Anyone any alternative suggestions to Marmoleum as a floor covering in an office building?

Also anyone used Marmoleum that can provide any advice?

Thanks

Natural rubber floor covering? Saw them at Ecobuild last year. Google Dalsouple.

Thanks for all the ideas.

Anyone used renewalcarpet tiles. http://www.renewalcarpettiles.com/

86% recycled nylon.

depends on the type of space you're trying to create in the office building...

we often use marmoleum, look at Forbo, infact they've just brought out a new product that is part linoleum and part cork:

Freudenberg or Nora have a great selection of rubber flooring: www.nora.com
for natural flooring, wool or plant fibres take a look at Crucial Trading: http://www.crucial-trading.com
Interface supply commercial carpet, but not too sure of their full sustainability credentials... i think they may offset their carbon.

but check the technical details for anti-static properties and appropriateness for castors if it's an office environment.

At Work for Change in Manchester (co-operatively managed workspace in a 12 year old building with green purchasing policies) we have used Marmoleum and Dalsouple - the Dalsouple has lifted in a few very heavy traffic areas (after 12 years) but you can replace one tile easily. Don't choose much of a pattern, the dirt tends to build up around the bumps on ours. The Marmoleum has been down for about five years, the darker purple area looks lovely but the lighter beige coloured tiles have become grubby looking and stained and are being replaced with a darker colour.
