Junckers 14mm wooden floor [b]creaking[/b] when using clips

[Junkers88]

Does anyone have any recommendations or words of wisdom, advice or encouragement...?

I chose Junckers 14mm wooden flooring because of the wonderful colour and rich patterns of its "Umbra" style. When laid it looked fantastic. However, the installers first nailed it to a Weyroc floating floor - big mistake, I thought: the creaking was bad, there was 'bouncing', and worse, as the nails came loose (they don't hold in chipboard-like Weyroc) it would only get worse.

By way of a solution, I demanded the floor be re-laid (it came up fine; the installers grumbled plenty), and this time a 6mm insulation board (with 3mm give, to soak up the discrepancies of the certainly-not-flat Weyroc) was put down. Then, at the recommendation of Junckers UK, I chose to use their special clips to hold the boards together.

The result? Well, at present there certainly appears to be more 'give' (I might open it to the public as a bouncy castle) and just as noisy. Argh! The difference between this and the nailed-down floor is that I hope this can only get better. I was told by Junckers that it might take a floor up to 12 months to 'bed down'. I'm not going to hold my breath, but I will live in hope.

I do think your subfloor is causing the problems. Bouncy underfloor/subfloor means the rigged wood floor will creak.
No matter how you install the wooden floor, the subfloor has to be suitable. And IMHO that isn't the case here.

subfloor as woody has said. But also if they have used the same wood as they took up you will or should i say, may have have broken tongues where the nails used to be. This can cause noise too.

Just seen it again and had a good walk around on it and I'm really annoyed - it's so much worse that when it was nailed down!

Thanks for both your responses and opinions.

I'm sure the nail damage to the tongues/grooves is minimal but it could be a contributory factor. But as you both agree, it's the subfloor that's the main problem. I thought that underlay would take out the 3mm or so variation in the Wayroc, and I'm praying it will still do so in time.

Otherwise, what a waste of money. I'm gutted.

how much does the floor run out? 2mm in a meter ? more?

 

[Junkers88]

Sorry, not familiar with the term 'run out'. What do you mean?

Junckers have agreed to send out one of their experts to see it now, incidentally.

And going back to the subfloor as being the villain of the piece, while it hasn't helped, the situation now appears to be that the wood is doing what it likes independently of what's beneath - i.e. it's rising not in line with the wayroc but just because of the way it's lying and held together by these stupid clips.

It still sounds like I'm walking around on the deck of the Black Pearl...

if you put a 2 meter straight edge on the floor how much of a gap do you get between dips in the floor and the straight edge ? ( run out )
Also i must say that the junkers Stupid clips, Are not that stupid when fitted correct. I have fitted thousands of meters of junkers with out a problem. In fact they are very clever clips that allow expansion for the floor which you match to your humidity of your house. If you look at the clips the will have a hole or two or even three in them. This indicators which clip it is. 1 hole for low humidity, 2 holes for average humidity and 3 holes for high humidity. The clip spaces the boards apart correctly for the amount of humidity you are fitting the floor to. Hence very clever really!

Junkers clips help by expansion/shrinkage, and have nothing to do when your underfloor is uneven or bouncing all over the place. Wood is a rigid material and can't flex very much to the surface underneath, hence your creaking.

Has your floor "bedded down" at all.. I am installing this system on a concrete slab and have creaking problems

it is a floating floor...not nailed down..just clipped

 

[chappers]

there is only one problem here and that is that you have an un fixed sub floor causing all this bounce and if it isn't perfectly flat the problem could be made worse by flexing in your new floor.
fix the sub floor fix the problem
