Cradle adjusters with Hush Insulation

The Level-It Floor Cradle System was developed in order that a level finish could be achieved on uneven floors or cambered sub-floors. The system is Document E Compliant and will help achieve impact noise and airborne noise sound requirements as laid down in document E of the building regulations.



Acoustic Cradle

Floor Cradle - Level It

Whisper Acoustics developed the Cradle System as a Levelling System for flooring within the Construction Industry.

Working in conjunction with Hush (UK) Ltd, they found the System had excellent Acoustic values when used with a Hush (UK) Ltd Acoustic Pad.

The System enables a 50 by 50 timber batten to be placed in the Cradle and the floor to be levelled easily in 1mm increments. The addition of the Hush (UK) Ltd Acoustic Pad enables the Cradle to meet the requirements of Document E Building Regulations.
