Application

It is suitable for use in new build timber frame projects, and can be used as an alternative to Robust Details.


Principal applications will be new domestic dwellings - houses and apartments constructed using timber frame where an enhanced level of sound insulation is sought in the separating floors.

Description

The HD1029 Hush System TF from Hush Acoustics is a sound insulation system that can be used as an alternative to Robust Details for separating floors in timber frame construction.


It provides a performance level that exceeds the minimum requirements for all UK Building Regulations - Approved Document E (England & Wales), Part G (Northern Ireland) and section 5 (Scotland).


Fire safety is provided through a 1 hour fire resistance at ceiling level.


How HD1029 is formed:


  • Hush-Panel 48 acoustic floorboards, all of which feature T&G joints glued using Hush-Bond, are laid over the floor deck as per manufacturer’s instructions, with all perimeters sealed using Hush-Seal 20.
  • Hush-Slab 100 acoustic insulation slabs are fitted between the joists with Hush-Bar Deep resilient bars - which is used to optimise acoustic performance by virtually decoupling the ceiling from the joists or a wall lining from the wall construction - fixed to the underside of the joists at 450mm centres and at right angles to the joists.
  • 2x layers of 15mm Soundbloc board are then secured to Hush-Bar Deep resilient bars, with all perimeters sealed prior to skimming.

 

Acoustic Performance*


Impact (L’nT,w) - 51 dB 

Airborne (DnT,w) - 58 dB

Airborne (DnT,w + Ctr) - 50 dB


* Results based on the full Hush System HD1029 being used within timber frame construction with a minimum of a 225mm I joist.
