4400 - 4450 Series PDF

The 4400 series double slider can be easily applied to new construction and renovation projects in the housing as well as commercial markets.  The 4 9/16” deep frame, with a flush exterior, allows for a wide range of interior and exterior accessories to create the perfect window system for your project.

The window profiles are made from an exclusive, 100% virgin uPVC powder compound that is entirely lead-free.  This compound gives the system better resistance to impact and discolouration. 

Window profiles are fusion welded, which gives a more attractive appearance, as well as supplies a 100% watertight and airtight surface.  Fusion welding increases the overall structural strength for both the window frames and sashes.

Our multi-chambered profiles provide superior thermal performance as well as excellent sound abatement qualities.  The double walled glazing bead and sliding handle glazing bead is remarkably sturdy and provides clean glass lines.

Internal screw bosses and extra walls ensure sturdy hardware attachment as well as sturdy installation options through the frame for time-tested placement.

Multiple pile weather-strips with fin-seal provide remarkable air tightness, helping to reduce heating and air conditioning costs.

Due to the function of a sliding sash, the single slider is ideal for openings on patios, walks or verandas.  The single operating sash lifts out for easy access to the exterior of the sash, providing cleaning accessibility from the indoors. 

The single slider system is ideal for a broad range of glass type options in a double pane configuration for excellent thermal efficiency. 

An interior ½” built-in return as well as an exterior accessory grooves allow for additional moldings, such as interior jamb extensions as well as exterior brickmoulds and nailing flanges.

The single slider along with panoramic picture frame creates beautiful stacking and mulling configurations.
