32mm Isocheck 32T is an acoustic direct to joists flooring system used to reduce sound transmission and improve acoustic and thermal performance where both the floorboards and the ceiling have been removed.

Overlay Acoustic Floor System Isocheck 32T 2400mm x 600mm x 32mm consists of 6mm reconstituted ACF (Acoustic chip foam) and 4mm Isofiba, bonded to 22mm P5 V313 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.

Isocheck 32T can be used over new or existing joists for new build, refurbishments or conversions projects with a new resilient bar ceiling.

During installation of direct to joists floor system Isocheck 32T the floor void between the joists should be swept free of debris.

All nails and screws on top of the joists removed or driven flush to leave a smooth continuous dry surface to receive the system.

The finished Isocheck 32T system should be protected with an appropriate layer immediately after being installed to prevent damage.

32mm Isocheck 32T Direct to Joists Flooring System Installation Guidelines:

 · 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.

 · Board fitting should begin at the furthest point from the entrance and marked out so as not to finish with any panels less than 200mm wide.

 · The decking must be laid in a broken bond pattern, with all joints glued and staggered - no mechanical fixings should be used.

 · Isocheck adhesive is applied to both the top of the tongue and the bottom of the groove on each side of each joint.

 · The Isocheck 32T boards are then pushed tightly together.

 · Surplus adhesive should be wiped away from the surface with a damp cloth.

 · Isocheck 32T must be kept in a dry storage area.

 · Deliveries should be scheduled to coincide with availability of suitable dry storage areas.

 · It is advisable that any new ceiling installation be installed prior to laying of the floor together with a continuous layer of 100mm (45kg/m3) mineral insulation between the joists.

 · Where applicable resilient bars should be installed perpendicular to the joist direction at the manufacturers recommended centres - typically 400mm.

 · Installation of Isocheck 32T should not commence until roof, window glazing and wet trades are completed and the structure is watertight.

 · Leave overnight for adhesive to cure before trafficking the newly installed system.

 · Stud partitioning should be built from the joists which should ideally be isolated as much as possible.

 · If it is your intention to build off the top of Isocheck 32T additional advice should be sought before you start.

 · All partitions built from the sub-floor will require Isocheck flanking strips installed to the partition and additional support on each side of the soleplate where the isocheck is terminated.

 · Isocheck Flanking Strips provide isolation of the flooring system from all vertical structures and penetrations.

 · The Flanking Strip is trapped to the wall and returned down over the Isocheck 32T board as the perimeter boards are placed.

 · The skirting board is then fixed to the wall securing the Flanking Strip between the skirting board and the Isocheck 32T.

 · After the skirting board is installed, simply trim the Flanking Strip flush with a sharp knife.

 · Door openings should have linings fitted prior to the installation of the acoustic floor.

 · The Isocheck 32T boards should be carefully detailed to ensure a good fit.

 · Although not ideal, architraves and stops can be fixed after floor installation, leaving a 2/3mm gap from the surface of the floor.

 · The finished Isocheck 32T system should be protected with an appropriate layer immediately after being in-stalled to prevent damage by any following tradesmen.

 · Some Isocheck boards may be HEAVY - Please observe proper lifting methods and if transporting around site, by hand.

 · Care should also be taken to protect hands from splinters during manual handling.

 · The cutting of boards, either by hand or machine, will produce dust that may be an irritant if inhaled.

 · USE dust masks when carrying out any cutting operations.

 · Appliances and sanitary ware, with rigid plumbing connections that penetrate the system, should be isolated from the sub floor and floating floor.

 · Should be isolated by cutting a hole up to 10mm larger than the service diameter and filling the gap with a flexible sealant.

 · Ideally kitchen worktops should be isolated from the wall with a Isocheck Flanking Strip and trimmed flush with surface before tiling commences.

 · When laying Isocheck 32T in a kitchen or bathroom it is essential that additional support noggins are placed between the joists as well as the perimeter support referred to previously.

 · This is to support the higher loads imposed on the floor in specific areas.

 · Similarly these noggins will still need to be accommodated or considered during the installation of underfloor heating systems.

 · Especially where trays are used because the pipes may need to run under the noggin or the Isocheck 32T could be supported by steel strips that are screwed to the top of the two parallel joists.

 · If in doubt as to the configuration or quantity of support noggins additional advice should be sought to reduce the potential for undue deflection in these potentially high load areas.

 · Ceiling boards should be installed first, especially before any dry-lining of walls (such as dot & dab) to prevent potential flanking transmission.

 · Ceilings should be boarded with a minimum mass of 20kg/m², and must be fixed to resilient bars or suspended from a metal frame system in accordance with manufacturers recommendations.

 · If in doubt in any area, please call Isomass prior to commencement of work.
