PPG and Pleotint jointly market self-tinting Suntuitive glass for dynamic window systems, which features a lightly tinted UV/sunlight-responsive, thermochromic interlayer that warms up and darkens in direct sunlight, but clears in indirect sunlight to allow light to pass into a building. This polyvinyl butyral (PVB) system responds to rising and cooling temperatures as the sun moves across the sky, lightening and darkening accordingly.
As part of a complete window system, Suntuitive glass helps manage a building’s ever-changing needs for passive solar gain, solar control and natural daylight transmittance. This adaptability can help lower the costs associated with heating, air-conditioning and artificial lighting, which together can represent up to 70 percent of a building’s total energy consumption.
The performance of Suntuitive glass is further enhanced when it’s combined in insulating glass units (IGUs) with high-performance solar control low-e glasses by PPG. In fact, IGUs made with Suntuitive glass can produce visible light transmittance (VLT) of up to 60 percent when clear and a solar heat gain coefficient (SHGC) as low as .11 when dark.
Suntuitive glass also provides amazing aesthetic and performance benefits when combined with any combination of PPG clear and tinted glasses for the exterior (No. 1) lite and high-performance Solarban® 60 glass or Solarban® 70XL glass for the insulating, interior (No. 3) lite.
Architects also may specify any one of PPG’s high-performance tinted glasses—nautically inspired blues and greens or Earth-toned bronzes and grays—as a base-state window color.
