Acoustiblok 3mm Sound Isolation Membrane

Acoustiblok 3mm sound isolation material is used as a structural treatment for reducing sound transmission.

Key Facts:

    Thickness: 3mm (0.3cm)
    Weight: 4.88kg per square metre (psm).
    Roll Sizes: 25.09m² rolls.
    Roll Length – 18.29 metres (60′).
    Roll Width – 1.37 metres (4’6″).
    Roll Diameter – 260mm.
    Acoustic Performance: Sound Reduction Index (SRI) rating of 26dBA – six decibels more effective than lead at the same thickness.

Uses: Acoustiblok 3mm membrane is invariably used within wall and ceiling installations as well as applications such insulating bulkheads within boats, even pipe lagging and when dealing with airborne/structural airborne sound levels. Acoustiblok can also be used to defend against impact sound within floor insulation treatments when required.

Acoustiblok contains no lead or asbestos materials and is typically applied as part of a layered wall or floor construction, either tacked to the studs prior to drywall or draped over joists before sub-floor.

Acoustiblok reduces sound transmission through a unique process known as thermal conversion, where problematic sound waves are converted into trace element heat waves via molecular movement and friction and dispersed sideways through the material. It provides a highly effective solution across differing frequencies, including problematic low frequencies under 100HZ.

Acoustiblok is UL (Underwriters Laboratories) approved in walls, floors and ceilings. It is impervious to water or moisture, very flexible and cuts with a box knife. It can be nailed, stapled or glued and is non corrosive, and temperature tested up to 200 degrees. Acoustiblok will not mildew – ideal for basements or in attics – and will not compress under carpet and is highly UV resistant. In addition to walls and floors, ceilings, doors and even window blind systems are also suggested treatment areas to further reduce sound transmission.
