Reduces reverberation time effectively
Avoids disturbing reflections and flutter echoes
Improves speech intelligibility significantly
Effective sound absorber for the ceiling
The elegant ceiling sail is made of highly effective HOFA PureAkust and counteracts unwanted reverberation in your room. By installing it above a sound source, reflections are absorbed at an early stage to prevent uncontrolled propagation in the room.
Stylish acoustic element
With their unobtrusive and discreet appearance, HOFA Ceiling Sails are an uncomplicated alternative to permanent ceiling suspensions and are ideal for complex ceiling profiles and roof slopes.

The HOFA Style-Line
The products in the HOFA Style-Line combine acoustic effectiveness with an unobtrusive appearance. Ceiling sails, wall sails, room and desk dividers are made from the same highly absorptive material and therefore match each other perfectly.
With the products of the HOFA Style-Line, we can also fulfill a wide range of individual design requests (colors, coatings, special sizes, and shapes) upon request.

Frequently asked questions
Are ceiling sails free from harmful substances?
Yes, of course!
HOFA ceiling sails are made from PureAkust and are health-safe, especially compared to acoustic products made from glass or stone wool. They are tested for pollutants, odorless, free from formaldehyde, bacteriostatic, and allergy-friendly.
The material PureAkust also meets the Oeko-Tex Standard 100 (highest product class).
Which fire protection classification do the ceiling sails meet?
HOFA ceiling sails are flame-retardant (B1) in accordance with DIN 4102-1 and EN 13501-1.
Where is the ceiling sail manufactured?
HOFA Ceiling Sails, like all other acoustic modules from HOFA, are manufactured in Germany.
Acoustic effectiveness
Despite its slim material thickness of 40 mm, which gives the ceiling sail a subtle appearance, HOFA PureAkust offers outstanding absorption performance. With the optionally available cable mounting kit, the distance of the sail from the ceiling can be increased, significantly improving absorption at lower frequencies.
The ceiling sail achieves class A absorption (according to EN ISO 11654) in typical use. It provides significantly higher absorption than industry-standard products (up to 55% better compared to melamine foam and up to 70% better compared to egg crate foam of the same thickness).

HOFA Cable Mounting Kit
The optionally available cable mounting kit allows for suspended installation on the ceiling. The specially designed spiral screws make the installation quick and easy.
By increasing the distance from the ceiling, the acoustic effectiveness can be significantly enhanced. The closer positioning of the absorber to the sound source provides better control of reflections. The kit also allows for angled installation on sloped ceilings and in control rooms, it enables redirection of early reflections at the listening point.
The HOFA cable mounting kit includes:
- 4 ceiling mounts
- 4 metal cables, each 100 cm in length
- Composite screws with locking for continuous suspension
