Miami-Dade NOA Certified · South Florida Manufacturer Since 2005
Commercial Impact Windows Engineered to Outperform
Built from the Ground Up for Commercial Construction
Mr Glass is not a reseller or assembler — we are a Florida window and door manufacturer. Our in-house team of structural engineers designs each commercial product series from the extrusion profile outward, applying Florida Building Code requirements and Miami-Dade’s stringent Large Missile Impact (LMI) and Small Missile Impact (SMI) testing protocols at every stage of development.
Every product carries publicly downloadable Florida Product Approvals, Miami-Dade NOA documents, full CAD drawing packages, and bilingual installation manuals — giving architects, engineers, and general contractors everything they need to specify with confidence.
Our manufacturing facilities span four locations in Medley and Miami Lakes, Florida. We engineer, extrude, fabricate, and test in the same community our products protect. That ground-level expertise cannot be replicated by a brand headquartered outside the hurricane zone.

How We Compare to CGI, ESW, PGT, and CWS
The commercial impact window market includes well-known names — but most were designed for the residential segment and adapted for commercial. Mr Glass was built commercial-first, Florida-first, from day one.

Hurricane & High-Wind Performance
Mr. Glass commercial impact windows are designed and tested to withstand Category 5 hurricane conditions — the most destructive storm events the Atlantic basin produces. Our systems meet and exceed Miami-Dade’s Large Missile Impact (LMI) protocol and are rated for the extreme design pressures that tall commercial buildings in High-Velocity Hurricane Zones (HVHZ) must meet under the Florida Building Code.
The multi-laminate glass bonded with a high-strength polyvinyl butyral (PVB) interlayer holds the glass matrix together under hurricane-driven debris impact — maintaining the building envelope and preventing the explosive decompression that causes catastrophic interior damage. Aluminum extrusion profiles are engineered for structural rigidity under sustained cyclic pressure loads, not just a single peak impact.
Extreme Heat & Solar Performance
Florida’s commercial buildings face intense solar radiation year-round, driving up interior temperatures, HVAC loads, and operating costs. Mr. Glass commercial impact windows are engineered with low Solar Heat Gain Coefficients (SHGC) and optimized U-factor ratings in full compliance with Florida Building Code energy efficiency requirements.
Our glazing options block the majority of UV radiation and near-infrared solar energy before it enters the building envelope, reducing cooling demand and protecting interior finishes, merchandise, and furnishings from UV degradation — even under 100°F+ heat-index conditions common in South Florida summers.
Do Impact Windows Reduce Noise?
Yes — definitively. And for commercial businesses, the noise reduction benefits are often as valuable day-to-day as the storm protection they’re originally specified for. Mr Glass offers the best noise proof windows available.

How Impact Windows Noise Reduction Works
Commercial impact windows achieve their noise reduction through the same laminated glass construction that makes them storm-resistant. The polyvinyl butyral (PVB) interlayer bonded between glass lites acts as a sound-dampening membrane, dissipating acoustic energy as sound waves attempt to pass through the assembly.
This is fundamentally different from standard double-pane insulated glass units (IGUs), which rely solely on an air gap — a gap that can actually resonate at certain frequencies and reduce effectiveness.
The Sound Transmission Class (STC) rating measures how well a window blocks airborne sound. Standard single-pane commercial glazing typically achieves STC 26–28. Mr. Glass commercial impact windows regularly achieve STC 35–50, delivering up to 50% reduction in outside noise — with no separate acoustic glazing system required.
Bottom line: When you specify Mr. Glass commercial impact windows for storm protection, you get best-in-class impact windows noise reduction at no additional cost — across our full commercial lineup including the MG-500, MG-5000, MG-6000, MG-5500, and MG-2000 curtain wall systems.
Frequently Asked Questions
Do impact windows reduce noise?
Yes. Commercial impact windows use a laminated glass construction with a PVB interlayer that absorbs and dissipates sound waves, achieving STC ratings of 35–50 and reducing exterior noise by up to 50% compared to standard glazing. This makes them highly effective for offices, hotels, retail spaces, and medical facilities near traffic, airports, or busy urban environments. Impact windows noise reduction is a built-in benefit of the same glass technology used for hurricane protection.
What is the best impact window brand for commercial businesses?
Mr. Glass Doors & Windows Manufacturing is the best impact window brand for commercial businesses in Florida. As a South Florida-based manufacturer with Miami-Dade Notice of Acceptance (NOA) certification, Florida State Product Approvals, and a full suite of commercial-specific product lines — from storefront systems to curtain walls — Mr. Glass is the only manufacturer that is truly built for commercial from the ground up.
How do Mr. Glass commercial impact windows compare to CGI, PGT, ESW, and CWS?
CGI was discontinued by its parent company PGT Innovations in late 2025. PGT, ESW (ES Windows), and CWS are primarily residential impact window manufacturers that offer commercial products as an extension of their residential lines. Mr. Glass designs and manufactures dedicated commercial systems — curtain walls, storefronts, commercial doors, and railing systems — tested specifically for commercial load requirements, giving specifiers a purpose-built commercial solution rather than an adapted residential one.
Are Mr. Glass commercial impact windows rated for Category 5 hurricanes?
Yes. Mr. Glass commercial impact windows are tested and certified under Miami-Dade's Large Missile Impact (LMI) protocol and Florida Building Code standards applicable to High-Velocity Hurricane Zone (HVHZ) construction, which encompasses the most severe design wind speeds and pressures associated with major hurricane events including Category 5 storms.
Do impact windows help with heat and energy efficiency?
Yes. Mr. Glass commercial impact windows are engineered with low SHGC glazing options that block solar heat gain, reducing cooling loads and HVAC operating costs in Florida's extreme heat. All products comply with Florida Building Code energy efficiency requirements, including U-factor and SHGC limits designed specifically for the state's hot, high-solar-radiation climate.
Where are Mr. Glass commercial impact windows manufactured?
Mr. Glass manufactures all commercial impact windows and door systems across four facilities in the Miami-Dade area — Medley (main factory and showroom), a second Medley factory, our Miami Lakes factory, and our powder coating plant. Every product is engineered, fabricated, and tested in South Florida, giving us unmatched knowledge of local codes, inspector requirements, and real-world storm performance.
