Guardian 275®

Guardian 275® translucent wall systems provide a wide range of color, thermal performance and specialty application options.

Guardian 275®

Guardian 275® translucent panel wall systems are the most versatile in our product line. From the highest level of performance options to numerous specialty configurations and industry-long warranties, Guardian 275® systems are the perfect custom daylighting choice.

Like our other translucent panel systems, Guardian 275® wall systems feature a lightweight sandwich panel design, and come standard with concealed fasteners, an innovative “snap and capture” detail that provides rapid field installation and secure holding power, and  unsurpassed protection against water and air infiltration by using only EPDM gasketing and long-lasting high-performance sealants. No other translucent panel systems offers this much at no extra charge. Guardian 275® is also available with a variety of insulation options, as well as a 4” panel option, enhancing thermal performance.

In design, versatility is key. And while Guardian 275® offers glare-free, diffuse natural light to illuminate interior spaces, it also gives you the options to make your design a reality. From blast and hurricane protection systems to mixed glazed systems that combine fixed and/or operable glass to our Translucent Adapter Panel that allows for easy integration of our 2.75” systems into existing 1” curtainwall framing, we have a daylighting solution that’s right for your needs and budget. We also offer pre-assembled options for select smaller sized units, making installation quick and easy. (Contact Major at 888-759-2678 for more details.)

Whether it’s a simple clerestory or a complex curved wall, Guardian 275® is a high-performance, cost-effective, and lightweight solution.
