4400 - 4450 Series PDF

The 4450 series single hung 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 wall structure.

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 lifting 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.

Due to the function of the sliding sash, the single hung is ideal for openings on patios, walks or verandas.  The single hung lower sash tilts in for easy access to the exterior of the sash, providing cleaning accessibility from the indoors. 

The single hung along with the panoramic picture frame create beautiful stacking and mulling configurations.

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

The most reliable balance system available, the stainless steel Constant Force coil balances provide a heavy duty sliding operation for your windows.  Operation is smooth, consistent, and effortless and never needs adjusting.  The balance system also comes with and integrated tilt shoe and pivot bar which allows the window to achieve higher structural loads.

The single hung 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.
