Curtain Walls& Window Walls
Exterior glazing systems coordinated around the building structure, glass, framing, anchors, perimeter transitions, weather performance, movement, and architectural intent.
Two façade approaches. Different building interfaces.
NYC ALL GLASS supports qualifying curtain wall and window wall projects across New York City for general contractors, architects, developers, property managers, and building teams. Work may include new installation, glazing, replacement, renovation, and corrective scopes.
The system type must follow the approved project design. Curtain wall and window wall are not interchangeable labels; they relate differently to the floor slabs, exterior plane, anchors, perimeter conditions, drainage, movement, and interior construction.
Curtain Wall
A non-load-bearing exterior wall system typically attached to the building structure and positioned outside or across the floor-slab edges. Exact configuration depends on the specified system and project design.
Window Wall
An exterior glazing system commonly installed between floor slabs, with slab-edge, head, sill, interior closure, spandrel, and perimeter conditions coordinated at each level.
The grid follows the architecture and structure.
Mullion spacing, glass modules, anchors, entrances, corners, slab edges, spandrel zones, and transitions must be coordinated as one façade system.
Curtain Wall Systems
Architectural exterior glazing coordinated with the building structure, anchors, mullions, pressure systems, glass, perimeter, and adjacent construction.
Window Walls
Between-slab glazing systems coordinated at head, sill, jambs, slab edges, and interior closure conditions.
Custom Façade Conditions
Corners, transitions, entrances, canopies, operable elements, and special glass zones within the larger elevation.
Six layers shape performance.
The system must connect architectural intent to structural support, glass, drainage, thermal continuity, and perimeter construction.
Framing Grid
Mullions, horizontals, caps or structural silicone zones, frame depth, finish, modules, corners, transitions, and fabrication tolerances.
Glass & Spandrel
Insulated or other specified glass, vision zones, spandrel zones, coatings, frit, tint, opacity, heat treatment, safety requirements, and appearance.
Anchors & Structure
Slab edges, embeds, anchor locations, brackets, fasteners, tolerances, deflection, access, and project-specific structural criteria.
Air & Water Path
Pressure equalization where applicable, glazing seals, gaskets, weeps, sill conditions, end dams, joints, flashings, and perimeter sealants.
Thermal Continuity
Thermal breaks, insulated glass, spandrel and slab-edge zones, interior closures, condensation risk, perimeter insulation, and adjacent assemblies.
Project Interfaces
Entrances, operable windows, louvers, canopies, sunshades, parapets, roofs, fire-safing by responsible trades, interior finishes, and construction sequence.
The glass is only one layer of the exterior wall.
Façade performance depends on how the entire system handles wind, rain, temperature differences, building movement, fabrication tolerances, field installation, sealants, drainage, and transitions to adjacent construction.
Exterior glazing for active New York properties.
Curtain wall and window wall scopes vary by building height, use, façade geometry, access, exposure, occupancy, and construction sequence.
Office Buildings
Commercial façades, lobby zones, tenant floors, entrance integrations, and renovations.
Multifamily
Residential towers, apartment buildings, condominiums, amenity levels, and window wall systems.
Retail & Mixed Use
Street-level glazing, multi-story façades, storefront transitions, and mixed-use elevations.
Institutional
Educational, healthcare, civic, and other project-specific building-envelope scopes.
Hospitality
Hotels, restaurants, event properties, entrance zones, and architectural glass façades.
Replacement, reglazing, or broader system repair?
A failed glass unit, leak, damaged cap, or deteriorated sealant can be isolated—or it can signal a larger problem involving drainage, gaskets, pressure components, perimeter joints, anchors, movement, thermal conditions, or compatibility. Existing systems require investigation before repair scope is finalized.
From elevation review to completed façade.
Exterior glazing requires approved system information, verified field conditions, controlled fabrication, access planning, coordinated installation, and disciplined perimeter work.
Scope Review
Drawings, specifications, elevations, system type, project location, and schedule are reviewed.
Field Verification
Openings, slab edges, anchors, transitions, access, and existing conditions are checked.
System Coordination
Frames, glass, anchors, drainage, perimeter, finishes, and related trades are organized.
Preparation
Approved and verified information is used for glass, framing, panels, and components.
Installation
Systems are installed in the planned sequence with access equipment and site protection.
Final Review
Glass, framing, gaskets, sealants, drainage, alignment, finishes, and documented scope are reviewed.
