Maximum efficiency

Our Acoustic Curtains ISO 3, ISO 5 and ISO 7 combine sound absorption and sound insulation. Multiple layers of heavy acoustic fabric allow for an efficient absorption of high and mid frequencies. Additionally, sound reflecting foil is used to increase the sound insulation further.
These curtains are great for any situation where rooms need to be divided acoustically and reverberation needs to be reduced, for example in doorways and small offices. We recommend a 1.5 to 1 pleat ratio, so a 150 cm wide curtain covers an area of about 100 cm wide perfectly.

Highest quality

HOFA Acoustic Curtains are made in Germany by HOFA. Excellent manufacturing and high quality materials make our curtains good looking even after years. All curtains have metal eyelets, are seamed and can be used from both sides.

More layers for more sound insulation

By the extension with additional layers the HOFA acoustic curtains provide ISO 5 and ISO 7 in the comparison to the HOFA acoustic curtain ISO 3 for improved sound insulation levels.

The additional layers are the reason for the higher effectiveness. Three heavy, sound absorbing cotton layers are combined with two acoustic foils with a high density. The sound transmission is reduced tremendously.
