Isosonic DekFloor 30 is a direct to joist acoustic flooring system for refurbishment projects. It comprises Isosonic Dek 30, a combined structural deck and acoustic insulation, with an isolating ceiling treatment.
The Isosonic Dekfloor 30 system combines an acoustic insulation and structural timber deck, reducing installation time and overall floor depth. It is ideal for refurbishment projects, as floor heights are not drastically altered to incorporate the acoustic insulation.
Test results will vary for each floor type.
Site test performance: Impact = 59dB LnTw
Airborne = 50dB Rw + Ctr
Find out more about this system, read an in depth report, and see our carefully curated instructions on how to get the best results when installing your solution.
The Isosonic Dekfloor 30 system consists of 30mm Isosonic Dek 30 boards fitted directly over timber floor joists. This makes it ideal for refurbishment projects where the floor boards are being replaced and a new acoustic floor is required.
To achieve Part E compliance 100mm thick low density mineral wool is required between the joists with an Isosonic Ceiling treatment below.
An Isosonic Ceiling is also required, consisting of Isosonic Cleats with an MF ceiling system.
Alternatively, Isosonic Hanger or Isosonic Bracket systems can be used. All ceiling systems are under drawn with a layer of 12.5mm plasterboard and either a layer of 19mm plasterboard plank or 15mm Soundbloc board.
Isosonic Dek 30 is a 30mm thick structural acoustic floating floor comprised of 22mm P5 chipboard that is bonded to an 8mm thick dense rubber acoustic layer. The chipboard layer has T & G joints that should be bonded with Floorbond adhesive.
The P5 chipboard used in the production of Isosonic Dek 30 is sourced from sustainable supplies. Isosonic Dek 30 has a Global Warming Potential of Zero and an Ozone Depletion Potential of Zero.
Floorbond Adhesive is a low viscosity water resistant wood adhesive used to bond the T&G joints of Isosonic Dek 30. It is fast setting, will not discolour overlays and has good heat resistance.
Isosonic Cleats provide acoustic separation to a standard MF ceiling construction. A universal fixing, they simply replace the standard soffit cleats and should be compatible with all MF ceiling constructions.
Isosonic Ceiling treatments utilise Isosonic Hangers or Isosonic Brackets to separate the plasterboard from the joist. This extensive range of acoustic hangers and brackets provide the flexibility to design a ceiling to suit most situations.
The Isosonic Hangers are attached to the bottom or side of the joists and hold 50 x 50mm battens which the plasterboard is then fixed into. An acoustic foam or rubber layer within each hanger isolates the battens from the joists, reducing direct sound transfer between the joist and the plasterboard.
The Isosonic Brackets are attached to the bottom of the joists and hold 50 x 50mm battens or standard metal channels which the plasterboard is then fixed into. Specially designed rubber fixings isolate the brackets from the joists, reducing direct sound transfer between the joist and the plasterboard.
