A Brief History Of Insulation - Look How Far We've Come
The Ancient Egyptians used it. Therefore did the Old Romans. In the 1800's, a guy wrote about it, sort of. By the Great Depression, there is a model baju batik demand for this. In the mid 1970's, medical research told us we were carrying it out wrong. Today, 21st century builders need to "live green" to earn green. And the future seems brighter (and more energy conserving than ever.) We've used cork, asbestos, glass, plastic, foam and actually mud to accomplish it. Yes, when you consider the history of insulation, in every its myriad forms, we are able to see just how far we've come.
The Ancient Egyptians used insulation to keep their desert homes and structures cool, and their linen clothes warmer in the cooler winter season. They added papyrus linings to their loincloths and skirts to maintain warm in winter. They constructed their homes of heavy brick, designed to help keep out the sun's scorching temperature in summer.
The Old Greeks knew about asbestos, actually they named it. They used it to outfit their imported slaves, as well as for the wicks of their eternal flames, napkins and the funeral outfit of kings. The material's flame-resistant properties gave it a bit of a mystical charm to the Greeks. That they had a common name for this, too - crysotile - which means "gold fabric." The Greeks were the first ever to continue record as noting that asbestos caused a "lung sickness" in the slaves who caused it and wore it. The Greeks also knew how exactly to insulae their homes, using cavity walls. The air trapped in between the inner and outer walls would act to help keep out the colder or hotter atmosphere, depending on the season.
Always on the look-out for another best thing, the Ancient Romans also dressed their slaves in asbestos cloth. They made tablecloths and napkins for restaurants and banquets out of asbestos fabric, throwing it in to the fire between diners or courses to clean it of crumbs. The Romans had been perhaps the ancient world's most noted engineers, and they knew plenty of to build cavity walled structures, too. They discovered to insulate their heated water pipes with cork from Spain and Portugal so that they could be placed under floors without fear of the flooring.
The Vikings and additional northern Europeans discovered to insulate their homes with mud chinking, plastering it in the cracks between your logs or hewn boards of the buildings walls.. When mixed with equine or cattle dung and straw, the mud was referred to as daub, and was considered a stronger, better building material over plain old mud. They created clothes out of solid sheep's wool, and could have even used fabric to line the interior walls of their homes.
Cloth came to be trusted in the centre Ages among the wealthy as stone once again arrived to fashion for home building. These imposing stone structures tended to be drafty, damp and cold. Huge ornately embroidered or woven tapestries would be hung on interior wall space, partly to filter the drafts and partly to soak up the dampness.
