Preliminary advice please - choosing LVT

Hi all

I apologise in advance for the length of this post, especially as it's my first post! I'm trying to figure out the 'best' LVT solution for my parents, and so have tried to provide as much info as I can to explain my query.

I am designing and project managing a re-configuration of a 1950s chalet-style house (2 bedrooms in the roof, no bedrooms downstairs) to be able to live downstairs as my mum is not mobile enough now to go upstairs. They are wanting LVT throughout the ground floor, on existing and new areas (except bedroom). They have previously had Amtico at their old house, which after 20 years (?) is still looking perfect - it was when Amtico only had one quality option, and cost a fortune, but proved itsef to them with their lack of care over the years! Now I'm looking for a lower-budget solution to 'see them out'

The floors:
- approx 50sqm existing
- approx 50sqm new build

Existing:
- uninsulated solid slab, 20-30mm screed, old bitumen layer (old thin flexible tiles removed)

New:
- insulated slab; ufh in screed

Plan for existing:
- 2 coats bitumastic paint
- 30mm rigid cork board insulation, stuck into bitumastic layers while wet
- ply (9mm?), stuck to cork with PVA, plastic insulation fixings to hold down firm while PVA dries
- recommended installation by flooring supplier (latex; adhesive; LVTs?)

Plan for new:
- recommended installation by flooring supplier (latex; adhesive; LVTs?)

Flooring choice:
My parents are now both 80 yrs old, and don't want to spend what budget they have on Amtico, since they don't want to blow their budget on a floor that will outlast them! However, they do need something that will stay stuck down, not cause any trip hazzard to shuffling feet, and potentially cope with a wheelchair in the next few years.

Questions:
- what latex or self-levelling options are available to us for the prep, on both existing & new (if needed)?
- what thickness ply is best to use?
- what adhesives are recommended for the new areas that will have wet ufh?
- would something like Polyflor Camaro see them through 10-15 years, or are they better off going for Amtico but opting for Spacia rather than the premium stuff?
- any other more budget-friendly options than Amtico that will be 'good enough' for 10-15 years, safe for my mum who 'shuffles' a bit (can't fully lift her feet all the time), and potentially a wheelchair?

Thanks very much for your patience if you've made it this far!

Not heard of sticking cork to plywood with PVA before. Is that to insulate the floor?

I’d be looking for a .55mm wear layer LVT
my good budget one are

Moduleo transform
Luvanto
Earthwerks
Distinctive.

I’d be going with a water mix screed on the new section like

Ardex K39
F ball 300
Uzin NC150

 

Thanks all.

Yes, the cork is for insulation. The floors are really too cold at the moment and my mum spends a lot of her time sat fairly still so gets cold easily. The existing slab is dry, but the purpose of the bitumastic paint is to replace the old bitumen that was put down originally.

I'll look at the other LVT options you've each mentioned - thanks for those suggestions.

I will also look at the prep proucts and build-up you mention, Spacey & Dazlight

Thanks for the information and your exerience

 

Thanks Spacey

So your recommendation for dpm would be as above in your post:

Ardex NA screed no thicker than 6mm
Ardex 1c liquid DPM

Would the cork go in next, in your build up? The insulation is necessary I'm afraid, so I'm really looking for a way to work with this

 

You could look into using jumpax over the whole floor.

 

Very true. Had no problems with it but it don’t do well if water gets into it

 

There is a chance it could be dry. If it’s had a liquid bitumen put under the slab. There are other ways of stopping damp before the plastic sheet was invented. You really need it tested.
Jumpax will insulate the floor if its dry. If not NA and dpm

Thanks for everyone's input. I've been to 2 different neighbours who have the same construction houses, and have LVT. It is their feedback on their problems with cold floors that led to the visits, discussing their solutions, and the on-going issues with cold that the whole road still has as a regular topic of discussion (including these neighbours with Amtico) that have led to our decision to definitely insulate properly before the finished flooring goes down. I'll take on board all your advice, and keep researching

 

Will scratch and look shit in weeks

 

It's not in a shop it's for two old old people so very much doubt it he asked for any opinions I give him one

Stop being a fairy and just put on what u think then

Lvt direct to old concrete slabs is always cold, even looselay won’t insulate very well. That’s the main reason I would use jumpax. Make sure it’s dry first tho!
