Hook screw from stainless steel
3) Another option is to first attach to the wall a wooden beam of dimensions approx. 5 x 10 cm (or similar size) which is fixed to the wall at 3 points and then to attach the acoustic blankets (acoustic curtains) use ordinary wood screws, with the use of a wooden board fixed behind the wall you will save time and destroy less of the wall because the acoustic blankets need to be hung at a width of 200cm on up to 8 screws.
4) if you do not want to drill holes in the wall and install wooden studs or VB2GO hook screes, we have a universal stands that can support the acoustic blankets independently. Universal stand would also allow you to separate the room, create a treated section or if you get two or three you can create a make-shift portable vocal booth. Here is the Universal Stand – Flex Tee Stand for Acoustic Blankets
