Installing Conklin’s Single Ply Systems in a Minnesota Winter

Over the last thirty years, single-ply membranes have been gaining market share in the United States. The industry’s concern for the environment and an emphasis on energy conservation has become paramount.
.
Single-ply membranes offer a solution – a very cool one. Light-colored, reflective roof surfaces offer building occupants a significant reduction in energy use, and points toward a U.S. Green Building Council LEED™ building certification. Additionally, single-ply membranes offer a lightweight solution that not only accommodates unconventional roof designs, but its durable membrane can be installed year round, even in the harshest climates.

March in Minnesota can be unpredictable especially when installing a single ply system. We were very fortunate to have sunny, yet cool weather for the majority of the installation. By keeping the materials warm, the installation ran smoothly with organization and proper timing.
.
The roof deck on the new construction was a 24 gauge steel V deck. Three and one half (3.5”) inches of Atlas II ISO Board stock (R24) was mechanically fastened to the steel decking. The insulation was staggered for energy efficiency. Conklin’s Flexion 60 mil Single Ply System was mechanically fastened to the steel deck in a fastening pattern that conforms to UL I-90 wind uplift requirements. The membrane was attached to all vertical surfaces using Conklin’s Contact Adhesive. A combination of automatic and hand welders were used to weld all membrane seams. Skylight curbs, stacks, HVAC units, and drains were individually detailed to the new roof surface using factory accessories including pre-fabricated boots, stack covers and corners.
