FANTONI
Fantoni is a family owned business, internationally recognised in the production of office furniture, chipboard and MDF panels. From the self-production of energy to the development of new materials, from ergonomic research to sustainable design, Fantoni keeps its eye on an unchanging goal: people and their health and comfort.
ACOUSTICS
Acoustic quality is a fundamental aspect of the design of a room. It depends primarily on the geometry of the space, the type of materials present within it, their distribution relative to sources of noise, sound reverberation, and total background noise level.
The correct acoustic design of a space is only possible if its destined use is defined beforehand. Indeed, different characteristics are required for a theatre than for a concert hall, for an office than for a classroom, and for a gym than for a restaurant. What they should all have in common, however, is the fact that the sound signals that propagate within them should convey to the listener the full meaning and perfect definition of the message they carry, be it in the form of a piece of music or a verbal communication.
It is not unusual for people to find themselves in rooms where the atmosphere is so thick with noise that it becomes very difficult to hold any kind of conversation with their companions. This condition generally leads everyone to raise the volume of their communications in order to restore an acceptable level of intelligibility, thereby further increasing the overall level of sound pressure in the room, a phenomenon which is destined to escalate ad infinitum.
In order to prevent situations of this kind, the main parameter to be controlled so as to ensure good acoustics is reverberation, the total sound that persists within a space for a certain period of time after the source has stopped emitting the sound. The decline in this ‘tail of sound’ can be quantified as a ‘reverberation time’, which is inversely proportionate to the total acoustic absorption capacity of the room. Thus, the application of sound-absorbent materials makes it possible to reduce and contain this time within an optimal range of values, according to the intended use of the space, and so to guarantee the impression of an acoustically ‘dry’ and well-defined environment, a fundamental condition in ensuring ideal communication levels and optimal acoustic comfort.
LETWOOD
Designed for both walls and ceilings, Letwood is an original concept combining innovative design and top quality acoustics for panels that are unique both visually and acoustically. Letwood provides countless solutions because of its square format, modular system, and interchangeable elements. Panels are available in four different patterns for a wide range of decorative options.
The perfect product for high-end design, acoustic quality and comfortable interior environments: ideal for airport lounges, hotel foyers, public transit areas, bars, clubs and stores.
The Letwood panel can be wall mounted using the same system of profiles and connectors used for Echolinear planks. Each panel is set at a distance of about 2 mm from adjacent panels, thus creating a further sound-absorbent opening. With adhesive-free mounting, this product can be removed and re-used in its entirety without damaging any of the components.
ISLE
Isle is a modular suspended kit system with high sound absorbency, designed to improve the acoustics of any interior, even in situations where architectural constraints make it impossible to work directly on the wall or ceiling. A range of four types of panel, featuring different densities of grooving and rear perforations, offering a variety of possible uses with excellent sound absorbency.
Panels are installed by attachment to stainless steel cables fixed to the ceiling using a selection of easy-to-use hardware. The perimeter frame has a 30 degree pitch to achieve a minimal visual weight and incorporates a concealed recess for optional uplighting. The rear of the panels is covered with a sound-absorbent film in black non-woven fabric and a rockwool insulation blanket completes the kit.
CLOUDAKUSTIK
Why must everything be in straight lines? Sometimes a project dictates a freer approach. Cloudakustik offers a suspended acoustic panel system of organic, cloudform shapes in three different sizes making it possible to create your own sky.
A polyester fibre or Rockwool layer, positioned above the panel, completes the system, ensuring high levels of sound absorption.
Cloudakustik kits come complete with perforated face panel, acoustic backing fabric, polyester acoustic batt, edge profile and 4 x 2m stainless steel suspension cables and end fixings. Site specific fixings by others. Holes can be drilled for lights, sound diffusers and other accessories as required.

LETWOOD
Letwood is installed by assembling E0 wood fibre based panels using a dry click-lock system (without adhesives or resins). Precision milling provides geometrical grooving on the front surface, directly connected with an identical but slightly wider pattern and partially open cavities on the rear surface of the panel. Surface milling is 8mm wide.
The acoustic absorption capacity varies according to rear perforation and milling. Sound absorbency spectrum characteristics also depend on the installation method and materials applied in the rear cavity of the Letwood facing. Sound absorbency coefficients are available for each standard model and installation method.
Panelling is installed using our metal omega profiles (L 24 mm, H 18 mm), on which the square panels are fixed using special moulded metal plates (total cavity depth is 20 mm). Installed panelling, composed of square panels, fixing plates, and omega ‘hat’ profiles, has a total thickness of 36 mm, with a weight/surface ratio of about 12 kg/m².
For ceiling installation, flat or channel metal profiles are attached to the underside of the existing ceiling. The square panels are then fixed to the profiles using concealed fastening attachments. Wood fibre panels can be subject to slight changes in size according to EN317 standards.
