For this Palm Beach residence, Cornerstone supplied and installed Kolbe Ultra Series double-hung windows, French doors, and fixed windows, balancing timeless design with advanced coastal durability. All units were finished in a crisp Ultra Pure White 2605 Kynar aluminum coating, offering long-term performance in harsh marine environments. The fenestration system was glazed with monolithic laminated clear glass, providing clarity, impact resistance, and a seamless visual aesthetic.
