How to Identify Floor Tiles & Sheet Flooring That May Contain Asbestos:

This article explains how to identify floor tiles that are likely to contain asbestos, by making a simple visual inspection, noting the probable age of the building and age of its materials, and similar clues.

This document assists building buyers, owners or inspectors who need to identify asbestos materials (or probable-asbestos) in buildings by visual inspection. .

How to Identify Asbestos Floor Tiles & Sheet Coverings - Asbestos Suspect Floor Tiles & Sheet Flooring

Vinyl asbestos flooring 1974 (C) Daniel FriedmanWe provide photographs and descriptive text of asbestos insulation and other asbestos-containing products to permit identification of definite, probable, or possible asbestos materials in buildings.

Asbestos is safe and legal to remain in homes or public buildings as long as the asbestos materials are in good condition and the asbestos can not be released into the air.

Article series contents

Armstrong asbestos floor tile under the microscope (C) Daniel FriedmanWhile an expert lab test using polarized light microscopy may be needed to identify the specific type of asbestos fiber, or to identify the presence of asbestos in air or dust samples, many asbestos-containing building products not only are obvious and easy to recognize, but since there were not other look-alike products that were not asbestos, a visual identification of this material can be virtually a certainty in many cases.

Our photograph at left shows asbestos fibers and asbestos filler fragments from an Armstrong vinyl asbestos floor tile examined in our forensic laboratory.

The asbestos floor tile identification articles in this series illustrate that with the combination of design appearance and an idea of floor tile age, many asbestos-containing floor tiles or sheet flooring products can be reliably identified even before confirmation by a test by a certified asbestos testing laboratory.

On occasion, the original flooring packaging or installation literature may be available for a given home: often an extra box of floor tiles was kept for future repairs.

The vinyl-asbestos floor tile package label information, combined with a simple comparison of tiles in the package with tiles installed in the building may be sound confirmation of asbestos-containing materials.

See Vinyl Asbestos Floor Tile Packaging. Historical information about the dates of flooring installation may also be sufficient to rule in or out the possibility that flooring in a building contains asbestos.

Asphalt asbestos floor tiles as an asbestos fiber source in buildings

Asphalt asbestos floor tiles were popular in the U.S. from 1920 into the 1960's. Asphalt-asbestos floor tiles were produced at first in dark colors using a heavy asphalt binder combined with a very high percentage of asbestos filler fibers. It would be uncommon to find these floors still in use today, but if you encounter black or very dark asphalt floor tiles they are probably very high in asbestos fibers.

Source of High Levels of Asbestos in Asphalt Floor Tiles:

Asphalt-asbestos floor tiles were produced at first in dark colors using a heavy asphalt binder combined with a very high percentage of asbestos filler fibers. It would be uncommon to find these floors still in use today, but if you encounter black or very dark asphalt floor tiles they are probably very high in asbestos fibers.

Black_White_Floor_TilesDepending on the particular mixture of asphalt, gilsonite, asbestos, limestone, and pigment used, these floor tiles could contain as much as 70% asbestos by weight. One reason that so much asbestos was used in flooring tiles was simply the wish to find an application for asbestos waste product from asbestos mining operations.

The black and white floor tiles at left also may be vinyl not asphalt based since white tiles appear to have been laid at the same time as the black units. This home was constructed in the 1950's.

Since white resilient floor tiles would have been unusual to find before 1952-1955, we guess that the age of the floor may be consistent with that of the home in this photo.

While the asbestos fibers are mixed with a hard binder and the floor tiles are certainly not friable, we have read accounts of airborne levels of asbestos fibers being traced to the presence asphalt-asbestos floor tiles in areas either subjected to high volume foot traffic or to abrasive floor cleaning or maintenance procedures (like using steel wool pad floor buffing machines in a school corridor), or during demolition of this material.

Older nine-inch "thicker" vinyl or asphalt-based floor tiles, many more recent 12-inch floor tiles (1960 - 1980), and some more recent sheet linoleum as well as the mastic used to bed or glue down older flooring materials are likely to contain asbestos fibers and should not be disturbed by grinding, sanding, or demolition without taking the appropriate precautions.

We discuss the history and manufacture of asphalt-asbestos floor tiles in our Age of House articles
at Flooring Materials.

We discuss the inspection, diagnosis, and repair of various flooring products
at FLOOR TYPES & DEFECTS.

At CERAMIC TILE, ASBESTOS in? we address the question of whether or not other forms of flooring such as ceramic tile contain an asbestos hazard.

How to Identify Asphalt-Asbestos or Vinyl-Asbestos Floor Tiles as a potential asbestos fiber source in buildings

Armstrong-like Excelon (C) Daniel FriedmanAsphalt-based asbestos floor tiles and plastic or vinyl-based asbestos flooring were popular in the U.S. in the 1940's - 1970's and were produced by some manufacturers (Armstrong) as late as 1980. Some asbestos-containing flooring products were manufactured (we estimate) as early as the late 1920's.

Photo at left from a 1950's home shows Armstrong Excelon-type VAT, courtesy of reader Kim who adds that asbestos testing indicated that the white floor tiles contained 7% and the black contained 5% asbestos. We suspect the actual asbestos levels are higher in these tiles because both fibers and fine asbestos filler particles were often used.

If the flooring is being demolished, sanded, buffed with steel-wool floor polishers, or subject to heavy traffic, it might be a source of unacceptable asbestos particle release, as we discussed above at asphalt asbestos floor tiles as an asbestos source.

Armstrong was by no means the only company producing asbestos-containing floor tiles, though the company may have been the largest producer. Armstrong® produced the Excelon Tile™ series beginning with a plastic asbestos floor tile series in 1954, referring to the product as vinyl plastic asbestos floor tiles beginning in 1955, and vinyl asbestos tiles from 1957 to 1980. Resilient sheet flooring containing asbestos was also produced, finding wide use as early as 1968. The Solarian flooring brand appeared in 1977.

Not all old floor tiles or sheet flooring contain asbestos

Adding to modern confusion about which vinyl floor tiles from the 1950's to 1980's do or do not contain asbestos, some lines such as the Excelon Supreme (ca 1977) did not contain asbestos. And some six-inch asphalt based or floor tiles tested by a reader were reported to be asbestos free even though their pattern matched other 9x9 asbestos-containing floor tiles in the Armstrong line. That's right 6" x 6" - though that floor tile size was rare.

Who produced vinyl or asphalt asbestos flooring?

Vinyl asbestos floor tiles were produced by a number of manufacturers, and the decorative tile patterns were varied, often annually as styles and tastes changed. It is possible to make a tentative identification of floor tiles based on the individual tile pattern, color, and thickness.

Guides for identifying specifc floor products that do or do not contain asbestos

On occasion, the original flooring packaging or installation literature may be available for a given home: often an extra box of floor tiles was kept for future repairs. The vinyl-asbestos floor tile package label information, combined with a simple comparison of tiles in the package with tiles installed in the building may be sound confirmation of asbestos-containing materials.

Vinyl Asbestos Floor Tile Thickness and Dimensions: 9x9 inch and 12x12 inch flooring

The Wards vinyl asbestos floor tiles shown just below are nominally 1/16 gauge (4mm) in thickness 9" x 9" square.

Armstrong vinyl asbestos 9" x 9" floor tiles may also have been produced in three thicknesses, depending on the cost and durability desired by the consumer: 1/16", 3/32", and 1/8" thickness. Our 9" x9" lab sample of Armstrong vinyl asbestos floor tile was measured at 3/32" (about 2mm) thick.

Asbestos containing vinyl asbestos floor tilesArmstrong also made 12" x 12" vinyl asbestos floor tiles beginning in 1960. By 1972 most Armstrong vinyl asbestos floor tiles were sold in the 12" x 12" dimension. From 1973 to 1980 all Armstrong Excelon vinyl asbestos floor tiles were sold in 12" x 12" size.

We discuss the history of vinyl-asbestos floor tiles in our Age of House articles at Flooring Materials. We discuss the inspection and diagnosis of various flooring defects, including vinyl asbestos tiles, at FLOOR TYPES & DEFECTS.

According to Rosato, even when vinyl or other synthetic organic resins were used as the binder to produce light colored floor tiles, asbestos fibers continued to be the main ingredient in these floor tile products, and may be present at levels as much as 70% by weight.

  • General list of asbestos-containing products produced by the Flintkote Company: #229 Antisweat compound, Asbestos Cement Board, Pipe, Sheets, Felt, Joint cement, Asbestos-containing ceiling tiles, Fibrex Cement, Floor Tiles, GF-8 Floor Tile Cement, Joint compound (used on drywall or plasterboard), Plastic cement, Rexalt roof coating, other roof coatings & products, Thermalkote insulating coating, Asbestos tiles, Asbestos-containing "weld-on" cement.
  • Asbestos-cement shingles used as building siding, including wood-trained surface textures. Quoting:
    • The introduction of asbestos-cement shingles for siding, in authentic designs duplicating the textured effects of fine wood shingles, marked a forward step in the trend towards beauty, permanence and economy in modern American home building, Flintkote Asbestos Siding Shingles give pleasing permanence, plus fire protection and freedom from costly and peri- odic painting expense.
    • Flintkote Woodgrain Asbestos Sidings, textured like hand-split cedar, are available in architecturally-correct designs, with staggered, straight, or wavy lines that give distinctive shadow effects. Flintkote Straight Edge Asbes- tos Siding, with a smooth surface and attractive white finish, is another type having popular appeal. Pleasing wall effects can be obtained by combining two types on one house or by using Asbestos Sidings for part of the sidewall in combination with other materials. All Flintkote Asbestos Siding Shingles are manufactured in relatively large units for greater economy in application.
    • Flintkote Asbestos Sidings are the modern durable sidewall material for new homes or old. On present homes they can be applied right over old siding at a cost but slightly higher than a good paint job. The majority of Flint- kote Asbestos Siding Shingles are available in the Sealkote type, especially treated to resist moisture.

    • Asbestos shingles, ... possibly also containing asbestos: built-up roofing, rock wool home insulation,
    • Asbestos sidings, ... possibly also containing asbestos: hardboard
    • Asphalt sidings, ... possibly also containing asbestos: roll roofings, Therm-O-Seal felt
    • and ... possibly also containing asbestos: Asphalt paints & plastics
    • Asphalt-brick type siding: For the home owner who desires the substantial pearance of hand-made brick without its cost, Flintkote Asphalt Brick-Type and Textured Thikbrik Sidings are an ideal material. These durable asphalt sidings pos- sess all the high styling, beautiful coloring, structural advantages and fire resistance of Flintkote Asphalt Shingles. They are economically applied on new homes or old, never require paint or stain to preserve their life, and cost little more than a good paint job.
    • Shake Siding: Each exposed edge of Flintkote Woodgrain Shake Siding is unevenly trimmed across the bottom to re- capture the pleasing irregularity and rugged character of random width siding shingles used in early Colonial times. Waterproof, fire-proof, and requiring no paint or stain to preserve their life, these Flintkote Asbesto* Cement Shake Sidings are becoming increasingly popu- lar, for entire sidewalls or in combination with other Flintkote Asbestos Sidings, on either new homes or old. They cannot rust, rot, corrode or burn.
    • Straight Edge Siding: [excerpting from text partly lost] ... like all Flintkote Asbestos-Cement Sidings,...
    • Waveline Siding: For beautiful texture and distinctive charm, it is diffi- cult to surpass these Flintkole Woodgrain Waveliw Asbestos Siding Shingles.

Asphalt asbestos and vinyl-asbestos floor tiles were produced in 9" x 9", 12" x 12", and even 18" x 18" as well as in decorative strips, and in thicknesses of 1/16", 3/32", and 1/8", also in 0.08 gauge. Some sheet flooring or resilient flooring also contained asbestos, as did floor tile mastics.

This photo guide to asphalt asbestos & vinyl asbestos floor tiles for each year shows at least one color photo of each floor tile style or pattern in an example color. A list below each group of photos includes the names of and links to additional photos for other colors of these styles.

Asbestos is safe and legal to remain in homes or public buildings as long as the asbestos materials are in good condition and the asbestos can not be released into the air.

To identify a particular asphalt-asbestos or vinyl-asbestos floor tile pattern & color, start in the image group most likely to be the same age as your building.

If you don't find your floor tile or sheet flooring by looking forward from that that year, you should also look backwards in the earlier years as your specific flooring pattern & color may have first appeared in an earlier year. For other tile brands than Armstrong, see the brand name floor tile links included in this list.

If you can identify your floor tile collection name or model number, or if you recognize it in the extensive library of flooring color and pattern photographs provided in these pages, laboratory testing of the sample to screen the flooring for asbestos may be unnecessary.

Guide to Asbestsos-Containing Floor Tile Identification Photographs & Articles

The Vinyl Asbestos Floor Tile (and asphalt asbestos and sheet flooring asbestos) photo catalog became so huge that the file was slow to load and unwieldy - so we broke the catalog into segments by year range. Scan through our images of asphalt asbestos or vinyl asbestos flooring, both tiles and sheet flooring) using the links below by starting at the earliest year that might pertain to your building or to when you think the flooring was installed. Because many floor tile patterns were produced over many years there is of course overlap among these year ranges.

Many of the colors and patterns of asphalt-asbestos or vinyl-asbestos floor tiles were manufactured over many years and may appear in more than one of the floor tile photo collections listed by date range here.

For each year we list the names of the tile patterns sold during that year, we include representative color images of the floor tiles, and throughout the entire floor tile pattern & color history series we include each floor tile color & pattern of the floor tile in the first year that it appeared , and we include representative colors and patterns in other years.

Examples of floor tile packaging, labeling, and other information can be found throughout the flooring photo collections listed here.
