ᐅ Luxury Vinyl Flooring: Floating Installation or Glue-Down?

You can see this very clearly with vinyl flooring, even when it is glued down. Just let the sun beat down on it from the south side... The adhesive cannot withstand it, and the floor buckles. I have seen this with my own eyes, and every experienced floor installer knows how much vinyl expands or contracts. When you glue it down, the stress has to go somewhere...

So obviously, there is no clear consensus here either.
We are installing underfloor heating throughout the entire house and have chosen a Joka Classic.

I would definitely not glue vinyl flooring onto underfloor heating! That causes so many problems... Vinyl flooring expands and contracts much more than wood, and if you add sunlight exposure in summer, a wavy floor is almost guaranteed!

Complete nonsense, absolutely not true

Sorry, that’s nonsense. I have installed vinyl flooring glued down in several houses over the years—without any problems. Every flooring professional has always recommended gluing it, especially where we had underfloor heating.

Of course, that doesn’t make sense. Vinyl shouldn’t be installed on an HDF substrate either, because it would warp when exposed to sunlight.

So, two specialist stores actually recommended gluing it down to us. Especially because of the underfloor heating, as the heat transfer is supposedly better with glued flooring. Plus, you can easily replace a single plank if something happens.

I'm not sure, but is it allowed to install click flooring in large rooms in one continuous area? I vaguely remember that with click systems, there’s a limit on the surface area. But again, I haven’t researched this thoroughly.

We’ve already installed click flooring nicely; I imagine that gluing it won’t be more complicated. Click laminate is definitely easier to install with the locking system. Maybe it was just the manufacturer [emoji848] Although it wasn’t a cheap floor.

Well, we’ll see how the gluing goes and if any waves appear.
