Pioneering Sustainable Glazing with IQ Radiant Heated Glass and Guardian Nexa?

In the pursuit of environmental sustainability, Guardian Glass has introduced Guardian Nexa?, a lower-carbon float glass, to the European market following successful pilot production. Guardian Nexa represents a significant step forward in reducing the embodied carbon of building materials while maintaining high-performance standards. Designed for versatility, Nexa can be integrated into a range of Guardian products, including the SunGuard? and ClimaGuard? glass ranges, making it ideal for high-performance facades across diverse building applications.

Guardian Nexa brings "Lower Carbon, Same Great Performance" to the forefront of glass innovation, offering sustainability without compromise. The Nexa glass base can be paired with Guardian’s high-performance coatings, like Guardian SunGuard? and ClimaGuard?, which IQ Radiant Glass uses in its electrically heated glass systems. Together, these coatings and Nexa’s lower-carbon footprint help improve energy efficiency throughout a building’s life cycle while enhancing other critical properties. For instance, when Nexa glass is laminated, it not only lowers embodied carbon but also enhances security and sound reduction—two essential qualities for modern, energy-conscious buildings.

Integrating Guardian Nexa with IQ Radiant Heated Glass

IQ Radiant Glass is embracing this sustainable advancement by incorporating Guardian Nexa? as a base material in its high-performance heated glass systems. This integration allows IQ Radiant Glass to deliver an eco-friendly solution across its applications—from luxury residences and commercial facades to historic renovations—while furthering carbon reduction efforts. With Guardian Nexa, IQ Radiant Heated Glass elevates the sustainability profile of its product line without compromising the essential qualities that define its brand: superior thermal comfort, condensation control, and architectural versatility.

Commitment to Environmental Stewardship in Heated Glass Fabrication

IQ Radiant Glass has always prioritized sustainable sourcing and energy efficiency. By integrating Guardian Nexa? into its radiant heated glass products, IQ Radiant Glass delivers a more environmentally conscious heating solution for buildings, supporting both new construction and historic preservation projects. The inclusion of Guardian’s SunGuard? and ClimaGuard? coatings enhances IQ Radiant Glass’s commitment to energy-efficient performance by reducing heat loss, enhancing occupant comfort, and significantly improving sound insulation.

In addition, IQ Radiant Heated Glass allows for lower ambient room temperatures by delivering targeted warmth through the glass, further contributing to energy savings. The result is a glazing system that actively reduces a building’s carbon footprint while delivering enhanced comfort.

Advancing Transparency with Environmental Product Declarations

Guardian Glass is committed to transparency in its environmental practices. An Environmental Product Declaration (EPD) for Guardian Nexa is under development and will be available in Q2 2024, offering detailed environmental data. IQ Radiant Glass supports this transparency and views the EPD as an opportunity to bolster client trust and accountability in sustainable building practices.
