What are some Different Insulation Materials?
Early insulation materials consisted of grass, leaves, straw, mud, or even old clothing and newspapers. Any form of insulation was fine, and homeowners took advantage of whatever might be readily available in order to plug a hole, fill a crack, or prevent a cold breeze from whistling through the bedroom. Functionality was of far greater importance than aesthetics, efficiency, or energy conservation. In the present, however, we are offered a plethora of insulation materials. Some are well tested and traditional, and some are the products of advanced technology. Surprisingly though, some of the earliest insulation materials are now back in vogue. Often, they provide very good results. Most insulation is rated with an “R-factor.” This numeric value signifies the thermal resistance of a given insulation material. In other words, the higher the “R-factor,” the more effective the insulating material will be in terms of holding in heat. For example, a structure built solely of concrete will u
