About This Quiz

Insulating your house is one of the smartest things you can do to save money on your energy bill. But how much do you really know about green insulation? Take the Ultimate Green Insulation Quiz and find out.

Which of the following values measures a material's capability to impede heat flow?

R-value is a measure of a material's resistance to heat flow. The higher the R-value, the better the material insulates.


What percentage of energy is used to heat or cool an average home?

According to the U.S. government, heating and cooling the average house eats up about 44 percent the typical utility bill. That means most homeowners pay at least $650 a year to heat and cool their house.


Which of the following insulating materials is renewable?

Cotton is renewable. That means that farmers can grow cotton from one year to the next.


Why is cellulose a better green insulating material than fiberglass?

It takes more energy to manufacture fiberglass than cellulose, which is chiefly made from recycled materials, such as paper. Installing cellulose, however, may be a bit more pricey than installing fiberglass.


Where does most cotton insulation come from?

The main ingredients in cotton insulation are actually discarded shreds of denim.


Which of the following minerals is used in the production of fiberglass insulation?

Silica, which is found in sand, is the main component of all glass products, including fiberglass insulation.


Where does polystyrene come from?

Polystyrene, which can be made into a variety of products such as dishes and cups, is a form of plastic. Plastic is made from oil.


Which of the following reduces the R-value of fiberglass insulation over time?

Moisture of any type will reduce the R-value of fiberglass insulation because it weighs the insulation down, causing gaps or bare spots to form.


Which of the following materials is used to bond wool fibers together?

To fashion wool insulation batts, the wool is mechanically bonded with polyester strands.


What is the minimum recommended R-value for attic fiberglass insulation?

While some manufacturers may recommend different R-value minimums for fiberglass attic insulation, most agree the R-value should be in the high 20s to low 30s.


Which of the following materials is the chief ingredient of cellulose insulation?

About 75 percent of cellulose insulation comes from recycled paper.


How is cellulose insulation applied?

Cellulose insulation is sprayed into wall and ceiling cavities and attic surfaces.


Which is a type of polystyrene insulation?

Beadboard is a form of expanded polystyrene insulation.


Slag from iron-ore blast furnaces can be turned into which type of insulation?

Mineral wool is made of strands of materials, either from rock or the slag of iron ore. By law, mineral wool needs to be made of at least 70 percent recycled material.


Which best describes "block insulation?"

Block insulation is foam that contractors spray in large rectangular pieces.


What does BTU stand for?

BTU, or British thermal unit, is the amount of heat required to raise a pound of water 1 degree.


Of the following, which best describes the ability to transfer heat?

Conductivity is the ability of a material to transfer heat, sound or electricity. Copper is a good conductor.


Which of the following best describes insulation used for temperatures between -100 degrees Fahrenheit (-73.3 degrees Celsius) to -459 degrees Fahrenheit (-272.7 degrees Celsius)?

Cryogenic insulating materials are used in the transportation and storage of various low-temperature materials. The space, food, energy, medical and transportation industries regularly use cryogenic insulators.


What does the C-value of a particular piece of insulation depend upon?

C-value is short for thermal conductance and relies on the thickness of a material.


How much recycled material is in fiberglass insulation?

The U.S. government requires that 20 percent of fiberglass insulation come from recycled materials such as sand and glass.
