Stick-built describes the assembly method: vertical mullions and horizontal transoms (the facade’s aluminum skeleton) are installed on site member by member, then glazed panel by panel. The format adapts to field conditions and irregular grids more flexibly than factory-preassembled units, which suits renovation facades and custom elevations.
- Mullion profiles anchor to the structure and set the vertical rhythm.
- Transoms divide the grid horizontally at floor, spandrel and vent lines.
- Glazing infills, vision glass or opaque panels, seat into the grid with gaskets.
- Designer cover caps snap over the members, defining the facade’s visible line.
The MN 50 build-up resists weather while keeping sightlines slim, and its interchangeable cover caps give the architect creative control over how pronounced the grid reads, from flush minimalism to expressed structure.
Curtain Wall vs Storefront: What Separates the Two?
Curtain wall vs storefront is a question of height, load path and performance class, not appearance. Both are glazed aluminum facades; the engineering underneath differs.
| Criterion |
Curtain wall |
Storefront |
| Typical height |
Multi-story, spanning floor to floor |
Ground level, single story |
| Load behavior |
Hangs outside the slab edge, self-spanning |
Sits between floor and header |
| Weather strategy |
Pressure-managed, internally drained |
Perimeter-sealed |
| Thermal class |
Higher, engineered for full envelopes |
Standard, entry-zone duty |
| Typical role |
Building facades and elevations |
Entrances and retail frontage |
Vision Art Aluminium supplies both formats, so the split is made per elevation: curtain wall where the facade spans floors, storefront where a ground-level entrance needs glazed presence at storefront economics.
How Does Glass Curtain Wall Design Shape Daylight?
A glass curtain wall turns the facade into the building’s primary light fixture. Floor-to-floor vision glass pulls daylight deep into the plan, cutting artificial lighting load through the working day, and the slim MN 50 grid keeps the view ratio high: more curtain wall glass, less frame shadow.
Glazing selection tunes the physics. Low-E coatings manage solar gain against the elevation’s orientation, insulated units carry the thermal envelope, and opaque spandrel panels (the glazed bands concealing floor edges) keep the exterior reading as one continuous glass surface.
Which Projects Specify Aluminum Curtain Walls?
Aluminum curtain walls concentrate where daylight, presence and envelope performance meet: office and mixed-use facades, showrooms and dealerships whose product is the view inside, medical and institutional buildings needing daylight with sealed performance, and hospitality frontages where the elevation is the brand. In NJ and NY renovation markets, recladding an aging facade with a curtain wall system modernizes both the architecture and the energy envelope in one program.
Interior applications borrow the same logic: full-height glazed partitions on the curtain wall principle divide space without dividing light, an approach shared with the frameless office partition range.
Who Is the MN 50 Curtain Wall Right For?
Three project profiles align with the system. Commercial owners get a fully glazed, thermally engineered facade delivered through one seven-step accountable sequence. Architects get a stick-built grid with slim sightlines and designer cover caps that keep creative control over the elevation’s expression. Design-build teams get single-source integration of glass, framing and hardware, which converts facade coordination risk into a single supplier relationship.
Single-story entrance programs are storefront territory within the same range; the curtain wall earns its engineering where the facade spans floors and the elevation defines the building.
System configurations can change. Spans, thermal targets, finishes and cover cap options should be confirmed per elevation during technical detailing.
Frequently Asked Questions
What is a curtain wall on a building?
A curtain wall is a non-structural aluminum-and-glass skin hung on the building’s frame, carrying its own weight and wind load but no floor loads. It separates the weather envelope from the structure, which is what allows fully glazed, multi-story elevations with slim framing.
What is the difference between a curtain wall and a storefront?
A curtain wall spans multiple floors, hangs outside the slab edge and uses pressure-managed, internally drained weather design with higher thermal class. A storefront sits in single-story ground-floor openings with perimeter sealing, serving entrances and retail frontage at lighter engineering.
What is a stick-built curtain wall?
Stick-built means the facade is assembled on site member by member: mullions first, then transoms, then glazing and cover caps. The method adapts to field conditions and custom grids, which suits renovations and bespoke elevations like those built on the MN 50 system.
Are curtain walls energy efficient?
Engineered correctly, yes. The MN 50 build-up pairs thermally designed aluminum profiles with insulated Low-E glazing and internally drained weather management, so a fully glazed elevation performs as an insulated envelope. Orientation-specific glass selection tunes solar gain per facade.
Is a curtain wall structural?
No. The curtain wall carries only itself and the wind pressure on its surface; floors and roof loads stay in the building’s own frame. That separation is the format’s defining principle and the reason facades can be glass from ground to parapet.
