Rubber mats/gym flooring

Hey y’all my wife and I just moved into a house that was built in the 1870s and the addition on the house is a kitchen on the main floor that has no insulation in the floor (it cantelevers out over the entrance to the basement). Anyway we are renting so I can’t make any permanent changes but I was thinking of putting down that interlocking rubber mat flooring like you see at gyms or day cares as a secondary barrier on top of the floor and it seems to me that those should help insulate quite a bit. Opinions?

Are you sure the owners won't allow you to install insulation?  Seems to me it would be cheaper than those mats and would work better.


I have a couple rentals and I've never objected to the tenants making 'improvements' to my houses.
