Laminate floor bounce problem, why?

The most straightforward answer of laminate floor bounce problem is: because the subfloor isn’t flat and/or level enough. But what is “flat” and what is “level”?

“Flat” refers to the bumpiness of a floor. A perfectly flat floor is difficult to achieve. But the laminate floor of today need a subfloor that is as close to “flat” as physically possible. There are several ways to classify “flat”. The National Floor coverings association (NFCA) has five (5) classifications. These range from “Conventional” through to “Super Flat”. The easiest way to understand these classifications is to imagine a 10 foot long “straight edge” laid over a floor. The bumps and ripples in the subfloor will cause either hills or valleys. The space underneath is called a gap. The “gap” is what you measure to determine how flat your subfloor is.

The bigger the numbered ranking, the better the subfloor is. The #5 “Super Flat” is a much better subfloor than the #1 “Conventional” subfloor:

  • Conventional: defined as 13mm gap over 3000mm (10 ft) of floor space. This means there is as much as ½ inch of gapping between one end of the 10 foot straight edge and the other end.
  • Moderately flat: 8mm (5/16 inch) gap over 3000mm (10 ft).
  • Flat: allows 6mm (1/4 inch) over 3000mm (10 ft).
  • Very Flat: 4.5mm (3/16 inch) over 3000mm (10 ft).
  • Super Flat: only 3mm (1/8 inch) over 3000mm (10 ft).

Now that “flat” has been defined, anyone can follow the professionals’ installation instructions. Keep in mind these are technical specifications that allow the floor to “stay together” without floor failure. This has nothing to do with customer satisfaction. These numbers are for warranty purposes ONLY.

Some examples of subfloor requirements for Name Brand flooring products:

Pergo Laminate – Installation requirements = “no low spots greater than 3mm over 1m and no peaks higher than 1.2mm in a 250mm radius”. Huh? Right. Put that into the numbers used above. It turns out the lowest spots = 9mm over 3000mm and no peaks higher than 14.4mm over the same distance. That’s very forgiving flooring. Don’t attempt to reach these numbers – but it is the only way to compare X deflection over Y distance. This would rank somewhere in the “Conventional” range. The floor will stay together under these circumstances but if you follow these allowances, the floor is most certainly going to move.

Forna Floating flooring = the floor must have no more than 3mm of gapping/deflection over 1000mm. That means there is a 9mm of deflection allowed over 3000mm (10 ft). Forna flooring requires a “Moderately Flat” subfloor.

Lumber Liquidator’s Laminate Products (all of them) – “Subfloor must be flat with 3/16 inch within a 6 foot radius”. Translation into metric (which is what we are using): 4.75 mm over 2000mm distance. And again into the stated lingo: 7mm over 3000mm. That means the subfloor falls into “Flat” range.

Anything other than “flat” and this floor is going to fail – or at least “walk itself apart” when the lock system disengages.

The second part of the equation is choice of underlayment or under pad. A low density, compressible foam underlay is going to allow the floor above it to sink into the padding. This sinking feels like bouncing. A high-density, non-compressible underlay (such as cork, solid rubber, woven fibre, etc) does not allow the floor to sink into it. This non-yielding underlay gives the floor a solid feel to it; without the bouncing or clicking that is so irritating.

Enough Forna clients have opted for the low-density, low cost option to report back to us regarding the “feel” of their floor. They complained that the floor bounced – which is not what they had been expecting when ordering a cork floating floor. One client was so upset that he removed the cork floor, removed the foam underlay and replaced it with cork and then reinstalled the floor. He was so impressed with the feel under his feet he contacted Forna to tell them the difference and how happy he was he changed out the underlay.

This story just goes to show that, “A floor is only as good as the material it sits on”.
