Crittall Windows: Design Features and Installation Guide

Crittall windows are celebrated for their timeless aesthetic and versatility in various architectural styles. Known for thin steel profiles that maximize light and elegant frames, these windows are popular in both residential and commercial settings. Their design enhances a building’s visual character while offering durability and energy efficiency.

Design Characteristics

Crittall windows are distinguished by slender steel frames that maximize glass area, enhancing visual appeal and allowing natural light to flood interior spaces. The use of hot-rolled steel sections provides both strength and elegance, suitable for various architectural styles. These windows can be customized for different configurations, from traditional multi-pane designs to contemporary large glass panels. Powder coating the steel frames in various colors adds to their adaptability, complementing any design palette.

Material Composition

The appeal of Crittall windows is rooted in their material composition. Steel, known for its strength and durability, is often galvanized to resist corrosion, extending the life of the frames. Modern advancements in glazing technology, such as low-emissivity (low-E) glass, improve thermal performance by reflecting heat while allowing light to pass through. This enhances energy efficiency, reducing heating and cooling costs, especially in climates with extreme temperature variations.

Types of Crittall Windows

Crittall windows offer styles to suit different architectural needs and aesthetic preferences, providing tailored solutions for residential and commercial projects.

Fixed

Fixed Crittall windows provide unobstructed views and maximum light entry without opening capability. Ideal for spaces where ventilation is secondary, they are often combined with operable windows for a cohesive system balancing aesthetics and functionality. The robust steel frames ensure structural integrity, suitable for large glass panels that serve as striking architectural features. Customizable in size and shape, they integrate into various design schemes, from modern facades to historical restorations.

Casement

Casement Crittall windows, with their side-hinged design, open outward like a door, offering excellent ventilation. Versatile for both traditional and contemporary settings, they combine classic looks with modern functionality. The steel frames support the glass while maintaining a slim profile, ensuring aesthetic appeal. Secure locking mechanisms and weather-tight seals enhance energy efficiency and security, making them practical for various applications.

Awning

Awning Crittall windows, top-hinged and opening outward from the bottom, provide rain protection while allowing ventilation. This design is advantageous in areas prone to inclement weather, enabling airflow without water entry. Often used with fixed windows, they create a dynamic and functional arrangement. Steel construction ensures durability and resistance to environmental elements, while customizable size and finish allow them to blend with different architectural styles. Their unique opening mechanism also suits spaces where privacy and security are important, as they can be positioned higher on walls.

Pivot

Pivot Crittall windows rotate on a central axis, allowing controlled ventilation and easy cleaning. Suited for modern and industrial-style buildings, they make bold architectural statements. Steel frames provide strength for the rotating mechanism, ensuring smooth operation and longevity. Customizable to fit various sizes and configurations, they are versatile for both large and small openings. The unique functionality and aesthetic appeal of pivot windows attract architects and designers seeking innovative elements.

Installation Considerations

Installing Crittall windows requires careful planning and precision. Experienced installers familiar with steel window systems are advisable, as they understand the specific challenges and requirements. The process begins with assessing the building’s structural conditions to accommodate the weight and design of the steel frames, which are heavier than aluminum or vinyl counterparts.

Proper site preparation is essential, as the area must be free of obstructions and reinforced to support the robust frames. This may involve installing additional steel supports or lintels, particularly in older buildings. Precise measurements ensure a snug fit, minimizing air or water infiltration. High-quality sealants and weatherproofing materials complement the durability of the steel and maintain energy efficiency.
