Would love to use Elastilon, but am advised against it.
Our "reach" online goes a long way.
I am planning to install 5/8" x 5 & 1/8" T&G Maple engineered hardwood flooring. I will be installing over concrete in a 20 year old home. An installer friend said I need to either glue down plywood and then nail the floor to this or glue directly to the concrete. I would like to use Elastilon as it sounds easier and would add some sound barrier and cushion. He said this will ultimately not work as you can not float a T&G Engineered Wood floor. It will buckle or gap after a few years.
In researching Elastilon, I am having trouble finding any good reviews, most say they like the concept but no one seems to have used it. I am stuck as to which way to go. Can you help? I am located in the US - California.
International Reviews on Elastilon
Thank you for your question. Your fitter friend is mistaken (but this can be down to regional difference in installation methods and experience of course). !5 x 130mm Wood-engineered can be installed using the floating method, if the boards are longer than 400mm average.
With Elastilon you do not really "float" the floor, the boards are truly stuck down - on the underlayment, not on the concrete floor.
Decision made - Elastilon it is
Based on your answers and some comments I received from others, I have decided to use Elastilon. My friend is not sure it was the right decision but since I will be doing most of the work, I am comfortable with it. I do not yet have the wood so have not started to install. I will let you know how it goes in about a month.
One concern I have is the largest room is 20 feet wide. Will this be OK? On one of your pages (I think, I have looked at a lot of information) I saw that the limit is 5-6 meters wide which puts me right there. Any thoughts?
Rules of Thumbs
The "rule of thumb" on that particular page is for Solid (Oak) flooring, with wood-engineered boards you're good up to 11 meters wide.
(Side-note, do keep in mind these rules ar on width of the actual wooden floor, not just on the width of the room. See also our article "Keeping your wits about widhts!"
Thanks for your help. I will let you know the outcome next week.

Here are a couple of pictures of the first room in the works. I think it turned out rather well considering it was our first try. I particularly like the way the floor has a slight “spring” to it so it does not feel so hard when you walk on it.
