Room Soundproofing

PhoneStar Soundproofing Board

Reduce the Impact of Sound Transmission

We provide soundproofing solutions for residential or commercial buildings

As apartment living has become more practical, the need to reduce sound transmission in 2-story dwellings has become increasingly important to inhabitants. Consideration for creating spaces conducive to working from home is important for new builds along with easily achieved retro-fit options for existing dwellings.

Room soundproofing solutions involve using building products with mass to reduce the effects of impact sound such as footsteps and airborne sound – music, talking and television travelling through floors and walls.

PhoneStar is a room-soundproofing solution, proven in Europe that Woodland Lifestyle have brought to New Zealand.


PhoneStar is Quality German Made Soundproofing Board.

PhoneStar Tri is a versatile high-performance acoustic insulation panel. Made from a combination of sand and cardboard, it is designed to reduce both impact and airborne sound while adding thermal mass to structures.

Easy Installation
It can be fitted onto new studs, or fixed over existing walls or under floor coverings. For optimal performance it can be decoupled from the existing wall (becomes a wall within a wall).

It is ideal for noisy neighbour problems, rumpus rooms, boardrooms and offices.

Installing Phonestar can be undertaken by a competent DIYer.



Plan your install. PhoneStar sheet sizes are 1200mm long x 800mm wide. Its important to cut for a firm fit as gaps will transmit sound.



PhoneStar can be cut with a saw, or with a knife. Cut edges must be sealed with PhoneStar Eco Tape, to prevent the sand spilling out.



PhoneStar is fixed horizontally using standard drywall screws. After installation, seal any gaps with an acoustic sealant before lining with the final wall covering.
