those are awsome, I've used them before. But you want to seal the cracks between the squares. they sell this stuff that is sort of like small tubes of superglue. you just dribble it in the cracks to seal them so water can't get down under your tiles and ruin the sub floor.

That is very good to know --- thank you! I've never used linoleum squares before and was shocked at how easy they were (after we swept and scraped and mopped all of the construction gunk off the floor, that is... )

When my current laminate flooring is up for replacement I'm going to have to take a good look at linoleum. Two things that I dislike about laminate flooring is the fact that it feels cold to my feet (and I like walking barefoot indoors), and the effort of putting it in. When I renovated my kitchen, I put in vinyl because the kitchen floor can get wet. It was a lot less effort, and feels much warmer. I wonder if linoleum is similar? Does it feel warm to the touch?

Drat --- you have to ask the hard questions. Honestly, as I read your comment, I'm not sure whether those tiles were vinyl, linoleum, or laminate --- I thought it was all the same thing. Maybe Mark will chime in here.

But I do agree with you that everyone should be barefoot in the house!

It's most probably vinyl a.k.a. PVC. In real linoleum, the color runs through the whole thickness. So to make patterns you have to cut out pieces and fit them together like a jigsaw puzzle. Linoleum is usually calendered onto a woven backing. Vinyl has a printed surface, with a usuallly white foamy substance underneath. The vinyl in my kitchen looks like huge stone tiles, and several people have mistaken it for real tiles.

The good thing about real linoleum is that it's made from renewable materials. But it's probably much more expensive than vinyl.
