HD1029 Hush System TF

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.
