The SageGlass Difference SageGlass provides
control over a wide
range of solar
conditions, while static
glazing is optimal
for only one.
SageGlass offers
the ability to tint
or clear, harvesting
or rejecting the sun’s
heat as needed.
SageGlass has a
maximum UV
transmission that is
lower than the minimum
UV transmission of
static clear low-e glass.
SageGlass enables
nearly 100% fading
protection, with a low
end that far exceeds
the maximum of
conventional glass

*KDF measures the amount of the sun’s radiation transmitted through the glazing that causes fading. Fading protection is 1 – KDF.
The above data is based on 1” (25 mm) argon-filled IGU, calculated using Window 6.3.
