Cool Roof Performance: 6 Truths About Cool Roofs

Cool roofs can help save you money on energy bills* in the North as well as the South. Apart from energy savings and lower monthly bills, your building might qualify for certain financial incentives from local and federal governments. Plus, you'll do your part to ensure that your building is more environmentally friendly due to your cool roof performance.

    How will ASCE 7-16 affect the low-slope roofing industry? A Tale of Two Buildings

    A common question being asked in the roofing industry is whether or not the 2016 version of ASCE 7 is going to increase the design wind pressures acting on a building. The answer is "yes" in many cases. So, the follow up question is "by how much?" And, that leads to the next question, "how much more capacity will roof systems be required to have when wind design follows ASCE 7-16?"

    The Physics of Thermal Inertia in Low-Slope Roof Design

    What are the key material properties? In a previous article the use of thermal inertia to slow down heat flux through a roof assembly was discussed. In buildings where air conditioning costs dominate and heating use is relatively low, higher thermal inertia assemblies can potentially improve energy efficiency. This is particularly the case of buildings such as offices that are only occupied during daylight hours. Thermal inertia could delay the transmission of heat into a building towards the end of the day, increasing thermal comfort and allowing facility managers to reduce cooling during the day.

    Designing with Polyiso

    Thermal insulation is an important part of commercial roofing assemblies. As with anything, there are ways to design with and install polyiso insulation — a better way, a best way, and many variations in-between! What may be best in terms of lowest up-front costs, may prove only good or worse over the long-term life of the building.
