What Is the History of Home Insulation?

August 7, 2015

Fred Flintstone probably had little need for home insulation – with walls made of granite and boulders. But the residents of Bedrock could have used some type of window covering to prevent heat from escaping during ancient winters or to keep their homes cool in the summer.

Home insulation has been attempted and explored throughout most of real human civilization for thousands of year, but only materialized as a commercial institution more than a century ago.

While we at Capitol Machine spend our time in the present tense with our eyes carefully focused on the future, we delight in examining the past to discover lessons learned and to understand how old methods shaped our modern commerce. What Is the History of Home Insulation?

What is the History of Home Insulation

Ancient Home Insulation Installation Contractors Used Clothing

Ancient Egyptians used asbestos to insulate their homes and for their clothing. Their Greek and Roman counterparts built cavities in their homes with two stone walls allowing internal-wall air flow, a natural insulator.

Homeowners in the Middle Ages used strips of cloth to insulate their homes. Americans also used cloth in their homes during the Great Depression.

Builders started using cavities in homes in the early 19th century in Europe and America. Rock wool insulation was built into the walls. The use of asbestos soon followed but ended in 1970s after researchers learned of the material’s health hazards.

Few homes were built with proper insulation during the early decades of the 20th century because energy costs were low. During the 1950s many homes had single-layer masonry walls and single-glass-pane windows. In the last 30 years, as energy costs have climbed, the need for adequate and proper home insulation also rose.

Many homes today use fiberglass insulation, which traps air between fibers and prevents heat transfer. This mitigates temperature fluctuations and creates a climatic barrier. Well-insulated homes significantly reduce energy costs by closing air leaks.
