When to determine the thermal transmittance of a front one of the parameters to be considered is the solar factor normal incidence semitransparent parts of it (usually glass windows and skylights).
This parameter is defined as the ratio between the total energy that enters the premises through the glazing and the total energy incident on its outer surface perpendicular.
The local total energy coming through the glazing is the sum of the energy transmitted and the energy absorbed by the glass and subsequently transmitted into the local convection.
is represented by the letter g and its value is between 0 and 1. His method of calculation is described in ISO 15099: 20003.
The lower the solar factor greater fraction of incident solar energy is reflected outward by the glass favor a decrease in energy demand refrigeración.Los crystals have lower values \u200b\u200bof the solar factor is the so-called low-emissive .
can also change the solar factor by using solar blade attached to them, are composed of a polyester substrate to which it applies a scratch-resistant acrylic coating and abrasion on one side , while the other applies an adhesive layer and a shield to be rejected when they applied to the glass.
The adhesive used is a transparent substance, optically neutral that is activated on contact with water, forming a perfect marriage between glass and the sheet during installation. This adhesive provides a strong bond between glass and film while providing transparency and longevity to the installation.
