A Brief History: From Ironworks to Icon

The "Crittall" look takes its name from Francis Henry Crittall, an ironmonger from Essex who pioneered the manufacturing of steel windows in the late 19th century.

  • The Victorian Origins: Originally designed for durability in industrial settings, these gridded windows allowed Victorian factories to have massive glass walls, flooding workspaces with light while maintaining structural strength.
  • The Art Deco Era: By the 1920s and 30s, the style moved from factories to high society. It became the signature of the Art Deco and Modernist movements, featuring in everything from the Houses of Parliament to the finest London apartment blocks.
  • The 21st Century Revival: Today, the style has been reclaimed as the ultimate "industrial-chic" interior feature. It bridges the gap between historical character and modern minimalism, making it as suitable for a 1930s semi-detached in Dublin as it is for a converted warehouse in Manchester.

Why are black-framed internal doors trending in 2026?

Homeowners in the UK and Ireland are moving away from full open-plan layouts toward "broken-plan" living. Industrial-style aluminium doors (often called Crittall-style) allow for spatial zoning without losing natural light, offering a sophisticated, minimalist aesthetic that enhances both home value and resident well-being.


The Shift to "Broken-Plan" Living

The era of the "echo-chamber" open-plan house is over. Today, the focus is on zoning.

  • Zoning Without Walls: Use glazed screens to create a home office or dining room without the mess, dust, or cost of major masonry work.
  • Maximising "Borrowed Light": Slim aluminium profiles allow sunlight from external windows to reach deep into dark hallways—a concept known as "borrowed light."
  • Acoustic Well-being: High-quality glazing acts as a sound barrier, reducing the stress of shared-space noise while maintaining a visual connection to the family.
Technical Comparison: Aluminium vs. Steel

Is aluminium better than steel for internal glazing? Yes. While steel offers a traditional heritage feel, aluminium is more sustainable, cost-effective, and significantly easier to install in modern residential settings.

Feature Aluminium (Loftstyle) Traditional Steel
Weight Lightweight yet robust - Approx 1/3 the weight of steel Very heavy (may require structural reinforcement)
Installation Fast; easy to handle on-site Complex; requires may require welding/specialists or offsite fabrication
Sustainability 100% recyclable, using minimal energy to reuse Recyclable but requires high-carbon manufacturing
Maintenance Corrosion-resistant; powder-coated Prone to rust if chipped
Affordability Budget-friendly Expensive

Frequently Asked Questions

Can I install Loftstyle doors in a regular door opening?
Yes. The Loftstyle system is designed to be highly adaptable. Because profiles are supplied in stock lengths, they can be tailored to fit standard UK door apertures or expansive custom openings.

Do I need special structural support for aluminium screens?
Generally, no. Because aluminium is approximately one-third the weight of steel, most standard internal walls and floors can support the system without the need for additional RSJs or structural reinforcement.

Is the glass safe for homes with children?
Absolutely. We recommend and support the use of toughened safety glass or laminated glass. Our technical team can advise on the correct glass thickness

How do I design the grid layout?
That is the best part of the Loftstyle range! You aren't stuck with a factory preset. Using our drawing services, you can experiment with different horizontal and vertical bar placements to create a look that is unique to your home.

How do I maintain aluminium frames?
Aluminium is incredibly low-maintenance. Unlike steel, which may require specialist treatment to prevent rust, our powder-coated aluminium only needs an occasional wipe with a damp cloth and mild detergent to stay looking brand new.

Why is Aluminium more sustainable than steel?
Aluminum is generally considered more sustainable than steel because it is infinitely recyclable without losing quality, with recycling requiring 95% less energy than primary production. Its high strength-to-weight ratio allows for lighter products, reducing transportation emissions, while its natural corrosion resistance eliminates the need for eco-harmful coatings
