More Fiberglass Uses

Fiberglass is used in carpets, cars, and inside homes. But did you know it is also used in.

Fiberglass Tape

A brown cardboard box with blue packing tape across the top with strands of white glass coming from under the ripped tape. There is a hand with red painted fingernails holding the end of the fiberglass strand.

Some types of tape contain fiberglass. Sometimes used as packing tape, when you open the box the strands often fray apart.

Cigarette Filters

Glass fibers are used in the filters of most commercial cigarettes. All of the little cuts down one's airways help the body absorb the nicotine.

HEPA Air Filters

It is hard to believe, but even some HEPA air filters contain glass fibers. People set up air purifiers to try and get fiberglass out of the air using a fiberglass filter. Makes perfect sense.

Roof Shingles

Some types of roof shingles contain fiberglass. The components of fiberglass shingles are glass fibers and formaldehyde resins that are combined using asphalt. The pictures show the glass fiber base after the other components were removed.


Some furnace filters are made with glass fibers in them. Sometimes called a spun glass filter.

Microscopic glass fibers are also used in some brands of toothpaste as an abrasive. It cuts into the tooth allowing the fluoride to penetrate.
