Building exterior with 700 Series casement replacement windows

P-Tek 700 Series Casement Windows

Architectural performance with modern design flexibility.

The P-Tek 700 Series is a high-performance casement window system designed for projects that demand superior ventilation, energy efficiency, and clean architectural lines. Unlike traditional sliding or single-hung windows, casement designs open outward, creating tighter seals and improved airflow.

Built for custom homes, modern designs, and high-end applications, the 700 Series delivers a refined appearance while maintaining the durability and performance expected from P-Tek window systems.

The preferred choice for projects where design, airflow, and energy efficiency are top priorities.
