Cool Roofing: Is Summertime Heat Sending Your Energy Costs Through the Roof?
A white PVC membrane is both highly reflective and highly emissive. This transfers less heat into the building compared to a dark colored “non-cool” rooftop. As the sunlight hits the building, it is pushed away rather than being absorbed. Even in colder climates, building owners are discovering the benefits of these roof systems.
Cool Roofing Benefits
- They can be 50 degrees cooler or more during hot summer days when compared with other roofing materials.
- Reflective roofing systems save money and energy during peak energy demand periods – typically mid-days, when electricity demand and costs are highest.
- The cooler rooftop surface can reduce the cost of operating rooftop HVAC units because the units will use cooler air than if mounted on a dark roof surface.
- Reducing the urban heat-island effect by reflecting solar heat rather than absorbing and transferring it to buildings.
- By keeping moisture out while reflecting ultraviolet (UV) and infrared (IR) radiation, a reflective roof can help to protect underlying insulation and the roofing substrate from deterioration
