Acoustic Systems

For Concrete Floors

Our goal is to simplify acoustic flooring specification, nationwide.

NZBC G6 requires that multi-tenant residential buildings perform at certain acoustic levels. Traditionally these requirements are met with a suspended floor system and a drop ceiling. Woodland Lifestyle has developed two acoustic floor systems that eliminate the need for these complex and costly requirements, reducing the floor build-up, cost, and complexity whilst giving clients greater design freedom.


The SoundLite system utilises our 8.5mm Metrofloor hybrid flooring system and the high performance acoustical 1mm underlay -floorMuffler.


Metroflor Genesis Flooring is a multi-layer luxury vinyl plank comprising multiple layers of vinyl, an engineered closed-cell extruded structural core, high-resolution printed decorative film, and a sound-mitigating underlay. Metroflor Genesis planks utilize a Droplock 100 locking system and are laid as a floating floor. The wear layer is similar to that of regular commercial grade glue-down vinyl.


FloorMuffler LVT is a thin high-performance flooring underlay designed to be used with glue-down and ridged core vinyl planks. FloorMuffler LVT is a patented design made with cross-linked polypropylene foam and is 100% recyclable.

Technical Specifications

System Details

Woodland Lifestyle and our supply partners have conducted both laboratory and onsite tests on various slab thicknesses.
We recommend using SoundLite on slabs with a minimum thickness of 170mm without a drop ceiling. Metroflor flooring is suitable for wet areas including bathrooms, kitchens and laundries.
