HD1029 Hush System TF Acoustic Insulation in Timber Frame Construction

HD1029 Hush System TF from Hush Acoustics is a reliable sound insulation system that can be used as an alternative to Robust Details for separating floors in timber frame construction with performance that exceeds the minimum requirements for all UK Building Regulations - Approved Document E (England & Wales), Part G (Northern Ireland) and section 5 (Scotland).

An economic sound insulating solution, it is proven to perform effectively as it has been tested as a complete system and is formed in the following way:

• 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 the fitted between 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.
• A 19mm Plasterboard plank and 12.5mm Soundbloc are then secured to Hush Bar Deep resilient bars, with all perimeters sealed prior to skimming.
