Climliner Slab Cleantec Glass Wool Slab : For Internal Insulation of Metal Ducts − Isover

Beyond silence

CLIMLINER Slab CLEANTEC solution provides robust thermal and acoustic insulation to metal air ducts, being installed on the inside face of the metal duct. This solution is used when both thermal and acoustic insulation is required simultaneously, and the CLEANTEC slabs will be complementary to the metal air duct; the insulation will be installed either on the total length of the ventilation system or in some parts of the duct network, either in new buildings or renovation. System can easily be cleaned by brushing or other methods even over 20000 times.

CLIMLINER Slab CLEANTEC system can also be used inside ventilation units or for plenum boxes and for acoustic silencers.

CLIMLINER Slab CLEANTEC system is composed of CLEANTEC Slabs: glass wool slabs faced with durable glass fabric. This fabric will be installed in contact with the airstream, providing:

High acoustic absorption: The inside facing ensures a high acoustic absorption
The inside facing constitutes a smooth surface, with high resistance to tearing (cleanable by brushing)
No fibers in airstream

CLIMLINER Slab CLEANTEC profiles, to be installed on the internal joints of the metal duct to provide a mechanical fixation of the insulation to the duct (see installation details, available on demand).

CLIMLINER CLEANTEC Slabs are manufactured from inorganic and chemically biosoluble materials and do not include anything that would have effect on corrosion.

Acoustic insulation

The glass fabric, combined with the glass wool, provides optimum levels for noise reduction through the duct. High acoustic absorption by the glass wool allows noise reduction of the noise generated in the air fan; but also noise reduction due to the air movement inside the duct.
The alfa Sabine coefficient α of the CLEANTEC slabs allow calculation of the sound attenuation inside a duct: Sabine equation provides an approximation of the linear noise reduction inside the duct:

Reduction in dB/m = 1,05 α × 1,4 (P/S)

Being P the perimeter of the inside duct cross section 2 (a+b) and S the section of airflow inside the duct (a x b)
Sabine coefficients for CLEANTEC slabs are shown in below table:
