METAL ROOFS AND INSULATION: STAYING COOL WHILE SAVING ENERGY
Typically, the effectiveness of insulation versus a cool metal roof isn't an either/or question. Most building codes require some amount of insulation - quantity and R-Value being dictated by the climate where you live. Cool metal roofs, on the other hand, are specifically designed for warm and hot weather climates, where the lion's share of undesirable heat transfer is the result of UV absorption through the roof. Most building experts recommend using a combination of insulation and a reflective metal roofing system in order to optimize energy efficiency and interior comfort while minimizing solar heat gain since insulation and reflective roofs mitigate heat transfer differently. INSULATION HELPS TO REDUCE THREE TYPES OF SOLAR HEAT GAIN Insulation provides a thermal barrier, preventing heat transfer from one space to another. This heat transfer occurs in three ways: Conduction: This occurs when heat moves through a particular material, conducting heat from one source ...
