Everest 30 000 curtain wall systems for commercial elevations
Curtain wall is a glazed envelope carried on its own framing grid, hung from or spanning across the building's floor structure rather than sitting between slabs. It is the system of choice where an elevation reads as continuous glass from grade to parapet. The 30 000 family is the curtain-wall line within the Everest range.
Everest architectural aluminum systems for projects in Colorado, New York and California — product selection, estimating and project coordination through Gloria Glass, with Denver, New York City and Los Angeles as the principal target markets.
Who this is for
- Architects designing continuous glazed elevations on commercial buildings
- Developers pricing an envelope package during design development
- General contractors comparing envelope approaches and their sequencing consequences
- Glazing contractors seeking a system to price a bid package against
Common project applications
- Multi-storey commercial elevations with continuous vertical glazing
- Office building facades where floor lines are expressed with spandrel panels
- Mixed-use podium and tower elevations
- Atria, lobbies and double-height entrance volumes
- Institutional buildings where the envelope is a primary design element
Curtain wall, window wall and storefront are not interchangeable
The three systems can produce similar elevations and behave very differently. Curtain wall passes continuously in front of the floor slabs and is anchored back to the structure, so it can express a facade as an unbroken plane and must accommodate inter-storey movement. Window wall sits between the slabs, floor by floor, which simplifies erection and changes how movement, firestopping and water management are handled. Storefront is a non-load-bearing framing system generally used at grade for one or two storeys.
Choosing between them is an early design decision with consequences for structure, sequencing, cost and trade responsibility. Our comparison guide sets the three out side by side.
Stick-built versus unitised
Curtain wall is erected either as sticks — mullions and horizontals assembled and glazed in place — or as unitised panels fabricated in a shop and hung as complete units. Stick systems are more forgiving of field variation and typically suit lower buildings and smaller areas. Unitised systems move labour into a controlled environment, close the building faster and demand far tighter dimensional control from the structure.
Which one a project should use is decided by height, area, programme, site constraint and the erector's capability, not by preference. It is worth resolving before the envelope is priced, because the two produce very different numbers.
What we are and are not claiming here
This page describes a manufacturer system family that Gloria Glass is preparing to represent, with product selection, estimating and project coordination available through us. It does not assert engineering services, code approval, certification, tested performance values or delivery commitments. Those are established per project with the manufacturer and the project's design professionals.
What we need to prepare a budget
- Elevation drawings with overall glazed areas and floor-to-floor dimensions
- Building height, number of storeys and exposure
- The intended grid: typical bay width, mullion spacing and spandrel arrangement
- Vision and spandrel proportions, and the intended spandrel treatment
- Any operable vents, doors or louvres within the wall
- Structural framing type and how the anchors are expected to attach
- Programme: when the envelope needs to be closed in
Supply only or coordinated installation
Curtain wall is a system supply and coordination scope. Erection is normally performed by a glazing contractor with the equipment and crews for facade work, and we support that with product selection, estimating input and project coordination. Where a project needs a design-assist arrangement, the responsibilities of the design team, the engineer of record and the installer are defined at the outset.
Glazing, hardware and finish coordination
- Anchorage into the primary structure is engineered for the specific building; it is not a catalogue selection.
- Movement — thermal, live load, inter-storey drift — is accommodated by the system design and has to be reconciled with the structural engineer's numbers.
- Glazing makeup, spandrel construction and any back-pan or insulation build-up are coordinated as one assembly.
- Firestopping at the slab edge is a separate, coordinated scope that interfaces directly with the wall.
- Finish, colour and any dual-finish requirement are confirmed with the design team before release.
What must be verified before specification
Nothing on this page is a commitment about a specific project. Each item below is confirmed for the project in front of us before anything is specified or ordered.
- Structural attachment concept confirmed with the project's structural engineer
- Any engineering, testing, certification or documentation the project or jurisdiction requires
- Movement and drift criteria issued by the design team
- Glazing makeup and spandrel construction against what the family supports
- Availability of the family and finishes for the project's programme
- Site logistics: crane access, hoisting, staging and storage
Availability, final specifications, certification, engineering requirements, glazing, finish, delivery and project suitability are confirmed for each project.
Documented Everest product series
This page covers the general approach. The series pages below carry the manufacturer catalog data for the specific Everest families that apply here.
Project regions
Gloria Glass works on projects in Colorado, New York and California, with Denver, New York City and Los Angeles as its principal target markets. Its verified principal office is in Littleton, Colorado; there is no office, showroom, warehouse or inventory in New York or California.
Denver & Colorado
Front Range projects: altitude and solar exposure, diurnal temperature swing, wind and snow detailing at sills and thresholds.
Region pageNew York City
Dense urban work: building access and hoisting, freight and lobby restrictions, occupied-building sequencing and unit-size limits.
Region pageLos Angeles
Indoor–outdoor architecture: wide sliding openings, flush thresholds, coastal exposure and finish durability.
