Home / Products / High Performance Glass / Solar Control

Eastman XIR® Laminated products for solar control encapsulate “heat rejecting” film between two layers of Polyvinyl Butyral (PVB) and glass. The solar control product has a low-reflectance appearance. The film allows greater than 70% visible light transmittance while reflecting ~50% of the invisible heat. Glazed monolithically or combined into sealed insulating glass units, XIR film can be laminated with annealed, heat strengthened, or tempered clear glass, or combined with tinted PVB and tinted glass.

XIR Laminated glass improves monolithic laminated glass solar control performance by almost 50% with minimal impact on view and aesthetics. XIR laminated glass enables designers to create solar control solutions incorporating curved glass and enhances the performance of point fixed applications.

Solar Control Applications
Skylights, solariums, large glass facades, panoramic views, control towers, sports complexes, libraries/museums, medical facilities, point-fixed glazing, storefronts, and atriums

XIR Laminated Monolithic
XIR Laminated Monolithic can be used in vertical, sloped, or overhead glazing applications. From curtain wall (captured or structurally glazed) to monumental skylights, this technology offers expanded choices of energy-efficient glazing. XIR Laminated Monolithic can be fabricated in nearly all flat or architecturally curved configurations. By using tinted glass as the inner lite, the desire for solar performance (daylighting and SHGC ratio) can be adjusted to meet your specifications.

Solar Control Benefits

72% light transmission – improves day lighting
Solar Heat Gain Coefficient (SHGC) as low as 0.41 w/clear glass–
lower HVAC system and operating costs, increased comfort
8% visible reflectance – improves transparency
Blocks 99.5% UV rays – reduces interior fading
Uniform appearance over both flat and curved surfaces –
not possible with coated glass
Reduces outdoor noise

XIR Laminated IGU
A pane of XIR laminated glass and a second pane of glass are bonded by a spacer and separated by a sealed air space. While selectively blocking UV and near-IR, an XIR laminated IGU also acts as an insulator that provides comfortable temperatures in both summer and winter.

Solar Control Benefits

High neutrality – maximum clarity
60% light transmission – improves day lighting
Solar Heat Gain Coefficient (SHGC) as low as 0.30 w/clear glass-
lower HVAC system and operating costs, increased comfort
12% visible reflectance – lower glare & higher visibility
Low heat absorption – can eliminate costly tempering
U-value as low as 0.35 – high energy savings
Uniform appearance over both flat and curved surfaces
