Natural Linoleum

Linoleum aka Natural Linoleum

Compiled by Manina Dodd

General Info:

Linoleum was invented by Frederick Walton in Staines, England, in 1860. It remains in production as one of the few washable flooring surfaces which are made of natural ingredients. Linoleum flooring is made from solidified linseed oil, mixed with resins, ground limestone, wood flour, and cork dust. After mixing, these materials are applied to a burlap or canvas backing, and pressed between rollers in a process known as calendering. Users should not be alarmed if the newly laid linoleum gives off an oily smell, similar to fresh paint, or if it has a yellow tinge known as ‘ambering’. Both these effects are temporary. Linoleum flooring is available as sheet or tiles, for glueing down, or as rigid click-together panels having a linoleum surface on a fiberboard and cork base. Vinyl flooring is sometimes generically referred to as “linoleum,” so be sure to request “natural linoleum.”

COMPARISON TO VINYL

Natural Linoleum

Made of Natural Ingredients

Offgassing from Natural Oils

Renewable and Biodegradable

Durable and Self Healing

30-40 Year Lifespan

Color is embedded deep in the surface adding to durability.

Many more color choices available now providing greater competition with vinyl.

Vinyl Flooring

Made of Synthetic Ingredients

Offgassing from Petroleum Distillates

Production and Incineration Creates Dioxin

Lower Durability

0-20 Year Lifespan

Color sits on top and wears off faster.

Vibrant and wide range of colors and textures.

Natural Linoleum can generally be classed as nature friendly or definitely a “green” alternative to vinyl because a Life Cycle Analysis shows that it:

•uses natural raw materials that are rapidly renewable

•primary energy carriers such as mineral oil and gas are not needed in the product although they are used in the manufacturing and shipping (from Europe where its manufactured)

•it does not damage the ozone layer with toxic offgasing

•it has a long lifespan and thus reduces waste products

•it does not result in toxic waste and might be composted; there are some moves to use the incineration of it to produce power

•can be installed with low or no voc waterbased adhesives

•not sure of Fair Trade status, some discussion

1) Life Cycle Analysis (LCA) quantifies the potential environmental impact of a product system over the lifecycle

Added benefits:

•linseed oil is an inherent anti-microbial so it is useful in kitchens, bathrooms and hospitals;

•lineoleum is inherently anti-static and therefore repels dust and dirt

•it is easy to maintain with sweeping and damp mopping with a neutral soap; can be further protected by using a recommended sealer

•if the floor gets scratched, it can be repaired with buffing and a coating of sealer

•it actually increases in strength overtime

•wont melt or ignite except at extremely high temperatures

•comparable in price to high end vinyl

Caution:

•while it does not emit toxic gasses, it does emit ordor that may be irritating to acutely chemically sensitive people and children; this can be mitigated somewhat by allowing for ventilation between installation and occupancy

•installation can be tricky especially in sheet form and should be done by experienced installers; less of a problem with tiles

•care needs to be taken that sub-flooring is not prone to moisture so locations such as basements may not be appropriate if there is a potential for moisture to seep in

•its important for linoleum to “acclimate” for at least a week prior to installation
