Acoustic Underlay for Wood Lamninate Flooring
Hi all,

I am moving into a 1st floor flat which is quite old and one of the covenants is that I must put in a carpet (not to disturb the people below).

However we love a wooden floor from Ikea which comes with 4mm underlay. Do you think this would be sufficient enough to dampen the sound? Is it possible to put double the amount (2*4mm) and would this make a considerable difference in the sound absorption.

Many thanks

Silent flooring
We have Ikea wooden flooring and have used the slightly thicker (6mm) green fibrous type insullation undernieth. We don't hear any noticable noise from feet on the floor, just the odd breaking cup, child leaping off the bed onto the floor etc. However, if someone wanted to be awkward they may insist that you follow the rules regardless. Good luck...John

a better pad makes a good difference.
If you want to find Cork underlay, that really works well. IF the manufacturer approves.

Thats great, thanks for reply.

Does Cork really work then?

Do you think it would work if I put twice the amount the IKEA underlay?

I think some kind if rubber would be the best but have no idea where I could get it!

I'd use 8-12 mm cork underlayment. Great sound absorption, resilient, fire retardent, and from a renewable natural source.

I didn't know cork was a fire retardent! Cork is probably the most expensive option isn't it? Are there any fiber options that are thicker than 6mm?

Yep, it's a natural fire retardent; in fact, it has a class II fire rating. And yes it is a bit more expensive, 6 mm will run you about $1.25 per square foot, 8 mm about $2, and 12 mm about $2.50. If it's a place you're not staying in long term, you might want a cheaper option.

I too have an HOA restriction and want to put laminate floors in. I live on the second floor which is concrete believe it or not. I would think the concrete would be somewhat less sound conducive, would it not? Anyway, does this change anyone's answers to the man that originally posted the question?
