Commercial storefront systems in New Jersey.

Commercial storefront systems are aluminum-framed, non-load-bearing entrance and window assemblies installed in ground-floor commercial space. Architects, general contractors and building owners specify them because the framing controls thermal performance, sightline width and glass makeup at the most visible and most heavily used part of the building — and because entrance doors carry the code and ADA requirements the rest of the facade does not.

Comparison

American standard framing versus European slim-sightline systems.

American standard commercial storefront framing — American standard
Captured glass, applied stops, expressed framing grid

European slim-sightline commercial storefront framing — European slim-sightline
Narrow face widths, flush plane, glass-dominant elevation

Comparison of American standard storefront framing and European slim-sightline storefront systems
Criterion	American standard	European slim-sightline
Sightline / face width	Typically 2" to 2-1/2" face widths with applied stops; visible frame grid.	Narrow face widths, often 1-3/8" to 2", with flush exterior planes.
Thermal performance	Poured-and-debridged or polyamide thermal breaks; standard performance meets most NJ energy code paths.	Multi-chamber polyamide isolators and insulated pressure plates; higher U-factor and condensation resistance.
Glazing method	Captured glass with snap-on stops; field or shop glazed, 1" IGU typical.	Structural silicone or slim captured stops; accepts heavier and triple-glazed units.
Typical use case	Retail frontage, medical and office lobbies, flex and industrial entrances, fast-turn replacement.	Design-driven facades, high-performance envelopes, projects with strict U-factor or aesthetic targets.
Procurement	Broad domestic supply, short lead times, simple part replacement.	Longer lead times, tighter fabrication tolerances, imported or licensed profiles.
Aesthetic	Utilitarian, clearly expressed framing grid.	Minimal frame, glass-dominant elevation.

Scope

Factors we scope during proposal.

No storefront package is priced from square footage alone. These are the variables reviewed before a budget range or a lump-sum or time-and-material proposal is issued. If the existing framing stays and only the glass is failing, see commercial window replacement.

Linear footage and opening geometry

Total framed perimeter, number of intermediate verticals, corner and transom conditions, and head/sill anchorage all change fabrication and field hours before any glass is priced.

Glass type and thickness

Monolithic, insulated, laminated, tempered, low-E coating selection and spandrel or security glazing each carry different unit weight, handling method and lead time.

Thermal break requirement

Whether the energy code path, envelope commissioning or owner requirement calls for thermally broken framing determines the system family and the price tier of every profile.

Hardware integration

Closers, panic devices, automatic operators, electric strikes and access-control raceways all need to be coordinated into the door and frame before shop drawings are released.

Code and ADA compliance

Accessible opening force, maneuvering clearances, threshold height, glazing safety marking and egress hardware are reviewed against the current drawing set during scope review.

Site conditions and access

Occupied buildings, night or phased work, sidewalk protection, existing substrate condition and lift or scaffold requirements are scoped and stated explicitly in the proposal.

Fabrication & install

From approved drawings to a sealed, adjusted entrance.

01
Spec and plan review
Elevations, door and hardware schedules, glazing specifications and performance criteria are reviewed against the system families that actually satisfy them.
02
Field survey
On retrofit work, openings are measured, substrate and anchorage conditions verified, and existing sealant and flashing joints assessed before dimensions are released.
03
Shop drawings and submittals
Fabrication drawings, product data, finish samples and hardware submittals are issued for architect and GC review prior to release.
04
Fabrication
Framing is cut, machined and assembled to approved dimensions; doors are prepped for the specified hardware; glass is ordered against approved makeup.
05
Installation
Framing is set plumb, level and anchored to the approved detail, glass is set and gasketed, and doors are hung and adjusted to specified operating force.
06
Perimeter seal and closeout
Perimeter joints are backed and sealed, operation is verified, punch items are cleared, and warranty and maintenance documentation is issued.

FAQ

Storefront technical questions.

What is the difference between a storefront system and a curtain wall?+

Storefront is a non-load-bearing aluminum framing system installed between floors, typically at grade and generally limited to roughly one or two stories. Curtain wall spans continuously past the slab edge and is engineered to carry wind load back to the structure over multiple floors. Storefront is set inside the opening; curtain wall hangs in front of it.

Does a commercial storefront have to be thermally broken?+

Not in every case, but most conditioned commercial space in New Jersey now lands on an energy code path that requires thermally broken framing to meet the assembly U-factor. Non-thermal framing is still used for unconditioned vestibules, interior partitions and some canopy or flex-space conditions.

Can existing storefront framing be reused when only the glass has failed?+

Often, yes. If the framing is straight, the anchorage is sound and the pockets accept the replacement unit thickness, failed insulated glass units can be reglazed in place. When the framing is non-thermal, corroded or out of plumb, replacement of the full system is usually the better value over the life of the facade.

What glass thickness is typical in a commercial storefront?+

Standard is a 1" insulated glass unit — two lites of 1/4" glass with a 1/2" air or argon space and a low-E coating. Tempered or laminated lites are used where safety glazing, security, sound or hurricane-zone criteria apply, which changes unit weight and framing selection.

What ADA requirements affect storefront entrance doors?+

Accessible entrances are governed by maximum opening force, closer sweep and latch timing, hardware operable without tight grasping or twisting, threshold height limits, and clear maneuvering space at the push and pull sides. These are reviewed against the drawing set during scope review, since they usually decide the closer, operator and threshold selection.
