Linoleum with Asbestos Backing
Traditional linoleum flooring with asbestos-containing felt or paper backing for moisture resistance.
Description
Linoleum with asbestos backing combines a traditional linseed oil-based surface with an asbestos-containing felt or paper substrate. Manufactured from the 1940s through to around 1980, this product was widely used in residential and commercial settings, particularly in kitchens, bathrooms, hallways, and utility rooms. While the linoleum surface layer itself is made from natural materials including linseed oil, wood flour, cork dust, and jute, the backing layer frequently contained chrysotile asbestos at concentrations of 30% to 60% by weight.
True linoleum is distinct from vinyl sheet flooring, although the terms are often used interchangeably by the public. Linoleum is manufactured from natural raw materials and has a characteristic linseed oil smell. The product was valued for its durability, antimicrobial properties, and sustainability long before these qualities became fashionable. However, manufacturers added asbestos to the backing layer to improve moisture resistance, dimensional stability, and fire performance.
Major linoleum manufacturers including Nairn, Armstrong, Forbo, DLW (Deutsche Linoleum Werke), and Congoleum produced asbestos-backed variants. The product was particularly popular in the United Kingdom, Germany, the Netherlands, and Scandinavia, where linoleum had a long tradition. In Germany, DLW was one of the largest linoleum producers in Europe and widely used asbestos in their backing materials.
The asbestos hazard in linoleum is identical to that in vinyl sheet flooring: the backing layer is the source of risk. When linoleum is pulled up, the backing may tear, fragment, and release asbestos fibres. Old linoleum often becomes brittle and difficult to remove in one piece, increasing the likelihood of backing damage. The adhesive used to bond the linoleum may also contain asbestos. As with other backing-related materials, the recommended approach is either to leave the linoleum undisturbed, encapsulate it with new flooring, or engage licensed professionals for removal.

How to identify
True linoleum has a distinctive linseed oil smell and is made from natural materials, unlike vinyl flooring. The backing layer is the key area to inspect: asbestos-containing backings appear as grey, tan, or off-white fibrous felt. The surface may show marbled or jaspe patterns characteristic of linoleum. The material is generally thicker and more rigid than vinyl sheet flooring. Linoleum installed before 1980 should be presumed to have asbestos backing until proven otherwise by laboratory analysis.
Health risk & friability
This material has a risk level of 2 out of 5.
It is classified as non-friable, meaning the asbestos fibers are tightly bound within the material matrix. When in good condition and left undisturbed, the risk of fiber release is low. However, cutting, drilling, sanding or breaking the material can release dangerous fibers.
What to do if you find this material
Do not attempt to pull up, scrape, or sand linoleum flooring if you suspect asbestos backing. If the linoleum is in good condition, the safest option is to leave it in place or install new flooring over it. Have a professional asbestos surveyor take a sample of the backing layer for laboratory testing. If removal is necessary, hire a licensed asbestos removal contractor who will use wet methods, containment, and HEPA filtration to prevent fibre release.
