If you're looking at a plot of old padding inside your attic plus wondering does fiberglass have asbestos , the particular short and direct answer is simply no. Fiberglass and asbestos are two entirely different materials along with different origins, even though they often get lumped together since they served similar purposes in building for decades. It's a common point of confusion with regard to homeowners, DIYers, and anyone living within a house constructed before the eighties, mostly because each are fibrous materials used to keep high temperature where it goes.
While they will might look similar to the inexperienced eye—or at minimum behave similarly when you're seeking to squash them in to a wall—their chemical makeup plus the way they will affect your entire body are worlds apart. Let's dive directly into why people get both of these mixed upward, what actually goes into fiberglass, and why you can usually breathe a little easier (though still by way of a mask) when dealing with typically the pink fluffy things.
Why do people think fiberglass and asbestos are usually the same?
It's easy in order to see where the particular mix-up happens. In case you go back to typically the mid-20th century, asbestos was the "miracle mineral. " It was everywhere. It has been in floor tiles, roofing, pipe cover, and yes, padding. Around the same time, fiberglass started getting the go-to substitute for residential insulating material. Simply because they were both used during the exact same era of house building, they usually exist side-by-side within older structures.
Another reason for your confusion is their physical form. Both materials are made of tiny, microscopic fibers. When these types of fibers get airborne, they can end up being inhaled, which is where the health issues start. However, the way in which those fibers connect to your lungs is the reason why one a small irritant and the other a serious health hazard.
What is fiberglass made of, anyhow?
Fiberglass is precisely what it sounds like: extremely good fibers of glass. It's a man-made product. Manufacturers create it by burning down sand and recycled glass at incredibly high temps and then rotating it into thin strands, almost such as cotton candy. In order to keep the fibers together, they usually give a resin or a binding realtor, which is usually why fiberglass insulating material has that distinctive pink, yellow, or even green color.
Because it's made from glass, it doesn't rot, it's not really particularly tasty in order to pests, and it's naturally resistant to fire. It's a good incredibly efficient insulator because the countless tiny glass fibers trap pockets associated with air, slowing down the transfer associated with heat.
The darker history of asbestos
Asbestos, however, isn't man-made. It's the group of 6 naturally occurring silicate minerals that are usually mined through the earth. Long before there was industrial factories rotating glass, we had been digging asbestos out there of the floor because it had been practically indestructible. It's incredibly resistant to heat, electricity, and chemical corrosion.
The problem along with asbestos isn't the material itself whilst it's sitting still; it's what occurs in order to breaks. Asbestos fibers are "friable, " meaning these people can easily become crushed into a fine dust. These fibres are needle-like plus jagged. Once you inhale them, they obtain hooked deep straight into the lining of your lungs (the pleura) and your body can't get them out. Over decades, this leads in order to serious issues like asbestosis, lung malignancy, and mesothelioma.
Can fiberglass insulation contain asbestos?
Strictly speaking, fiberglass does not contain asbestos as an ingredient. They are distinct products manufactured by different processes. However, there is a tiny "but" here for people living in very old homes.
In some rare instances, cross-contamination could happen within a factory that will processed multiple varieties of insulation decades back, though this wasn't the norm. More commonly, you will probably find the home where asbestos insulation (like vermiculite) was installed very first, and then somebody later decided in order to blow fiberglass on top of this to save money or even enhance the R-value. In that scenario, the particular fiberglass itself doesn't have asbestos, yet it's sitting upon top of the pile of this.
If you see "batt" insulation—the big proceeds or blankets that look like quilted fabric—that's almost definitely fiberglass or mineral wool, not asbestos. Asbestos insulation in attics usually appears like small, pebble-like stones (vermiculite) or even a gray, fluffy, "wool-like" substance that appears more like unclean lint than glass.
Is fiberglass dangerous to inhale?
Just mainly because the answer to does fiberglass have asbestos is no, doesn't mean you should go ahead and do a tummy flop into a pile of this. Fiberglass is still an irritant. If you've ever handled this without gloves, a person know exactly what I'm talking about. Those tiny glass shards prick your own skin, causing that will signature "fiberglass itch" and redness.
When fiberglass fibres get into the particular air, they could annoy your throat, eyes, and lungs. You'll probably cough or feel a tingle. The big distinction is that fiberglass fibers are generally larger and more "brittle" than asbestos materials. Your body is in fact pretty good with getting rid of fiberglass; you cough it upward or it moves through your program. It doesn't typically get "stuck" for life the way asbestos does. That stated, long-term, heavy publicity without protection isn't exactly ideal for your respiratory health, so always wear your PPE.
Just how to tell the difference visually
In the event that you're doing the renovation and you're worried, here's a quick cheat page on what you're likely looking with:
- Lilac, Yellow, or White colored Fluffy Batts: This will be fiberglass. It's generally fairly modern and doesn't contain asbestos.
- Gray, Paper-like Blown-in Material: This is usually cellulose. It's made from recycled papers and given fire retardants. Generally secure, but it can be dusty.
- Pebble-like, Shiny, Silver-Brown Flakes: This is most likely vermiculite. A massive portion of vermiculite used in the US came from a mine in Libby, Montana, that was contaminated with asbestos. In the event that you see this particular, stop what you're doing and call a pro.
- White/Gray Chalky Pipe Wrap: If a person see old piping wrapped in some thing that looks such as corrugated cardboard or even dried plaster, that will is very likely asbestos.
What should you perform if you're uncertain?
If you're staring at several old, mystery insulation as well as the question does fiberglass have asbestos is still nagging at you, don't guess. It's not worth the particular peace of brain to just "hope" regarding the best.
You may buy an asbestos testing kit with most hardware shops. You take a small sample (while within the high-quality N95 or P100 mask), seal cracks in the bag, and send out it to a lab. They'll give you a certain answer for a fairly small fee. If you're planning a huge demolition, hiring an asbestos abatement professional to do a sweep of the particular house could be the wisest move you may make.
Safe handling suggestions for fiberglass
Even though we've established fiberglass isn't the "death dust" that asbestos is, you continue to need to treat it with respect. If you're going into an attic to move some around, right here is the bare minimum you need to be doing:
- Use a Mask: Not just a cheap paper mask, yet a well-fitting N95 respirator.
- Cover Your Skin: Wear long masturbator sleeves, long pants, plus gloves. Tape your sleeves to your own gloves if you're going to be reaching deep into the particular joists.
- Eye Protection: Goggles are usually better than glasses because they close off around your face. Getting glass materials in your eyes is an expertise you want to avoid.
- Shower Instantly: When you're done, wash your clothes individually through the rest of the laundry. Have a cold shower 1st to rinse the fibers off your own skin (hot water opens your pores and lets the fibers sink in deeper), then switch to warm water.
The bottom line
The anxiety surrounding asbestos is definitely totally justified—it's awful stuff. But whenever it comes to the question does fiberglass have asbestos , you can usually rest easy knowing they are 2 different animals. Fiberglass was largely the solution to the problems asbestos created. This gave us a way to insulate our homes efficiently without the fatal side effects of the particular "miracle mineral. "
Just remember that "safer" doesn't mean "completely harmless. " Deal with your insulation with a bit of caution, wear your own gear, and whenever in doubt, have it tested. Your lungs will thank you twenty years through now.
