Solar Control Glass is Flat Glass’s heat and solar control glass. It is a type of coated glass that can perform heat insulation and solar control at the same time. Thanks to the insulation it provides for cooling in summer and heating in winter, it saves energy by reducing expenses. This glass, especially developed for residences, is used in house windows. It provides at least 2 times energy saving compared to normal flat glass. It is used in residential windows as double glazing.
Insulated glazing made with Solar Control Low-E Glass reduces heat losses by 77% compared to single glazing and 50% compared to ordinary double glazing, reducing fuel costs in winter; It reduces solar heat input by 40% compared to ordinary double glazing, saving cooling costs in summer.
Advantages of Solar Control Glass
- It provides solar control and heat insulation together with a single coating on the glass.
- It reduces fuel and air conditioning expenses.
- It does not compromise on transparency and natural daylight.
- It delays condensation on the glass surface.
- It prevents window fronts from being cold in winter and hot in summer.
- It prevents the passage of ultraviolet (UV) rays by 91%, which causes the colors of goods and fabrics to fade.
- Compared to ordinary double glazing, the expenditure you will make for insulated glass produced using Solar Control Low-E Glass will return in 1-2 years with the savings you will make on heating and cooling costs.
Solar Control Low-E Glass, which is mostly preferred in residences and small and medium-sized commercial buildings, offers comfortable living spaces to users with its heat and solar control feature.
Solar Control Low-E Glass is an off-line coated glass obtained by applying a thin metal/metal oxide layer on flat glass by electron scattering method in a vacuum environment.
“Daylight” and “Solar Energy” values were calculated in the “TNO Science and Industry“ – WIS 3.01 package program, using spectral data measured in a laboratory environment in accordance with EN 410 standard.
The U value, which is the heat transmittance coefficient, was calculated with the WIS 3.01 program in accordance with the EN 673 standard. The emissivity values used in the U value calculation were measured in accordance with EN 673 (Annex A) and EN 12898 in the laboratory environment.
The risk of thermal breakage may arise due to factors such as partial exposure to solar radiation along the surfaces of the glasses, temperature differences between day and night, heat absorption coefficients of the glasses or the type of joinery. Depending on these factors, it may be necessary to use tempered or partially tempered glass.
Daylight Transmittance: It is the percentage of light entering the glass that passes through the glass.
Daylight Reflection (outer): The percentage of light incident on the glass that is reflected back by the glass.
Solar Energy Total Permeability: It is the percentage of the total solar energy on the glass that enters. A lower solar total transmittance value means better solar control.
Shading Coefficient: It is the comparison of the total solar energy transmittance with 3 mm colorless glass. A lower shading coefficient means better sun control.
Thermal Permeability Coefficient: It is the criterion of thermal insulation in glasses. A lower U-value means better thermal insulation, less heating costs and more winter comfort.
Use of Solar Control Glass
Solar Control Low-e Glass which is used as 4 and 6 mm non-tempered, is used as double glazing in residential windows.
Solar Control Low-e Glass which we supply as 6 and 8 mm, can be tempered and used on facades.
It provides visual integrity by hiding building elements such as columns, beams, parapet walls, suspended ceilings and installation gaps in buildings with curtain walls, thanks to its reflective feature.
Due to its reflective feature, it creates a mirror effect when viewed from the side where the light is strong. For example, it provides a one-way view from the inside to the outside during the daytime and, on the contrary, from the outside to the inside at night.
