777E - Trio-E Energy Efficient Opening Solutions

Approximately 40% of all energy leakage comes from the building envelope* this includes exterior doorways. Trio-E doors installed with CURRIES Thermal Break frames and Pemko Thermal Barrier Saddles help increase thermal retention and reduce energy leakage.

Trio-E is a new patent pending door design that delivers superior insulated values and strength plus, provides aesthetic qualities desired in today’s commercial building applications. The “E” is for energy efficiency and Trio-E has the lowest U-Factor (0.29) for a steel stiffened door in the market today. The U-Factor of 0.29 was achieved in an operable condition (ASTM1363) using the CURRIES Thermal Break Frame and Pemko 273x3AFG Thermal Barrier Saddle. The Trio-E will provide years of strength and sustainable energy savings for any building.
