Built for Rock River Weather
Dixon buildings take a beating from freeze-thaw cycles, heavy snow loads and summer storms rolling across Lee County. Flat roofs are especially vulnerable when water sits and freezes. Duro-Last’s white PVC membrane is heat-welded at the seams and resists punctures, chemicals and fire. As part of a properly insulated roofing system, it can also improve energy efficiency—helping keep heat in during the winter and cool air in during the summer. It’s a strong fit for warehouses, retail and manufacturing buildings in the Sauk Valley.
