26mm Isocheck RENOVO Acoustic Overlay Floor System is used directly over existing floorboards to reduce sound transmission through traditional joisted timber floors in refurbishment and conversion projects.

Isocheck RENOVO 2400mm x 600mm x 26mm acoustic overlay flooring platform system consists of 8mm environmentally friendly Ecopoli resilient layer bonded to 18mm 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.

Isocheck RENOVO has been tested by the NHBC for use in conversion applications and comfortably meets the required performance standards without a proprietary resilient bar or MF suspended ceiling system.

RENOVO’s resilient layer (ecopoli) contains 20% renewable vegetable based components with the added benefit of using less fossil fuel components in its manufacture.

A completely new catalyst enables castor oil to be employed in the production of low-emission polyols.

With castor oil accounting for 30% of the polyol’s total weight it can contribute to yet another renewable recipe to help our environment.

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

Health and safety, always wear correct PPE and use dust masks when carrying out any cutting operations.

Isocheck RENOVO Acoustic Overlay Floor Platform 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.

 · Ensure that all recessed down-lights or other invasive fittings have been correctly treated prior to closing off the sub-floor from above with the isocheck system.

 · If not confirmed of a solid construction all structural walls should be sealed both top and bottom prior to floor laying. e.g. lath & plaster wall linings, dot & dab systems, 'hollow' battened skirting's, etc.

 · Floor should ideally be 18mm chipboard, OSB, decking ply or original floorboards with a continuous layer of 100mm (45kg/m3) mineral wool insulation between the joists.

 · All nails and screws must be driven flush and securely fixed. 

 · The sub-floor should be level, sufficiently dry and swept clean to allow the Isocheck RENOVO to be laid flat.

 · All service penetrations should be isolated from and sealed to the sub-floor.

 · 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.

 · Isocheck must be kept in a dry storage area.

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

 · 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 boards are then pushed tightly together.

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

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

 · The Isocheck RENOVO 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 strips around the edge of the Isocheck RENOVO boards before pushing into position.

 · Remove any excess with a sharp knife, flush to the skirting face.

 · Stud partitioning should be built from the sub floor wherever possible.

 · If it is your intention to build off the top of Isocheck RENOVO 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 RENOVO 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 the 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 Isolation strip and trimmed flush with surface before tiling commences.

 · In a kitchen, we recommend that for best performance the kitchen units are installed on the sub-floor on pads, so that the isocheck 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 that for best performance 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 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 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.

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.


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.

2. Reviews

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.
