23mm Isocheck 23C for Concrete Floors is an overlay screed board system specially designed to reduce impact sound transmission through concrete floors, suitable for new build, refurbishment and conversion.
Acoustic Overlay Isocheck 23C system does not need the additional protection of a moisture barrier (VCL) vapour control layer because the Isopoli foam will not absorb the moisture from a virgin screed.
Concrete Floor System Isocheck 23C 2400mm x 600mm x 23mm consist of a 5.5mm thick layer of cross linked Isopoli foam bonded to 18mm P5 V313 moisture resistant chipboard.
When installed as part of an Isomass approved party floor construction it enables a concrete floor to meet the sound transmission standards of Approved Document E 2003 and subsequent amendments.
Acoustic Floor System for Concrete Floors Isocheck 23C can be used over concrete floors for conversions, refurbishments or new build with a new ceiling.
Isocheck 23C Flooring System for Concrete floors may also be installed in conjunction with underfloor heating systems.
The finished Isocheck 23C system should be protected with an appropriate layer immediately after being installed to prevent damage.
The 23mm Isocheck 23C fully complies with new build robust detail descriptive FFT5 within E-FC-1, E-FC-2 and E-FS-1.

23mm Isocheck 23C Acoustic Overlay Floor System Installation Guidelines:
· The presence of steel work, lift shafts and even ceiling penetrations can often impair acoustic performance.
· If any of these (or other issues not previously declared) are present on your site, please contact us for additional advice.
· Floor should be a level screed / concrete with a smooth surface, or an in-situ concrete base.
· The floors should be level, sufficiently dry and swept clean to allow the Isocheck 27C, 23C, 18C or 14C to be laid flat, without any irregularities of sufficient height to bridge the resilient layer.
· Installation of isocheck 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.
· 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 and then the boards are then pushed tightly together.
· Surplus adhesive should be wiped away from the surface with a damp cloth.
· Isocheck 27C, 23C, 18C & 14C must be kept in a dry storage area.
· Deliveries should be scheduled to coincide with availability of suitable dry storage areas.
· Door openings should have linings fitted prior to the installation of the acoustic floor.
· The Isocheck 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.
· To prevent flanking transmission all skirting must be isolated from the floor surface.
· Before incorporation, place isocheck Flanking Strip around the edge of the Isocheck 27C, 23C, 18C & 14C boards before pushing into position.
· Stud partitioning should be built from the sub floor wherever possible.
· If it is your intention to build off the top of Isocheck 27C, 23C, 18C & 14C additional advice should be sought.
· It is good practice to isolate all partitions built from the sub-floor with Isocheck Flanking Strip as this will improve the performance of the walls as well as the floors.
· 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 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.
· After the skirting board is installed, simply trim the Flanking Strip flush with a sharp knife.
· The finished Isocheck 27C, 23C, 18C & 14C 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 floating floor.
· Should be isolated by cutting a hole up to 10mm larger than the service diameter and filling the gap with an acoustic sealant.
· Ideally kitchen worktops should be isolated from the wall with Impacta pads and trimmed flush with surface before tiling commences.
· In a kitchen, we recommend the kitchen units are installed on the sub-floor on pads, so that the isocheck boards can terminate at the legs of the units.
· The plinth can then be installed to the kitchen unit legs, making a neat, flush finish.
· Lay the floor in areas where appliances will sit, allowing for adequate height below the work surfaces.
· If installing the units on the floating floor additional advice should be sought to reduce the potential for unwanted impact flanking noise.
· In a bathroom, we recommend the bath should be supported from the sub-floor on isolation pads, and the floating floor terminate at the legs of the bath as close as possible.
· The bath panel can then be installed making a neat, flush finish.
· Plywood the same height as the Isocheck should be laid under the bath, toilet and wash basin area and the joints filled with silicon or an alternative acoustic sealant where necessary.
· 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 10kg/m², preferably with a minimum void of 75mm and 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.

No matter whether you choose a local installer or a national company, there’s a few tips to help you find the right installer for your home insulation improvements, such as asking for recommendations and making sure that they’re part of a certification scheme. This makes sure that they have the right skills and standards of workmanship to carry out the installation, and you can be sure that they know exactly what they are doing.
4 TIPS FOR CHOOSING THE BEST INSULATION INSTALLER
1. Thermal inspection picture in portfolio
It’s worth seeing a installer’s previous work. There’s no harm asking if you can see any properties nearby that they’ve installed insulation in. Best way would be to see Infrared Thermal Imaging Inspections. Thermal cameras spot small, but key changes in temperature in different areas of a house, identifying problematic areas that the human eye never could and some that a visual inspection could only hypothesize.
Along with checking recommendations and previous work, finding reviews online can often be a great way to find out if they provide a good service or not. However, it’s best not to solely rely on reviews you may find or review websites, as there’s no controlling who writes them.
3. Compare prices
Comparing prices will also ensure companies can’t take advantage of you and give you a fair price.
4. Word of Mouth
The best way to find a great insulation installer is through recommendations. Make sure you ask friends and family. They will most likely give you their honest opinion and can tell you from first hand experience.
Whether you require a wall, cladding, external wall, loft or floor insulation fitted, you can find and hire your local insulation installers from popular UK web pages. A simple internet search will return thousands of potential installers near your area.
