The monodeck 26C system is designed to reduce sound transmission and also reduce impact sound transmission through concrete floors.

Monodeck 26C consists of a layer of 8mm reconstituted ACF (Acoustic Chip Foam) bonded to 18mm P5 V313 moisture resistant chipboard.

When installed as part of a complete party floor construction either system enables a concrete floor to meet the sound transmission standards 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.

Performance (on the construction illustrated)

Complies with New Build Robust Detail descriptive FFT5 within EFC-1, EFC-2 and EFS-1.

Product data

Specification

The acoustic floor shall be:

Monodeck 26C, 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 26C over dry level screed, in brick bond pattern, applying Isocheck adhesive to all tongued and grooved panel joints. A VCL will be required when installing monodeck 26C on new screed.

Install skirting and trim off excess Flanking Band.

Full installation instructions for monodeck 26C are available to download by clicking on the link to the left of this page. Installation instructions must be used in conjunction with this information and/our information contained in the datasheet when laying the monodeck 26C floating floor system.

• Monodeck 26C system.
• ≥300kg/m² cast in-situ concrete or hollow core concrete planks with 80kg/m² sand / cement screed or 40mm proprietary screed. 
  Note: A VCL will be required when installing monodeck 26T on new screed.
• 50 x 75mm timber battens with 10kg/m²gypsum board ceiling supported on resilient bars @ 400mm centres perpendicular to the battens min. 75mm below underside of sub-floor or
• min. 75mm void formed by metal frame suspended ceiling system and ≥10kg/m² gypsum board ceiling.
• Acoustic flanking band reduces impact vibration leaking via structural walls and assists in reducing airborne sound paths (on both constructions).
