KN 177 II SYMPHONY

COOL-LITE^® KN 177 II SYMPHONY is a new „to be tempered” reference, that highly performs in terms of light transmission (TL% = 70% for DGU and 63% for TGU), quality that turns out to be most efficient glass type in the areas where the new building project does not benefit of a high level of natural light (Northern areas, mountain areas or mostly cloudy areas).

Another main benefit of COOL-LITE^® KN 177 II SYMPHONY glass comes from the balance between the thermal comfort and the optical performances, such as the efficient capturing of natural light and a high fidelity of the natural colours, parameters requested by premium buildings.

Its advanced thermal insulation achieves a Ug-value of 1.0 W/m²K in a standard IGU with 16 mm Argon filled cavity, which is the best in this category of coatings. Due to this remarkable key factor, COOL-LITE^® KN 177 II SYMPHONY glass provides thermal comfort irrespective of season, but sustainable indoor spaces, as well.

The long term energy efficiency generates an optimal and convenient exploitation of the building, with low heating and cooling costs. As specific to COOL-LITE KN II range, this type of glass complies with the new NZEB requirements, its energy efficiency being an important criteria for the certification of green buildings, as LEED and BREEAM.

The buildings where COOL-LITE^® KN 177 II SYMPHONY glass is used, benefit of a neutral outside aesthetics, with slight silver reflections, while, in transmission, it is a neutral one, ideal for any modern architectural project.

COOL-LITE® KN 177 II SYMPHONY stands out due to the veracity of the hues and the refinement of the details, and is the outcome of centuries-old experience combined with cutting-edge technologies that Saint-Gobain uses to produce its glass.

If used for façades, this glass is suitable for:

-curtain walls

-roofs

-skylights

Main buildings where suitable:

-office buildings

-airports

-gyms and showrooms

-shopping malls

-HORECA buildings

-spectacular residential compounds

COOL-LITE® KN 177 II SYMPHONY glass is the optimal choice for shadowed areas or where the environment does not benefit of a high level of natural light.

COOL-LITE® KN 177 II SYMPHONY glass is produced in Jumbo sheets sized 6000 x 3210 mm, in three available thicknesses (6, 8, 10) with EASYPRO®. 

Split dimensions or other thicknesses: on demand

Substrate: PLANICLEAR® and/or DIAMANT® flat glass

COOL-LITE® KN 177 II SYMPHONY can be smoothly processed. It is a coating which can be subject to all types of processing, such as: 

-Tempering: the coating must be tempered to achieve its performances and aesthetics. EASYPRO® helps for a better, easier processability.

-Insulating glass units: It must always be assembled in IGU, with the coating on face #2.

-Curving: with some certain limitations, technical consultancy provided on request 

-„Heat Soak” testing: recommended to be done for all tempered glass, in order to avoid spontaneous breakages due to NiS inclusions.

-Laminating: with the coating not in contact with the PVB film. The glass must be heat treated before lamination.

Technical key performances:

• LIGHT TRANSMISSION: very high (TL% = 70% for DGU and 63% for TGU), for urban integration even in Northern areas, cloudy regions or mountain projects.

• AESTHETICS: The medium values for the outside and inside light reflectivity (ranged between 22-26%) combined with the fidelity of the colors in transmission generate a great potential for COOL-LITE® KN 177 II SYMPHONY to be used in projects that can combine the creativity with the optimal urban comfort.

• THERMAL INSULATION: Ug-value of 1.0 W/m²K generates bright spaces with indoor thermal comfort, suitable to buildings efficiently exploited energy-wise.

• VISUAL COMFORT: is given by the high fidelity of the natural colors, highly visible in transmission.
