Solar control glass panel COOL-LITE® XTREME 61/29

laminatedfloattemperable

PRODUCT DESCRIPTION
COOL-LITE® XTREME 61/29 and 61/29 II are triple-silver solar control glass designed for architectural façades. They deliver medium–high visible transmission with a low solar factor, providing neutral colour rendering at all viewing angles and reduced external reflection for consistent appearance on large glazed elevations.

BENEFITS & APPLICATIONS

• Neutral aesthetic in transmission and in both internal and external reflection, supporting contemporary design trends for colour neutrality and transparency.
• Consistent outdoor appearance between annealed and to-be-tempered versions, enabling uniform façades.
• Energy efficiency: extreme selectivity reduces demand for artificial lighting, heating and cooling.
• Indoor comfort: high daylight transmission combined with effective solar control improves occupant comfort year-round.

Recommended applications include fully glazed façades where strong solar protection and refined aesthetics are required:

• Office buildings
• Healthcare facilities
• Educational buildings
• Commercial and residential façades

APPEARANCE
COOL-LITE® XTREME 61/29 and 61/29 II offer extreme colour neutrality at all viewing angles, low reflection and consistent colour reproduction, making them suitable for modern architectural glass façades.

TECHNICAL INFORMATION
RANGE / Substrates: PLANICLEAR® (clear glass); DIAMANT® (extra clear glass); ORAÉ® (low-carbon glass).
THICKNESS: 4 mm to 10 mm; to-be-tempered up to 12 mm.
SIZE: Standard jumbo 3.21 x 6.00 m. Standard stock sizes available. Overlength up to 18 m (to-be-tempered).

PROCESSING

• ANNEALED: available in annealed version.
• HEAT-TREATMENT: to-be-tempered version (suffix II). Delivered with EASYPRO® temporary surface protection. Tempering is required to achieve intended performance and appearance; compatible with Heat Soak Test.
• EDGE DELETION: edge deletion of the coating is compulsory prior to assembly.
• INSULATED GLAZING UNIT (IGU): must be assembled into an IGU with the coating on face 2 (inside the IGU).
• LAMINATION: can be laminated provided the coating is placed outside the laminate (coating on face 4 of the laminated pane).
• BENDING: the to-be-tempered version (II) can be bent; bending results depend on process/technology and trials should be performed for validation.
• ENAMELING: no general approval for enamelling of silver-based high-performance coatings.

AVAILABILITY & SUSTAINABILITY
The product is available worldwide. COOL-LITE® XTREME 61/29 (II) is also available on ORAÉ® low-carbon glass to combine performance and reduced carbon impact. This product is covered by a verified Environmental Product Declaration (EPD) and is Cradle to Cradle Certified® V4.0 Bronze.

PERFORMANCE
Extremely selective solar control glass combining medium/high visible transmission with a low solar factor to maximise daylight while limiting solar heat gain. Neutral appearance, low reflection and consistent colour deliver high aesthetic performance for large glazed façades.
