Full Divided Light

Grilles applied to the interior and exterior of the window with aluminum spacers between the glass create an authentic look.

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

Style your window with permanent exterior grilles and choose between permanent or removable interior grilles. 

Removable Interior Grille

For easy cleaning choose removable interior grilles. Secured via a fastener or grille clip, these can be removed easily.

Finelight Grilles Between-the-Glass

Grilles sit between the panes of glass for easy cleaning. 

SmartSun™ Glass

SmartSun™ glass gives you the benefits of Low-E glass, plus it helps shield your home from the sun's heat by filtering out harmful UV rays.

Ideal for: All Climates

SmartSun™ with HeatLock Coating is available on A-Series windows. This prevents more heat from escaping your home but slightly reduces the visible light transmitted through the glass. 

Low-E/Low-E4® Glass

Low-E Glass reflects heat in the summer and helps to retain interior heat in the winter. 

Ideal for: All Climates

Low-E4® with HeatLock Coating is available on A-Series windows. This improves the U-Factor performance of the window but slightly reduces how much light comes through the glass. 

Sun Glass

Sun glass has excellent thermal performance. This glass has a subtle tint that blocks out more heat from the sun.

Ideal for: Southern Climates

PassiveSun® Glass

If you live in a cold climate, PassiveSun® glass allows the sun to heat your home.

Ideal for: Northern Climates

HeatLock® Technology

HeatLock® coating reflects heat that likes to escape your home through window glass. It can be added to most of Andersen's glass options.
