Typical Installations






PolyPro Testing

Wind Tunnel Laboratory
The wind tunnel lab allows us to gather precise data with 270° of measurement on terminations. All data is analyzed for product performance under rigorous conditions before going to market.

Rain Testing
Labs test the vapor/moisture barrier of products by subjecting them to extreme rain and wind conditions.These tests are compliant with both the US and Canadian requirements as well as the stringent European standards.

Climate Testing
Labs have developed a patented ice testing system in the climate room. Tests run to -4°F (-20°C). PolyPro vertical terminations are engineered to remain icicle free.
Commercial and OEM Product Development
DuraVent engineers are expertly skilled to develop venting components to OEM specs. To satisfy specific venting requirements, DuraVent has the experience to provide custom design, prototyping and testing of vent systems and components engineered to the demands of specific appliances.
