New Construction Glazing in Centennial, CO

What new construction glazing actually involves
New construction glazing is the installation of glass systems, frames, and hardware into a building during the construction phase, before tenants occupy the space. This differs from retrofit work: you're building the envelope from scratch, coordinating with structural steel, mechanical rough-ins, and exterior envelope trades. It includes framed storefront, curtain wall systems, entrances, interior glass partitions, and viewable wall assemblies. The glazier works from architectural drawings, structural calcs, and performance specs to ensure every piece of glass, frame, sealant, and thermal break meets code and the building's long-term performance requirements.
When you need new construction glazing
You engage a new construction glazier during the design and build phases of any commercial project: office buildings, mixed-use developments, retail centers, and industrial facilities that require framed glass. The general contractor or construction manager puts out a bid package that includes glazing scope, and the glazier either bids as a subcontractor or works under a design-build glazing arrangement where the glazier gets involved early to advise on material selection and constructability. Timing matters: glazing typically installs after the building envelope is weather-tight but before mechanical and interior work ramps up. Delays in ordering, material availability, or specification changes can compress schedules, so early communication with your glazing team prevents cost overruns and keeps the general trade schedule on track.
How Element13 approaches new construction glazing
Element13 frames new construction work around a clear handoff between design intent and field execution. The process starts with detailed review of architectural and structural drawings to confirm glass type, frame specifications, fastening methods, and sealant requirements. Our NACC Master-Certified glaziers then coordinate with the general contractor to stage material delivery, protect adjacent trades, and sequence installation to match the overall project timeline.
In-house fabrication and assembly is critical here. We build framing, test Insulated Glass Units (IGUs) for thermal and structural performance, apply low-E coatings if specified, and assemble thermal breaks, pressure plates, and warm-edge spacers before units reach the jobsite. This means fewer on-site variables, tighter quality control, and faster installation once crews are on the building.
Our dual-capability model, developed over decades of both new construction and service work, means we know exactly what fails in the field and what prevents it. We catch specification gaps during the bid phase, not during installation. If a detail isn't clear, we ask before we order glass, not after it's on-site.
Why specify Element13 for new construction work
We're signatory to the Glaziers Union Denver, which means our crews are union-trained and meet the apprenticeship standards set by the union and the industry. NACC Master-Certified glaziers on our team understand load calculations, structural silicone installation, air and water resistance testing, and the IBC codes that govern safety glazing. We hold DBE, EBE, and WMBE certification, which matters if your project requires minority or women-owned vendor participation.
Zero major safety incidents on record reflects how we run the job. Accountability isn't a phrase we use; it's how we schedule, communicate, and solve problems when they show up. General contractors and facility directors across Denver and Centennial know that when Element13 says material arrives Tuesday, it arrives Tuesday. When a spec question comes up, we document the answer and get agreement in writing before we proceed.
Our in-house air and water testing capability means we don't outsource final performance verification. We test Insulated Glass Units, pressure plates, and sealant bonds to ASTM standards before they leave our facility and again on-site after installation. If a window doesn't meet AAMA 501 or 502 ratings, we know it before the GC does.
Wind load requirements and structural performance
Wind load is the first structural question in any new construction glazing specification. Your building's architectural drawings include a wind pressure map or a structural engineer's calcs that specify the design wind load in pounds per square foot at different elevations and exposures. The glazier's job is to select glass thickness, frame depth, and fastening that will resist that load without deflection, seal failure, or breakage.
ASTM E1300 is the standard we use to calculate glass load resistance. It accounts for glass type (annealed, heat-strengthened, tempered), dimensions, support conditions, and duration of load. A 10-story office building in downtown Denver experiences higher wind pressures at the top floors than at the base, so the glazing specification often varies by elevation. We pull those requirements from the structural drawings and size each frame and glass assembly accordingly.
Frame depth, mullion size, and fastening intervals also contribute to wind load performance. A shallow frame works for low-pressure interior partitions but fails fast on the exterior perimeter of a building exposed to 110 mph wind gusts. That's where knowing the code and the building's exposure category prevents costly rework.
Safety glazing specification and compliance
IBC Section 2406 and the International Glazing Certification Council standards govern where safety glazing is required. Tempered or laminated glass is mandatory in entries, sidelites next to doors, low windows below 18 inches from the floor, and glass within 24 inches of doors or stairs. The reason is simple: if someone falls against or into the glass, annealed (standard) glass shatters into sharp shards. Tempered glass breaks into small pebbles. Laminated glass stays bonded to an interlayer and doesn't separate even if cracked.
Specification sheets list safety glazing by location. We review the set and confirm laminated or tempered schedules match the code and the architect's intent. Templating and CNC cutting happen in our facility so the edges are precise and ready for frame assembly without field modification. Mislabeling safety glass is a liability issue and a code violation, so we label every unit, photograph it, and maintain records throughout the job.
Testing requirements before installation
New construction glazing systems must pass air infiltration and water resistance testing to meet AAMA ratings. AAMA 501 is standard for most commercial framing; 502 is high-performance, and 503 is custom. These ratings come from ASTM E330/E330M (structural performance under wind load), ASTM C1394 (structural glazing inspection cycles), and ASTM C1521 (adhesion testing of structural silicone). Testing validates that the sealant bond between glass and frame will hold for the life of the building.
Element13 conducts air and water testing in-house using calibrated equipment. We pressurize test chambers, spray test windows with water per ASTM standards, and document pass or fail. If a seal fails, we disassemble, diagnose whether it's a material issue or application error, correct it, and retest. This happens before installation, not after, when corrections cost time and money.
On-site testing after installation confirms that field conditions match factory results. Temperature, humidity, curing time for sealants, and moisture in the building envelope all affect performance. We verify that conditions are right before we sign off and turn the building back to the GC.
Stick-built versus unitized construction methods
Stick-built glazing is assembled frame-by-frame, mullion-by-mullion on the jobsite. Vertical mullions, horizontal mullions, and glass are installed in sequence, with sealant applied in the field. This method is flexible: you can adjust dimensions on-site, work around structural tolerances, and phase installation if building progress slips. The tradeoff is that field sealant application is weather-dependent, more variable, and harder to control than factory assembly.
Unitized construction pre-assembles entire wall sections (typically 4 to 5 feet wide, two or three stories tall) in the factory. Glass, frame, sealant, and fasteners all go together before the unit ships. Installation becomes a bolt-together operation: hang the unit, connect it to adjacent units and the structure, and seal the joints. Unitized work compresses jobsite schedule, improves quality because factory conditions are controlled, and reduces weather delays. The downside is higher upfront engineering cost, less flexibility if structural conditions are out of tolerance, and longer lead times.
Element13 performs both methods. We evaluate the project schedule, budget, and building conditions to recommend the right approach. For phased projects or buildings with tight architectural details, stick-built makes sense. For high-rise, schedule-critical work, unitized is usually the call.
Drainage, flashing, and the building envelope
Glazing is part of the building envelope, and the building envelope only works if water doesn't get trapped. Every frame head, sill, jamb, and stack joint needs a drainage path. Water that enters the frame cavity must exit to the outside or down to the sill, never inward toward structure or mechanical cavities.
Flashing at the top of window frames and at intermediate horizontal joints directs water to weep holes (small openings in the sill) where it drains to the outside. Slab-edge heads, common in multi-story construction, require special attention because the concrete floor sits behind the glazing line and thermal bridging happens easily. Thermal breaks (polyamide or polyurethane isolators between the inside and outside frame members) reduce heat transfer, but they also create a ledge where water can sit if the drainage system isn't designed right.
We detail drainage during the specification phase and again during shop drawing review. Desiccant spacers in IGU cavities absorb residual moisture so that condensation doesn't form between panes on cold mornings. Argon gas fill in IGU cavities improves thermal performance by reducing convection.
Our design-assist involvement early in a project catches drainage problems before drawing sets are locked. That's when a conversation with the structural and MEP engineers prevents rework, water intrusion, and warranty calls later.

Frequently Asked Questions
Typical timeline is 12 to 16 weeks from contract to material ready for installation. This includes design review and shop drawing approval (2 to 3 weeks), material ordering and fabrication (6 to 8 weeks), and testing and quality verification (2 to 3 weeks). Installation time depends on scope and building sequence: a single-floor retrofit of a commercial space might be 2 to 4 weeks; a full building curtain wall can run 6 to 12 weeks. Compressed schedules are possible but require early specification lock and expedited material ordering, which can add cost. We build the schedule from the GC's critical path and work backward so we're ready when the building phase needs us.
Structural tolerances on commercial buildings are typically plus or minus 1 inch per story. We build frames to nominal dimensions and field-adjust with shims and gaskets. If tolerances exceed 1.5 inches, the adjustment becomes difficult and sealant joints get thin or overstuffed. We survey the opening before we start, photograph it, and get the GC to confirm acceptance of the as-found condition. If it's worse than spec, the structural contractor corrects it before we proceed. This is not a glazier problem, but we flag it early so nobody's surprised.
Yes. We work with design-build glazing teams and general contractors to review specifications, advise on material selection, and estimate fabrication and installation costs before the project is bid. Early involvement means we catch constructability issues, suggest value engineering where glass or frame can be optimized without cutting performance, and confirm lead times for long-lead items. This reduces change orders and keeps schedules tight.
We back installation and fabrication workmanship for the duration of the project warranty, typically one year. Insulated Glass Units carry a separate manufacturer's warranty (often 10 years) against seal failure and seal-related condensation. We document everything: shop drawings, test reports, installation photos, and final sign-off. If a failure occurs, we diagnose it and repair it. If it's a manufacturing defect, we coordinate with the glass supplier for replacement. Warranty-phase work is part of how we operate; we follow projects through closeout and address any snags before the GC releases us.
No. Interior glass and partitions can be installed while the building envelope is still open, but exterior glazing requires the structure to be weather-tight and the frame opening to be clean and dry. Water ingress during fabrication or installation will ruin sealant bonds and create warranty issues immediately. We work closely with the GC to confirm the building is dry and ready before we mobilize crews. If the schedule slips, we wait. Rushing leads to problems.
Change orders. Once glass is cut and framing is fabricated, changes are expensive. That's why we get detailed specifications locked before we order, and that's why design-assist conversations up front save money. If a window type or size changes, we absorb the engineering review; the GC absorbs the material cost and schedule impact. We document every change and get written approval from the GC and architect before we proceed. This protects everybody.

When Glass Door Problems Can't Wait Contact Element13
Your building's glass front entrance doors handle hundreds of entries daily. When they fail, have cracked glass, broken closers, or hardware that won't engage, it's not just inconvenient, it's a security risk. Property managers and general contractors know that entrance problems reflect poorly on the entire building and create liability concerns.
