ONE MARKET, MANY VARIABLES
There are many variables to consider when selecting the joinery system you will offer. Among the most important:
CLIENT REQUIREMENTS
It is unquestionably necessary to reconcile requirements. Maximum performance is not always the variable that primarily influences the buyer’s choice. Without disregarding compliance with the minimum requirements set by the applicable regulations, other parameters very often may prevail as well, such as better passage, cost savings, etc.
WHERE JOINERY IS INSTALLED
It is unquestionably necessary to reconcile requirements. Maximum performance is not always the variable that primarily influences the buyer’s choice. Without disregarding compliance with the minimum requirements set by the applicable regulations, other parameters very often may prevail as well, such as better passage, cost savings, etc.
Climate zones determine the characteristics of joinery in in accordance with the obligations imposed by legislation.
It is equally important to assess the wind zone in which the the joinery installed, which especially affects the resistance air and water.
BUILDING TYPE
Based on the intended purpose of the structure, acoustic the reduction value of the façade is required from
changes in legislation. Of course, for the lift- sliding windows, which otherwise represent a significant
part of the facade, the value of noise reduction is especially important.

Glass performance, terms
Key Notes (EN)
The calculations and terminology in this report are based on EN 410:2011 / EN 673:2011. The performance values shown above are nominal values for the centre of glass, without spacer system or framing. Solar Factor (g) and Secondary Heat Transfer (qi) are not available for sloped glazing, because the standard does not prescribe a calculation method for these properties. The KIWA logo and KIWA Validation Report MD - 14/477/GL are presented as proof of validation of the Guardian Performance Calculator software, program version 4.1, for performing calculations of luminous and solar characteristics of glazing and thermal transmittance, in accordance with EN 410:2011 and EN 673:2011.
Laminated elements:
The Performance Calculator enables the user to model a wide range of laminated glass configurations using different float glass substrates, coatings, and interlayer materials, including configurations in which the coating faces the interlayer. It is the user’s responsibility to determine whether the laminated glass configuration meets the relevant regional standards and complies with applicable laminated glass safety regulations. In addition, when the laminated glass configuration includes a coating facing the interlayer material, there may be a reduction in thermal insulation performance and a change in color compared with non-embedded coated glass.
Non-reflective products (translucent or diffuse):
The performance assessment for non-specular (translucent or diffuse) materials, such as translucent interlayers, acid-etched glass surfaces, or surfaces with ceramic frit, is limited by current experimental technologies. Since measurements physically capture only part of the resulting radiation, the calculated performance results provided herein and based on such measurements are not compliant with any standard (including EN 410) and may be used only as a general reference. Actual values may vary significantly depending on the exact manufacturing process, as well as the type, thickness, and color of the non-specular material used.
Explanation of Terms in accordance with EN 410:2011/EN 673:2011
Visible Light Transmittance (Tv, %) is the percentage of incident light in the wavelength range from 380 nm to 780 nm that passes through the glass.
Ultraviolet (UV) Transmittance (Tuv, %) is the percentage of the incident UV component of solar radiation, in the wavelength range from 280 nm to 380 nm, that passes through the glass.
Solar Energy Direct Transmittance (Te, %) refers to the percentage of incident solar energy in the wavelength range of 300 nm to 2500 nm that is directly transmitted by the glass. Visible Light Reflectance Outdoors/Indoor (Rv out/in, %) refers to the percentage of incident visible light directly reflected by the glass.
Solar Direct Reflectance Outdoors/Indoors (Re out/in, %) indicates the percentage of incident solar energy that is directly reflected by the glass.
Solar Energy Absorptance (Ae, %) is the share of the sun’s energy absorbed by the glass.
U-Value (Ug, W/m2 K) is the glazing parameter that describes heat transfer through the central area of the glazing, i.e. without edge effects, and represents the steady-state heat transfer rate density per temperature difference between the ambient temperatures on each side. Temperature differential according to standard conditions: ∆T=15K°. The lower
the higher the value, the greater the insulating value. EN 673 specifies the value with 1 decimal place.
The value is also given with 3 decimal places for reference purposes.
Solar Factor, or Total Solar Energy Transmittance, or g-value (g%) refers to the total amount of solar radiation that passes through the glass.
Shading Coefficient (sc) is the Solar Factor divided by 0.87. It measures solar heat gain, referenced to 3 mm clear glass, which has the assigned value of 1.00.
Secondary Heat Transfer Coefficient (qi) is the result of heat transfer through convection and long-wave IR radiation of the portion of the incident solar radiation that has been absorbed by the glazing.
Colour Rendering Index in transmission, D65 (Ra) is the change in an object’s colour resulting from light being transmitted through the glass.
Important notes (SR)
Calculations and terms in this report are based on EN 410:2011/EN 673:2011. The performance values shown above are nominal values for the center of glass, without taking the spacer system or frame into account. The values of the solar factor (g) and the secondary heat transfer coefficient (qi) are not available for glazing installed at an angle because the standard does not define a calculation method.
The KIWA logo and “KIWA Validation Report MD - 14/477/GL” are available as proof of validation of the “Guardian Performance Calculator” program, version 4.1, for performing calculations of glazing characteristics and heat transmission according to standards EN 410:2011 and EN 673:2011.
Laminated products:
It is not guaranteed that the modeled laminated configurations will comply with the relevant safety regulations for laminated glass, unless expressly declared for Guardian products. It is the customer’s responsibility to determine whether the final laminated product should be certified in accordance with the relevant standards, and to ensure compliance with all safety regulations for laminated glass. As a result of laminating coated glass where the coating faces the PVB interlayer (due to contact between the interlayer and the coating), the following may occur (including, but not limited to): a significant reduction in safety performance for some combinations of coatings and interlayers, a loss of thermal insulation performance on the surface in contact with the interlayer, noticeable color change, and other performance degradations.
Translucent products (matt or diffuse):
Performance measurement for opaque materials such as semi-transparent interlayers or acid-etched glass, or ceramic-enamelled surfaces, is limited by current experimental technologies. Since the measurements cover only part of the spectrum, the calculated performance stated here is based on the aforementioned measurements, is not in accordance with any standard (including EN 410) and can be used only as a general reference. Actual values may differ significantly due to the manufacturing process as well as the type, thickness and color of the semi-transparent material used. Explanation of terms according to EN 410:2011/EN 673:2011
Visible light transmission (Tv, %) is the percentage of light with a wavelength between 380 nm and 780 nm that passes through the glass.
Ultraviolet (UV) transmittance (Tuv, %) is the percentage of light with a wavelength between 280 nm and 380 nm that is transmitted through the glass and originates from solar radiation (the UV component of solar radiation).
Direct transmittance of solar energy (Te, %) is the percentage of light with a wavelength between 300 nm and 2500 nm that is directly transmitted through the glass.
Visible light reflectance outside/inside (Rv out/in, %) is the percentage of visible light directly reflected from the glass.
Solar direct reflection exterior/interior (Re out/in, %) is the percentage of solar energy reflected by the glass.
Solar energy absorption (Ae, %) is the percentage of solar energy that the glass absorbs. U-value (Ug, W/m2 K) characterizes the heat transfer through the central part of the glass (glazing), i.e. the temperature on each side of the glass, without taking into account the edge effect

For information purposes, the value is also available in a display with 3 decimal places. Solar factor or Total solar energy transmission or g-value (g%) is the total solar energy transmitted through the glass.
Shading factor (sc) Solar factor divided by 0.87. Solar gain for clear glass of thickness 3 mm of the specified value 1.00.
The secondary heat transfer coefficient (qi) is the result of heat transfer by convection and long-wave IR radiation of part of the energy previously absorbed by the glass. Color rendering index in transmission, D65 (Ra) is the change in the color of an object as a result of light passing through the glass.
