For homeowners who love the slim, refined aesthetic of steel-framed windows but want the durability, insulation and ease of aluminium, our Decorio heritage aluminium window range delivers both.
Decorio Steel Look
Designed by Decorio in Lancashire, these steel-look aluminium windows allow you to capture industrial, Art Deco or heritage styling while enjoying contemporary performance.
Features and Benefits Overview:
Steel-look Aesthetic
- Profile sightlines from as little as 59 mm, ensuring a sleek, minimal frame that mimics traditional steel windows.
- Outer frame options: 48 mm or 33 mm depths, giving flexibility in appearance and installation.
- Available with astragal bars and heritage detailing to replicate steel-window grid style — ideal for conservation or character properties.
Modern Performance & Durability
- Aluminium construction with polyamide thermal break technology, offering significantly better insulation than steel and compliant with current standards (e.g. Document L).
- Low maintenance: aluminium does not rust or warp like steel or timber, requiring only a wipe-clean finish.
- Built to last: manufacturer cites a 40+ year life expectancy in typical UK conditions.
Customisation & Specification Options
- Over 200 RAL & BS colour choices, including dual-colour finishes (interior/exterior) and textured finishes.
- Glazing options: high-performance double glazing as standard, with options for laminated/toughened glass, trickle vents, etc.
- Suitable for external windows: top-hung, side-hung or fixed units, tailored dimensions for your project.
