I was using a board sub floor system on Saturday called fast fit. Gives you a great flat floor. Jumpax & versilay are the same I'm thinking which have a foam built in. Then you have the Forbo quick fit and the QA products version called either fast fit / heat pak / Windsor boards. This one you have to but a underlay too. Anyone use it much. It does take time putting it down I've found. How do you cut it? I use a knife. I was leaving 5-10 mm expansion gap. No skirts on which helped.
I use the jumpax quite often when there is a problem with the subfloor . Over old marley tiles etc. Its also good for over wood floors that the customer does nor want you nailing to.
Good point that as could be ripped up without doing damage to floor below. Also using over concrete the lvt will be warmer on your feet.
There are a few benefits from the system. Only downside is the expansion gap. I hade done it without on smaller jobs and have had no problems so far.
Hi daz yeah I've used QA one . Used to go there quite a bit with it being in widnes. It's a pain I think coz underlay is separate. Versalay better. IMO. The QA reps a sound fella . Cut with conc
I used the jumpax product for the first time the other week and left a 10mm expansion the room were 10 m x 6m, it seemed pretty good and solid wasn't too sure about it at first but going to use it more often,I just cut it with a concave like I would with ply.
I usually leave a gap but it's really only moisture that will make it expand, and then if you fit it correctly using dpm sheet it won't expand anyway , if all LVT is tightly fitted. No moisture can get into it. I used to fit flooring for harlequin 10-15 years ago , dance flooring .it's the same system but thicker underlay(foam) and thicker MDF panels. We use to leave a bit of a gap 5 mm and that was on 200msq rooms. Never ever expanded. Wish I'd of thought to invent the jumpax system way back then.
