A-Series
Specialty Shape Windows

Give your window an authentic look with grilles that are permanently applied to the interior and exterior of your window with an aluminum spacer between the glass. 

Spacer Option for Greater Energy Efficiency

The Energy Spacer option is available to help A-Series products with full divided lights and SmartSun™ glass be ENERGY STAR^® certified in the Northern climate zone. Its narrow design creates a 3mm gap around the spacer, helping to lower U-Factor values.

Simulated divided light offers permanent grilles on the exterior and and a choice of permanent or removable wood interior grilles, with no spacer between the glass. 

Removable interior wood grilles are secured via a fastener or grille clip and can be removed enabling you to easily clean the glass surface.

Finelight™ grilles are suspended between the panes of glass, allowing you to easily clean both the inside and outside of your windows and doors.
