Commercial Impact Windows
Impact glazing for storefronts, offices, and condo buildings, engineered, permitted, and installed by our own crews.
Commercial impact windows are engineered glazing systems that keep storefronts, offices, and multi-unit buildings sealed through hurricane winds and flying debris. Every project includes signed and sealed engineering, product approvals matched to the wind load, and phased installation scheduled so the business keeps operating. Small storefronts finish in days on site; larger properties are phased by elevation.
Storefronts, Offices, Condo Towers
Properties We Protect
Commercial glazing fails differently than residential glazing, and it costs more when it does. A blown-out storefront does not just let the storm in; it closes the business until the glass, the inventory, and often the interior are replaced. We install commercial impact windows across the property types where that math is most punishing: retail storefronts and restaurants with large glass frontage, professional and medical offices that cannot lose operating days, high-rise and mid-rise condo towers where wind pressure climbs with every floor, HOA buildings standardizing windows across dozens of units, and mixed-use buildings where one unprotected elevation exposes every tenant behind it.
Property managers and association boards get the same working model on every project: one point of contact, engineering and permitting handled in-house, certificates of insurance issued before work starts, and a schedule written around the building's hours rather than ours.
Specified Opening by Opening
Glazing Systems Built for Commercial Openings
Storefront Systems
Aluminum-framed impact storefront glazing for retail frontage and lobbies, with entrance doors integrated into the same engineered assembly, including panic hardware and ADA threshold options where the occupancy requires them.
Fixed Lites & Picture Windows
The largest glass spans on the building, specified with laminated impact glass and design pressures matched to their size.
Horizontal Rollers & Single-Hung Windows
The workhorse operable units for offices and condo buildings, in tested impact-rated series.
Casement & Awning Windows
Compression-sealed operables for upper floors and weather walls, where sealing performance matters most.
Every assembly carries a Florida Product Approval or Miami-Dade NOA, and glass packages scale from clear laminated to Low-E and tinted commercial glazing that cuts solar load across a full glass elevation. Where a building needs something beyond window systems, curtain wall or specialty glazing, we scope it during the site assessment and bring the right engineering partner.
Engineering Before Catalogs
Wind Load Rises With the Building
Wind speed increases with height, and the building code prices that in: design pressures climb with each floor, corner zones take higher loads than field zones, and exposure category changes the math again for open and coastal sites. Above roughly six stories, sliding doors also need taller thresholds to hit the water and design pressure ratings the code demands at elevation, and access logistics like swing stages get planned in the site assessment rather than discovered on install day. This is why a commercial impact window project starts with engineering rather than a catalog. Site-specific wind load calculations set the design pressure each opening must meet, the building's Risk Category tightens the requirements again for schools, medical facilities, and other higher-occupancy uses, signed and sealed drawings go to the building department, and the product approvals for each assembly are matched opening by opening. One distinction worth knowing when you review those approvals: a Miami-Dade NOA is valid anywhere in Florida, while a Florida Product Approval alone is not accepted inside the High-Velocity Hurricane Zone, so the certification on the quote should match where the building actually stands.
The paperwork is not a formality. Commercial inspectors check the installed assembly against the approval documents, anchor schedule included, and a mismatch stops the job. Our crews install to the engineering, and the closeout package your property file keeps includes every approval, calculation, and inspection record. When you compare commercial glazing contractors, ask each one for the signed and sealed drawings and the approval numbers on the exact assemblies quoted; that paperwork, not the pitch, is what the inspector checks.
Tenant-in-Place by Default
Installation Scheduled Around Business Hours
Commercial window installation succeeds or fails on scheduling, and commercial impact window replacement in an occupied building is a tenant-in-place operation, so every project runs through four steps written around the building's hours:
- Site Assessment
We measure every opening, document elevations and exposure, review tenant hours and access constraints, and deliver a written scope with a phasing plan.
- Engineering and Permitting
Wind load calculations, signed and sealed drawings, and the permit package typically take one to two weeks to produce, and municipal review of a commercial permit adds two to four more; commercial glazing manufacturing runs six to twelve weeks depending on the system.
- Phased Installation
Work proceeds elevation by elevation or suite by suite. Storefronts are often completed in one to three days on site, with after-hours and weekend slots for tenants that cannot close. Openings are weather-sealed at the end of every shift, never left exposed overnight.
- Inspection and Closeout
The building inspector verifies each phase against the drawings. We deliver the closeout package, register warranties, and walk the property with your manager or board.
Most commercial projects run eight to sixteen weeks from signed contract to final inspection, with manufacturing lead time the largest variable.
Impact Glazing vs Security Film: What Actually Meets Code
| Dimension | Commercial Impact Glazing | Security Window Film |
|---|---|---|
| Code opening protection | Yes; tested assembly with product approval | No; film is not approved opening protection |
| Debris impact | Glass and frame tested together to large-missile standards | Reduces shard scatter only; frame unchanged |
| Forced entry | Laminated glass plus engineered anchoring resists smash-and-grab | Delays entry briefly |
| Service life | Decades, with warranty | Degrades in sun; peeling and bubbling within years |
| Inspection outcome | Passes as opening protection | Fails as opening protection |
Film gets sold to businesses as the fast fix, and it does reduce flying glass. What it cannot do is turn an unrated storefront into code-compliant opening protection, and it adds nothing to the frame, which is where wind failure starts. Buildings that need protection on a budget phase the glazing by elevation instead.
The Year-Round Business Case
Why Owners and Associations Upgrade
The storm case makes the decision, and the year-round returns justify the timing. Impact glazing qualifies as opening protection for wind mitigation purposes, which commercial property insurers recognize in their rating of the building, and the documentation from our closeout package is what the insurance inspection wants to see. Tenants and staff stay protected without anyone deploying shutters across a strip of storefronts at midnight before landfall; on a building with dozens of openings that may be unstaffed when a storm track shifts overnight, deployment risk is the quiet failure mode, and glazing that is always in its protected state removes it. Deployed shutters also black out the storefronts insurers and tenants most want visible. Laminated glass resists the smash-and-grab break-ins that target retail glass. The laminated glazing's higher STC rating also quiets offices that face busy arterials, a difference tenants notice the week the units go in. And on a full glass elevation, Low-E commercial glazing measurably cuts the cooling load the HVAC plant carries through the long season.
For condo and HOA boards, standardization is its own return: one engineering package, one approved product series, one warranty structure, and a building that presents uniformly instead of unit-by-unit patchwork.
