Product description
COOL-LITE® SKN 155 and SKN 155 II are selective solar-control coated glass solutions developed for high-performance façades. They combine high visible light transmission with reduced solar factor to balance daylight, thermal comfort and architectural neutrality, suitable for modern glazed buildings.

Benefits & applications
COOL-LITE® SKN 155 (II) delivers a balanced approach to daylighting and solar protection, supporting functional and aesthetic requirements.

• High daylight transmission (TL ≈ 50%) with strong solar protection (g-value ≈ 27%) for bright interiors and reduced cooling loads.
• Neutral exterior appearance and low reflection across viewing angles, suitable for large glazed façades in offices, commercial and premium residential projects.
• Available on PLANICLEAR®, DIAMANT® and ORAÉ® substrates in annealed and to-be-tempered versions, enabling varied glazing configurations.

Applications include:

• Offices
• Hospitals
• Schools
• Sports centres
• Retail stores
• Restaurants
• Large south- or west-facing glazing and bay windows
• Skylights and conservatory roofs

COOL-LITE® SKN 155 (II) is also available on ORAÉ® low-carbon glass. The product is covered by a verified Environmental Product Declaration (EPD) and holds Cradle to Cradle Certified® V4.0 Bronze. COOL-LITE® SKN 155 and 155 II succeed the European COOL-LITE® SKN 154 family with improved performance and refined aesthetics; previous references will be phased out.

Appearance
COOL-LITE® SKN 155 (II) provides colour neutrality across viewing angles.
