THE PERFECT FIT

• Thicker exterior sash walls (.090” versus .068”)

ENERGY EFFICIENCY

• Rated Most efficient by Energy Star
• Warm edge spacers recessed between the panes of glass both minimize glass edge conductivity while optimally containing the argon gas within the sealed units, obtaining a 90% argon gas fill rate

SUPERIOR QUALITY AND DURABILITY

• Fusion Welded vinyl chambers
• Offset groove creates a natural drip edge so water flows away from your window
• Internal steel reinforcement channel to ensure optimal performance and operation for larger windows.
• Mullion reinforcement pocket to facilitate structural reinforcement when combining large units.

PEACE OF MIND
