Thermal system solar controller COOL-LITE® KNT 140

Product description
COOL-LITE® KNT 140 is a single-silver solar protection coating in the COOL-LITE® KNT family. The ‘T’ denotes temperable: the product can be used annealed or heat-treated for greater processing and design flexibility. It delivers balanced solar protection while maintaining neutral visual appearance and high daylight transmission, suitable for architectural glazing in façades, skylights and interior partitions.

Benefits & Applications
COOL-LITE® KNT 140 is intended to reduce cooling, heating and lighting loads while maximizing natural light for comfortable indoor environments.

• Aesthetic: neutral appearance for clear outside views
• Comfort: continuous solar control helping to lower air-conditioning demand
• One stock: temperable solution offering annealed and heat-treated options from a single product for stock and design flexibility

Typical applications include non-residential buildings (office façades, airports, retail, showrooms, gymnasiums, atria) and residential projects requiring controlled solar gain and preserved daylight.

Appearance
COOL-LITE® KNT 140 provides a neutral visual tint suited to architectural glazing specifications.
