It is not recommended to use underlayment for vinyl flooring.
Vinyl flooring cold temperatures.
Vinyl plank flooring is engineered to look like wood but doesn t expand and contract as oak or maple would.
There is always a risk that the cold weather is going to cause problems.
I would expect 7 10 years out of a floating vinyl floor.
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.
Vinyl floors provide you with insulation but thicker underlays can retain more heat.
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.
If you are thinking about thermal underlayment for vinyl flooring this might cause instability to the flooring.
Adhesives become brittle and then crumble below 40f some can get to 28f but then you are done.
Well vinyl flooring does get stiff and brittle in the cold.
Vinyl is not made from wood and requires a sturdy subfloor with little cushioning.
Because of its multilayered construction the planks will not expand and contract as much as a solid hardwood floor.
The cold winters will probably be too much for an adhesive to deal with.
Vinyl plank flooring and cold temperatures do not go hand in hand.
Therefore you have to be careful.
