APA Casement Window System
Overview
The APA Casement Window is a modern outward-opening window system designed for residential homes that want style, performance and reliability. It blends timeless design with strong thermal efficiency, making it a practical choice for any contemporary living space.
Thermal & Acoustic Performance
The frame uses high-performance thermal breaks and durable aluminium profiles that reduce heat loss and improve indoor comfort. Because of this design, the APA Casement Window supports excellent insulation levels and acoustic control. With the right glazing, it helps maintain a comfortable, quiet and energy-efficient home throughout the year.
Smooth Operation & Practical Design
This outward-opening window is easy to operate and allows for maximum ventilation. It works well in living rooms, bedrooms, kitchens and extensions where airflow and space efficiency are important. The slim, elegant sightlines offer a clean look that suits both modern homes and high-end refurbishments.
The window is available in a range of opening styles, including top-hung and side-hung options. These allow designers and homeowners to match the right opening type to each room’s needs.
Durability & Low Maintenance
Every APA Casement Window is made from sustainable aluminium and tested to leading European standards. It offers long-term durability and requires very little maintenance. The strong aluminium construction ensures resistance to weathering, corrosion and everyday use, even in exposed locations.
Design Flexibility
The system integrates seamlessly with our wider residential range, allowing consistent design across an entire property. It is available in single or dual-colour finishes with high-quality polyester powder coating. These finishes help match exterior architecture while maintaining a premium interior appearance.
