Improving the Energy Efficiency of Sheet Metal Roofing
Living in a climate where temperatures are subject to larger extremes of cold or heat can result in higher costs to heat and cool a building. One way to reduce costs for heating or cooling a building is through the use of energy efficient metal roofing technologies that reduce the leakage of warm internal air in the cold months and cool internal air in the warm months. Here are some of the newer developments for improving energy efficiency in sheet metal roofing that have been installed using sheet metal fabrication methods.
Colors and Reflective Roofing Materials
Sheet metal roofing that uses reflective coatings and lighter colors can reduce a high percentage of heat loss in the summer months. Cost savings of23% to 40% have been reported by sources like the EPA, the Cool Metal Roofing Coalition, and Florida Power and Light. The reflective nature of lighter colors in addition to good ventilation systems can drastically reduce energy needs. Some of the new organic factory applied coatings that are oven baked prior to installation can further improve reflective aspects. One added benefit of using these heat reflective technologies is that a building will not contribute as large of an impact on the heat island effect.
The texture that a metal roof surface employs can assist the roofing product to be more energy efficient by reducing the conduction from the metal and the underlying surface. The textures can also further reduce heat transfer in the evening as the sheet metal roofing cools at a rapid pace slowing heat transfer in or out of the building. From an architectural viewpoint the variety of different textures and panel designs can improve the appearance of using a sheet metal roof while still maximizing energy efficiency.
Building codes and standards require that the envelope of a building meet certain requirements for energy efficiency. Internal insulation that has been installed within the envelope of the building can improve the R-Value of a ceiling. This is important because the ceiling of a building is the largest heat loss source within the envelope of a building. Based on the insulation application selected a building can also have acoustic noise reduction and vapor barrier enhancement. Joints can also receive enhanced energy efficiency through the use of sealing methods and fastening technologies to reduce conduction and decrease energy leakage.
There exist many new improvements in sheet metal roofing technologies that can drastically improve energy efficiency. With the long life of sheet metal roofs, the additional costs of using these new sheet metal fabrication technologies can be a very cost effective method to save on future energy costs and the improvements can pay dividends for decades in the future.
