SOUNDPROOFING AND THERMAL INSULATION

Need to know:

A high sound absorption capacity of the materials corresponds to a mild sound insulating capacity of the material, given their low specific weight.
Therefore a good sound-absorbing material usually has little soundproofing power and vice versa. The absorption by porosity (i.e. materials with open cells or semi-open cells) is generally high at medium and medium-high frequencies, while a significant damping of low frequency requires the use of high thicknesses of porous material but especially a greater specific weight of the product that can be obtained from the bonding a sound absorbing layer to a loaded mass.

POLYURETHANE FOAM

Is a polymer that has very good sound absorption properties thanks to its open-cell composition. It is easy to use both for filling spaces between one wall and another, and for dampening the sound waves within a room.
If, however, you need to prevent the escape of noise produced inside the room itself (for example from an engine compartment), an insulating product is needed, and therefore it is necessary to increase the specific weight of the polyurethane foam with a sheet (or two) of loaded rubber (mass). To get the most out of insulation, it is necessary to apply the soundproofing product to all surfaces of the room in question, including the ceiling, through precise bonding with another anchor using special fastening systems that prevent the product from detaching due to weight, temperature changes, or the loss of consistency of the product over time.

POLYESTER FIBRE AND GLASS FIBRE

Two new products were recently introduced for the sound insulation of engine rooms "FONOX POLYFIBER” and “FONOX GLASSFIBER”..
The first consists of layers of thermo-bonded polyester that, unlike polyurethane foam, does not “crumble” over time, and therefore remains active and effective for much longer. The second consists of a layer of 100% glass fibre. Both are finished with an aluminium film or a glass fibre fabric and, depending on usage, can be bonded with a sheet of loaded rubber (mass) to optimise the dampening effect.

Isopav 22 with lead or loaded rubber

Composition: A first layer of 3 mm cross-linked polyethylene foam combined to a 0.35 mm thick lead sheet of about 4.2kg/m2, and a third layer of 3mm cross-linked polyethylene foam identical to first layer. The result is a high performance soundproofing product, especially suitable for under-floor and under-carpet laying. The surface is protected by a black knurled film.
Auto-extinguishing in class 2 (standard) or certified in class 1.

Polyethylene density: approx. 30kg/m3
Color: grey - black
Thicknesses: 6mm – On request, a 2mm loaded rubber sheet is applied instead of the lead sheet.
Size: Rolled sheets from 100 x 300 cm
Application: Noise insulation. Suitable for medium and low frequencies.

Isopav 11 with lead or loaded rubber

Composition: A first layer of 6 mm cross-linked polyethylene foam combined to a 2 mm thick loaded rubber sheet of about 4.2kg/m2, and a third layer of open-cell polyurethane foam of variable thickness. The result is a soundproofing and anti-vibration product. The surface is protected by a black knurled film. Auto-extinguishing in class 2 (standard) or, on demand all 3 layers that compose it are used, certified separately in class 1.

Polyurethane density: approx. 30kg/m3
Color: grey – silver
Thicknesses: 23 – 28 – 33 – 38 mm. On request, 2 loaded rubber sheets are applied which increase the soundproofing power.
