Recognizing the value unitization has brought to the construction industry, MG McGrath has developed a way to apply this approach across a wider variety of projects including low-rise and mid-rise buildings. Unitized systems reduce risk, speed up the project schedule, improve performance, and minimize waste. We have a rich history designing, fabricating and installing glass+ and metals+ systems and leverage that expertise when deciding when to deploy stick-built vs unitized systems. Our unitized wall systems are fabricated, assembled, and glazed in our controlled shop thus minimizing the time our crews spend in unpredictable field conditions for higher levels of safety and quality.

UNITIZED GLASS+ CURTAIN WALL SYSTEM
GLASS+
The MG Unitized Glass Curtain Wall system combines the cost control of standard glass curtain wall with the schedule advantages and precision of unitization. Our system is adaptable enough to meet modern design concepts, and responsive enough to be tailor-made to meet your projects performance and aesthetic requirements. In addition, unitizing gives us better control over the supply chain to adhere to the industry’s tight schedule demands.
Whether you are looking for an SSG butt-glazed curtain wall or a captured one with decorative mullion caps, you can feel confident knowing our MGU-8 Unitized Glass System has been tested to meet a wide range of applications. Engineered with performance built-in, our system meets the peak standards for air infiltration, water infiltration, and structural integrity. Our pre-glazed unitized curtain wall is factory assembled for elevated quality control and safety with the added benefit of year-round building erection.
Our MGU-8 Glass System was Tested and Passed the Following North American Performance Testing Standards

UNITIZED METALS+ SYSTEMS
METALS+
In addition to unitized glass curtain wall, MG McGrath has extensive experience delivering many other types of unitized façade materials such as metal, composite, and terra cotta.
Traditional full enclosure assemblies, rainscreen cladding, and larger sections of scrim, can all be customized in a unitized system that meets the schedule and performance of your project.

UNITIZED COMBO SYSTEMS
GLASS+ AND METALS+ IN ONE SYSTEM
We also have the capabilities to combine our Glass+ and Metals+ systems into one unitized combo system making fabrication and installation even faster and more versatile.
Glass and metal sheathing are glazed into our unitized curtain wall chassis with insulation, girts, and rainscreen panels applied to create a combo system that is high-performing and flexible to accommodate a wide range of aesthetics.
The advantage of using an MG McGrath unitized system is having an industry-leading, single-source option for your façade needs. We provide unmatched opportunities to have metals+ and glass+ combined in one unitized system fully fabricated and installed by our team.
