Formerly named Crown Sound Deadening Quilt, Crown Acoustic Floor Roll is a resilient, medium density glass mineral wool roll faced on one side with a kraft paper/polythene laminate. The facing has a 75mm overlap along one edge to lap the edge of the adjoining roll.
|
| The mineral wool part of Crown Acoustic Floor Roll is a non-combustible inorganic glass wool, defined as mineral wool in BS 3533 and is manufactured in accordance with BSI Quality Assurance Standard BS EN ISO 9001: 2000. |
| The base glass mineral wool of Crown Acoustic Floor Roll is classified as non-combustible to BS 476: Part 4: 1970 (1984). |
Crown Acoustic Floor Roll meets the specification for a resilient layer in a Type 2 floor construction as recommended in Approved Document E 2003 of the Building Regulations, for separating floors. Used with the appropriate ceiling and floor surface treatments, and a structural deck of the appropriate mass, this system has the potential to provide the impact and airbourne sound insulation requirements of Part E.
Post completion testing is still normally required to demonstrate compliance. The acoustic performance depends on the mass of the concrete, which needs to be at least 300 kg/m2. |
| The mineral wool part of Crown Acoustic Floor Roll is odourless, rot proof, nonhygroscopic, does not sustain vermin and will not encourage the growth of fungi, mould or bacteria. |
