Dynamic Wind Uplift Testing Services for Roof Membrane Systems

Element specializes in testing roof membrane systems, including MARS (mechanically attached membrane), PARS (partially attached membrane), and AARS (adhered membrane). Our tests cover a wide range of materials and components, including:

• Membranes: Including PVC, TPO, EPDM, and modified bitumen.
• Insulation: Polyiso, EPS, XPS, and Mineral Wool.
• Vapor & Thermal Barriers: Ensuring thermal efficiency and moisture protection.
• Adhesives & Primers: Testing the strength and longevity of roof membrane adhesives.
• Base & Cap Sheets: Ensuring complete system durability under wind uplift conditions.

Our testing environment allows us to simulate real-world conditions, so we can measure performance in a variety of ways:

• Dynamic uplift resistance (DUR) rating determination: We determine the DUR to ensure your roofing system can withstand specific wind uplift loads based on geographic location and building requirements.
• Wind pressure cycle simulation: Our chambers simulate actual wind conditions, testing the roof membranes’ ability to resist wind pressures that could lead to system failure.
• Air leakage rate measurement: We assess membrane integrity by measuring air leakage rates, ensuring your system can also function as an air barrier.
• Complete System Testing: We evaluate not just the membrane itself, but also its interaction with insulation, vapor barriers, adhesives, and other components to ensure comprehensive system performance.

Our testing subjects your roofing systems to dynamic wind load cycles based on actual wind pressure records. This helps validate performance and identify potential weaknesses before installation.

Element’s dynamic wind uplift testing is supported by our advanced testing chambers, which are designed to meet rigorous industry standards. Our chambers simulate wind pressures from 20 kPa (400 psf) to 10 kPa (200 psf), and can accommodate roof samples up to 19 feet (5,791 mm) in size. With multiple test frames, we can conduct simultaneous testing for efficiency. Additionally, we measure air leakage rates to evaluate roof systems as air barriers, ensuring thorough testing for structural integrity and wind resistance.

• Wind uplift testing chamber capable of 20 kPA (400 psf) pressure
• Multiple test frames for simultaneous testing
• Large-scale testing capability (up to 1,880 mm x 5,791 mm samples)
• Air leakage measurement equipment

Element is the only independent third-party laboratory in Canada accredited to conduct dynamic wind uplift testing in accordance with CSA A123.21 and CAN/ULC-S742 standards. Additionally, we operate in North America, further enhancing our capabilities and reach in providing exceptional testing services.
