Introduction: Architecture in the Age of Glass
If the past decade was about open-plan living, the next is about open-light architecture.
Homeowners want transparency, natural light, and connection — not just between rooms, but between indoor and outdoor spaces.
For architects, that shift presents both opportunity and challenge. Every new design now demands glazing that’s structural, thermal, and aesthetic — all at once.
That’s where integrated glazing systems come in. From sliding and bi-folding doors to aluminium and uPVC windows, and from roof lights to lanterns, the modern glazing toolkit gives architects the power to define form through light — without compromising on performance or compliance.
And through The Trade Village, that toolkit becomes accessible, specifiable, and ready for real-world construction.
Light as a Building Material
Natural light is more than a feature — it’s a construction material in its own right.
Handled well, it can elongate a space, alter mood, and even redefine perceived scale. But to harness light properly, glazing must balance clarity, thermal control, and structural precision.
The new generation of glazing systems achieves exactly that:
- Slimmer profiles open up more glass-to-frame ratio.
- Thermally broken aluminium maintains energy compliance without heavy frames.
- Advanced glazing offers solar control, low-E coatings, and acoustic reduction.
- Integrated product families ensure consistent sightlines across doors, windows, and roofs.
In other words — it’s now possible to design with light instead of merely designing around it.
The Modern Glazing Palette – From Floor to Ceiling to Sky
Sliding & Bifold Doors – Framing the Threshold Between Inside and Out
The transition between interior and exterior space has become the defining move of modern residential architecture.
Sliding systems deliver continuity and calm — ultra-slim aluminium frames, vast spans, and seamless operation. Korniche and Cortizo systems, available through The Trade Village, make minimalism achievable even in domestic builds, with:
- 20–30mm sightlines.
- Panels up to 3m wide.
- PAS 24 security compliance.
- Thermal U-values from 1.3 W/m²K.
Where minimalism meets movement, bifold doors step in. Smart Aluminium bifolds bring rhythm and flexibility — adaptable panel configurations, quick-glaze beads for simpler fitting, and thermally broken profiles that comply with Part L.
Architectural relevance:
Sliding doors frame the view. Bifolds choreograph the space. Both define how occupants experience light and movement within the architecture.
Windows – The Architectural Constant Reimagined
No building component is more deceptively simple than a window — or more important to get right.
Aluminium Windows – The Architectural Essential
Aluminium windows have become the material of architectural intent. With systems like Smart Alitherm and Cortizo Aluminium, architects can maintain:
- Consistent material language across fenestration and doors.
- Minimalist frames (typically 60–70mm) to maximise daylight.
- U-values as low as 1.1 W/m²K for compliance.
- Over 200 RAL options, plus anodised and textured finishes.
They suit everything from contemporary extensions to bespoke new-builds, delivering both elegance and endurance.
uPVC Windows – The Value Optimiser
Not every project calls for metal. Deceuninck Heritage and Eurocell systems provide thermally excellent, aesthetically versatile options for cost-sensitive builds.
Their flush sash profiles mimic timber, while offering energy ratings that outperform many aluminium alternatives.
Architectural takeaway:
Use uPVC to achieve compliance within budget, and aluminium to achieve distinction through design — both from one supplier, with matching finishes if desired.
Roof Lights & Roof Lanterns – Bringing the Sky Indoors
Roof glazing has shifted from luxury to expectation. It’s how architects now introduce light into the heart of the plan — kitchens, extensions, and stairwells that would otherwise sit in shadow.
Flat Roof Lights
Systems such as Atlas Flat Rooflight and Korniche Flat Glass Roof Light combine:
- Ultra-slim internal frames for a frameless ceiling look.
- U-values around 1.2 W/m²K.
- Re-glazeable designs (Korniche) for long-term flexibility.
- Pre-glazed modules that simplify installation and detailing.
They integrate effortlessly with warm-roof or cold-roof assemblies, making them ideal for modern single-storey designs.
Roof Lanterns
Lanterns like Atlas and Korniche transform orangeries and open-plan spaces with vertical light and height perception.
Key specifications:
- Spans up to 6m x 3m without tie bars.
- Fully thermally broken aluminium structure.
- Integrated drainage channels for long-term performance.
- Self-cleaning and solar-control glazing options.
Architectural role:
Roof lights deliver subtle illumination. Roof lanterns deliver spatial drama. Both expand the designer’s toolkit beyond the vertical plane.
From Aesthetic Harmony to Technical Continuity
What makes integrated glazing systems so valuable to architects is not just their variety — it’s their coherence.
The same design language can flow across an entire elevation:
- Consistent sightlines between doors and windows.
- Matching frame colours and finishes.
- Uniform thermal performance across the building envelope.
- Shared hardware tones and detailing.
This continuity matters, because design harmony isn’t just visual — it’s structural, regulatory, and experiential. It’s what turns a collection of openings into architecture.
Compliance and Performance: The Backbone of Modern Design
Design flair is meaningless without compliance.
The Trade Village range covers every base a specifier needs for Part L and Document Q conformity.
Key Performance Summary:
| System Type | Typical U-Value | Material | Security | Compliance |
| Aluminium Windows (Smart, Cortizo) | 1.1–1.4 W/m²K | Thermally broken aluminium | PAS 24 | Part L, Document Q |
| uPVC Windows (Eurocell, Deceuninck) | 1.2–1.3 W/m²K | Multi-chambered uPVC | PAS 24 | Part L, Document Q |
| Bifold / Sliding Doors | 1.3–1.6 W/m²K | Aluminium | PAS 24 | Part L, Document Q |
| Roof Lights / Lanterns | 1.2–1.4 W/m²K | Aluminium + Glass | N/A (non-opening) | Part L |
That means you can design freely, knowing every product in the system family supports the thermal model.
Detailing Simplicity – A Win for the Architect and Builder Alike
Glazing should simplify detailing, not complicate it.
That’s why the systems offered through The Trade Village are engineered for clean integration with standard building elements:
- 75–150mm upstands for rooflights and lanterns.
- Standard cavity closers for aluminium windows.
- Adjustable thresholds for bifolds and sliders.
- Consistent gasket detailing across product families.
This consistency means fewer cross-sections to draw, fewer junctions to worry about, and less time redlining the contractor’s drawings.
Aesthetic Precision – Light, Line, and Proportion
Good architecture lives in proportion — the subtle rhythm between solid and void.
With modern glazing systems, you can now express that rhythm through:
- Sightline alignment between door mullions and window transoms.
- Frame depth control to suit wall build-ups.
- Colour harmony from RAL 7016 to Jet Black to bespoke tones.
- Material consistency across all apertures.
Whether your language is industrial minimalism, contemporary vernacular, or clean classicism, the Trade Village range gives you materials that obey your visual intent.
Collaboration: Where Specification Meets Installation
The relationship between architect, builder, and installer is strongest when they all speak the same language.
That’s what The Trade Village enables — a product ecosystem that’s as design-conscious as it is trade-friendly.
- Architects get consistent, specifiable systems with technical documentation.
- Builders get predictable lead times and straightforward installation.
- Installers get quality, support, and pricing that protect profit.
It’s the full circle of construction — design, delivery, and delight.
Sustainable Thinking – Longevity Over Novelty
Sustainability isn’t a buzzword; it’s a design responsibility.
The Trade Village glazing portfolio supports long-term performance through:
- Recyclable aluminium and uPVC materials.
- Low-maintenance finishes that extend lifecycle.
- Thermal performance that reduces operational energy use.
- Supply chains optimised for minimal waste and efficient logistics.
Designing sustainably isn’t about compromise — it’s about confidence that your materials will perform for decades.
