Flooring Design Dilemma

Lvp installation question

last year

Currently I have a laminate floor in my house (6mm of good quality rubber underlayment + 7.5mm of laminate ).
I am planning to refloor it with floating LVP now . However some installers say that installing LVP over rubber underlayment would cause the clicking system to snap out and we might lose the warranty from the company.
Is the 1.5mm of attached padding that comes in Lvp these days good enough for sound proofing . Has anyone installed LVP on top a rubber underlayment? Does it cause any problem

Typically only one layer of underlayment is allowed, if attached that is it. But check with the manufacturer but expect them to say with an additional underlayment, no warranty.

That would seem to be the answer . Is this in a condo where noise has to be very controlled ?

@kstewartau87 Yes, the sample boards, no matter the time of day, never looked to me like all the pictures look. I get screen colors vary, time of day, amount of natural light, kind of light bulb...yeah all of that. I was so disappointed when I brought the large samples home and they did not look good at all. I actually chose another color of provenza. Changed my mind at last minute due to a pit in my stomach feeling. Once installed, I was sooooooo happy I went for it despite those samples!! It's beautiful. For me: it does not show footprints bad, does not creek, feels quality under bare foot (but not like real hardwood), does not shot per hair bad. Prior to provenza I had a really dark rich laminate. It showed EVERYTHING and just the dog hair alone i was sweeping multiple times a day. Footprints anywhere light shines in and the water dribbles from my English Mastiff after drinking water were just embarrassing!! So happy I went with my gut!! Seriously. please find my pictures posted 2 years ago in this thread. There are several of my floor in different areas and one of the image that finally made me go back to my gut and install finally mine. Best wishes!

100% I'd go with engineered hardwood over Vinyl plank. I just don't understand why some people seem to feel engineered hardwood is not a good choice. I think it is fantastic and is the best choice for certain installations. I don't think engineered flooring is in any way inferior. If you like wide plank you can get that in engineered as well - up to 8-10" wide. Although a more common size is 5-6" wide. We've had engineered hardwood down in our cottage for more than 3 years. We have had no issue at all with it and I haven't noticed any fading in sunlight and we have a lot of windows. Follow the manufacturers instructions and put in good underlayment - it really can make a big difference to the comfort and sound of the floors. There are so many colours and wood species available in engineered hardwood. I know you've said you spent a long time looking at your LVP - hopefully you can find some hardwood that is similar to what you were hoping for. I think this will turn out to be a lucky accident and in the long run I hope you will be very happy with whatever you choose.

I have Coretec Hayes Oak which is a wide plank and you can purchase the treads. I like it b/c it's wide and covers the whole tread so it isn't piecy like some LVP stairs! I've had it for 4 months. No scratches on the steps which did have wood tread previously.

It's not a condo requirement and I am getting the Gaia Red series - sole (8mm) . So manufacturer says don't use additional underlayment. I currently face 2 options

Option 1 - Have the rubber underlayment but risk warranty.Also doesn't extra 6mm of rubber underlayment help with added sound proofing and heat insulation

Option 2 - If we remove the underlayment and install LVP directly on the subfloor, there would be a drop in level because the rubber underlayment is 6mm thick ( this would cause gaps at the door trims ). So the workaround would be to install quarter inch plywood and then install LVP . But this is giving an additional cost of $2.3K .

The dilemma is whether to spend 2.3k now and have the warranty or install LVP on top of rubber underlayment and risk warranty. Does installation of Lvp on top of rubber underlayment cause any issues

No offense..............but why would you risk warranty and quality of install for 2300.00 dollars ? Over five years? This is 460.00 per year to have a 20 yr floor with reasonable care.

What to do you spend on take out pizza in a year? On a daily drive through coffee?

Two layers of insulation very well may cause the click locks to break since this will basically be a floating floor.

Click flooring is a tricky thing to begin with making sure the subfloor in totally even so I agree why void the warranty at all.My advice always is do it right to begin with and in your case that meas the rubber removed and eithe live with the bigger gap under doors or install the new sub floor . IMO beats the heck out of the flooring shifting and popping out of the click

Take good pictures every step of install beginning to end. Lay a long level on that floor and snap that too. Warranties are..........very difficult to enforce in reality. Impossible, without documentation of ever step of process, should you need to enforce . All products used included.
