Q. I am a homeowner, and I found some strange white fibers in the walls during a renovation. Is it asbestos?What does asbestos look like?
A : Asbestos has long had a repute as a highly toxic substance that lingers in older homes and buildings . But what is asbestos ? Asbestos is a group of of course occurring minerals that are resistant to heat energy , fire , and electricity . Because of their lastingness , they were once widely used in consumer products , from oven mitts to build insularity . However , in the 1970s , it was key that vulnerability to asbestos can cause serious malignant neoplastic disease and other diseases such as mesothelioma and asbestosis .
While asbestos is now heavily regulated in the U.S. , it ’s still possible tofind asbestos in former homesand buildings . There are three types of asbestos that are commonly found in residential or commercial properties : crocidolite , amosite , and chrysotile . Homeowners with dimension built ten ago may be wondering , what does asbestos take care like ? Or in this casing specifically , what does asbestos insulation depend like ? In brusk , it is grim , brownish , or white in coloration , and it often crumbles pronto .
It ’s important to understand how to identify asbestos and what to do if it is discovered in a home . Here ’s what homeowner ask to acknowledge .

Chrysotile asbestos is white in color and has a layered structure and curly fibers.
The vast majority of asbestos in buildings is chrysotile . This kind of asbestos is commonly found in roof , cap , and wall of buildings . Much of the asbestos found in floor tiles is also chrysotile . It has also been used in cable car part such as brake lining , gaskets and steam boiler sealskin , and as insulation for pipes , ducts , and gizmo . There are two main families of asbestos : serpentine and amphibole . Chrysotile falls under the class of snakelike asbestos , which is characterized by a curly , superimposed structure . Its flexible but durable properties are some of the reasons for chrysotile ’s popularity , as well as the fact that it is by nature resistant to heat and fire .
Amosite asbestos is brown in color and has a higher risk of causing cancer than chrysotile.
Amosite is the second most commonly used asbestos in the U.S. and pose a bang-up endangerment of cancer than chrysotile . dark-brown in colour , this form of asbestos was frequently used in cement sheets and pipage insulation , as well as insulation plank , cap tile , and thermal insulation product . It is an amphibole asbestos , meaning it is composed of delicate , needle - alike strands that can easily become airborne when touched . While it only accounts for about 5 pct of asbestos in buildings , amosite is considered to be one of the most hazardous varieties .
Crocidolite asbestos is blue in color and has thin fibers that can lodge in lung tissue.
harmonize toPenn Medicine , crocidolite is the most hazardous of all types of asbestos . Like amosite , it is an amphibole asbestos . Because it is extremely fine , its tiny gamey fibers are particularly easy to inhale . luckily , it is relatively uncommon compared with other asbestos types because it is less heat - immune . When it was used , it was usually found in battery casings , nebulizer - on coating , roof tiles , pipework detachment , plastics , and cement product . Its fibers can be identified by their down color .
Other types of asbestos include anthophyllite, tremolite, and actinolite, though their use in manufacturing was rare.
Anthophyllite , tremolite , and actinolite are all amphibole diverseness of asbestos with a precipitous , straight contour . These have been regain as contaminant in insulation and other building textile . Trace sum of tremolite in especial have also been found in ornamental production . On the whole , these type of asbestos are relatively rarified and are turn over noncommercial .
Asbestos is commonly found in insulation, floor tiles, textured walls and ceilings, and siding that was installed prior to 1989.
Before it was discovered that asbestos can be risky and potentially fatal when inspire , it was normally used in building material . So where is asbestos found ? As a result of its durability and electric resistance to heat , it has been used in flooring , detachment , roof tiles , siding , cementum mainsheet , roofing , and textured cap coatings . In 1989 , theEnvironmental Protection Agency ( EPA)placed a partial banning on the function of asbestos in edifice materials . For this understanding , it ’s most rough-cut to rule asbestos in houses work up prior or 1989 . agree to Jordan Thomas , a aged environmental adviser atIndoor Science , “ Generally any home built before the 1980s may have at least one asbestos - incorporate material . While uncommon , it is still possible to find asbestos - contain materials in young construction . ” Although there are some way to place asbestos in the home , it ’s more often than not a good idea to have a professional complete any examination and take attention of the removal if asbestos is positively identified .
Friable asbestos crumbles easily and falls apart under slight pressure.
When identify asbestos , it ’s possible to evaluate how well it break down to determine whether it is friable or non - crumbly . crumbly asbestos - contain materials ( ACMs ) , which tumble more easily than non - friable types , are now regularize due to their dismissal of asbestos and associated risks . However , they can still be discover today , as they were on a regular basis added to fabric prior to regulation .
Friable asbestos is often find in product like caloric insulation for tube , insulation for H2O heaters , joint compounds , roof roofing tile , plasters , and wallboards . Since they can be crumbled , pulverize , or trim back to pulverize by hand pressure , they personate a great risk of exposure to those reveal .
It ’s also important to note that non - crumbly ACMs can become friable if broken down or submit to sure conditions .

Non-friable asbestos does not crumble easily as a friable type does.
Non - friable ACMs , as contradict to a crumbly case , are quite hard to crumble . It ’s important to take down these dispute , as non - friable ACMs are still commonly find out in yield . For example , asbestos tiles and asbestos sidetrack are unremarkably non - friable . For those wondering , “ What does asbestos tile face like?”asbestos floor tilescommonly have an oily appearance and are typically adhere to the ground with a thick pitch-dark material called black mastic .
Because non - friable ACMs have a bonding agentive role that contains asbestos , there is a much lower danger of releasing these toxic minerals and posing a danger to humankind . However , they still remain a threat — especially if they end up getting crushed or broken , such as during a remodeling project .
Asbestos fibers are light and small, so they can float in the air for days.
While asbestos has some distinguishable feature , an depth psychology of its appearance often requires the aid of a microscope , which can show its color and shape . This is because asbestos can violate down into such small particles that its fibers ca n’t be witness by the nude center . Asbestos is only visible if it is in groups or thumping ; otherwise , the individual fibers are too small to see without a microscope .
Because asbestos fiber are often microscopic , they can be airborne for days without being detected . This means they are easily breathe in into a someone ’s lungs , causing serious health proceeds . Any asbestos exposure is dangerous , but harmonise to theMinnesota Department of Health , the amount of asbestos in the strain and the duration of pic sentence can affect the likelihood of wellness issues developing . If homeowners are finger asbestos symptoms such as chest pain or abruptness of breath , they will want to consult with a doctor as before long as possible .
As a raw fiber mineral, asbestos is usually soft to the touch, unless it has been used in making a compound material.
Asbestos , in its raw form , is typically a soft mineral . Chrysotile in particular , which accounted for about 98 percent of worldwide asbestos output in 1988 , is made up of soft , pliant fibers . For this reason , it has been used in textile and even clothing . Chrysotile mineral run to do less damage to body tissue than other types of asbestos ; however , they ’re still extremely dangerous and it is recommended that they be avoided .
Testing for asbestos is a job best left to professionals.
asunder from finding visual grounds of asbestos , there are several casing in which asbestos examination may be necessary . “ understanding for asbestos sampling are usually triggered by home renovations , damage building materials due to flooding or disaster , and during a tangible acres dealings , ” says Thomas . While the potential presence of this hazardous subject matter can be alarming , there are steps homeowners can take to secure safety and derogate asbestos exposure . If a householder suspects the presence of asbestos in insulation , popcorn ceilings , or other common locations , they ’ll want to call a professional for asbestos test immediately . There are tidy sum of DIY asbestos test kits on the market , but it ’s a good idea to have a professional make this evaluation as they know how to try out for asbestos without expel the fibre into the air . Once the areas of concern are good evaluated , they ’ll advocate an action plan to either slay or repair the asbestos .
A professional can also advise on the best path forward to repair or remove asbestos from the home.
Asbestos repair is typically the preferred method for handling asbestos since it involves the least amount of risk . According to Thomas , “ Asbestos - containing materials pose minimal wellness hazard if the material is entire and not disturb . ” A professional can acquit a mending either through encapsulation ( coating with a sealer to prevent fibers from becoming airborne ) or enclosure ( get across with airtight textile to prevent the dismission of fibre ) . For example , a common way to carry on with popcorn ceiling asbestos is to coat it with sealant since removal would require breaking up the material , potentially releasing fibers into the line .
Asbestos removalis view a last resort for most homeowners who find asbestos . The process of removing asbestos often causes fibre to become airborne within the home , which can put serious wellness jeopardy . However , thebest asbestos remotion companiesfollow strict road map to ensure the safe remotion of asbestos , including sealing off the area before disposing of it in a plastered dumpster or at an sanction website .
Throughout the process , professionals wear gear and respirators that are specially design to protect against tiny asbestos vulcanized fiber . to boot , these authorized individuals will handle cleanup spot and re - evaluate the space before homeowners return . Professionalasbestos removal costsabout $ 1,123 to $ 2,872 .

While asbestos hiatus price are not insignificant , it ’s important to note that DIY remotion can be extremely grievous , and there may even be sound requirements for how asbestos is disposed of depending on the country . Homeowners who discover asbestos in their homes will want to consult a licensed asbestos abatement professional to call the yield . However , knowing how to visually discover asbestos is a expert first step in making a home safer to live in .
