1 Physically reticulated polyethylene thickness 10 mm nominal self-adhesive overlapping selvage Elastoplastomeric mass Laying side TECHNICAL CHARACTERISTICS Acustic System 10, is a two-layer footfall noise insulation coating with adhesive selvage, made up of 8 mm closed cell physically reticulated polyethylene and elastoplastomeric SBS type material (-15 C) weighing 3 kg/m 2. STANDARD FORMATS 1000X7000X10 mm Mantle thickness 10 mm nominal 12 rolls for pallet m 2 84 per pallet TECHNICAL INFORMATION Self adhesive overlapping selvage 8 mm reticulated polyethylene, density 30kg/m 3 elastoplastomeric SBS type material (-15 C) weighing 3 kg/m 2. DETERMINATION OF DYNAMIC RIGIDITY ACCORDING TO UNI EN STANDARDS. Test report dated (PGM) (see certificate 12A) Apparent dynamic rigidity: MN/m 3 =55 COMPRESSIBILITY TEST ACCORDING TO UNI EN DETERMINATION OF THICK- NESS FOR FLOATING FLOOR INSULATING PRODUCTS. (see certificate 12B) Load applied to screed Compressibility Compressibility level 5.0 KPa 0.2 mm CP2 72

2 FOOTFALL NOISE INSULATION TEST ON ACUSTIC SYSTEM 10 SPECIMENS IN ACCORDANCE WITH UNI EN ISO A footfall noise insulation test was performed on ACUSTIC SYSTEM 10 specimens in accordance with UNI EN ISO 140-7, using a Bausta type floor and a levelling screed of about 7 cm. The indexes of footfall noise normalized levels were assessed for the tested product in three different experimental conditions corresponding to three different floating screed thicknesses. The improvement in footfall sound insulation performance is given as the difference between the results of tests performed on experimental screeds and the result obtained by placing a tapping machine directly on the bare floor L n,w=l n,0,w-l n,w. The whole system, made up of resilient footfall noise deadening material and floating screed, is considered by UNI EN ISO (see par ) standards as equivalent to a floor covering assembly (see certificate 12C) Test result for the 4 cm thick screed: L n,w56db Test result for the 6 cm thick screed: L n,w56db Test result for the 8 cm thick screed: L n,w56db The improvement in product performance is obtained by calculating the difference: L n,w=l n,0,w-l n,w Test result for the bare floor: L n,0,w86db Test result for the 4 cm thick screed: L n,w30db Test result for the 6 cm thick screed: L n,w30db Test result for the 8 cm thick screed: L n,w30db 73

3 RESULTS OF TESTS CARRIED OUT AT THE BUILDING YARD, DATED (see certificate 12D) Test sample description: 1 plasterboard tiles. 2 wrapped rockwool. 3 bent tile floor with air pocket of approximately 30 cm and reinforced concrete core of 7 cm. 4 5 cm concrete cover. 5 ISORUBBER 1 cm. 6 ACUSTIC SYSTEM 10 thermal insulation layer - 1 cm 7 8 cm sand and cement cover. 8 tile finish. Test result: Assessment index according to UNI EN ISO standards R,w=60dB L nw=48db CONTRACT SPECIFICATIONS Floor footfall noise insulation and the separation between screed and perimeter walls will be achieved as follows: Dry laying of ACUSTIC SYSTEM 10, a two-layer coating made up of 4 mm closed cell physically reticulated polyethylene and elastoplastomeric SBS -15 C type material weighing 3 kg/m 2, complete with overlapping selvage to prevent acoustic bridges. Sealing of perimeter walls with ACUSTIC BAND a self-adhesive band in modified expanded polyethylene, turned up past the skirting board level. 74
