What are the different insulating materials?
People isolate their living rooms since the beginning of time. It didn't matter if the residence was cave, cottage, pioneering cabin or modern home, the urge for comfort was paramount. We want to stay warm in winter and in the summer cool.
timely insulation materials consisted of grass, leaves, straw, mud or even old clothing and newspapers. Any form of isolation was fine and homeowners used everything that could be easily accessible to engage the hole, fill the crack or prevent whistling in the bedroom. The function was much more important than aesthetics, efficiency or energy saving.
At present, however, it offers us a number of insulating materials. Some are well tested and traditional and some are advanced technologies. Surprisingly, however, some of the first insulation materials are now back in fashion. They often provide very good results.
Most insulation is evaluated by R. This numerical value means thermal resistance of the insulation materialin other words, the higher the R value, the more efficient the insulating material will be in terms of heat possession. For example, a structure built exclusively from concrete will usually have the designation R-1.
The most common insulation materials that are currently used are made of glass fibers. This form of insulation is usually purchased in Batts or Rolls and consists of molten glass is rotated into very fine fibers and connects together. The glass fiber insulation value is highly dependent on its thickness. For example, four inches (10 cm) of glass fiber insulation can provide the R-15. Glass fiber insulation with high density, if 12 inches thick (30 cm), reaches almost R-40.
Another of the more popular insulation materials is polyurethane foam. This foam rapidly expands and hardens after it has been sprayed into an empty cavity. When foam sets and heals, it can reachmove the factor almost R-6.5 to the inch (2.5 cm). Further foam insulation is available, some are based on cement, but are not as effective as a variety of polyurethane.
One of the most interesting and environmentally friendly insulating materials is pumped from the beginning of the twentieth century. There is a growing number of houses that use straw packages as primary insulation. The packages are stacked on a raised base and covered with wire mesh. The net is covered with plaster, stucco or concrete. The straw is also compressed under heat and high pressure to form pre -produced insulation panels.
In the age of recycling, cellulose isolation is also a viable option. In fact, this type of insulation consists of discarded newspapers and cardboard. The paper is treated with jokes of various chemicals to be resistant to flame and insects, and usually injected into the open walls by wet spraying technique. They are also recycled and used as a denim and other cotton fibers.
with a keyword to zapamInsulation is "efficiency". Each degree of heat maintained inside is projected directly into energy savings, not to mention other dollars in the bank account.
