Acoustic Flooring & Wall Treatments

SDG work in partnership with Isomass Ltd. Together we are one of the UK and Ireland’s largest suppliers of acoustic floor, wall and ceiling systems for architectural and domestic projects.

Our domestic acoustic flooring, wall and ceiling solutions are designed to control intrusive noise whether it is airborne sound from speech, televisions or impact noise from footsteps, banging or slamming doors.

Acoustics for Timber Floors

Monodeck 17T, 26T and 30 T systems are designed to reduce transmission through timber floors in situations where finished floor height is not critical.

Monodeck 26T and Monodeck 30T boards consist of a layer of 8mm reconstituted ACF bonded to 18mm or 22mm V313 P5 moisture resistant chipboard; Monodeck 17T boards consist of a layer of 8mm reconstituted ACF (Acoustic Chip Foam) bonded to 9mm moisture resistant medium-density fibreboard.

When installed as part of an Isomass approved separating floor construction either system enables a traditional timber joisted floor to meet the sound transmission standards of Approved Document E 2003 and subsequent amendments in 2004, 2010, 2013 and 2015.

Applications:

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

Benefits:
  • Closed cells prevent water absorption which can impair
  • Simple to install with highly efficient results
  • Reduces impact sound transmission in finished wooden floors
  • Includes a moisture-resistant chipboard
Acoustics for Concrete Floors

Isocheck Cradle acoustic flooring system is designed to reduce impact sound transmission through uneven or cambered concrete floors by elevating the floor on timber battens that are supported by a pre-treated adjustable plastic cradle (Otherwise, can be referred to as an acoustic saddle). This system not only facilitates the incorporation of services but is also frequently specified with water based underfloor heating systems.

Isocheck Cradle consists of a 5mm layer of Isopoli HD foam bonded to an injection moulded plastic cradle. The system includes levelling packers in various thicknesses as well as elevating blocks where a greater degree of height is required beneath the acoustic cradle. When installed as part of a complete party floor construction this system enables a concrete floor to meet the sound transmission standards of Approved Document E 2003 and subsequent amendments in 2004,2010,2013 and 2015.

Applications:

To be used over hollow core, cast in-situ or supported metal deck concrete floors for new build or various types of conversion.

Benefits:
  • Reduces impact sound transmission through concrete floors.
  • Corrects uneven or cambered concrete floors.
Acoustic overlay for Joisted Timber Flooring

Isocheck RENOVO acoustic flooring system is designed to reduce impact sound transmission through traditional joisted timber floors where there is little or no access available to enhance the ceiling below for both sound insulation and additional fire protection.

Isocheck RENOVO consists of 8mm environmentally friendly Ecopoli resilient layer bonded to 18mm p5 moisture resistant chipboard. When installed as part of a complete party floor construction either system enables a traditional timber joisted floor to meet the sound transmission standards of Approved Document E 2003 and subsequent amendments in 2004, 2010, 2013 and 2015.

Applications: To be used directly over existing floorboards in refurbishment, conversion, and listed building projects.
Benefits:
  • Tested by NHBC and UKAS or ANC compliant consultants for use in conversion applications and meets performance requirements as specified in the latest version of approved document E of the building regulations with or without the use of a proprietary resilient bar or MF suspended ceiling system. (further guidance is available on floors with direct fixed ceilings, as some shallower constructions may require a different approach).
  • Ideal for listed buildings – incorporated over the floorboards or chipboard. This method is second fix making it one of the last operations, thus avoiding costly protection which is often necessary on alternative direct to joist systems.
Acoustic Treatments for Walls and Ceilings

Isowave 23 consists of a 10mm Isowave acoustic foam measured to BS EN ISO 845:2009 bonded to 12.5mm high density, square edged fibre-reinforced gypsum board. The system incorporates acoustic foam which is semi rigid and is an excellent absorber with high damping characteristics when bonded to an acoustically reflective stiff surface.

Isowave foam is manufactured using water as a blowing agent and is free of CFCs, HFCs or HCFCs. The acoustic ceiling system complies with requirements of EU Regulation No 2037/2000 for ozone depletion and offers good thermal properties. The Isowave 23 acoustic wall system is for the treatment of excessive flanking sound that bypasses a separating floor via lightweight structural walls.

The Isowave 23 acoustic wall system is used to enhance a wall that is found to underperform or to provide a high performance wall commonly used in home cinemas/studios. Also in situations where commercial activities adjoin a dwelling or for upgrading separating walls where there is limited space.

This is a versatile system used in refurbishments or new build with a decoupled ceiling as illustrated or otherwise approved by Isomass.

Isowave 23 acoustic ceiling system complies with requirements of EU Regulation No 2037/2000 for ozone depletion and offers good thermal properties.

Applications:

To construct or upgrade separating ceilings for conversions, new build and refurbishments projects.

Benefits:

  • Reduces unwanted flanking noise in order to comply with Approved Document E 2003 and subsequent amendments.
  • Fire protection 30 minutes for a single layer
Isolation Strip

Our Isolation Strip is ideal for upgrades when looking to increase impact sound insulation from footfall noise on floors and reduce structure-borne noise from doors closing and light switches on stud walls.

It has no adverse effect on the structural stability of the walls and its adhesive backing ensures it can be held in position as the work progresses.

The Isolating Strips are composed of cross linked Isopoli foam with a self-adhesive layer on one side.

They are designed to enhance impact sound insulation when used within all types of construction by isolating timber, steel and masonry separating and partition walls.

Applications:

Can be used on timber, steel and masonry separating and partition walls.

Benefits:

  • Ideal for upgrades when looking to increase impact sound insulation from foot fall noise on floors and reduce structure-borne noise from doors closing and light switches on stud walls.
  • Has no adverse effect on the structural stability of the walls and its adhesive backing ensures it can be held in position as the work progresses.

CASE STUDIES / St Patrick's Academy, Dungannon

SDG worked with Tracey Bros on bespoke panels for St Patrick's Academy.

As our knowledge of the impact of the correct acoustics in different environments grows it is no surprise that the education sector is one area where you can’t afford to be complacent.
