Ya, you won't find it in commodity construction, but just in case anyone is looking for real linoleum a currently available brand is 'Marmoleum'. It's nice stuff, I've used it on two projects but it's not every client's favorite. By the time a client is looking at sheet flooring it's usually due to cost pressure, and the client ends up going with a vinyl product.

I thought I had notes on a second brand that was more commercially oriented (maybe started with an 'R'?) but I can't remember the name at the moment.

Here you go. Tarkett -- linoleum is well hidden, under the "commercial" branch of their website only:

Thanks! I was thinking of 'Roppe' which is the not the right brand at all.

Marmoleum is a common floor replacement in the Eichlers throughout the Bay Area. It's a very nice product, and looks just right to me.

Linoleum is very eco, but highly flammable.

I'm not sure what the criteria for "highly" flammable is, I'm sure it's flammable but I've never managed to ignite it with either a blowtorch (singeing the Hessian backing on the edges of freshly cut lino) or a laser cutter (both when cutting and engraving).

It's also a good material for print making
