Roof insulation refers to reducing heat loss through the roof to keep your home fairly warm. At the same time, it refers to increasing heat absorption to keep your home cool. This saves on the costs incurred in warming the home using energy consuming methods. It also means you can have a cool home in summer, without spending a dime. Before you hire someone to carry out your roof insulation for you, it helps to know which methods are used. This will give you the power of making an informed choice on the method you want. Here are some to the most effective methods used.
Wood fiber roof insulation involves the use of organic insulation boards made of wood, cane or vegetable fibers. These are mixed with binders which hold them together. Coating with asphalt increases moisture resistance of the fiber. However, you should be professionally advised on the asphalt, since some roofing materials are incompatible with it. There are available fibers without the asphalt coating.
Perlite is an inorganic material made of expanded silicaceous glass. Organic matter is mixed into the perlite and then bound together. The surface has asphalt or other proprietary coating. Where your roofing material is incompatible with asphalt, you can use the alternative. Being inorganic, the perlite has natural moisture resistance, but the organic fillings do not. That is why the extra coating is necessary.
Polystyrene is a polymer commonly used in insulating roofs. Polystyrene can be expanded using a foaming agent infused into it. It can also be extruded through heating and exposure to atmospheric elements, which enables it to form its own expanded cell structure. Polystyrene is able to expand during hot conditions and absorb heat in the process. It also contracts during the cold periods, thus releasing heat.
Cellular or foam glass is made by heating glass particles within a chemical foaming agent such as carbon. When the mixture cools, it forms a solid foam with air particles in it. This makes it very efficient as a heat absorption or heat releasing agent. It thus helps to regulate temperature well as and absorption agent. Moreover, it is strong and has fewer compatibility issues.
A gypsum board or drywall, is a panel made primarily of calcium sulfate dehydrate. It is used in the construction of walls and as a roof insulation material. It may or may not be mixed with other materials. Such materials may be paper or fiberglass. Mixing with other materials increase its insulation capabilities.
Choose the Best Insulation Method for You
You can choose the insulation method that best suits you for your home. The options include wood fiber, perlite, polystyrene, cellular glass or gypsum. Whichever method you use, find out how effective it is in regulating heat, by absorbing it and releasing it when necessary. You should also make sure you get professional advice on how compatible it is with your chosen roofing material. If it is not compatible, then corrosion may occur thus shortening the life of your roof.
