Duro Last PVC Commercial Roof Austin TX
The Duro-Last PVC (Poly Vinyl Chloride) reflective roof membrane is a proprietary thermoplastic formulation made up of plasticizers, biodieds, PVC resins, stabilizers, flame retardants and ultraviolet sun rays absorbents. It uses a weft-insertion knitted scrim that is sandwhiched between two layers of PVC film which gives the membrane its strength and durability. The Duro-Last membrane comes in assorted colors; white, tan, gray, or dark gray.
This product has met and exceeded all major fire and wind code regulations including tier 1 windstorm rated and regional approvals as necessary across country. These certifications are a testament to Duro-Last's leadership in providing the consistent, watertight integrity that facility managers and owners expect.
Duro-Last is proud to be a charter partner of the ENERGY STAR® Roof Products Program. The ENERGY STAR label indicates to facility owners and managers that the Duro-Last white vinyl roof membrane will save them money on cooling costs, compared to conventional roofing membranes, due to its high reflectivity; 88% reflective of the sun's energy which is at the top of reflective roofing membranes. Being a charter member of the Cool Roof Rating Council, CRRC, and a member of the United States Green Building Council, USGBC. They also take part in all the roofing industry major technical committees which includes the American Society of Testing Materials, ASTM.
Cool Zone - Setting the Standards in Cool Roofing
In the commercial roofing industry, reflective and cool roofing is the preeiminent discussion topic now for over a decade, plus the Duro-Last® Cool Zone® roofing system is considered the standard for single-ply reflective roofing and the energy savings as a result of its reflectivity. In terms like sustainability, cool roofs, and cool roofing by Duro-Last is getting a lot of attention plus it is setting the standards at which the industry stives for.
What is sustainability and cool roofing? For building owners, facility managers, contractors, architects, and other specifiers it means that roofing materials must satisfy the design, construction, maintenance, life-cycle impact, adaptive re-use, destruction, and the recycling of it so it will meet the long-term environmental impact standards demanded by today’s high-performance buildings.
Sustainable Roofing? the roofing system must meet the five E’s of high-performance roofing: Energy, Environment, Endurance, Economics, and Engineering. When compared to these standards Duro-Last Cool Zone roofing system not only meets the standard it leads the commercial roofing industry in super compliance.
Energy Efficient Roof: What Reflective Roofing Delivers
High-performance roofs reflective roofs dramatically reduces energy consumption. Duro-Last Cool Zone reflective roofing, when used with appropriate insulation on low-sloped or flat roofs, will provide a high-emissivity system will provide the facilities manager and building owners will:
- Building energy consumption is reduced by up to 40 percent
- R and K insulation factor is increased and thus reduce winters heat loss and summers heat gain
- Productivity of roof top air conditioning units is increased
- HVAC capacity requirements tonage size is and seer rating is impresively reduced
- Urban Heat Islands effect and associated urban air pollution is reduced as a result
- An Energy Efficient Roof is created
Duro-Last Cool Zone Roofing Systems
reflective roofing membranes meets and surpasses cool roof standards established by these organizations:
- EPA's ENERGY STAR® Roof Products minimum standard; low-slope reflective roof products must have 65 percent reflective initially plus retain 50 percent reflective after 3 years weathering. Cleaning the membrane periodically can restore its reflectivity. You can check here to see all the ENERGY STAR Roof Products at www.energystar.gov. Plus you can use their online calculator to determine potential energy savings for your facility
- The Cool Roof Rating Council (CRRC) is a non-profit association that implements and promotes fair, accurate performance ratings for solar reflectance and emittance from roof surfaces. All tests for measuring reflective roofing properties are performed by accredited, independent laboratories following established ASTM International protocols. Performance data for products from numerous manufacturers can be found on the CRRC’s web site, www.coolroofs.org.
- Title 24 of California's Energy Efficiency Standards for Residential and Nonresidential Buildings is a wide-ranging “green” construction bill that became effective in October, 2005. Title 24 specifies that new and replacement commercial roofs – virtually any low-slope roofing project that requires a construction permit – must have a minimum initial thermal emittance of 75 percent, and a minimum initial solar reflectance of 70 percent, as rated by the Cool Roof Rating Council.http://www.energy.ca.gov/title24/
Other Energy Considerations:
- The American Society of Heating, Refrigeration and Air-Conditioning Engineers (ASHRAE) established Standard 90.1 as a minimum requirement for energy-efficient building design. President Bush has signed legislation offering tax deductions to buildings that exceed the 90.1 Standard.
- Lawrence Berkeley National Laboratory recently determined that increasing the R-value of a roofing system in Los Angeles from R-9 to R-15 would reduce annual energy costs by $2,500 and lower carbon dioxide emissions by thousands of pounds.
- Executive Order 13123, now known as Federal Acquisition Regulation Case 1999-011, mandates that federal office buildings must reduce energy usage 30% by 2005, and 35% by 2010. It also mandates that federal industrial buildings and laboratories must reduce energy consumption 20% by 2005, and 25% by 2010. Federal agencies also must use ENERGY STAR products when available, and decisions must be based on energy and life-cycle cost analyses.
- In cooperation with state and local governments, many utility companies offer rebates for using reflective roofing systems. These rebate programs are offered nationwide, not just in southern climates. For instance, Excel Power, the fourth largest utility company in the United States, has awarded rebates as far north as Minnesota.
- Energy efficiency also reduces pollution by mitigating the urban heat island effect (see http://eandE.LBL.gov/heatisland).
