A quieter floor with space for services

Hush Batten 55 creates a service void beneath the floor deck for pipes, cables or underfloor heating. It is ideal over concrete floors in flats and apartments, and suitable for domestic, residential, education and healthcare projects.

Hush Batten 55 helps meet Building Regulations Part E in England & Wales, Section 5 in Scotland and Part G in Northern Ireland. Suitable for use in Robust Details floor systems.

Choose the correct batten centres

• 18mm chipboard or timber flooring: maximum 450mm centres.
• 22mm chipboard or timber flooring: maximum 600mm centres.

How to fit Hush Batten 55

1. Loose lay the battens felt side down in continuous rows at the correct centres. Keep perimeter battens at least 25mm from the walls.
2. Lay the flooring with a 10–15mm expansion gap at all perimeters.
3. Glue and fix the floor boards to the battens using ring nails or screws that do not pass through the resilient layer.
4. Glue all tongue-and-groove joints with Hush Bond panel adhesive.
5. Seal the perimeter gap with Hush Seal 20 so the floor floats freely.

How many battens do I need?

Calculate the number of rows by dividing the room width in millimetres by the chosen batten centres, then adding 1. Round this up to a whole row. Divide the room length in metres by 1.8 and round up to find the battens per row.

Multiply the rows by the battens per row, add about 10% for cuts, then round up to a whole batten.

For a 4m-long x 3m-wide room at 450mm centres:

• Rows: 3000 ÷ 450 + 1 = 7.67, rounded up to 8 rows.
• Battens per row: 4 ÷ 1.8 = 2.22, rounded up to 3.
• Base quantity: 8 x 3 = 24 battens.
• With about 10% for cuts: 24 x 1.10 = 26.4, rounded up to 27 battens.

Need a deeper service void?

A deeper Hush Batten 70 is available where you need more room for services beneath the floor.
