Wood effect tiles upstairs

builder007

Before I tile, should I put some sound insulation first?

The floor is tongue and groove solid pine wood.

Never did this before... Any help would be appreciated.

Has anyone used the following product?

You cannot tile directly onto a t&g wooden floor as it will expand / contract depending on heating etc. Some of your options are to fit good quality 12mm plywood on top of the t&g boards , remove the boards and fit 18mm plywood onto the joists, or you could put tile backer board onto the floorboards , the tile backer board would provide sound insulation as well as a stable surface for tiling onto, make sure that the wooden flooring is properly fixed to the ceiling joists before you fix anything to it.

Thanks tabby. Very useful. What sort of sound insulation level/quality can I hope for if I go with tile backer boards?

Just to clarify. Im worried about impact not air borne noise... Cheers

A few people approached me recommending different systems.

1. Put down Magnesium boards
2. Pour some self leveling screed with good sound performance.

Hard to say which one is better. Any ideas?

- The house has no sound insulation at the moment.
- Solid pine wood T&N was laid on bare joists (no rubber strip)
- There is no rockwool in the cavity between the joists

If possible at all I would like to avoid ripping solid pine planks (to put rubber and rockwool) but I'm worried that I will waste money and time if I don't do that.

My current thinking is to leave everything as is and ADD the following:

1. Put some sound proof rubber mat (6mm) and seal with acoustic tape the connections.
2. Put a layer of plywood or something similar on top of it (please suggest alternative)
3. Put another rubbery underlay for tiling (acoustic)
4. Tile with wood effect tiles
