Duro-Last is recognized for its energy saving properties, its options for hail protection, its partnership with LiveRoof to provide additional environmental protection, and its ability to extend at end of usable life through sealants that can give your roof an added 10-15 years.
Urban heat islands
As cities become more dense, sunlight on buildings and roads results in a buildup of heat. Known as “urban heat islands,” these areas maintain higher ambient temperatures, even at night, as the retained heat is unable to return temps to normal by the next morning. All of this retained heat leads to higher energy consumption and cooling costs as property owners run air conditioning to maintain comfortable work spaces. In fact, as heat is retained on traditional tar or rubber roofs, ambient temps can reach 200 degrees in the summer. Industrial HVAC systems have to work directly against these blistering temps as they intake and treat air for the building.
Duro-Last provides white and other reflective colors to bounce UV rays up and away from the urban landscape, reducing retained heat and dropping ambient temperatures to a few degrees above city ambient temperatures. This reduces your energy consumption in two ways. First, your building attracts and retains less heat, and your HVAC and air conditioning systems have less temperature to work against as they cool interior rooms and workspaces. Your Duro-Last roof will reduce your energy usage as well as contribute to a cooler city.
I 300 Denver live roof standard
Colorado leads many parts of the country in codes that promote energy efficiency and resistance to heat pooling. The I 300 mandate, which requires commercial roofs of a certain size to install a green roof and/or solar elements to collect the sun’s rays, thus dissipating ambient energy is an example of this trend.
Partnership with LiveRoof
Duro-Last, as a leading manufacturer of PVC roofing systems has created a partnership with LiveRoof, a leading supplier of living roof systems. Because of the Duro-Last origin in swimming pool liners, the system is ideal for supporting rooftop garden systems.
LiveRoof and other green roofs require a chemical fertilizer mix to grow. You need a roof system that can hold up to the treatment that makes a green roof viable. The materials and processes used to manufacture Duro-Last roofs are chemical resistant. Built to resist UV and ozone, these materials serve to protect against the chemicals used to keep your green roof vibrant.
Some rooftop materials are able to be penetrated by root systems. It’s not uncommon to see seeds and dirt collect in corners of rooftops and sprout. On Duro-Last Roofs these unwanted plants can be swept up and removed easily without membrane penetration.
In addition, Duro-Last is an ideal platform on which to grow a LiveRoof. Because the material resists penetration, it keeps your live roof where it belongs, atop the roof where it can soak up the sun and perform as intended.
Resistance to mold and mildew
During the manufacturing process Duro-Last single ply services are treated with fungicides that resist mold and mildew. This treatment works hand in hand with your LiveRoof which requires moisture and can result in growth of rooftop mold and mildew. The Duro-Last system resists these side effects and keeps mold and mildew from penetrating the roof membrane.
