I was wondering if anyone knows the pros and cons of the above underlays for engineered flooring. I plan to put down a floating floor over concrete so I am looking for an underlay with a vapour barrier, which both of the above have provide. However, the Timbermate is described as a luxury rubber underlay with built in foil vapour barrier whereas the Tuplex consists of two layers of polyethene vapour barrier with flexible polystyrene granules sandwiched inbetween?
Many thanks, Bob
So what is your actual question?
"I was wondering if anyone knows the pros and cons"
Yes. No. Maybe. HTH.
Please stop hijacking posts if you don't know the answer.
I don't know what you're on about, old top. If you include context in your reply, and use plain English, it will benefit you (& others).
We're still waiting for the question.
I am looking for the "arguments for and against" using polystyrene/polyethene underlay as opposed to rubber/foil underlay for engineered flooring e.g.
rubber/foil is better for blah blah not so good for blah blah
and similar for polystyrene/polyethene
Many thanks Bob
Aha! Now I see. I'm not sure, though... perhaps the rubber stuff would not last as long as the polystyrene/polyethene stuff? What do *you* think?
Incidentally, "Kahrs Tuplex" sounds like a breed of Yorkshire Ram, from Bradford. Rams can be smelly. Is it a good idea?
Well I am not sure. The Timbermate is more than double the price of Tuplex but the latter is made by Kahrs so I presume is half decent. I wonder if they would feel different underfoot. Would the Tuplex feel more springy?
No offence intended - there's been a *leetle* pss-taking here. Please look at
It's an engineered (timber, I assume) floor. It's not going to feel much different whatever you put under it, it's not a carpet. If a point load, or even a footstep, deflects the floor to any appreciable degree, I think that would spell "trouble". I wouldn't have thought that a "luxury rubber underlay" would make one iota of difference.
Underlay between the flooring and concrete would add a lot of benefits. It would give the floor resilience. I don't know how flexible polystyrene granules would perform in the long term, so I'd go for the less expensive rubber and foil option.
