Specialty Products Allow Architects to Dream Bold Designs

A building can reflect an architect's dreams and desires to turn the ordinary into something remarkable. Frank Lloyd Wright dared to build Fallingwater. Le Corbusier's urban ambition is evident in the U.N. Headquarters. The twists and curves of the Guggenheim Museum Bilbao are an extension of Frank Gehry's imagination. Although the designs may not appeal to everyone's taste, they all demonstrate the willingness of architects to dream new concepts and turn them into reality.


Pivotal Advice: When hanging a door, it's wise to obey the laws of physics

Gravity. Momentum. Inertia. Resistance. Energy.

These terms hold much clout in the world of physics. They are the unseen but easily understood forces that, quite literally, make the world go round. The world of doors and hardware is no different; gravity, momentum, inertia, resistance and energy are always at play. Unfortunately, when it comes time to hang a door the rules of physics are not always followed, leading to doorways that are warped, malfunctioning, and in the worst case scenario, in need of replacement.
