75mm Isocheck Deep Batten 75RD is a suspended floor system specially designed for timber and steel frame floors and can be used in conjunction with underfloor heating systems.

Deep Batten System is designed to be used over timber floors with a timber frame or masonry facade (to hide services or accommodate underfloor heating beneath the floor).

Isocheck Deep Battens can be also used in new resilient bar ceiling for new build timber frame or steel frame projects, refurbishments and conversions.

1800mm x 45mm x 75mm Isomass Isocheck Deep Batten System consists of a layer of 15mm ACF (Acoustic Chip Foam) bonded to a FSC-certified 60mm softwood batten.

When installed as part of a complete party floor construction it enables a concrete floor to meet the sound transmission standards of ADE 2003 and subsequent amendments.

Isocheck Deep Battens may be installed in conjunction with underfloor heating UFH systems and other floor constructions.

Treated floor meets with the New Build Robust Detail descriptive FFT1, typically within Robust Detail E-FT-1, E-FT-2, E-FT-3, E-FT-7 and E-FS-2.

Flanking Strip should be installed with batten and turned back under skirting and trimmed flush with a sharp knife.

 · Meets the sound transmission standards of ADE 2003.

 · Meets with the New Build Robust Detail descriptive FFT1.

 · Suitable for conversions, refurbishments or new build projects.

 · Reduce impact vibration leaking.

 · Reducing airborne sound paths.


75mm Isocheck Deep Batten 75RD System Installation Guidelines:

 · The sub-floor is to be swept free of any loose debris leaving a smooth surface on which to place the isocheck Batten.

 · The building must be weatherproof and completely dried out before commencing installation of the flooring system.

 · It is most important for the reduction of airborne sound to block any air passage in the structural floor, at the perimeter of the floor and wherever the floor is penetrated.

 · Any flooring components exposed to wet conditions should be replaced.

 · The location of services should be detailed at an early stage.

 · Services should be kept at least 150mm away from walls to allow space for perimeter bearers.

 · Do not place large quantities of material such as chipboard or plasterboard on top of laid flooring as this extreme loading can damage the resilient layers.

 · All components should be kept inside, and in dry conditions at all times.

 · Risks can be significantly reduced by good detailing and the use of modern flexible adhesives.

 · When laying ceramic tiles on floating floors please contact us for advice.

 · Where lightweight non-load bearing partitions are built from the top of the floating floor a double row of isocheck Deep Battens should be placed beneath the partitions.

 · Alternatively, if the line of a partition is not supported by a structural joist a supporting ladder frame of Deep Battens should be created.

 · The structural performance and location of partitions should be in accordance with the recommendations of the timber kit supplier.

 · All isocheck Deep Battens must either be laid directly above the main floor joists running in the same direction or be laid perpendicular to the direction of the structural joists and be supported by them.

 · Lay Deep Battens around the perimeter of the room approx. 50mm from the wall.

 · Battens should then be laid at 400mm centres under normal domestic loading.

 · In a timber frame construction load bearing partitions are constructed prior to the installation of the acoustic flooring.

 · Mark the desired location of any non load bearing partitions.

 · Lightweight non-load bearing partitions can be constructed from the timber deck providing all necessary noggins and supports are located before fixing of the timber sub floor.

 · Start each alternate row of Deep Battens with a cut length so that joints are staggered leaving gaps at the ends.

 · Where services run across battens - do not notch.

 · Cut Battens and place approximately 25mm either side of the pipe.

 · Decrease the Batten spacing to between 200 & 300mm apart directly below isolated heavy loads such as bathroom and kitchen furniture and appliances.

 · Place isocheck Deep Batten across each doorway so as to form a ladder frame to provide extra support.

 · Ensure that a gap is left between the bottom of door frames and the top of chipboard flooring.

 · Where non load bearing partitions run perpendicular to the structural joist line or run directly above the line of structural joists - place double rows of Deep Battens to provide additional support.

 · Alternatively, if the line of a non load bearing partition is not supported by a structural joist a supporting ladder frame of Deep Battens should be created.

 · Lay the plaster plank across the Deep Battens in a brick-bonded method ensuring that all short edges of plank rest centrally on a batten.

 · Leave a clear 10mm gap at the perimeter.

 · Fix the plank to the bearer using gypsum nails long enough to securely fix the plank but not so long as to bridge the Battens resilient layer.

 · The plank should be surface nailed with a minimum of three nails across the face.

 · 18mm thick chipboard should be used where bearers are at 400mm centers and normal domestic loading is anticipated.

 · Ensure that the edge joints of the chipboard do not coincide with the edge joints of the plank.

 · Short edges of the chipboard should always rest above the Deep Battens.

 · Fix the chipboard using annular ring shank nails or screws, with four fixings across the width of each board.

 · Fixings should be a minimum of 2.5 times the thickness of the board and longer if plank is in use.

 · Care should be taken to ensure that the resilient layer on the bottom of the bearer is not bridged.

 · All tongue and grooved joints must be glued continuously with adhesive on both the top of the tongue and bottom of the groove on each side of the joint.

 · All joints must be tightly butted and excess glue removed with a damp cloth.

 · Ensure that gaps where services come through the flooring are sealed with acoustic sealant to prevent airborne sound leakage.

 · Position the isocheck Flanking Strip in the perimeter gap adjacent to the perimeter wall.

 · The preformed `L` shape will prevent it from falling down the gap.

 · Fix the skirting board , lightly trapping the strip between the bottom of the skirting board and the flooring.

 · Remove any excess Flanking Strip with a sharp knife.

 · It is essential to isolate the skirting from the floor to prevent impact sound flanking transmission.

 · The Flanking Strip should not be removed on completion.

 · In areas where heavy loadings are anticipated, such as kitchens and bathrooms, the bearer centre's should be reduced to between 200 & 300mm.

 · In cases of extraordinary loading advice should be sought from the specifier or manufacturer.

 · Isomass Technical Department is available to provide advice where required.

 · Providing they are preplanned , the provision of access panels is simple.

 · Panels should be square edged and supported along all edges by isocheck battens.

 · Access panels should be screwed down and sealed with acoustic sealant.

 · Storage heaters are considered to be an extraordinary loading and may require support direct from the subfloor, independent of the flooring system.

 · Contact Isomass Technical Department for advice if required.

 · The need for intermediate expansion gaps between sheets of chipboard must be considered where there are uninterrupted runs of flooring more than 5 metres in length.

 · Expansion provision should be calculated at a rate of 2mm per metre run.

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.



We are the stockist of construction materials and related products for both trade and DIY from most recognizable brands in the UK like Cordek, RCM, Promat, Rockwool, Isover, Celotex, Xtratherm, Ursa, Low-E, Cedral, Kingspan, Dufaylite, British Gypsum, K-rend, Ecotherm, Iko enertherm, Kay-Metzeler, Terrawool to allow you to complete your insulation job on time at competitive prices and the highest standards.
