ALFA

ALFA is a flexible open-cell foam panel with flat, egg crate and pyramidal shapes for high sound absorption in anthracite gray. The geometric egg crate or pyramidal shapes increase the development of the surface area and improve the sound absorption value.
ALFA, because of its acoustic characteristics, is widely used in recording studios, shooting ranges, television production, mobile acoustic panel systems, and engine rooms.

ECOFIBER

ECOFIBER is a roll or panel material made from 100% polyester fibers treated appropriately (carded, layered, and thermo-bound), 100% recyclable with high capacity for thermal and sound insulation.
ECOFIBER does not release fibers or dust, has great dimensional stability and high workability.
ECOFIBER is resistant to chemical agents, fungi, bacteria, and micro-organisms.
ECOFIBER consists of hydrophobic fibers and is permeable to vapor, allowing wall perspiration.
ECOFIBER is odorless, does not lose weight and does not release fibers during processing.
ECOFIBER is available in black and white.
SPECIFICATIONS: :
| Reaction to fire | class 1 |
| Melting point | 250°C |
| Average diameter of fibers | 17 Dtex |
| Average length of fibers | 50 mm |
MULTIPHON 35 e 40

MULTIPHON 35 and 40 are sealed freestanding soundproof panels, formed by interposing one or two membranes in flexible PVC, coated with a plastic containing mineral fillers, with two panels soundproofing in different thickness and density to create a synergy between vibrant "spring" and "mass" to achieve higher acoustic performance.
MULTIPHON is widely used in light partitions, in double brick walls and in the restoration of masonry walls and floors.
MULTIPHON is moisture resistant and waterproof, is cut easily, will not rot and does not lose its technical and mechanical characteristics over time.
