What are the 4 types of insulation?
There are several different types of insulation, including the four most common listed below:
- Loose-Fill & Blown-In Insulation.
- Batt & Roll Insulation.
- Reflective Insulation & Radiant Barriers.
- Spray Foam & Foam-In-Place Insulation.
What are the 3 types of insulation?
The most common types of materials used for loose-fill insulation include cellulose, fiberglass, and mineral (rock or slag) wool.
Is sheathing the same as insulation?
Rigid foam sheathing is a form of insulation — continuous insulation, to be exact — that’s applied to the exterior of the building. Continuous rigid insulation is a construction solution that provides a thermally efficient building enclosure.
What kind of insulation is there?

What does asbestos insulation look like?
Vermiculite-asbestos insulation resembles rocky gravel. It is installed by pouring it into the desired location. Insulators also refer to it as “loose-fill” and “blown-in” insulation. Colors to look out for in these pebbles are grayish, brown, or silvery gold.
How many different types of insulation are there?
There are four general categories of insulation: Loose-fill/blown. Fiberglass batt. Rigid foam board.
How can you tell the difference between asbestos and fiberglass insulation?
Difference In Properties
Asbestos has a higher heat resistance and tensile strength properties when compared to fiberglass. Fiberglass is more temperature resistant than polyamide and cotton, but it isn’t comparable to asbestos in this regard.
How can you tell if insulation is vermiculite?
Identifying Insulation That is Made From Vermiculite
Vermiculite insulation is a pebble-like, pour-in product and is usually gray-brown or silver-gold in color.
What color was asbestos insulation?
Wall and attic asbestos insulations typically appear white and blue-grey. Asbestos pipe insulation is usually used as a wrap or sprayed. Wraps tend to look like corrugated paper; however, they can be difficult to spot because they have been painted over or concealed in some other way.
What type of insulation was used in the 1940s?
fiberglass insulation
When researcher Dale Kleist attempted to create a vacuum seal between two glass blocks, an accidental stream of high-pressured air turned some of the glass into thin fibers. These fibers became the base of fiberglass insulation, which became popular in the 1940s.
What type of insulation was used in 1960?
While fiberglass and cellulose rose to popularity some years apart from each other, they were the mainstay of insulation during the 1960s and onward (thanks to the fall of asbestos).
How can you tell if vermiculite insulation has asbestos?
How can I tell if my vermiculite insulation contains asbestos? The majority of all vermiculite insulation pro- duced before 1990 used contaminated vermicu- lite from Libby. Asbestos fibers in vermiculite are too small to be seen by the naked eye. Only a trained technician using a microscope can see asbestos fibers.
Should vermiculite insulation be removed?
The EPA recommends that vermiculite insulation be left undisturbed. Airborne asbestos fibers present a health risk through inhalation, so the first step is to not disturb the material, which could release fibers into the air. If you disturb the insulation, you may inhale some asbestos fibers.
When did they stop using vermiculite insulation?
1990
The vermiculite from Libby is part of the longest man-made environmental disaster in American history. It was mined there for more than 50 years, ending in 1990. The insulation, which was known by the brand name Zonolite, is most often found in residential attics.
