Aluminum Announces Availability of New Single and Double Hung Window
Pacific Aluminum has announced the immediate availability of the
4250i series, the company's new single/double hung window system
utilizing Insulbar thermal barrier technology.
According to the company the improved insulation performance is
due to increased aluminum separation and air space using material
that is extruded into a shape that effectively and economically
joins two separate aluminum extrusions (the inner and outer aluminum
profiles of the window). This allows for competitive U-Values, exceeding
the performance of pour and de-bridged systems, the company says.
The glass-reinforced nylon has a coefficient of thermal expansion
that is said to be very close to that of aluminum, and should drastically
reduce internal stresses. Use of the Insulbar also allows the new
4250i series to achieve a dual finish capability because separate
interior and exterior extrusions are mechanically crimped to the
Insulbar thermal barrier. Different finishes can be specified for
interior and exterior extrusions, providing true aesthetic design
flexibility in a high performance aluminum window system.
"This is just the beginning of what you will see from us in
the area of new products," stated Loren Nelson, VP Engineering.
"Expect to see more innovations in windows and entrance systems
from Pacific very soon."
Currently undergoing testing, the system is expected to achieve
at least an HC 65 rating, a competitive U-Value and a Level 1 blast
