Steel vs. Aluminium Crittall-Style Windows: Which Are Best?

The choice between steel Crittall and aluminium Crittall-style frames can significantly impact the aesthetics, durability, and functionality of your home, and it’s a choice you might be making if you’re considering Crittall windows for your home.

While both materials have their merits, the emergence of aluminium alternatives has introduced a new era of possibilities for homeowners in the UK. Today we’re delving deeper into the distinct advantages of opting for aluminium Crittall-style windows over traditional steel frames, highlighting the superior qualities that make them a modern favourite.

Strength and Durability: Aluminium’s Advantage

Steel has long been favoured for its strength and durability in window construction. However, aluminium Crittall-style windows offer comparable robustness with the added advantage of corrosion resistance. 

This is particularly advantageous in coastal areas or regions with high humidity, where steel frames may succumb to rust over time. Aluminium, on the other hand, maintains its integrity even in harsh weather conditions, ensuring longevity and reliability for years to come. 

Whether it’s resisting corrosion, withstanding strong winds, or enduring temperature fluctuations, aluminium Crittall windows emerge as a resilient choice for homeowners seeking durable window solutions.

Lightweight Construction: Ease of Installation

The weight of steel frames can pose logistical challenges during installation, requiring specialised equipment and labour-intensive processes. In contrast, aluminium Crittall-style windows boast a lightweight yet sturdy construction, making them significantly easier to handle and install. 

This not only streamlines the installation process but also reduces the strain on the building structure, minimising the risk of damage during transportation and fitting. 

Whether you’re renovating an existing property or embarking on a new construction project, the lightweight nature of aluminium frames enhances efficiency and convenience, allowing for smoother installation and quicker turnaround times.

Energy Efficiency: Aluminium’s Thermal Break Technology

In today’s era of energy consciousness, the thermal performance of windows plays a crucial role in reducing heating and cooling costs. Aluminium Crittall-style windows excel in this aspect, thanks to innovative thermal break technology. 

By incorporating insulating materials within the frame, aluminium windows effectively minimise heat transfer, improving thermal efficiency and reducing energy consumption. This not only enhances comfort levels indoors but also contributes to lower utility bills and a reduced carbon footprint. 

Whether you’re aiming to achieve energy efficiency certifications or simply seeking to create a more sustainable living environment, aluminium Crittall windows offer a practical solution for minimising energy wastage and maximising comfort.

U-Value and Building Regulation Compliance

Understanding the significance of U-values in thermal performance will certainly help you choose between steel and aluminium Crittall-style windows. Aluminium has better thermal performance compared to steel, meaning aluminium Crittall-style windows can achieve lower U-values, making them well-suited for meeting or exceeding building regulation standards. 

This compliance is essential for obtaining sign-off on construction projects, ensuring that windows contribute to energy efficiency and indoor comfort. By selecting aluminium Crittall-style windows, homeowners can achieve both aesthetic appeal and regulatory compliance, providing peace of mind and assurance of quality for their homes.

Design Flexibility: Customisation Options

While steel Crittall windows are renowned for their classic industrial aesthetic, aluminium offers greater design flexibility and customisation options. Aluminium frames can be powder-coated in a myriad of colours—over 500 RAL colours to be exact—allowing homeowners to personalise their windows to match their interior and exterior design preferences. 

Additionally, aluminium’s inherent strength enables the creation of slim sight-lines and larger glazed areas, maximising natural light and enhancing the overall visual appeal of your home. Whether you’re aiming for a sleek, contemporary look or a more traditional aesthetic, aluminium Crittall-style windows can be tailored to suit your unique style and architectural requirements.

Aluminium Crittall-Style Windows Set the Standard

The benefits of aluminium Crittall-style windows over steel frames are clear. From enhanced durability and ease of installation to superior energy efficiency and design versatility, aluminium Crittall-style windows offer a modern solution for homeowners seeking both style and functionality. 

Whether you’re renovating a period property or building a contemporary masterpiece, aluminium Crittall-style windows provide the perfect blend of durability, efficiency, and style for your home.
