Every Ellison door is 100% custom. Choices in material, finish, size, hardware, and style are only the beginning. The final design is determined by the vision of the project team and the functional needs of the project.
Ellison balanced doors made from tempered glass are “all-glass” doors that feature a top and bottom rail that secure the glass to the hinging mechanism. Rails can be made of stainless steel, bronze, or aluminum. Bronze and stainless steel rails are a minimum of 4-¾” in height and standard aluminum rails are 4-¾” and 10” in height. ½” tempered glass is used for balanced doors from 8’-0” to 9’-0”. ¾” tempered glass for doors higher than 9’-0”.
Balanced doorframes for tempered glass doors are available in your choice of stainless steel, bronze, or aluminum. The torsion bar closer spring can be either concealed within the doorframe or exposed. These doors can also be equipped with Ellison PowerNow power operators.
Ellison's revolutionary PowerNow Design
An Ellison PowerNow-equipped balanced door features a low energy operator, concealed in the frame header, and an actuating arm that provides the opening force on demand. Ellison’s standard hardware provides the closing force.
When power is not needed during manual operation, Ellison PowerNow-equipped balanced doors operate the same way as standard Ellison balanced doors – the power operator is never engaged, reducing operator wear and maintaining Ellison’s signature manual ease of operation.
Any Ellison balanced door can be specified as PowerNow-equipped. Power operators are available in your choice of two leading manufacturers – Stanley and Horton.
USES AND APPLICATIONS

Life Cycle: The average lifespan of a typical high-traffic commercial entry door is about 10 years. For an Ellison custom balanced door, the expected lifespan is 80 years and counting. Many of the earliest Ellison balanced doors (from the 1930s) remain in operation to this day. This means, in time, at least seven doors would have to be manufactured to serve the duration of just one Ellison custom balanced door.
Materials: Ellison custom balanced doors (excluding wood doors) are comprised almost entirely of metal and glass, two of the world's most readily recyclable and upcyclable materials. Only two very small – but critical – components are polymer-based, to ensure long term corrosion resistance. What's more, most Ellison doors are made from particularly valuable metals like bronze and stainless, which helps to ensure their eventual recycling.
Manufacturing: Ellison produces nearly the entire balanced door in-house. For example, all balanced hardware is cast in Ellison's foundry and tooled in Ellison's factory. Virtually no material is wasted, as unused material is remelted for reuse. Also, under a sustainable manufacturing program sponsored by the New York State, Ellison has implemented manufacturing systems that maximize both water and energy conservation.
