Casement Windows: A Clear Choice for Modern Performance and Timeless Design

When it comes to window design, functionality and design aesthetics are integrally connected. Among the many window options available, casement windows stand out for their versatility, energy efficiency and sleek appearance. At Kawneer, we deliver casement window systems that not only meet the demands of modern architecture but also elevate the occupant experience through thoughtful design and performance.  

In this article, we explore what casement windows are, highlight their key benefits, showcase Kawneer’s versatile range of these window systems and examine their diverse applications across industries. 

What are Casement Windows? 

Casement windows are hinged on the side and open outward like a door, typically operated with a crank. Unlike sliding or double-hung windows, casement windows can open fully, allowing for maximum ventilation and unobstructed views. Their clean lines and minimalist frames make them a popular choice for both contemporary and traditional buildings. Kawneer offers a variety of limit stops and limit devices to limit the opening of a window based on safety and design requirements. 

The Benefits of Casement Windows 

Specifying casement windows for your projects offer a wide range of benefits, including the five features below: 

1. Superior Ventilation – Casement windows have the ability to open, allowing for fresh air to enter the building. This makes them ideal for buildings and spaces in which airflow is a priority. 

1. Enhanced Energy Efficiency – When closed, casement windows form a tight seal against the frame, reducing air leakage and improving thermal performance. Kawneer’s casement window systems are designed with advanced thermal breaks to help meet stringent energy codes and sustainability goals. 

1. Uninterrupted Views – Casement windows offer expansive glass areas that maximize natural light and provide clear, panoramic views that are perfect for commercial spaces, multifamily high-rises and hospitality environments. 

1. Improved Accessibility – Buildings with accessible systems and features can assist occupants with special mobility needs. Thoughtfully engineered to meet accessibility requirements, Kawneer’s architectural aluminum systems help make accessible design a reality. We can provide hardware for our OptiQ® AA®4325 Series Windows that ensures compliance with the Americans with Disabilities Act (ADA) requirement that operable windows should require no more than a 5 lb operating force. Our window hardware also allows for locking, unlocking and operating the window all in one motion with one hand. 

1. Design Flexibility – Available in a variety of sizes, finishes and configurations, Kawneer’s casement windows can be customized to suit any architectural vision. Whether used alone or paired with fixed windows, these solutions integrate seamlessly into curtain wall systems or punched openings.
