About Metal Roof Insulation
A metal roof is typically a structure made from metal sheets or pieces. It is one of the most important and necessary elements of a building enclosure. These roofs are made from aluminum, copper or steel panels and are generally used in residential and commercial buildings to shield against harsh weather and other environmental conditions. Metal is one of the most enduring and long-lasting roof materials currently available on the market. With little maintenance and care, these roofs can last for decades.
Although metal is a simple and inexpensive material used in roofing structures, it actually has relatively poor thermal insulation qualities, so the un-insulated metal roof may leave a building structure exposed to harsh climatic conditions. Without proper insulation, the building could become extremely hot during summer season and cold during wintertime.
Insulation provides an effective barrier against temperature changes and helps to keep the heat in and the cold out. It also provides a means of reducing compression that is formed near the base of a metal roof due to variations in humidity, temperature, and other factors.
Types of Metal Roof Insulation
There are various technologies used in insulating a metal roof. Some newer technologies include spray foam insulation and thermal insulation.
In spray foam insulation, a mixture consisting of Isocyanate and resin is put into a gun and is sprayed onto concrete slabs, roof tiles, wall cavities as well as holes or openings present in the finished wall. This insulation can help to maintain a consistent temperature and humidity level within a building while helping to conserve energy and expand the life of the roof.
Similarly, thermal insulation can be done through special methods. This type of insulation provides a region in which the conduction of heat is reduced and heat radiation is reflected instead of absorbed by the building.
Metal roof insulation keeps your home and buildings warmer in the winter. Insulation, being a heat barrier, works on a simple principle; it reflects all the heat back to its original source. This means that during winter season, there is less radiant heat loss through the roof and attic, resulting in the retention of heat inside the building. Insulation in your home and building can help make your living situation more cozy and comfortable. It also helps to reduce your heating and energy costs.
It Keeps Your Homes and Buildings Cooler During Summer
During long and hot summer days, an insulated metal roof reflects the radiant heat away from your roof and attic, keeping it from gathering inside your building. During hot weather, more than 93 percent of heat is radiant. Again, insulated metal roofs keep your building cooler by slowing down the process of heat gain. Reduction in energy costs and utility bills
Insulation can help cut energy costs significantly and reduce the amount usually spent on utility bills. Studies conducted by the US Department of Energy shows that more than 40 percent of an average sized home’s energy is lost as a consequence of air infiltration through windows, doorways and even walls. However, buildings that have been insulated minimize this process and help you save on energy costs.
Help in Earning Tax Credits
In some jurisdictions of United States, a person can earn tax credits on property taxes, if the roof is constructed using energy saving insulation materials and is successfully installed by some reputable service providers. The tax ordinance further states that if the roof is installed during 2012 or you are intending to add it in 2013, then you will become eligible for an energy tax credit of $500. There are also a variety of other tax credits available for commercial buildings.
Increases Your Building’s Resale Value
Quality metal roofing insulation improves the resale value of your home as well as commercial buildings. It protects the building from physical wear and tear, making them look new and clean. It does not allow the building to depreciate but revalue it.
Provides Protection Against Moisture
Insulation safeguards the building against humidity and moisture, which provides an additional advantage by reducing the chances of growth of harmful mildew and mold inside the building. Reducing mildew growth also minimizes the chances of rotting wood or the spread of allergy-inducing mold and fungus.
Reduces Noise Pollution
In addition to controlling temperature, humidity and moisture inside the building, there is another advantage of installing insulation in your building, i.e. it also has the ability to absorb and shield against. These roofs act as a barrier to air borne sounds and thus help in reducing noise pollution. The benefits of metal roof insulation are numerous and it is apparent that opting for this type of roofing will help consumers save money while increasing their overall comfort for years to come.
