Thanks for all the advice...... a few more questions....

Is it better to use an all in one foam underlay (which seems quiet
thin) or to lay a membrane and fiber board ? Does the two layers offer
better heat insulation and reduce noise ?

If you do membrane and then fiber board - does the membrane go down
first ?

Apart from the tools that seem to be on offer at all laminate
retailers what special tools might I need ? I've heard people mention
good saws - do I need an electric one ?

Thanks again
