The Panelite ClearShade insulating glass unit was developed for exterior glazing applications using a tubular honeycomb core with patented polymer technology that offers superior shading performance. In addition to the benefits of visual privacy and a Visible Light Transmittance of up to 50%, the ClearShade IGU achieves a Solar Heat Gain Coefficient of .18 at midday, approximately 75% lower that that of other insulating glass units without the need for tinted, reflective or specialty glass. This dramatically reduces climate control requirements and results in significant energy savings over the life of the building.
The ClearShade IGU may be customized to meet a broad range of performance and aesthetic requirements.

See chart in catalog for comparative thermal performance of standard unit. For increased insulating properties, Panelite can provide low-e coatings and/or argon filled units.
STC Rating (Acoustical): 31
While the standard ClearShade IGU already provides an excellent sound barrier, specified STC requirements can be met by adjusting the glass composition and airspace/core ratio.
Class A, non-combustible
Up to hurricane force wind-load requirements may be met using specifically designed glass composition
Developed, manufactured, and tested in accordance with IGCC and ISO 9001:2000 specifications, the ClearShade IGU is certified for both exterior and interior applications. A dual-seal construction, IGCC certified and CBA rated, provides excellent resistance to MVT (moisture vapor transmittance) and to UV degradation. All glass used in Panelite IGU fabrication is tested and certified per ASTM1036 [float glass], ASTM 1048 [heat treated, tempered glass] and SGCC (heat-treated glass),
Panelite IGU’s are compatible with most commercially available storefront and curtainwall systems
The Panelite ClearShade IGU carries a 10-year limited liability warranty. Please inquire regarding project-specific technical requirements.
