HD1044 Hush Basement System - Acoustic Floor and Ceiling System

The HD1044 Acoustic Basement System from Hush Acoustics is an ideal acoustic solution for providing sound insulation in basements within residential conversion and refurbishment projects.

This fully tested, complete system combines Hush Acoustics' advanced sound insulating materials to reduce the transmission of sound from the rooms above basement areas.

Providing enhanced acoustic insulation using the HD1044 system unlocks the potential for basements to be used as living/sleeping spaces as they will be insulated from noise sources above. In addition, this acoustic system is compatible with purposes where loud noises are likely to be generated – such as a cinema room – without creating excessive noise in the floors above.

HD1044 is compliant with all UK Building Regulations relating to the passage of sound in buildings - Approved Document E (England & Wales), Section 5 (Scotland) and Part G (Northern Ireland).

How the HD1044 system is formed:

• The floor is removed and Hush Slab 100 Sound Absorber panels are fitted between the floor joists. These slabs are tightly packed between the joists to ensure there are no gaps. The floor can then be replaced.
• On the ceiling side, Hush Deep Resilient Bars are fixed horizontally to the underside of the joists at 600mm centres.
• Hush Multi Panel is installed to the underside of the Hush Deep Resilient Bars, over-boarded with 15mm Fireline plasterboard.

Acoustic Performance*

Impact (L’nT,w) - 52 dB

Airborne (DnT,w + Ctr) - 48 dB

* Results based on all Hush materials listed in the Hush System HD1044 being used. Results are also based on 200mm timber joists and all flanking junctions being treated.
