Insulation works by trapping air or other gases in a material, which then prevents heat from being conducted through that material. The most common type of insulation is made from fiberglass, but there are also insulations made from other materials such as cellulose, mineral wool, and foam. Each type of insulation has its own advantages and disadvantages, so it's important to choose the right one for your needs.
Fiberglass insulation is the most common type of insulation. It's made from glass fibers that are spun into a mat and then sandwiched between two pieces of paper or foil. Fiberglass is an effective insulator because it doesn't conduct heat well. It's also fire-resistant and relatively easy to install. However, fiberglass can be irritate your skin and respiratory system, so it's important to wear protective clothing and a mask when working with it.
Cellulose insulation is made from recycled paper products such as newspapers and magazines. It's treated with chemicals to make it fire-resistant and resistant to pests. Cellulose is less effective than fiberglass at preventing heat transfer, but it's also much cheaper. Cellulose insulation can be installed by yourself, but it's more difficult than fiberglass insulation.
Mineral wool insulation is made from rock or slag fibers. It's often used in commercial and industrial applications because it's very fire-resistant. Mineral wool is also effective at preventing heat transfer, but it's more expensive than fiberglass or cellulose insulation.
Foam insulation is made from plastic foam that's been treated with chemicals to make it fire-resistant. Foam insulation is easy to install and very effective at preventing heat transfer. However, it's also the most expensive type of insulation.
