I would expect 7 10 years out of a floating vinyl floor.
Vinyl flooring cold temperatures.
Adhesives become brittle and then crumble below 40f some can get to 28f but then you are done.
Vinyl floors provide you with insulation but thicker underlays can retain more heat.
If you are thinking about thermal underlayment for vinyl flooring this might cause instability to the flooring.
It is not recommended to use underlayment for vinyl flooring.
Vinyl is not made from wood and requires a sturdy subfloor with little cushioning.
Can you offset these problems by using a thermal underlay.
Well vinyl flooring does get stiff and brittle in the cold.
Therefore you have to be careful.
There is always a risk that the cold weather is going to cause problems.
I know this cuz i ve cracked some pieces trying to install them in probably 20f weather so if you had a saggy baggy floor that moved when you walked on it i suppose there could be some risk of cracking.
The plank design is installed in a floating manner so it can move with temperature changes unlike a vinyl sheet that will become brittle and crack in extreme cold.
Amid changes in temperature and humidity all flooring materials are susceptible to expansion and contraction to some extent but engineered hardwood flooring is going to be the most dimensionally stable material you will find.
Vinyl plank flooring and cold temperatures do not go hand in hand.
Because of its multilayered construction the planks will not expand and contract as much as a solid hardwood floor.
