Solar controller COOL-LITE® KS 138 II

Selective solar-control coating with silver aesthetic

Product description
COOL-LITE® KS 138 II combines selective solar protection with a silver reflective appearance to deliver controlled solar transmission and a distinctive façade look. The product contributes to building energy efficiency and occupant comfort while offering architecturally desirable external reflections. COOL-LITE® KS 138 II is a to-be-tempered product and can be combined with other Saint-Gobain Glass solutions for enhanced thermal, acoustic or safety performance.

Benefits & applications
The silver reflective finish allows the product to blend into urban contexts or to create contrasting façades where required.

• Aesthetic: Silver reflective outer appearance to integrate or differentiate façades.
• Solar control: Limits transmitted solar heat to approximately one quarter, supporting occupant comfort and building energy efficiency.

Suitable for all types of façades, COOL-LITE® KS 138 II is intended for non-residential buildings (offices, retail, hotels, restaurants) as well as residential applications where a reflective silver aesthetic is required.

Appearance
Transmission is neutral with silver reflections visible from the exterior, providing a consistent façade aspect.
