The monodeck 30T system is designed to reduce transmission through timber floors in situations where finished floor height is not critical.

Monodeck 30T consists of a layer of 8mm reconstituted ACF (Acoustic Chip Foam) bonded to 22mm V313 P5 moisture resistant chipboard.

When installed as part of a complete sound reduction system, it enables a timber floor to meet the sound transmission regulations of Approved Document E 2003 and subsequent amendments in 2004, 2010 and 2013.

Applications

To be used over existing floorboards for conversions, refurbishments or new build with a new resilient bar ceiling.

Product data

Specification

The acoustic floor shall be:

Monodeck 30T, manufactured by Isomass Ltd. Unit 11, Avenue Business Park, Off Brockley Road, Elsworth, Cambridgeshire, CB23 4EY and installed in accordance with manufacturer’s instructions / recommendations.

Installation

Apply Isocheck Acoustic Angled Flanking Band on the edges of the Isocheck boards just before they are pushed against the perimeter walls to isolate the board from the wall.

Lay monodeck 30T over a structural timber sub-floor, in brick bond pattern, applying Isocheck adhesive to all tongued and grooved panel joints.

Install skirting and trim off excess Flanking Band.

• Monodeck 30T system on existing timber floor (subject to condition) or a new 22mm chipboard deck.
• 200mm x 50mm timber joists @ max. 450mm centres.
• 100mm 45Kg/m³ insulation between joists.
• 20kg/m² boarded ceiling on resilient bars @400mm centres perpendicular to joist direction.
• Acoustic flanking band reduces impact vibration leaking via structural walls and assists in reducing airborne sound paths (on both constructions).
