Save energy in winter and summer by placing Guardian Sun crystals in your windows.
The most balanced crystals on the market for your windows:
They filter solar radiation, improving comfort and saving on air conditioning in summer.
Thanks to the lowest U value in the market you will save on heating in winter and air conditioning in summer.
Durability and resistance against impacts and protection against UV rays. Also in acoustic insulation versions.
Properties of the Guardian Sun crystal
Optical and Thermal Values
The optical characteristics of a glazing are given by the type of layer selected, affecting almost imperceptibly the thickness of the glass.
As for the thermal values, they are related to the emissivity of the layer glass, as well as to the thickness of the chamber, varying up to 0.4 W / m2K if the Air is replaced by Argon.

Durability and resistance against impacts and protection against UV rays. Also in acoustic insulation versions.
* 90% gas filled index.
All values are nominal and are subject to product tolerance.
Light transmission: fraction of incident solar radiation in the visible range (380-780 nm) that passes through the glazing.
Solar factor: fraction of the incident solar ration that is transmitted entirely through glazing.
External reflection: fraction of reflected incident solar radiation.
U value: thermal transmittance. The amount of heat that is lost from the inside out through the glazing (in W / m2K).
