Thermal system solar controller COOL-LITE® SKN 175

PRODUCT DESCRIPTION
COOL-LITE® SKN 175 and SKN 175 II are solar-control coated glass products offered in annealed (SKN 175) and to-be-tempered (SKN 175 II) versions. They provide a high visible light transmission (TL = 70%) combined with a low solar factor (g = 35%), resulting in a selectivity of 2.00 suitable for daylight-focused façades and glazing applications.

BENEFITS & APPLICATIONS

• Contributes to reduced energy demand and lower CO2 emissions through controlled solar gain.
• Suitable for a wide range of building types: offices, mixed-use, education and healthcare, for both new-build and refurbishment projects.
• Supports daylighting strategies while controlling solar heat load for occupant comfort and energy efficiency.
• Compatible with standard glass processing and temporary surface protection (EASYPRO®).

APPEARANCE
COOL-LITE® SKN 175 & 175 II deliver neutral colour rendering across viewing angles with low external reflection and consistent optical properties.

SUSTAINABILITY & CERTIFICATION
The product is covered by a verified Environmental Product Declaration (EPD) and holds Cradle to Cradle Certified® V4.0 Bronze.

TECHNICAL INFORMATION
RANGE:
SUBSTRATE: PLANICLEAR® (clear glass); DIAMANT® (extra clear glass); ORAÉ® (low-carbon glass)
THICKNESS: From 4 mm to 10 mm; to-be-tempered version up to 12 mm
SIZE: Standard jumbo 3.21 x 6.00 m; standard stock sizes; overlength up to 18 m (to-be-tempered)

PROCESSING

• ANNEALED: available in annealed condition (SKN 175).
• HEAT-TREATMENT: to-be-tempered version (SKN 175 II) must be tempered to reach specified performance; delivered with EASYPRO® temporary surface protection. Compatible with Heat Soak Test.
• EDGE DELETION: coating edge deletion is compulsory before assembly.
• INSULATED GLAZING UNIT (IGU): assembly into IGU is required with the coating on face 2 (inside the IGU).
• LAMINATION: suitable for lamination when the coating is placed outside the laminate (coating on face 4 of the laminated pane).
• BENDING: to-be-tempered version (II) can be bent; bending outcomes depend on process and must be validated by trials.
• ENAMELING: no general approval exists for enameling of silver-based high-performance coatings.
• Annealed and to-be-tempered versions provide comparable optical and solar performance and show compatible outdoor reflection behaviour.

AVAILABILITY
