Solar Control Glass - Cool-Lite Xtreme 60/28 II

Extremely high selectivity solar control glass blocks 72% of the suns heat & allows 61% of the light into the room

COOL-LITE XTREME 60/28 and 60/28 II are the latest innovations in high performance solar control coatings. The coatings are applied to PLANICLEAR clear float glass by cathodic sputtering under vacuum conditions.

SGG COOL-LITE XTREME 60/28 and 60/28 II are the UK’s first triple-silver solar control coatings, which have the highest selectivity (the ratio of visible light to solar heat gain) in the SGG COOL-LITE range. The coatings are always placed on face 2 of a double-glazed unit.
