Mercury Energy Efficient Door and Frame System


The new Mercury door is paired with the recently launched Mercury thermally broken frame stocked at select ASSA ABLOY service centers for fast delivery. The new Mercury door and frame system is priced approximately 10% lower than similar energy efficient solutions.

The innovative Mercury door incorporates a patent pending Freon-free polyurethane foam and steel reinforced core. The new sustainable foam used in the Mercury door will also be the standard for all Fleming foam-in-place core doors beginning this month. The new foam has an extremely low Global Warming Potential rating (GWP) compared to the previous formulation.

The new Mercury door and frame system has been independently tested for thermal performance (U value of 0.37) in accordance with NFRC 102-2014 and ASTM test methods. The door and frame system was also tested for resistance to air infiltration with (0.10 cfm/sq ft) in accordance with NFRC 400-2014 and ASTM test methods.
