When Was Fiberglass Insulation Invented?

The Basic Definition of Fiberglass and Insulation

Fiberglass is a type of reinforced plastic made with woven glass fibers. It is durable, flexible, and lightweight, which makes it a popular material for various applications, including construction, automobile manufacturing, and aerospace. The strength of fiberglass comes from the glass fibers that are woven together to produce a solid and resilient material.

Insulation, on the other hand, is a material that helps regulate temperature by trapping heat or cold air. This is important because it helps maintain the desired indoor temperature, reduces energy consumption, and saves money on heating and cooling costs. Insulation comes in different forms, such as fiberglass batts, blown-in cellulose, spray foam, and rigid boards.
