Product Information
Level uneven floors while adding resilient support beneath your timber battens. Hush Cradle Felt 70mm Acoustic Batten Cradle uses a threaded support ring for precise adjustment, helping you create an even acoustic floor without stacks of loose packers.
Use Hush Cradles over concrete or timber in new builds and refurbishments. The raised batten layout also creates a useful service void beneath the floor deck.
90 cradles per pack · 90mm diameter x 70mm high · 10mm Hushfelt resilient base
Adjustable support for an even floor
Turn the O support ring along the thread to level each batten, then lock the carrier upstands against it. Hush lists the adjustment as 15–60mm above the structural base; the overall cradle height is 70mm.
The bonded felt base provides resilient separation to help reduce impact transmission. Hush’s HD1031 floor and ceiling system incorporating these cradles reports 50 dB L’nT,w impact, 58 dB DnT,w airborne and 53 dB DnT,w + Ctr.
Centres and installation
- Follow the specified batten layout. Hush’s HD1031 detail uses 47 x 50mm timber battens supported on cradles at 450mm centres.
- Place each batten joint over a cradle and support the ends of the runs. Keep perimeter battens and cradles at least 25mm from walls.
- Adjust the rings to level the battens and lock the carriers.
- Glue and fix the floor deck to the battens, bonding the tongue-and-groove board joints with Hush Bond.
- Leave a 10–15mm deck perimeter gap for Hush Seal 20, or use the specified Hush RD Flanking Strip detail.
Considering a separate acoustic batten?
See Hush Batten 55 for a batten with its own resilient backing. The cradle detail above specifies 47 x 50mm timber; check any substitution before ordering.
How many do I need?
Count all cradles in the planned batten layout, including joint and perimeter supports. Divide by 90 and round up to whole packs.
For example, six batten runs requiring 10 cradles each need 6 × 10 = 60 cradles. That is 60 ÷ 90 = 0.67, rounded up to 1 pack of 90.
You’ll also need
Plan adhesive from the floor area and perimeter isolation from the room edge measurements. Choose the specified perimeter detail: Hush Seal 20 and Hush RD Flanking Strip are alternatives.
For example, a 5m × 4m room is 20m² with an 18m perimeter: allow 1 adhesive bottle and 2 lengths of Hush Seal 20, or 1 roll of Hush RD Flanking Strip where specified. Allow extra for cuts, joints and awkward edges.
