Commercial Storefront Glass

Kawneer Trifab 451 and 451T are the most common storefront systems in NJ commercial buildings built since 1990. 1-3/4" or 2" frame depth, center-set or front-set glazing pocket, multiple thermal break options. Parts pipeline is mature — we get gaskets, glazing tape, sweeps, and weep covers from local Kawneer distributors within 1-2 days. We default to Kawneer 451 for new commercial storefront work because the system's flexibility, the local parts availability, and the proven 30+ year service life justify the slight cost premium over YKK or EFCO equivalents.

YKK AP YES 45 and YES 60 are the value-tier and mid-tier alternatives. Slightly less expensive than Kawneer at install, comparable thermal performance, parts pipeline through YKK distributors in central NJ. We see a lot of YES Series on 1990s-2010s strip retail and second-generation office buildings. Repair-friendly system but the glazing pocket gaskets are not interchangeable with Kawneer — wrong gaskets cause leaks within a season.

EFCO 433 and 451 are the workhorse mid-Atlantic storefront systems for high-rise and Class A office buildings. Heavier frame profiles, better wind-load ratings, more thermal break options. Common in Newark, Jersey City, and Hoboken Class A buildings from the 1980s-90s. Parts pipeline is less convenient than Kawneer or YKK in NJ — we order through EFCO direct with 3-5 day lead time on gaskets and trim.

US Aluminum (now part of CRL) — Series 451, 351 — is the budget option common in 1980s strip retail. System is functional but parts availability is hit-or-miss for older configurations. We often replace US Aluminum frames rather than repair them when the original system is more than 25 years old.

Storefront doors in NJ commercial buildings must comply with ADA Title III as enforced by the U.S. Department of Justice and adopted in IBC Chapter 11. Key requirements: 32" minimum clear width when door is open 90° (typically requires a 36" nominal door); maximum 5 lbf opening force for interior doors and exterior doors are limited to whatever the closer manufacturer can demonstrate (typically 8-10 lbf for exterior storefronts, which is allowable under ADA's exception for exterior doors); door closer adjusted so the door takes minimum 5 seconds to close from 90° to 12°; thresholds maximum 1/2" with beveled transition.

Storefront door hardware: ADA requires lever handles, push bars, or push plates — no round knobs. Operating height 34-48" off the floor. We replace non-compliant hardware as part of any storefront door reglaze or replacement to bring the assembly to current compliance at the same time as the glass work.

Automatic door operators (low-energy or full-power) are required on entrances to many public-accommodation buildings under ADA, and required by local ordinance in some NJ jurisdictions for new commercial construction. We install and service Stanley Magic-Door, Horton, Besam, and Record operators in coordination with our storefront door work.

Retail and restaurant tenants can't operate with a boarded storefront — every hour the board-up stays up is revenue lost. We do roughly 40% of our storefront reglaze work outside business hours: nights, weekends, holidays. Coordination starts with the property manager (who owns the building envelope and contracts the work), the tenant (who owns the operating schedule), and where applicable the landlord's insurance carrier (who's paying for the work after a covered claim).

Typical after-hours storefront reglaze: 6 PM Friday close, board-up removed by 7 PM, new glass installed by 11 PM, sealants curing overnight, weep verification and final cleanup by 6 AM Saturday, ready for opening at 10 AM. Premium pricing applies (typically 40-60% over standard daytime rates) and is built into the quote.

Mall and shopping-center tenants have additional layers: mall security badging, freight elevator scheduling, common-area floor protection, mall management notification. We carry the OCIP coverage and the W-9 documentation that mall property managers (Westfield, Simon, Brookfield) require, and we maintain pre-approved contractor status with several NJ mall operators.

Glazing gasket failure — the EPDM gaskets that seal the glass to the frame harden and lose compression. Water finds the path past them and ends up in the building. Repair: pull old gaskets, clean glazing pocket, install new gaskets matched to the frame system. 30-60 minutes per opening if access is straightforward.

Weep system blockage — drainage holes at the sill clog with paint, sealant overspray, or debris. Water that's supposed to drain back out pools in the sill track and migrates into the building. Repair: clear weeps with compressed air and pipe cleaners, verify drainage with a water test, re-install weep covers.

Door operator failure — closers leak fluid, lose pressure, fail to close the door. Door alignment goes out, latch doesn't engage, sweep no longer seals. Repair: rebuild or replace closer (LCN, Sargent, Norton — we carry the common models), re-align door, replace sweep and weatherstrip.

Frame corrosion — anodized aluminum frames in coastal locations or in regularly wet conditions develop pitting corrosion that eventually compromises the structural integrity of the frame. Repair: depends on extent. Minor pitting can be cleaned and sealed; deep corrosion requires frame member replacement.

Broken or chipped tempered glass — typically from shopping cart impact, vandalism, or stress from poorly seated gaskets. Reglaze with matching tempered glass, typically same-day or next-day for stocked sizes.
