What Are Smart Heritage Windows?
At a glance, Smart Heritage Windows look like classic steel-framed windows—but the magic is all in the material. Crafted in aluminium, these windows offer the same slender sightlines and elegant profiles but with the modern perks of better insulation, lighter weight, and lower maintenance. Perfect for homes in conservation areas, period renovations, or even modern properties wanting that heritage industrial twist.
Why Heritage Industrial Style Is Trending
Heritage-style windows aren’t just a nod to the past—they’re at the heart of one of the UK’s biggest home design trends right now. With their ultra-slim frames, clean sightlines, and classic steel-look profiles, they bring a touch of timeless elegance to both modern and period properties.
So why the buzz? It’s all about contrast—industrial windows framed in black or anthracite create a bold outline that works beautifully with brick, render, timber cladding or even minimalist interiors. It’s the perfect balance of heritage charm and modern minimalism, and we don’t see it going out of style any time soon.
Meet the Alitherm Heritage 47
Smart’s Alitherm Heritage 47 is the signature product in the Smart Heritage family. The “47” refers to its 47mm frame depth, which is what gives these windows their wonderfully slim and authentic look. But there’s more to them than just looks—they’re built for UK weather, security, and style.
Why It Works: Features That Shine
- Steel-look aesthetics, without the downsides of steel (think rust, cost, and weight).
- Thermally broken aluminium for energy efficiency.
- Slim sightlines, echoing the industrial charm of the 1920s and 30s.
- Multi-configuration flexibility: available as fixed, side-hung, top-hung, and even dummy sashes for symmetrical visuals.
Performance: Thermal Efficiency & Security
Yes, they look beautiful—but let’s talk specs.
- U-Values as low as 1.5W/m²K, thanks to the polyamide thermal break system.
- Double or triple glazing options.
- PAS24 security certification.
- Weather tested to the latest British standards.
So while they bring a timeless appearance to your exterior, they’re firmly built for 21st-century comfort.
Where Can You Use Smart Heritage Windows?
Here’s the thing—they’re more versatile than you think. While they’re ideal for:
- Period property renovations
- Listed buildings
- Loft conversions
They’re also fantastic in:
- Contemporary homes going for a minimalist industrial vibe
- Home extensions and garden rooms
- Commercial-to-residential conversions
Basically, if you want elegance without compromise, these are worth a serious look.
