THE FELT INNOVATOR

Nevima
IVI-Absorption wool

The sound absorption and sound insulation of rooms is the focus of attention. To improve the acoustics of a room, the reverberation time is usually shortened. When increasing the sound insulation, a decoupled (IVI) double wall and/or ceiling is often used. In all cases, a sound-absorbing material is an important part of the solution. Nevima supplies the easily processable IVI Absorption, in a polyester and a PET version, for optimal sound absorption. In addition to excellent absorbent properties, processing or use does not release fibers that cause irritation to the respiratory tract, eyes and skin. The PET quality is also made from recycled PET bottles.

Definition

The IVI-Absorption is an ecological filling material for acoustic absorption and thermal insulation. The product is made of 100% polyester or PET fibers, without chemical binders or additives and is fully recyclable. The IVI-Absorption is easily deformable, but also simple and very pleasant to process. It can be quickly cut to size with scissors, a serrated knife or a filament. The material is flame retardant and also has excellent thermal insulation values.

Applications

When a wall or ceiling needs to contribute to improving room absorption and reverberation time, IVI Absorption Polyester  is an ideal solution. This product has, due to its fine fiber structure, high absorption values. This allows this product to be combined with plating from IVI-Acoustics-BASIC and IVI-Acoustics-PRO. The IVI-Absorption Polyester is also excellent to use behind a slatted ceiling. The IVI-Absorption Polyester is supplied in white and black. Black can be used for visible work, making the mounting of firet cloth unnecessary. The IVI-Absorption Polyester can also be used for pipes and ducts above ceilings. In addition to a higher absorption value, good working conditions are also ensured during maintenance.

The IVI-Absorption PET has a coarser fibre structure and is used as cavity absorption. Used as cavity filling, it prevents cavity resonances. In this application, the insulation values are comparable to the IVI Absorption Polyester, but the price-quality ratio is much more favorable. The IVI-Absorption PET delivers an excellent result in combination with the IVI-Metal system and the IVI-Nail rule. The standard sheet size of 550 x 1,200 mm fits exactly in the IVI-Metal system (style size 600 mm) and between the IVI-Nail rule (size between the lines 550 mm). This size prevents cutting loss.

Advantages

• High absorption values in the speech area

• Fibre-free

• Ecological

• Pleasant and quick to process

Absorption values

The sound absorption measurement in the reverberation chamber of the IVI-Absorption Polyester SG15 yielded NRC (ASTM-C423) values of 0.75. Measurements were taken in accordance with ISO 354:2003 (Peutz report no. A 1870-1).
